Box 2546 .- 452 Ellis Street Augusta, Georgia 30903 , ~ .. June 24, 2005 2003-259 I I I I I I I I I I I I I I I I I I I I Addendum No. 1 to the Contract Documents and Drawings for the construction of PROJECT NO. 80501 SPIRIT CREEK PUMP STATION Our File No. 2003-259 August 26, 2005 1. The following questions from the Pre-Bid Conference and subsequent submitted questions have been addressed: A. Can the bid form be simplified and/or the project be changed to lump sum? No, the current setup of the bid form and project structure will remain the same. B. Can the contract completion time be extended to 395 days and/or the liquidated damaged be reduced? No, the current schedule is what will be required to meet the projects scheduling goals and an E.P.D. mandated completion date; therefore, both the contract completion time and liquidated damages will remain the same. C. Can the electrical building be moved further away from the wet well in order to facilitate simultaneous construction without shoring? No, the electrical building shall remain in the location shown on the plans, which was strategically chosen due to the limitations of the variable frequency drives. D. Do the specifications allow for the use of other hatch manufactures besides Flygt which is noted on the drawings? Yes, as also noted on the plans (Sheet C6.1, "Schedule of Access Hatches", Note 2), equivalent hatches will be considered during the equipment submittal phase after the contract is awarded. E. Will it be acceptable to allow the precast manufacturer to precast an extended base onto the vaults/structures in lieu of doweling and pouring a cast-in-place footing around the base as shown on the drawings (Sheet C7.1)? Yes, as long as such a structure can be delivered to the site; it will be acceptable. It was our intention to provide an alternative to pre-casting the extended base because of the width (15'-4"), which could be a delivery issue. Addendum No. 1 Page 1 of 17 I I I I I I I I I I I I I I I I I I I F.. It appears that there will be a significant amount of dirt to waste from the site cut and pump station excavation. I What are the current plans for the wasting of this amount of dirt? The Contractor will not be allowed to waste excess material on site or on any nearby City property/easements. Instead, excess material shall be legally disposed of at an offsite location approved by the Owner. All associated costs shall be the Contractor's responsibility and should be included in the lump sum pay item for Grading. G. Reference Specification Section 02250 regarding the temporary bypass pumping system(s) for this project. Please provide the required capacity(ies) for the bypass pumping system(s). As mentioned in the pre-bid meeting, the only by-pass pumping required will be for the existing 24" gravity sewer shown on the site plans. The flow on this line should be minimal. According to the Owner, there are less than 10 homes tied onto this line. However, it is recommended that the Contractor visit the site to observe and verify the flows. H. Reference Specification Subsection 05400-1.4B regarding pre-approval of light gauge steel truss frame fabricators. Either provide a list of pre-approved fabricators or waive the requirement for this project. Eliminate the pre-approved requirement of light gauge steel truss frame fabricators as described in Specifications Subsection 05400-1.4B. The frame fabricators will be reviewed and approved during the material submittal phase after the contract is awarded. 1. Reference Specification Section 07195 regarding water repellant. What surfaces will require water repellant for this project? Specification Section 07195 is for application on surfaces of the electrical building only. This is in addition to the integral water repellent. J. Reference Page 04200-11 of the specifications and Drawings Sl.l - S4.1 regarding "Masonry Cell Insulation." Are the exterior walls of the electrical building to be filled with granular insulation? Yes, as stated on Page 04200-11 of the specifications, "Pour granular insulation into the cores of all exterior hollow masonry unit walls as shown to fill void spaces completely." "As shown" refers to all exterior hollow masonry unit walls shown on the Plans. Addendum No.1 Page 2 of 17 I I I I I I I I I I I I I I I I I I I K. Reference Specification Section 11300 regarding power requirements for valves. Please clarify. The specification s~ys all plug valves, control valves and sluice gates shall be designed for 460 volt, 3-phase operation; but not all plug valves \ on this job are electrically actuate~. Is this correct? This power requirement does not apply to the manual plug valves. L. Will any approved equals for plug valves, control valves, sluice gates, or hatches be added by addendum? No, due to time constraints all reviews and approvals for "equal" equipment will be done during the equipment submittal phase after the contract is awarded. M. References Drawing C2.2 and the Proposal Section of the Contract Documents regarding curb and gutter. Is there any curb and gutter on this project? There is no curb and gutter shown on the plans. However, it may be added in the field by the Owner's representative and is, therefore, in the Proposal Section. N. Reference Drawing C2.3 regarding influent 24" DIP and 24" DIP overflow line. Would you consider bringing these lines straight to the existing 24" sewer line and doghousing a manhole over the existing line to make the tie-ins? Since this is a unit price job, this could easily be changed in the field and may be a viable option for the influent line. However, this would not be possible with the overflow line because of invert elevation constraints. Any changes to the alignment shall be handled in the field. II.

TRAVELERS IMPORTANT DISCLOSURE NOTICE OF TERRORISM INSURANCE COVERAGE On November 26, 2002, President Bush sig~d into law the Terrorism Risk Insurance Act of ,2002 (the "Act"). The Act establishes a short-term program under which the Federal Government will share in the payment of covered losses caused by certain acts of international terrorism. We are providing you with this notice to inform you of the key features of the Act, and to let you know what effect, if any, the Act will have on your premium. Under the Act, insurers are required to provide coverage for certain losses caused by international acts of terrorism as defined in the Act. The Act further provides that the Federal Government will pay a share of such losses. Specifically, the Federal Government will pay 90% of the amount of covered losses caused by certain acts of terrorism which is in excess of an insurer's statutorily established deductible for that year. The Act also caps the amount of terrorism-related losses for which the Federal Government or an insurer can be responsible at $100,000,000,000.00, provided that the insurer has met its deductible. Please note that passage of the Act does not result in any change in coverage under the attached policy or bond (or the policy or bond being quoted). Please also note that no separate additional premium charge has been made for the terrorism coverage required by the Act. The premium charge that is allocable t6 such coverage is inseparable from and imbedded in your overall premium, and is no more than one percent of your premium.

INC., party of the second part, hereinafter called the CONTRACTOR. WITNESSETH, that the Contractor and the Owner, for the considerations hereinafter named, agree as follows: ARTICLE I - SCOPE OF THE WORK The Contractor hereby agrees to furnish all of the materials and all of the equipment and labor necessary, and to perform all of the work shown on the plans described in the specifications for the project entitled: BOND PROJECT 80501 SPIRIT CREEK PUMP STATION and in accordance with the requirements and provisions of the Contract Documents as defined in the General and Special Conditions hereto attached which are hereby made a part of this agreement. ARTICLE II - TIME OF COMPLETION -- LIOUIDATED DAMAGES The work to be performed under this Contract shall be commenced within ten ClQ) calendar days after the date of written notice by the Owner to the Contractor to proceed. The work shall be completed within Three Hundred (300) calendar days after the date of such notice and with such extensions of time as are provided for in the General Conditions. It is hereby understood and mutually agreed, by and between the Contractor and the Owner, that the date of beginning, rate of progress and the time for completion of the work to be done hereunder are ESSENTIAL CONDmONS of this Contract. Contractor agrees that said work shall be prosecuted regularly, diligently, and uninterruptedly at such rate of progress as will insure full completion there of within the time specified. It is expressly understood and agreed by and between the Contractor and the Owner, that the time for the completion of the work described herein is a reasonable time for the completion of the same, taking into consideration the average climatic range and construction conditions prevailing in this locality. IF THE CONTRACTOR SHALL NEGLECT, FAIL OR REFUSE TO COMPLETE THE WORK WITHIN THE TIME HEREIN SPECIFIED, then the Contractor does hereby agree, as a part of the consideration for the awarding of this contract, to pay to the Owner the sum of One Thousand Dollars ($1,000.00), not as a penalty, but as liquidated damages for such breach of contract as hereinafter set forth, for each and every calendar day that the Contractor shall be in default after the time stipulated in the contract for completing the work. A-I I I I I I I I I I I I I I I I I I 1 I The said amount is fixed and agreed upon by and between the Contractor and the Owner because of the impracticability and extreme difficulty of fixing and ascertaining the actual damages the Owner would, in such event, sustain, and said amounts shall be retained from time to time by the Owner from current periodical estimates. It is further agreed that time is of the essence of each and every portion of this contract and the specifications wherein a definite portion and certain length of time is fixed for the performance of any act whatsoever; and where under the contract an additional time is allowed for the completion of any work, the new time limit fixed by extension shall be the essence of the Contract. ARTICLE ill,. PAYMENT (A) THE CONTRACT SUM The Owner shall pay to the Contractor for the performance of the Contract the amount as stated in the Proposal and Schedule ofItems. No variations shall be made in the amount except as set forth in the specifications attached hereto. (B) PROGRESS PAYMENTS On no later than the fifth day of every month, the Contractor shall submit to the Owner an estimate covering the percentage of the total amount of the Contract which has been completed from the start of the job up to and including the last working day of the preceding month, together with such supporting evidence as may be required by the Owner and/or the Engineer. This estimate shall include only quantities in place and at the unit prices set forth in the bid schedule. On the vendor run following approval of the invoice for payment, the Owner shall after deducting previous payments made, pay to the Contractor 90% of the amount of the estimate on units accepted in place. The 10% retained percentage may be held by the Owner until the final completion and acceptance of all work under the Contract. ARTICLE IV - ACCEPTANCE AND FINAL PAYMENT (A) Upon receipt of written notice that the work is ready for final inspection and acceptance, the Engineer shall within 10 days make such inspection, and when he finds the work acceptable under the Contract and the Contract fully performed he will promptly issue a final certificate, over his own signature, stating that the work required by the Contract has been completed and is accepted by him under the terms and conditions thereof, and the entire balance found to be due the Contractor, including the retained percentage, shall be paid to the Contractor by the Owner within 15 days after the date of said final certificate. (B) Before final payment is due the Contractor shall submit evidence satisfactory to the Engineer that all payrolls, material bills, and other indebtedness connected with the work have been paid, except that in case of disputed indebtedness of liens of evidence of payment of all such disputed amounts when adjudicated in cases where such payment has not already been guaranteed by surety bond. A-2 I I I I I I I I I I I I I I I I I I I (C) The making and acceptance of the final payment shall constitute a waiver of all claims by the Owner other than those arising from unsettled liens, from faulty work appearing within 12 months after final payment, from requirements of the specifications, or from manufacturers' guarantees. It shall also constitute a waiver of all claims by the Contractor except those previously made and still unsettled. (D) If after the work has been substantially completed, full completion thereof is materially delayed through no fault of the Contractor, and the Engineer, so certifies, the Owner shall upon certification of the Engineer, and without terminating the Contract, make payment of the balance due for that portion of the work fully completed and accepted. Each payment shall be made under the terms and conditions governing final payment, except that it shall not constitute a waiver of claims.

November 26, 2002, President Bush signed into law the Terrorism Risk Insurance Act of ,2002 (the "Act"). The Act establishes a short-term program under which the Federal Government will share in the payment of covered losses caused by certain acts of international terrorism. We are provi~ing you with this notice to inform you of the key features of the Act, and to let you know what effect, if any, the Act will have on your premium. Under the Act, insurers are required to provide coverage for certain losses caused by international acts of terrorism as defined in the Act. The Act further provides that the Federal Government will pay a share of such losses. Specifically, the Federal Government will pay 90% of the amount of covered losses caused by certain acts of terrorism which is in excess of an insurer's statutorily established deductible for that year. The Act also caps the amount of terrorism-related losses for which the Federal Government or an insurer can be responsible at $100,000,000,000.00, provided that the insurer has met its deductible. . Please note that passage of the Act does not result in any change in coverage under the attached policy or bond (or the policy or bond being quoted). Please also note that no separate additional premium charge has been made for the terrorism coverage required by the Act. The premium charge that is allocable to such coverage is inseparable from and imbedded in your overall premium, and is no more than one percent of your premium. ILT-tOt8 (9/04) ~ ", . .

HUDGINS, ATTORNEY':IN-FACT I ' I I I I I I I I I I I I I I I I I I _ ST'PAUL IIIII'TRAVELERS IMPORTANT DISCLOSURE NOTICE OF TERRORISM INSURANCE COVERAGE On. November 26, 2002, President Bush signed into law the Terrorism Risk Insurance Act of ,2002 (the "Act"). The Act establishes a short-term program under which the Federal Government will share in the payment of covered losses caused by certain acts of international terrorism. We are providing you with this notice to inform you of the key features of the Act, and to let you know what effect, if any, the Act will have on your premium. Under the Act, insurers are required to provide coverage for certain losses caused by international acts of terrorism as defined in the Act. The Act further provides that the Federal Government will pay a share of such losses. Specifically, the Federal Government will pay 900/0 of the amount of covered losses caused by certain acts of terrorism which is hi excess of an insurer's statutorily established deductible for that year. The Act also caps the amount of terrorism-related losses for which the Federal Government or an insurer can be responsible at $100,000,000,000.00, provided that the insurer has met its deductible. Please note that passage of the Act does not result in any change in coverage under the attached policy or bond (or the policy or bond being quoted). Please also note that no separate additional premium charge has been made for the terrorism coverage required by the Act. The premium charge that is allocable to such coverage is inseparable from and imbedded in your overall premium, and is no more than one percent of your premium. . ILT-lOl8 (9/04) . r' . .

PROFESSIONAL's written decisions thereon will be final and binding upon OWNER and CONTRACTOR, unless, within ten days after the date of any such decision, either OWNER or CONTRACTOR delivers to the other party to the Agreement and to PROFESSIONAL written notice of intention to appeal from such a decision. Decisions on Disputes: 9.11. PROFESSIONAL will be the initial interpreter of the requirements of the Contract Documents and judge of the acceptability of the Work thereunder. Claims, disputes and other matters GC-34 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 relating to the acceptability of the Work or the interpretation of the requirements of the Contract Documents pertaining to the performance and furnishing of the Work and claims under Articles 11 and 12 in respect of changes to the Contract Price or Contract Time will be referred initially to PROFESSIONAL in writing with a request for a formal decision in accordance with this paragraph, which PROFESSIONAL will render in writing within a reasonable time. Written notice of each such claim, dispute and other matter will be delivered by the claimant to PROFESSIONAL and the other party to the Agreement promptly (but in no event later than thirty days after the occurrence of the event giving rise thereto) and written supporting data will be submitted to PROFESSIONAL and the other party within sixty days after such occurrence unless PROFESSIONAL allows an additional period of time to ascertain more accurate data in support of the claim. 9.12. When functioning as interpreter and judge under paragraphs 9.10 and 9.11, PROFESSIONAL will not show partiality to OWNER or CONTRACTOR and will not be liable in connection with any interpretation or decision rendered in good faith in such capacity. The rendering of a decision by PROFESSIONAL pursuant to paragraphs 9.10 and 9.11 with respect to any such claim, dispute or other matter (except any which have been waived by the making or acceptance of final payment as provided in paragraph 14.16) will be a condition precedent to any exercise by OWNER or CONTRACTOR of such rights or remedies as either may otherwise have under the Contract Documents or by Laws or Regulations in respect of any such claim, dispute or other matter. Limitations on PROFESSIONAL's Responsibilities: 9.13. Neither PROFESSIONAL's authority to act under this Article or elsewhere in the Contract Documents nor any decision made in good faith to exercise such authority shall give rise to any duty or responsibility of PROFESSIONAL to CONTRACTOR, any Subcontractor, any of their agents or employees. 9.14.

GC-35 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 ARTICLE 10--CHANGES IN THE WORK 10.1. Without invalidating the Contract, OWNER may at any time or from time to time order additions, deletions, or revisions in the Work. The OWNER shall provide CONTRACTOR with a proposal request, identifying the Work to be added, deleted or revised. Upon receipt, CONTRACTOR shall promptly submit a written proposal for the changed work prepared in accordance with Articles 11 and 12. If the proposal request calls only for the deletion of Work, the OWNER may order the partial suspension of any Work related to the proposed deletion, in which case CONTRACTOR must cease performance as directed; CONTRACTOR shall not be entitled to claim lost profits on deleted work. All changed Work shall be executed under the applicable conditions of the Contract Documents. 10.2. Additional Work performed by CONTRACTOR without authorization of a Change Order will not entitle CONTRACTOR to an increase in the Contract Price or an extension of the Contract Time, except in the case of an emergency as provided in Article 6. The effect of this paragraph shall remain paramount and shall prevail irrespective of any conflicting provisions contained in these Contract Documents. 10.3. Upon agreement as to changes in the Work to be performed, Work performed in an emergency as provided in Article 6, and any other claim of CONTRACTOR for a change in the Contract Time or the Contract Price, PROFESSIONAL will prepare a written Change Order to be signed by PROFESSIONAL and CONTRACTOR and submitted to OWNER for approval. 10.4. In the absence of an agreement as provided in 10.3, OWNER may, at its sole discretion, issue a Work Change Directive to CONTRACTOR. Pricing of the Work Change Directive will be in accordance with Section 11.3. The Work Change Directive will specify a price, and if applicable a time extension, determined to be reasonable by OWNER. If CONTRACTOR fails to sign such Work Change Directive, CONTRACTOR may submit a claim in accordance with Articles 11 and 12, but CONTRACTOR shall nevertheless be obligated to fully perform the work as directed by the Work Change Directive. 10.5. CONTRACTOR shall proceed diligently with performance of the Work as directed by OWNER, regardless of pending claim actions, unless otherwise agreed to in writing. 10.6. If notice of any change affecting the general scope of the Work or the provisions of the Contract Documents (including, but not limited to, Contract Price or Contract Time) is required by the provisions of any Bond to be given to a surety, the giving of any such notice will be CONTRACTOR's responsibility, and the amount of each applicable Bond will be adjusted accordingly. GC-36 I I I I I I I I I I I I I I 1 I I I I Revision Date August 2001 ARTICLE 11-CHANGE OF CONTRACT PRICE 11.1. The Contract Price constitutes the total compensation (subject to written authorized adjustments) payable to CONTRACTOR for performing the Work. All duties, responsibilities and obligations assigned to or undertaken by CONTRACTOR shall be at CONTRACTOR's expense without change in the Contract Price. 11.2. The Contract Price may only be changed by a Change Order or by a Written Amendment. Any claim for an increase or decrease in the Contract Price shall be based on written notice delivered by the party making the claim to the other party and to PROFESSIONAL promptly (but in no event later than thirty days) after the occurrence of the event giving rise to the claim and stating the general nature of the claim. Notice of the amount of the claim with supporting data shall be delivered within sixty days after such occurrence (unless PROFESSIONAL allows an additional period of time to ascertain more accurate data in support of the claim) and shall be accompanied by claimant's written statement that the amount claimed covers all known amounts (direct, indirect and consequential) to which the claimant is entitled as a result of the occurrence of said event. All claims for adjustment in. the Contract Price shall be determined by PROFESSIONAL in accordance with paragraph 9.11 if OWNER and CONTRACTOR cannot otherwise agree on the amount involved. No claim for an adjustment in the Contract Price will be valid if not submitted in accordance with this paragraph 11.2. 11.3. The value of any Work covered by a Change Order or of any claim for an adjustment in the Contract Price will be determined by the following procedures: 11.3.1. Designated Unit Price (Field Measure). CONTRACTOR and OWNER recognize and acknowledge that the quantities shown for those items designated in the Bid Proposal as unit price items are approximations prepared by OWNER for bid purposes and that.the actual compensation payable to CONTRACTOR for the utilization of such items is based upon the application of unit prices to the actual quantities of items involved as measured in the field and required to complete the Work as originally defined in the Contract Documents. 11.3.2. When it is determined by OWNER that an addition, deletion, or revision to the Work, as defined in these Contract Documents, is required and affects the quantities required for items designed in the Bid Proposal as unit price items, CONTRACTOR and OWNER agree that the compensation payable to CONTRACTOR for such unit price items shall be adjusted accordingly by a Change Order based upon the application of the appropriate unit prices shown in the Bid Proposal to the quantity of the unit price item required to complete the Work as defined in the Contract Documents. 11.3.3. Other Unit Prices. For items not designated in the bid proposal as unit prices, OWNER and CONTRACTOR may establish unit prices as agreed on by Change Order. GC-37 I I I I I I I I I I I 1 I I I I I I I Revision Date August 2001 11.3.4. Lump Sum.

If the pricing methods specified in 11.3 are inapplicable, or if the parties are unable to agree on a price for the changed work, a reasonable price for the same shall be established by OWNER in accordance with 11.4 and 11.5. OWNER shall then process a unilateral Change Order, specifying the said reasonable price, in accordance with 11.4 through 11.6. CONTRACTOR shall perform the Work as directed in the Change Order. 11.3.6. Failure on the part of CONTRACTOR to construct any item to plan or authorized dimensions within the specification tolerances shall result in: reconstruction to acceptable tolerances at no additional costs to OWNER; acceptance at no pay; or acceptance at reduced final pay quantity or reduced unit price, all at the discretion of OWNER. Determinations of aggregate monetary change for items identified as lump sum quantities shall be made by OWNER based upon an analysis of the scope of CONTRACTOR's failure to construct to plan or authorized dimensions. Cost of the Work: 11.4. The term Cost of the Work means the sum of all costs necessarily incurred and paid by CONTRACTOR in the proper performance of the Work.

Cash Allowances: 11.8. It is understood that CONTRACTOR has included in the Contract Price all allowances so named in the Contract Documents and shall cause the Work so covered to be done by such Subcontractors or Suppliers and for such sums within the limit of the allowances as may be acceptable to PROFESSIONAL CONTRACTOR agrees that: 11.8.1. The allowances include the cost to CONTRACTOR (less any applicable trade discounts) of materials and equipment required by the allowances to be delivered at the site and all applicable taxes; and 11.8.2. CONTRACTOR's costs for unloading and handling on the site, labor, installation costs, overhead, profit and other expenses contemplated for the allowances have been included in the Contract Price and not in the allowances. No demand for additional payment on account of any thereof will be valid. Prior to final payment, an appropriate Change Order will be issued as recommended by PROFESSIONAL to reflect actual amounts due CONTRACTOR on account of Work covered by allowances, and the Contract Price shall be correspondingly adjusted. Unit Price Work: 11.9.1. Where the Contract Documents provide that all or part of the Work is to be Unit Price Work, initially the Contract Price will be deemed to include for all Unit Price Work an amount equal to the sum of the established unit prices for each separately identified item of Unit Price Work times the estimated quantity of each item as indicated in the Agreement. The estimated quantities of items of Unit Price Work are not guaranteed and are solely for the purpose of comparison of Bids and determining an initial Contract Price. Determinations of the actual quantities and classifications of Unit Price Work performed by CONTRACTOR will be made by PROFESSIONAL in accordance with Paragraph 9.10. 11.9.2. Each unit price will be deemed to include an amount considered by CONTRACTOR to be adequate to cover CONTRACTOR's overhead and profit for each separately identified item. 11.9.3. Where the quantity of any item of Unit Price Work performed by CONTRACTOR differs materially and significantly from the estimated quantity of such item indicated in the Agreement GC-42 I I I I I I I I I I I I 1 I I I I I I Revision Date August 2001 and there is no corresponding adjustment with respect to any other item of Work and if CONTRACTOR believes that CONTRACTOR has incurred additional expense as a result thereof, CONTRACTOR may make a claim for an increase in the Contract Price in accordance with Article 11 if the parties are unable to agree as to the amount of any such increase. GC-43 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 ARTICLE 12--CHANGE OF CONTRACT TIME 12.1. The Contract Time may only be changed by a Change Order. Any request for an extension in the Contract Time shall be made in writing and delivered to PROFESSIONAL and OWNER within seven (7) calendar days of the occurrence first happening and resulting in the claim. Written supporting data will be submitted to PROFESSIONAL and OWNER within fifteen (15) calendar days after such occurrence unless the OWNER allows additional time. All claims submitted by CONTRACTOR for adjustments to the Contract Time must set forth in detail the reasons for and causes of the delay and clearly indicate why the subject delay was beyond CONTRACTOR's control or fault. 12.2. If CONTRACTOR is delayed at any time in the performance, progress, commencement, or completion of the Work by any act or neglect of OWNER or PROFESSIONAL, or by an employee of either, or by any separate CONTRACTOR employed by OWNER, or by changes ordered in the Work, or by labor disputes, fIre, unavoidable casualties, utility conflicts which could not have been identified or foreseen by CONTRACTOR using reasonable diligence, or any causes beyond CONTRACTOR's control or fault, then the Contract Time shall be extended by Change Order for such reasonable time as OWNER may determine. CONTRACTOR shall be entitled to an extension of time for such causes only for the number of days of delay which OWNER may determine to be due solely to such causes and only to the extent such occurrences actually delay the completion of the Work and then only if CONTRACTOR shall have strictly complied with all the requirements of the Contract Documents. Provided, however, notwithstanding anything in the Contract Documents tothe contrary, no interruption, interference, inefficiency, suspension or delay in the performance, progress, commencement or completion of the Work for any cause whatsoever, including those for which OWNER or PROFESSIONAL may be responsible in whole or in part, shall relieve CONTRACTOR of its duty to perform or give rise to any right to damages or additional compensation from OWNER. CONTRACTOR's sole and exclusive remedy against OWNER for interruption, interference, inefficiency, suspension or delay of any aspect of the Work shall be the right to seek an extension to the Contract Time in accordance with the procedures set forth herein.

All unsatisfactory Work, all faulty Work and all Work not conforming to the requirements of the Contract Documents or such inspections, tests, approvals, or all applicable building, construction and safety requirements shall be considered defective. Notice of all defects shall be given to CONTRACTOR by PROFESSIONAL. All defective work, whether or not in place, may be rejected, corrected, or accepted as provided in this Article. Access to Work: 13 .2. For the duration of the Work, PROFESSIONAL and its representatives, other designated representatives of OWNER, and authorized representatives of any regulatory agency shall at all times be given access to the Work. CONTRACTOR shall provide proper facilities for such access and observation of the Work and also for any inspection or testing by others. Tests and Inspections: 13.3.

For all required inspections, tests, and approvals on any Work prepared, performed, or assembled away from the site, CONTRACTOR will furnish PROFESSIONAL with the required Certificates of Inspection, testing, or approval. All such tests will be in accordance with the methods prescribed by the American Society for Testing and Materials or such other applicable organizations as may be required by law or the Contract Documents. Materials or Work in place that fail to pass acceptability tests shall be retested at the direction of PROFESSIONAL and at CONTRACTOR's expense. GC-45 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 13.5. All inspections, tests or approvals other than those required by Laws or Regulations of any public body having jurisdiction shall be performed by organizations acceptable to OWNER and CONTRACTOR (or by PROFESSIONAL if so specified). 13.6. If any Work (including the work of others) that is to be inspected, tested or approved is covered without written concurrence of PROFESSIONAL, it must, if requested by PROFESSIONAL, be uncovered for observation. Such uncovering shall be at CONTRACTOR's expense unless CONTRACTOR has given PROFESSIONAL timely notice of CONTRACTOR's intention to cover the same and PROFESSIONAL has not acted with reasonable promptness in response to such notice. 13.7. Neither observations by PROFESSIONAL or Project Manager nor inspections, tests, or approvals by persons other than CONTRACTOR shall relieve CONTRACTOR of its obligations to perform the Work in accordance with the requirements of the Contract Documents. Uncovering Work: 13.8. If any Work required to be inspected, tested or approved is covered prior thereto without the prior written approval of PROFESSIONAL, or if any Work is covered contrary to the request of PROFESSIONAL, the Work shall, if requested by PROFESSIONAL, be uncovered for observation, inspection, testing or approval and replaced at CONTRACTOR's expense. 13.9. If PROFESSIONAL considers it necessary or advisable that covered Work be observed by PROFESSIONAL or inspected or tested by others, CONTRACTOR, at PROFESSIONAL's request, shall uncover, expose or otherwise make available for observation, inspection or testing as PROFESSIONAL may require, that portion of the Work in question, furnishing all necessary labor, material and equipment.

If, however, such Work is not found to be defective, CONTRACTOR shall be allowed an increase in the Contract Price or an extension of the Contract Time, or both, directly attributable to such uncovering, exposure, observation, inspection, testing and reconstruction, and, if the parties are unable to agree as to the amount or extent thereof, CONTRACTOR may make a claim therefor as provided in Articles 11 and 12. OWNER May Stop the Work: 13.10. When Work is defective or when CONTRACTOR fails to supply sufficient skilled workmen or suitable materials or equipment or make prompt payments to Subcontractors for labor, materials, or equipment or if CONTRACTOR violates any provisions of these Contract Documents, GC-46 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 OWNER may order CONTRACTOR to stop the Work until the cause for such order has been eliminated. However, this right of OWNER to stop the Work shall not give rise to any duty on the part of OWNER to exercise this right for the benefit of CONTRACTOR or any other party. CONTRACTOR shall have no right to claim an increase in the Contract Price or Contract Time or other damages for a stop work order under this paragraph. Correction or Removal of Defective Work: 13.11. When directed by PROFESSIONAL, CONTRACTOR shall promptly, without cost to OWNER and as specified by PROFESSIONAL, either correct the defective Work whether fabricated, installed, or completed, or remove it from the site and replace it with non-defective Work.

All direct and indirect costs of such correction shall be paid by CONTRACTOR or deducted from payment to CONTRACTOR. CONTRACTOR will also bear the expense of correcting or removing and replacing all Work of others destroyed or damaged by the correction, removal, or replacement of the defective Work. One Year Correction Period: 13.12.

If CONTRACTOR does not promptly comply with the terms of such instructions, OWNER may have the defective Work corrected, removed, or replaced. All direct, indirect and consequential costs of such removal and replacement (including but not limited to fees and charges of engineers, architects, attorneys and other professionals) will be paid by CONTRACTOR. Acceptance of Defective Work: 13.13. If, instead of requiring correction or removal and replacement of defective Work, OWNER (and, prior to PROFESSIONAL's recommendation of final payment, PROFESSIONAL) prefers to accept it, OWNER may do so. CONTRACTOR shall bear all direct, indirect and consequential costs attributable to OWNER's evaluation of and determination to accept such defective Work (such costs to be approved by PROFESSIONAL as to reasonableness and to include but not be limited to fees and charges of engineers, architects, attorneys and other professionals). If any such acceptance occurs prior to PROFESSIONAL's recommendation of final payment, a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work, GC-47 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 and OWNER shall be entitled to an appropriate decrease in the Contract Price, and, if the parties are unable to agree as to the amount thereof, OWNER may make a claim therefor as provided in Article 11. If the acceptance occurs after such recommendation, an appropriate amount will be paid by CONTRACTOR to OWNER. OWNER May Correct Defective Work: 13.14. If CONTRACTOR fails within a reasonable time after written notice of PROFESSIONAL to proceed to correct defective Work or to remove and replace rejected Work as required by PROFESSIONAL in accordance with paragraph 13.11, or if CONTRACTOR fails to perform the Work in accordance with the Contract Documents, or if CONTRACTOR falls to comply with any other provision of the Contract Documents, OWNER may, after seven days' written notice to CONTRACTOR, correct and remedy any such deficiency. In exercising the rights and remedies under this paragraph, OWNER shall proceed expeditiously, to the extent necessary to complete corrective and remedial action. OWNER may exclude CONTRACTOR from all or part of the site, take possession of all or part of the Work, and suspend CONTRACTOR's services related thereto, take possession of CONTRACTOR's tools, appliances, construction equipment and machinery at the site and incorporate in the Work all materials and equipment stored at the site or for which OWNER has paid CONTRACTOR but which are stored elsewhere. CONTRACTOR shall allow OWNER, OWNER's representatives, agents and employees such access to the site as may be necessary to enable OWNER to exercise the rights and remedies under this paragraph. All direct, indirect and con- sequential costs of OWNER in exercising such rights and remedies will be charged against CONTRACTOR in an amount approved as to reasonableness by PROFESSIONAL, and a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work, and OWNER shall be entitled to an appropriate decrease in the Contract Price, and, if the parties are unable to agree as to the amount thereof, OWNER may make a claim therefor as provided in Article 11. Such direct, indirect and consequential costs will include, but not be limited to, fees and charges of engineers, architects, attorneys and other professionals, all court costs and all costs of repair and replacement of work of others destroyed or damaged by correction, removal or replacement of CONTRACTOR's defective Work. CONTRACTOR shall not be allowed an extension ofthe Contract Time because of any delay in performance of the Work attributable to the exercise by OWNER of OWNER's rights and remedies hereunder. Neglected Work by CONTRACTOR 13.15. If CONTRACTOR neglects to execute the Work in accordance with the Contract Documents, including any requirements of the progress schedule, PROFESSIONAL may direct CONTRACTOR to submit a recovery plan and take specific corrective actions including, but not limited to, employing additional workmen and/or equipment, and working extended hours and additional days, all at no cost to OWNER in order to put the Work back on schedule. If CONTRACTOR fails to correct the deficiency or take appropriate corrective action, OWNER may terminate the contract or CONTRACTOR's right to proceed with that portion of Work and have the GC-48 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 Work done by others. The cost of completion under such procedure shall be charged against CONTRACTOR. A Change Order shall be issued incorporating the necessary revisions in the Contract Documents, including an appropriate reduction in. the Contract Price. If the payments due CONTRACTOR are not sufficient to cover such amount, CONTRACTOR shall pay the difference to OWNER. 13.16.

GC-49 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 ARTICLE 14-PA YMENTS TO CONTRACTOR AND COMPLETION Schedule of Values: 14.1. The schedule of values established as provided in 2.9 will serve as the basis for progress payments and will be incorporated into a form of application for Payment acceptable to Project Manager. Progress payments on account of Unit Price Work will be based on the number of units completed. Application for Progress Payment: 14.2. At least twenty (20) calendar days before the date established for each progress payment (but not more often than once a month), CONTRACTOR shall submitto PROFESSIONAL for review an application for Payment filled out and signed by CONTRACTOR covering the work completed as of the date of the application and accompanied by such supporting documentation as is required by the Contract Documents. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the site or at another location agreed to in writing, the Application for Payment shall also be accompanied by a bill of sale, invoice or other documentation warranting that OWNER has received the materials and equipment free and clear of all liens and evidence that the materials and equipment are covered by appropriate property insurance and other arrangements to protect OWNER's interest therein, all of which will be satisfactory to OWNER. Payment is subject to a ten percent (10%) retain age that will be held until the final payment or acceptance by OWNER. The amount of retain age with respect to progress payments will be as stipulated in the Agreement. CONTRACTOR's Warranty of Title: 14.3. CONTRACTOR warrants and guarantees that title to all Work, materials and equipment covered by any Application for Payment, whether incorporated in the Project or not, will pass to OWNER no later than the time of payment free and clear of all Liens. Review of Applications for Progress Payment: 14.4. PROFESSIONAL will, within ten (10) calendar days after receipt of each Application for Payment, either indicate in writing a recommendation of payment and present the application to OWNER, or return the application to CONTRACTOR indicating in writing PROFESSIONAL's reasons for refusing to recommend payment. In the latter case, CONTRACTOR may make the necessary corrections and resubmit the application. OWNER shall, within thirty-one calendar days of presentation to him of the application for payment with PROFESSIONAL's recommendation of the amount for payment, pay CONTRACTOR amount recommended. GC-50 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 14.5. PROFESSIONAL's recommendation of any payment requested in an Application for Payment will constitute a representation by PROFESSIONAL to OWNER, based on PROF- ESSIONAL's on-site observations of the Work in progress as an experienced and qualified design PROFESSIONAL and on PROFESSIONAL's review of the Application for Payment and the accompanying data and schedules, that the Work has progressed to the point indicated; that, to the best of PROFESSIONAL's knowledge, information and belief, the quality of the Work is in accordance with the Contract Documents subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents, to a final determination of quantities and classifications for Unit Price Work under paragraph 9.10, and to any other qualifications stated in.the recommendation; and that CONTRAC- TOR is entitled to payment of the amount recommended. However, by recommending any such payment, PROFESSIONAL will not thereby be deemed to have represented that exhaustive or continuous on -site inspections have been made to check the quality or the quantity of the Work beyond the responsibilities specifically assigned to PROFESSIONAL in the Contract Documents or that there may not be other ma~ters or issues between the parties that might entitle CONTRACTOR to be paid additionally by OWNER or OWNER to withhold payment to CONTRACT9R. 14.6. PROFESSIONAL's recommendation of final payment will constitute an additional representation by PROFESSIONAL to OWNER that the conditions precedent to CONTRACTOR's being entitled to final payment as set forth in paragraph 14.13 have been fulfilled. 14.7. PROFESSIONAL may refuse to recommend the whole or any part of any payment if, in PROFESSIONAL's opinion, it would be incorrect to make such representations to OWNER. PROFESSIONAL may also refuse to recommend any such payment, or, because of subsequently discovered evidence or the results of subsequent inspections or tests, nullify any such payment previously recommended, to such extent as may be necessary in PROFESSIONAL's opinion to protect OWNER from loss because: 14.7.1. the Work is defective, or completed Work has been damaged requiring correction or replacement. 14.7.2. the Contract Price has been reduced by Written Amendment or Change Order. 14.7.3. OWNER has been required to correct defective Work or complete Work in accordance with paragraph 13.14. or 14.7.4. of PROFESSIONAL's actual knowledge of the occurrence of any of the events enumerated in paragraphs 15.2.1 through 15.2.9 inclusive. OWNER may refuse to make payment of the full amount recommended by PROFESSIONAL because claims have been made against OWNER on account of CONTRACTOR's performance or furnishing of the Work or Liens have been filed in connection with the Work or there are other items entitling GC-51 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 OWNER to a off-set against the amount recommended, but OWNER must give CONTRACTOR immediate written notice (with a copy to PROFESSIONAL) stating the reasons for such action. Substantial Completion: 14.8. When CONTRACTOR considers the entire Work ready for its intended use, CONTRACTOR shall notify OWNER and PROFESSIONAL in writing that the entire Work is substantially complete (except for items specifically listed by CONTRACTOR as incomplete) and request that PROFESSIONAL issue a certificate of Substantial Completion. Within a reasonable time thereafter, OWNER, CONTRACTOR and PROFESSIONAL shall make an inspection of the Work to determine the status of completion. If PROFESSIONAL does not consider the Work substantially complete, PROFESSIONAL will notify CONTRACTOR in writing giving the reasons therefor. If PROFESSIONAL considers the Work substantially complete, PROFESSIONAL will prepare and deliver to OWNER a tentative certificate of Substantial Completion which shall fix the date of Substantial Completion. There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment. OWNER shall have seven days after receipt of the tentative certificate during which to make written objection to PROFESSIONAL as to any provisions of the certificate or attached list. If, after considering such objections, PROFESSIONAL concludes that the Work is not substantially complete, PROFESSIONAL will, within fourteen days after submission of the tentative certificate to OWNER notify CONTRACTOR in writing stating the reasons therefor. If, after consideration of OWNER's, objections, PROFESSIONAL considers the Work substantially complete, PROFESSIONAL will within said fourteen days execute and deliver to OWNER and CONTRACTOR a definitive certificate of Substantial Completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as PROFESSIONAL believes justified after consideration of any objections from OWNER. At the time of delivery of the tentative certificate of Substantial Completion, PROFESSIONAL will deliver to OWNER and CONTRACTOR a written recommendation as to division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, heat, utilities, insurance and warranties. Unless OWNER and CONTRACTOR agree otherwise in writing and so inform PROFESSIONAL prior to PROFESSIONAL's issuing the definitive certificate of Substantial Completion, PROFESSIONAL's aforesaid recommendation will be binding on OWNER and CONTRACTOR until final payment. 14.9. OWNER shall have the right to exclude CONTRACTOR from the Work after the date of Substantial Completion, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. Partial Utilization: 14.10. Use by OWNER at OWNER's option of any substantially completed part of the Work which (i) has specifically been identified in the Contract Documents, or (ii) OWNER, PROFESSIONAL, and CONTRACTOR agree constitutes a separately functioning and usable part of GC-52 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 the Work that can be used by OWNER for its intended purpose without significant interference with CONTRACTOR's performance of the remainder of the Work, may be accomplished prior to Substantial Completion of all the Work subject to the following: 14.10.1. OWNER at any time may request CONTRACTOR in writing to permit OWNER to use any such part of the Work which OWNER believes to be ready for its intended use and substantially complete. If CONTRACTOR agrees, CONTRACTOR will certify to OWNER and PROFESSIONAL that said part of the Work is substantially complete and request PROFESSIONAL to issue a certificate of Substantial Completion for that part of the Work. CONTRACTOR at any time may notify OWNER and PROFESSIONAL in writing that CONTRACTOR considers any such part of the Work ready for its intended use and substantially complete and request PROFESSIONAL to issue a certificate of Substantial Completion for that part of the Work. Within a reasonable time after either such request, OWNER, CONTRACTOR and PROFESSIONAL shall make an inspection of that part of the Work to determine its status of completion. If PROFES SIONAL does not consider that part of the Work to be substantially complete, PROFESSIONAL will notify OWNER and CONTRACTOR, in writing, giving the reasons therefor. If PROFESSIONAL considers that part of the Work to be substantially complete, the provisions of paragraphs 14.8 and 14.9 will apply with respect to certification of Substantial Completion of that part of the Work and the division of responsibility in respect thereof and access thereto. 14.10.2. OWNER may at any time request CONTRACTOR, in writing, to permit OWNER to take over operation of any such part of the Work although it is not substantially complete. A copy of such request will be sent to PROFESSIONAL and, within a reasonable time thereafter, OWNER, CONTRACTOR and PROFESSIONAL shall make an inspection ofthat part ofthe Work to determine its status of completion, and PROFESSIONAL will prepare a list of the items remaining to be completed or corrected thereon before final payment. If CONTRACTOR does not object in writing to OWNER and PROFESSIONAL that such part of the Work is not ready for separate operation by OWNER, PROFESSIONAL will finalize the list of items to be completed or corrected and will deliver such list to OWNER and CONTRACTOR together with a written recommendation as to the division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, utilities, insurance, warranties and guarantees for that part of the Work which will become binding upon OWNER and CONTRACTOR at the time when OWNER takes over such operation (unless they shall have otherwise agreed in writing and so informed PROFESSIONAL). During such operation and prior to Substantial Completion of such part of the Work, OWNER shall allow CONTRACTOR reasonable access to complete or correct items on said list and to complete other related Work. 14.10.3. No occupancy or separate operation of part of the Work will be accomplished prior to compliance with the requirements of paragraph 5.15 in respect of property insurance. 14.10.4. OWNER, may at its discretion, reduce the amount of retain age subject to Beneficial Occupancy. GC-53 I I I I I I I I I I I I I I I I I I I Revision Date August 2001 Final Inspection: 14.11. Upon written notice from CONTRACTOR that the entire Work or an agreed upon portion thereof is complete, PROFESSIONAL will make a final inspection with OWNER and CON- TRACTOR and will notify CONTRACTOR in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. CONTRACTOR shall immediately take such measures as are necessary to remedy such deficiencies. Final Application for Payment: 14.12. After CONTRACTOR has completed all such corrections to the satisfaction of PROFESSIONAL and OWNER and delivered in accordance with the Contract Documents all maintenance and operating instructions, schedules, guarantees, bonds, certificates or other evidence of insurance required by 5.2, certificates of inspection, marked-up record documents and other documents, CONTRACTOR may make application for final payment following the procedure for progress payments.

In lieu of such releases or waivers of liens and as approved by OWNER, CONTRACTOR may furnish receipts or release in full and an affidavit of CONTRACTOR that (i) the releases and receipts include all labor, services, material and equipment for which a lien could be filed, and (ii) all payrolls, material and equipment bills and other indebtedness connected with the Work for which OWNER or OWNER's property might in any way be responsible have been paid or otherwise satisfied. If any Subcontractor or supplier fails to furnish such a release or receipt in full, CONTRACTOR may furnish a bond or other collateral satisfactory to OWNER to indemnify OWNER against any lien. 14.12.1. No application for final payment will be accepted by OWNER until approved as-built documents by CONTRACTOR are accepted and approved by PROFESSIONAL. 14.12.2. Notwithstanding any other provision of these contract documents to the contrary, OWNER and PROFESSIONAL are under no duty or obligation whatsoever to any vendor, materials provider, Subcontractor, laborer or other party to ensure that payments due and owing by CONTRACTOR to any of them are or will be made. Such parties shall rely only on CONTRACTOR's surety bonds for remedy of nonpayment by him.

Final Payment and Acceptance: 14.13. If, on the basis of PROFESSIONAL' s observation of the Work during construction and final inspection and PROFESSIONAL's review of the final Application for Payment and accompanying documentation as required by the Contract Documents, PROFESSIONAL is satisfied that the Work has been completed and CONTRACTOR's other obligations under the Contract Documents have been fulfilled, PROFESSIONAL will, within ten (10) working days after receipt of the final Application for Payment, indicate in writing PROFESSIONAL's recommendation of payment and present the Application to OWNER for payment. At the same time PROFESSIONAL will also give written notice to OWNER and CONTRACTOR that the Work is acceptable subject to the provisions of 14.6. Otherwise, PROFESSIONAL will return the application to CONTRACTOR, indicating in writing the reasons for refusing to recommend final payment, in which case CONTRACTOR shall make the necessary corrections and resubmit the Application. After the presentation to OWNER of the application and accompanying documentation, in appropriate form and substance and with PROFESSIONAL's recommendation and notice of acceptability, the amount recommended by PROFESSIONAL will. become due and will be paid by OWNER to CONTRACTOR. 14.14. If, through no fault of CONTRACTOR, final completion of the Work is significantly delayed and if PROFESSIONAL so confirms, OWNER shall, upon receipt of CONTRACTOR's final Application for Payment and recommendation of PROFESSIONAL and without terminating the Agreement, make payment of the balance due for that portion of the Work fully completed and accepted. If the remaining balance to be held by OWNER for Work not fully completed or corrected is less than the retainage stipulated in the Contract and if bonds have been furnished as required in Article 5, the written consent of the surety to the payment of the balance due for that portion of the Work fully completed and accepted shall be submitted by CONTRACTOR to PROFESSIONAL with the application for such payment.

Drawer 2546 Augusta, Georgia 30903 ATTENTION: Mr. Scott Williams/Mr.Dennis We1ch SUBJECT: Report of Geotechnical Exploration Spirit Creek Force Main Project Richmond County, Georgia Graves Engineering Project No. G-051231 Gentlemen: Graves Engineering Services, Inc. is pleased to submit this report of our exploration services for the proposed project. Our services were provided in accordance with our proposal no. P-04999 which was authorized by Augusta-Richmond County purchase order on January 6, 2005. This report presents a review of the information provided to us, a discussion of the site and subsurface conditions, and our earthwork recommendations. The appendix contains the results of our field and laboratory testing. Project Informadon The project consists of the Spirit Creek Force Main sanitary sewer project in Richmond County, Georgia. The project consists of a force main sewer line that starts from a proposed pump station off of Bennock Mill Road and extends approximately 43,000 linear feet to the north-northwest to the treatment plant located on Highway 56 Loop. We understand that a section of gravity sewer will also extend from the pump station to near the intersection with Highway 56. The route is shown on preliminary plan drawings prepared by and provided to us by Cranston, Robertson & Whitehurst, P.c.. The route had been surveyed by Cranston, Robertson & Whitehurst, P.c. and the centerline of the easements were staked in the field. The route crosses several roads, entrance drives and a Seaboard Coastline Railroad. The route also crosses Butler, Little Spirit and Spirit Creeks. The major road crossings will be bored and jacked such that the pavement sections will remain intact. The force main is generally to be constructed within 8 to 15 feet of existing grades. The proposed pump station is planned to extend to a depth of approximately 40 to 50 feet. The pump station is anticipated to be supported by a mat foundation. Purpose Of Exploration The purpose of this exploration was to obtain specific subsurface data at the site and to provide earthwork recommendations for the proposed project. I I I I I I I I I I I I I I-- I I I I I Augusta-Richmond County clo Cranston, Robertson & Whitehurst, P.c. February 15, 2005 -Page 2- Site Conditions We conducted a site reconnaissance to observe and document surface conditions at the site. Information gathered was used to help us interpret the subsurface data and to detect conditions w~ich could affect our recommendations. The main easement initially runs adjacent or parallel to Spirit Creek ?r to .Little Spirit Creek.. The ro~te has rolling topography with approximately 50 to 60 feet of topographIc relIef. Based on ~e mformatIOn contained on the preliminary Plan and Profile drawings, the existing ground surface elevatIons along the route range from approximately 120 to 180 feet MSL. The route extends through several wetland a.r:eas. Surface water was noted at numerous locations along the route and generally correspond to the locatIons of creeks and associated wetland areas. Most of the site is located just off roadways(Highway 56, 56 Loop and International Boulevard) or railroad easements and these areas are generally cleared of vegetation and were covered with gravel, grassed or had surface soils exposed. Surface soils exposed consist of a sandy organic topsoil or sands of the coastal plain. Intermittent portions of the route extend through areas that are moderately to heavily wooded with hardwoods and pine. Some clearing was performed and an adverse terrain vehicle was utilized to provide access to boring locations. Surface soils exposed consist of a sandy, loamy organic topsoil in wooded areas. Site Geologic Conditions The site is located near the fall line which is the contact area of the Upper Coastal Plain Province and the Piedmont Province. The Coastal Plain soils were deposited during inundation by the ancient oceans and consist of random layers of fine sands and silts interbedded with lenses of clay. The Georgia Piedmont Province is a broad plateau gently sloping from the Blue Ridge Mountains to the Coastal Plain, covering a distance of -illJ--N-Q~imatID one hY.m:lLe..<Lmile~in_th~area._The-5oiLoymurdeILOLthis-area_iS-resictuum-______ formed by in-place weathering of the parents rocks. A typical upland soil profile consists of thin topsoil underlain by a few feet of clayey soils that transition with increasing depth into less clayey, coarser grained silts and sands with varying mica content. Separating the completely weathered soil overburden from the unaltered parent rock is a transition zone of residuum with penetration resistances of more than 100 blows per foot (bpf) which is locally described as partially weathered rock(PWR). Partially weathered rock retains much of the appearance and fabric of the parent rock formations, and may consist of thinly interlayered very hard or dense soil and rock. The weathering processes that formed the overburden soils and partially weathered rock were extremely variable. Differential weathering of the rock mass has resulted in erratically varying subsurface conditions, evidenced by abrupt changes in soil type and consistency in relatively short horizontal and vertical distances. Although no rock outcrops were noted at the surface, depths to rock can be irregular, and isolated boulders, discontinuous rock layers, or rock pinnacles can be present within the overburden transition zones. ~ased on published literature, the site is underlain by Coastal Plain sediments consisting of interbedded SIltS, sands, and clays. These soils overlay residual soils and crystalline rocks of the Piedmont. I I I I I I I I I I I I I I I I I I I Augusta-Richmond County c/o Cranston, Robertson & Whitehurst, P.C. February 15,2005 -Page 3- Subsurface Conditions The subsurface conditions were explored with widely spaced soil test borings drilled according to the procedures presented in the appendix. The bo~ng ~ocations an~ depths. were se~ect.ed by Cranst?n, Robertson & Whitehurst, P.C.. and Graves Engmeenng. The bonng locatIOns are md1cated by statIOn number on the attached boring records. The actual field boring locations were determined by our field crew from staked locations on the route. Boring elevations were obtained by interpolation between contours on the drawing provided to us. The boring elevations shown in the appendix should be considered accurate only to the degree implied by the method used. The subsurface conditions encountered at the boring locations are shown on the Test Boring Records in the Appendix. These Boring Records represent our interpretation of the subsurface conditions based on the field logs, visual examination of field samples by an engineer and tests of the field samples. The lines designating the interface between various strata on the Boring Records represent the approximate interface location. In addition, the transition between strata may be gradual. Water levels shown on the Boring Records represent the conditions only at the time of our exploration. A total of 46 soil test borings were drilled along the route to depths ranging from 10 to 60 feet below the ground surface. The soil test borings revealed a subsurface profile generally consisting of typical coastal plain deposits of interbedded sands, silts and clays. These soils were encountered to the boring termination depths. The surficial layer consisted of loamy and sandy, organic topsoils. The surficial layer was generally encountered to a depths ranging from 3 to 12 inches below the ground surface. The coastal plain soils typically consisted of sands with varying fine grained particle content(SP to SC) interbedded with fine grained clayey silts. The sandy soils were generally loose to dense in consistency , with standard penetration resistance's ranged from 5 to 41 blows per foot with an average of approximately 18. The coastal plain clayey silts were recorded to be generally soft to very hard in consistency with standard penetration resistance's of 2 to 91 blows per foot recorded. Borings B-1, B-2, B-3, B-7 B-45 encountered lenses of a soft, fi~e sandy, clayey si1t("muck" with layers of fiberous organics(peat)) at depths ranging from 12 to 27 feet. Standard penetration resistance1s ranged from 2 to 9 blows per foot. This material was generally encountered very near the adjacent wetland areas. Groundwater Conditions Groundwater was encountered in many of the borings at depths ranging from 2.5 to over 20.0 feet at over 24-hours after drilling. In silty sands the water levels can usually be determined accurately near the time of drilling. In fine grained soils and clayey sands, it may take several days for water levels to stabilize. In addition, fluctuations in the groundwater level can occur due to variations in rainfall, evaporation, construction activity, surface runoff, and other site specific factors. The highest groundwater levels are generally encountered in early spring and the lowest in late summer. The likelihood of groundwater in the near surface soils at some locations can be expected to increase following periods wet weather. This is due to rain water infiltration through the upper sands at those locations. The water can then become "perched" on top of the clayey sands and silts below. I I I I I I I I I I I I I I I I I I I Augusta-Richmond County c/o Cranston, Robertson & Whitehurst, P.c. February 15, 2005 -Page 4- Utility Construction Considerations The construction of the pump station will require excavations on the order of 40 to 50 .fe~t. Based on our review of the project drawings, the force main piping is generally to be cO,nstructed w1~n 8 to 15 f~e~ of existing grades. We have not reviewed the project drawings for the gravIty flow, S~~l1tary sewer p1pmg. However, we understand that it will be installed to depths up to 20 feet. In addItIon, at the road and railroad crossings, we understand that the bore and jack pits will be excavated to depths of 10 to 15 feet. The soils encountered along the route should be amiable to excavation with normal excavation equipment and should not interfere with boring and jacking operations. The deeper cuts are to be extended below the groundwater level, especially near the pump station and the wetlands in the initial sections of the route. Some of these areas are underlain by layers of relatively clean fine to coarse sands. This will likely require wellpoint dewatering as the excavation proceeds(please see the construction water control section of this report). We recommend that the excavations be shored, sloped or benched as required to provide stability and a safe work environment. For the soils encountered, we recommend that cut slopes of 2H: 1 V be utilized. This may require a wider temporary easement at some locations. All excavations should comply with applicable local, state and federal safety regulations including the current OSHA Excavation and Trench Safety Standards. It is our understanding that these regulations are strictly enforced and if they are not closely followed, the owner and contractor could be liable for substantial penalties. Heavy construction equipment and materials removed from the excavations should not be placed within 5 to 10 feet of the top of the excavation. We understand that the bore and jack pits may be shored with the use of driven sheetpiling. Please see the wall and retaining structure section of this report for a more detailed discussion. Since preliminary plans call for the pipe at several locations to be installed below the groundwater table, we recommend that 12 to 18 inches of clean stone be utilized for pipe bedding in wet areas. Compaction of pipe backfill at several locations may be extremely difficult due to the anticipated wet conditions. In addition, wet clayey soils removed from the excavations will require significant drying time prior to reutilization as fill. Therefore, construction planning should assume that significant volumes of select stone bedding and imported initial pipe backfill will be required. Foundation Recommendations We anticipate that a mat foundation will be utilized to support the pump station structure. As stated previously, the foundation is anticipated to vary in depth from 40 feet to 50 feet below existing grades. Therefore, the slab will likely bear in either the firm to very firm sands(SW -SM). Mat foundations bearing in this material can be designed for maximum allowable net bearing pressures of up to 3000 psf, The ~oil parameter used in the analysis and design of mat foundations is the modulus of subgrade reactlOn(Ks). Based on the data obtained in our exploration, we recommend a design modulus of sub grade reaction of 300 kips per cubic foot. The maximum net allowable bearing pressures recommended are based on our previous experience and correlation1s made previously between standard penetration test resistance's and the performance of foundations supported by soils similar to those at this site. We expect total settlements on the order of 1 inch and differential settlements of up to 1/2 inch. I I I I I I I I I I I I I I I I I I I Augusta-Richmond County clo Cranston, Robertson & Whitehurst, P.c. February 15,2005 -Page 5- If possible, foundation concrete should be placed the same day that excavations are dug. If the bearing soils are softened by surface water intrusion or exposure, the softened soils must be removed from the foundation excavation bottom immediately prior to placement of concrete. If the excavation must remain open overnight or if rainfall becomes imminent while the bearing soils are exposed, we recommend that a 2 to 4-inch thick "mud-mat" of "lean" (2000 psi) concrete be placed on the bearing soils before the placement of reinforcing steel. We recommend that the minimum widths for individual column and continuous wall footings be 24 and 16 inches, respectively. The minimum widths are recommended to provide a margin of safety against a local or punching shear failure of the foundation soils. Exterior footings should bear at least 18 inches below final exterior grade. The depths of interior footings should be a minimum of 12 inches below the top of the floor slab. This embedment is necessary to provide adequate confinement of the bearing soils and to achieve the recommended bearing pressure. We recommend that the geotechnical engineer observe the mat area excavations immediately prior to placing concrete. He should compare the soils exposed with those encountered in the soil test borings and document the results. Any significant differences should be brought to the attention of the ownersl representative along with appropriate recommendations. The foundation bearing area should be level or suitably benched. It should also be free of loose soil, ponded water and debris prior to the inspection. Compacted Fill Recommendations We recommend that soils to be used as trench backfills be free of debris and have less than 2% by weight fibrous organic material. They should have a liquid limit less than 50 and a plasticity index less than 20. Before filling operations begin, representative samples of each proposed fill material should be collected. The samples should be tested to determine the maximum dry density, optimum moisture content, natural moisture content, gradation and plasticity of the soil. These tests are needed for quality control during compaction and also to determine if the fill material is acceptable. ' We have conducted laboratory testing and visually inspected soil samples obtained from the site. We expect that most of the sands and silts encountered in the borings are acceptable for use as compacted backfill. The organic soils encountered predominately near the wetland areas are not be acceptable for use as compacted fill due to organic and moisture content. In addition, as stated previously, wet soils(especially clayey soils) removed from the excavations may require significant drying time prior to reutilization as fill. We recommend that all compacted fill be constructed by spreading acceptable soil in loose layers not more than lO inches thick. The fill should be compacted in thin lifts to at least 95 percent of the Standard Proctor maximum dry density (ASTM D-698). The upper 12 inches of fill beneath pavements should be . compacted to at least 100 percent of the Standard Proctor maximum dry density . Th~ moistur~ content of the fill soils should be maintained within +3 and -3 percentage points of the optImum mOIsture content as determined from the Proctor compaction test. This provision may require the contractor to dry the soils during periods of wet weather or wet the soils during the hot summer months. I I I I I I I I I I I I I I I I I I I Augusta-Richmond County clo Cranston, Robertson & Whitehurst, P.C. February 15, 2005 - Page 6- We recommend that the backfill placement and compaction be observed and documented by the geotechnical engineer. Significant deviations, either from specifications or good practice, should be brought to the attention of the owner's representative, along with appropriate recommendations. At least one field density test should be performed for every 100 to 200 linear feet of trench for each lift. Retaining Structures We understand that sheetpiling may be utilized as shoring for the excavations for the bore and jack pits. The sheetpiling will act as a below grade walls when the pits are excavated. These sheetpile walls must be designed to resist soil pressures imposed on them. Walls which are permitted to rotate at the top, such as sheetpiling walls, should be designed to resist "active" lateral earth pressure. Typically, a top rotation of about 1 inch per 10 feet height of wall is sufficient to develop active pressure conditions in soils similar to those encountered at the site. The pump station walls should be designed to resist "at rest" lateral earth pressure since the top of the walls will be braced from movement. To account for the "at rest and active" lateral pressures of retained earth, we recommend that the temporary retaining system design assume that the soils behind the bracing system will apply a triangular stress distribution based on the excavation depth and the following strength parameters for the natural soils at this site: ANGLE of INTERNAL MATERIAL UNIT WEIGHT(PCF) FRICTION(Degrees) COHESION(PSF) Firm SW -SM 115 33 0 Very Loose Sp.SM 95 27 0 Loose SP-SM 100 29 0 Very Loose SM 95 25 0 Loose SM 100 27 0 Firm SM 110 29 0 Very Firm SM 115 30 0 Dense SM 120 32 0 Loose SC 105 28 150 Firm SC 115 30 300 Very Firm SC 120 32 700 V.Soft Clayey ML 85 10 100 Soft Clayey ML 90 11 300 Firm Clayey ML 95 12 800 Stiff Clayey ML 100 13 1500 Very Stiff Clayey ML 105 15 3000 The compacted mass unit weight of the soil'should be used with the above soil parameters to calculate the corresponding earth pressure coefficients and lateral earth pressures, The above values are actual anticipated values and do not contain any safety factors. If dewatering systems are not provided, then the walls should be designed to resist the full hydrostatic head in addition to the lateral earth pressures in areas below the water table. I I I I I I I I I I I I I I I I I I I Augusta-Richmond County clo Cranston, Robertson & Whitehurst, P.C. February 15,2005 -Page 7- The lateral pressures developed by surcharge loads from slopes, heavy construction equip~ent, stored material, stockpiled soils, etc. near the top of the excavation must be added to the lateral SOlI stresses to determine the horizontal loads which must be resisted. In addition, transient loads imposed on the walls by construction equipment during construction should be considered. Excessively heavy equipment (that could impose temporary excessive pressures or long term excessive residual pressures against the constructed walls) should not be allowed within about 5 feet (horizontally) of the walls. Construction Water Control We expect that groundwater control will be required for portions of the alignment due to the presence of shallow groundwater. Since the excavations will extend several feet below the groundwater level, we anticipate that a wellpoint dewatering system will be required at some locations. Wellpoints are small diameter wells that are jetted or driven into the soil(at 3 to 10 foot spacings depending upon soil type) and are placed in straight lines along the area to be drained. They are connected at the top to a horizontal suction pipe called a header and then connected to pump specifically designed for dewatering work. The wellpoints may require staging at various levels as the excavation proceeds to provide the required drawdown of the water table. We recommend that the design of the dewatering system be performed by a specialty contractor that is experienced with similar conditions. We also recommend that pumping continue until the trench is completely backfilled such that backfilling can be completed in as dry a ' condition possible. Basis For Recommendations The recommendations provided are based in part on project information provided to us and they only apply to the specific project and site discussed in this report. If the project information section in this report contains incorrect information or if additional information is available, you should convey the correct or additional information to us and retain us to review our recommendations. We can then modify our recommendations if they are inappropriate for the proposed project. Regardless of the thoroughness of a geotechnical exploration, there is always a possibility that conditions between borings will be different from those at specific boring locations and that conditions will not be as anticipated by the designers or contractors. In addition, the construction process ,may itself alter soil conditions. Therefore, experienced geotechnical personnel should observe and document the construction procedures used and the conditions encountered. Unanticipated conditions and inadequate procedures should be reported to the design team along with timely recommendations to solve the problems created. We recommend that the owner retain Graves Engineering to provide this service based upon our familiarity with the project, the subsurface conditions and the intent of the recommendations. We recommend that this complete report be provided to the various design team members, the contractors and the project owner. Potential contractors should be informed of this report in the "instructions to bidders" section of the bid documents. We wish to remind you that our exploration services include storing the samples collected and making them available for inspection for 60 days. The samples are then discarded unless you request otherwise. I I I I I I I I I I I I I I I I I I I Augusta-Richmond County clo Cranston, Robertson & Whitehurst, P.C.

PART 2 - EXECUTION 2.1 Existing Improvements: A. The Contractor shall maintain in operating condition and protect from damage all existing improvements including utilities, roads, streets, sidewalks, drives, power and telephone lines, gas lines, water lines, sewers, gutters and other drains encountered, and repair to the satisfaction of the utility owner and the Engineer any aerial, surface or subsurface improvements damaged during the course of the work. Where and if shown on the plans, the locations and existence or nonexistence of underground utilities are not guaranteed. The Contractor shall contact the various utility companies to determine and/or verify such information prior to proceeding with the work. He shall make reasonable and satisfactory provisions for the maintenance of traffic on streets, drives, walkways and at street crossings and if necessary to provide temporary walkways and bridges for crossing of the open trench as directed. Work shall not commence within Augusta Right-of-Way until a Right-of-Way Encroachment Permit is obtained from the Public Works Department. 2.2 EXCA V A TION: A. All excavation of every description and of whatever substances encountered shall be performed to the depths indicated on the drawings or as specified herein. Excavation shall be made by the open cut method except as otherwise specified or shown on the drawings. Excavation methods shall comply with codes and ordinances of governing authorities having jurisdiction and to the requirements of OSHA Health and Safety Standards for Excavations, 29 CPR Part 1926, or successor regulations. B. All excavated materials not required for fill or backfill shall be removed and wasted as directed. The banks of shallow trenches shall be kept as nearly vertical as practicable and where required shall be properly sheeted and braced. Except where otherwise indicated, trench bottoms shall be not less than 12 inches wider than the outside diameter of the pipe to be laid therein, and shall be excavated true to line, so that a clear space of not less than 6 inches in width is provided on each side of the pipe. The bottom of trenches shall be accurately graded to provide uniform bearing and support for each section of the pipe on undisturbed soil at every point along its entire length, except for portions of the pipe sections where it is necessary to excavate for bell holes and for the proper sealing of pipe joints. Bell holes shall be dug after the trench bottom has been graded; Bell holes shall be excavated only to an extent sufficient to permit accurate work in the making of the joints and to insure that the pipe, for a maximum of its length will rest upon the prepared bottom of the trench. Depressions for joints other than mechanical shall be made in accordance EXCAVATING, TRENCHING AND BACKFILLING FOR PIPE LINES 02221-1 I I I I I I I I I I I I I I I I I I I with the recommendations of the joint manufacturers for the particular joint used. Excavation for structures and other accessories shall be sufficient to leave at least 12 inches in the clear between their outer surfaces and the embankment or timber which may be used to hold the bank and protect them. Where damage is liable to result from withdrawing sheeting, the sheeting will be ordered to be l,eft in place. Except at locations where excavation of rock from the bottoms of trenches is required, care shall be taken not to excavate below the depths indicated. Where rock excavation is required, the rock shall be excavated to a minimum overdepth of 4 inches below the normal required trench depth. The overdepth rock excavation and all excess trench excavation shall be backfilled with loose, moist earth, thoroughly tamped. Rock is defined as materials which are so hard or cemented that the excavation of such material requires blasting. The excavation shall proceed in a conventional manner with satisfactory effort made to remove hard materials before the Engineer makes a determination of need for blasting. Predrilling and blasting will be allowed, if the Contractor can provide evidence for the Engineer's review that boring logs can and will show that the material can or cannot be excavated. Evidence will be provided for the Engineer's review and approval before predrilling and blasting is undertaken. The excavation and removal. of isolated boulders or rock fragments larger than one cubic yard in volume encountered in materials of common excavation shall be classified as rock excavation. Whenever wet or otherwise unstable soil that is incapable of properly supporting the pipe, as determined by the Engineer or indicated on the drawings,.is encountered in the trench bottom, such soil shall be removed to a depth required for the lengths designated by the Engineer, and the trench backfilled to trench bottom grade, as herein specified, with coarse sand, fine gravel, or other suitable material. Backfill with earth under structures will not be permitted and any unauthorized excess excavation below the levels indicated for the foundation of such structures shall be filled with sand, gravel, or concrete, as directed. 1. GRADING AND STACKING: All grading in the vicinity of trench excavation shall be controlled to prevent surface ground water from flowing into the trenches. Any water accumulated in the trenches shall be removed by pumping or by other approved methods. During excavation, material suitable for backfilling shall be stored in an orderly manner at a distance from the edges of trenches to avoid overloading and prevent slides or cave-ins. Material unsuitable for backfilling, as determined by the Engineer, shall be removed from the job site and disposed of by the Contractor in a manner as approved by the Engineer. 2. SHORING AND SHEETING: All shoring, sheeting, and bracing required to perform and protect the excavation and to safeguard employees and the public shall be performed. The failure of the Engineer to direct the placing of such protection shall not relieve the Contractor of his responsibility for damage resulting from its omission. (a) Whenever sheeting is driven to a depth below the elevation of the top of the pipe, that portion of the sheeting below the elevation of the top of the pipe shall not be disturbed or removed. Sheeting left in place shall be cut off not less than 1 foot below finished grade. No sheeting shall be removed until the excavation is substantially backfilled as hereinafter specified. 3. WATER REMOVAL: Where water is encountered, it shall be prevented from accumulating in excavated areas by pumping, well-pointing and pumping, or by EXCAVATING, TRENCHING AND BACKFILLING FOR PIPE LINES 02221-2 I I I I I I I I I I I I I I I I I I I other means approved by the Engineer as to capacity and effectiveness. Water removed from excavations shall be discharged at points where it will not cause injury to public or private property, or the work completed or in progress. Under no circumstances shall trench bottoms be prepared, pipes laid, or appurtenances installed in water. Water shall not be allowed to rise in unbackfilled excavations after pipe or structures have been placed. 4. BLASTING: Explosives are to used only within legal limitations. Before explosives are used, all necessary permits for this work shall be secured and all precautions taken in the blasting operations to prevent damage to private or public property or to persons. The Contractor shall assume full liability for any damage that may occur during the use of explosives. No blast shall be set off within 50 feet of pipe already laid in the trench. 5. TREE PROTECTION: Care shall be exercised to protect the roots of trees to be left standing. Within the branch spread of the tree, trench shall be opened only when the work can be installed immediately. Injured roots shall be pruned cleanly and backfill placed as soon as possible. 2.3 BACKFILLING: A. Trenches and other excavations shall not be backfilled until all required tests are performed and the work has been approved by the Engineer. The trenches shall be carefully backfilled with the excavated materials approved for backfilling consisting of earth, loam, sandy clay, sand and gravel, soft shale, or other approved materials. No material shall be used for backfilling that contains mulch, other unstable materials, stones, blasted rock, broken concrete or pavement, or other hard materials having any dimension greater than 4 inches; or large clods of earth, debris, frozen earth or earth with an exceptionally high void content. Backfilling within Augusta Right-of-Way shall conform to Georgia Department of Transportation and City of Augusta Specification. ~. B. For backfill up to a level 1 foot over the top of pressure pipelines and 2 feet above the top of gravity pipelines, only selected materials shall be used. Select materials shall be finely divided material free from debris, organic material and stone, and may be suitable job excavated material or shall be provided by the Contractor from other sources. The backfill shall be placed in uniform layers not exceeding 8 inches in depth. Each layer shall be moistened and carefully and uniformly tamped with mechanical tampers or other suitable tools. Each layer shall be placed and tamped under the pipe haunches with care and thoroughness so as to eliminate the possibility of voids or lateral displacement. C. The remainder of the backfill material shall then be placed and compacted above the level specified above. In areas not subject to traffic, the backfill shall be placed in 12 inch layers and each layer moistened and compacted to a density approximating that of the surrounding earth. Under roadways, driveways, paved areas, parking lots, along roadway shoulders and other areas subject to traffic, the backfill shall be placed in 6 inch layers and each layer moistened and compacted to density at least equal to that of the surrounding earth so that traffic can be resumed immediately after backfilling is completed. Any trenches which are improperly backfilled, or where settlement occurs, shall be reopened to the depth required for proper compaction, then refilled and compacted with the surface restored to the required grade compaction. Along all portions of the trenches not located in roadways, the ground EXCAVATING, TRENCHING AND BACKFILLING FOR PIPE LINES 02221-3 I I I I I I I I I I I I I I I I I I I shall be graded to a reasonable uniformity and the mounding over the trenches left in a neat condition satisfactory to the Engineer. D. Sheeting not specified to be ,left in place shall be removed as the backfilling progresses. Sheeting shall be removed in such a manner as to avoid caving of the trench. Voids left by the removal of sheeting and shoring shall be carefully filled and compacted. Where, in the opinion of the Engineer, damage is liable to result from withdrawing sheeting, the sheeting will be ordered to be left in place. 2.4 BORING AND JACKING: A. Where required by the drawings, the pipeline will be installed in a steel casing, placed by boring and jacking. Where boring is required under highways, the materials and workmanship will be in accordance with the standards of the State Highway Department or local authority. Boring and jacking under railroads will be governed by the latest A.R.E.A. standards and those of the railroad involved. The steel casing shall be in accordance with ASTM A252 to the thicknesses shown on the drawings. 2.5 PAVEMENT REMOVAL AND REPLACEMENT: A. Where necessary existing pavements shall be removed and replaced, the applicable standards ofthe State Highway Department or local authority shall govern this work. Joints shall be sawed, unless joints equally uniform in the opinion of the Engineer result from other means. All pavement repairs shall be in accordance with the details in the plans. Where the parent pavement is concrete, the slab surface shall be smoothly finished flush with the surrounding pavements.

The work covered by this section of specifications consists of furnishing all labor, equipment, appliances, and materials, and in performing all operations in connection with the installation of flowable fill work, complete, in strict accordance with this specification and the applicable drawings, and subject to the terms and conditions of the Contract. PART 2 - PRODUCTS 2.1 FLOW ABLE FILL MIX DESIGN: A. The mixes fall into the categories of "very flow able" and "less flowable," which is controlled by the amount of water that is added. The less flowable mix should be used when it is desirable to put traffic back on a roadway quickly (usually 8 to 10 hours) or when being used to backfill pipes which could "float" out of position due to the buoyant effect of the very flowable fill mix. This mix will still self-consolidate around pipes without any "honeycomb" areas. Adding water to flowable fill to obtain the desired plastic characteristics will not compromise the quality of the hardened flowable fill. Less Plowable Mix (Mix 1) Wei2hts Volume Min. 50 Ibs Cement 0.25 Min. 600 lbs.

Anticipated unconfined compressive strength is 80 psi at 28 days and 150 psi at 56 days. For "very flow able" fill (Mix 2), add 10 gallons of water per cubic yard of Mix 1. FLOW ABLE FILL 02520-1 I I I I I I I I I I I I I I I I I I I PART 3 - EXECUTION 3.1 INSTALLATION OF FLOWABLE FILL: A. The trench shall be prepared and the pipe joints placed as normal. There should be at least 6 inches of flow able fill above any utility line. Once the pipe is covered, it will be sufficiently anchored and if directed by the Owner's representative, water may be added to the remaining flowable fill to ease placement without danger of floating the pipe. If it is important to quickly return traffic to the roadway, the flow able fill mixture shall not be altered by the addition of water. B. The flowable fill may be discharged from the ready-mix truck into the space to be filled, or by other methods approved by the Utilities Department representative. The mix may be placed in part depth or full depth as conditions at the site dictate. Formed walls or other bulkheads shall be constructed to withstand the mounded soil rather than wood or metal forms. When backfilling utility lines, flowable fill shall be distributed evenly to prevent movement of the line. C. The material is self-consolidating and there is no need to use vibrators. Finishing can be accomplished with a square shovel if the fill surface is at the bottom of pavement or with a wood float if the surface will be temporarily used as a finished surface. D. Once the flowable fill is in the trench, the self-consolidating material displaces the extra water not needed for maximum density. Provision shall be made for this "bleed water' to run off and away from the surface of the hardening flowable fill (use of vapor barriers suc as plastic sheets is not desired). The material will usually support foot traffic within an hour after the bleeding ends. Typically, full traffic can be allowed on the hardened flowable fill within 8 to 20 hours (depending on site conditions, volume to be backfilled, etc.). Without damage to the fill or any structures below. If it is necessary to return traffic in less than 8 hours, or if there is concern that traffic flow will "rut" the hardening flow able fill, steel plates shall be used to bridge over the hardening flow able fill as directed by the Utilities Department representative. If the filled cavity is too wide to bridge, steel plates shall be placed on top of the hardening flowable fill as soon as it is able to support foot traffic (one hour after bleeding ends), and full traffic can be allowed without damage to the fill or structure below. E. As the extra water is displace from the consolidating flow able fill, there will be an initial subsidence of about one-eighth (1/8) of an inch per vertical foot. Once the flowable fill hardens, there will not be future settlement. The hardened flowable fill can be shaped to grade the next day to allow the patch thickness required. The patch may be applied directly to the cured flowable fill.

During tillage operation, the surface shall be cleared of all roots, cable, wire, or other waste material which might hinder final grading, planting ,or subsequent maintenance operations. Any operations of the Contractor shall be smoothed out before seeding operations are begun. 3.2 FERTILIZATION A. At least two soil samples per acre shall be taken by the Contractor and analyzed to determine the suitability of the particular soil for planting. Fertilization and lime application rates shall be set accordingly. The rates given in the following paragraphs GRASSING BERMUDA 02930-1 I I I I I I I I I I I I I I I I I I I shall be used for bidding purposes and differing quantities will become the basis for an equitable adjustment in the contract price. B. Fertilizer shall be distributed uniformly at a rate of 1500 pounds of commercial 6-12-12 analysis fertilizer per acre, and shall be incorporated into the soil to a depth of approximately three (3) inches by discing, harrowing, or other approved methods. The incorporation of fertilizer may be a part of the tillage operation specified above, or a part of the hydro seeding procedure as described below. C. Immediately following, or simultaneously with, the incorporation of fertilizer, lime shall be distributed at the rate of 3000 pounds per acre and shall be incorporated into the soil to a depth of at least three inches by discing, harrowing, or other acceptable methods. The incorporation of lime along with the fertilizer may form a part of the tillage operation specified above. D.

The time of application shall be limited to the season of June through August. 3.3 PERMANENT SEEDING A. Permanent grass cover will consist of Common Bermuda seeded in accordance with one of the following methods: (1) Between the dates of April 1 and June 1, Hulled Common Bermuda seed shall be applied at a rate of 10 pounds of seed per acre. (2) Between the dates of October 1 and March 1, Unhulled Common Bermuda seed shall be applied at a rate of 10 pounds of seed per acre. (3) If seeding is undertaken between September 15 and February 15, Unhulled Common Bermuda seed shall be applied at a rate of 6 pounds of seed per acre simultaneously with Rye seed at a rate of 28 pounds per acre. B. Seed may be applied by means of a hydro seeder as other means approved by the Engineer. C. Immediately after seeding operations have been completed, the areas shall be compacted by means of a cultipacker, roller wood float, or other approved equipment sufficiently weighted, or compacted by hand methods, to reduce air pockets to a minimum. The complete planted area shall be left with a fIrm, even surface, free from abrupt humps and hollows, and to the established grade. GRASSING BERMUDA 02930-2 I I I I I I I I I I I I I I I I I I I D. All areas planted to a permanent grass shall be uniformly mulched with hay or straw at the rate of 2-1/2 tons per acre, except where hydroseeding is employed using a cellulose mulch mixed with the seed and fertilizer. 3.4 TEMPORARY GRASS Temporary grass shall be used when directed by the Engineer to control erosion where permanent grassing cannot be planted. A. Temporary grass shall be a quick growing species such as rye grass suitable to the area and season. Seeding shall be done in accordance with the permanent grassing requirements above, except that ground preparation shall be the minimum required to provide a seed bed where further grading will be required. Areas that require no further grading shall be prepared as described in "GROUND PREPARATION" above. Lime shall be omitted unless the area will later be planted in permanent grass without further grading, in which case lime shall be applied as described above. Fertilizer shall be applied at the rate of 400 pounds per acre. Nitrogen shall be omitted. B. In March or April of the following year, as soon as weather is suitable, all areas planted in temporary grass which are owned by the City of Augusta shall be thoroughly plowed up and grassed in accordance with the applicable permanent grassing method described above. C. MAINTENANCE: The Contractor shall erect necessary warning signs and barriers, mow grassed areas, and repair or replace grassed areas failing to show a uniform growth of grass or damaged by his operations, and shall otherwise maintain the grass until final acceptance of the contract.

Cool ingredients before mixing, or substitute chip ice for part of required mixing water or use other suitable means to control concrete temperature to prevent rapid drying of newly placed concrete. Shade the fresh concrete and start curing as soon as the surface of the fresh concrete is sufficiently hard to permit curing without damage. 3.4 SURFACE FINISHES A. ACI 301 for repair and finish, unless otherwise specified. Slope floors uniformly to drains where drains are provided. After troweling is completed, apply a liquid chemical sealer-hardener to interior slabs that do not receive floor covering. B. Defects: Repair formed surfaces by removing minor honeycombs, pits greater than 1 square inch surface area or 0.25 inch maximum depth, or otherwise defective areas. Provide edges perpendicular to the surface and patch with non-shrink grout. Patch tie holes and defects when the forms are removed. Concrete with extensive honeycomb (including exposed steel reinforcement, cold joints, entrapped debris, separated aggregate, or other defects) which affect the serviceability or structural strength will be rejected, unless correction of defects is approved. Obtain approval of corrective action prior to repair. The surface of the concrete shall not vary more CAST-IN-PLACE CONCRETE 03300-7 I I I I I I I I I I I I I I I I I I I than the allowable tolerances of ACI 301. Exposed surfaces shall be uniform in appearance and finished to a smooth form finish, unless otherwise specified. C. Floated Finish: Place, consolidate, and immediately strike off concrete to obtain proper contour, grade, and elevation before bleedwater appears. Permit concrete to attain a set sufficient for floating and supporting the weight of the finisher and equipment. If bleedwater is present prior to floating the surface, drag the excess water off or remove by absorption with porous materials. Do not use dry cement to absorb bleedwater. Surface shall be levelto within 1/4 inch in 10 feet where floor drains are not provided. D. Steel Troweled Finish: First, provide a floated finish. When slab has attained a proper set, trowel to a smooth, hard, dense finish. Finished surfaces shall be free of trowel marks, uniform in texture, flat within 0.01 foot (approximately 1/8 inch) in 10 feet. Hand-finish portions of the slab not accessible to power finishing equipment (e.g., edges, corners) to match the remainder of the slab. Power trowel once and finally hand trowel where a finished floor covering (e.g., tile, carpet) is specified. Power trowel twice and finally hand trowel for exposed concrete floors. E. Broomed Finished: Provide for exterior walks, platforms, patios, and ramps, unless otherwise indicated. Provide a floated finish, and then finish with a flexible bristle broom. Permit surface to harden sufficiently to retain the scoring or ridges. Broom transverse to traffic or at right angles to the slope of the slab. F. Pavement Finish: Screed the concrete with a template advanced with a combined longitudinal and crosswise motion. Maintain a slight surplus of concrete ahead of the template. After screeding, float the concrete longitudinally. Use a straight edge to check slope and flatness; correct and refloat as necessary. Obtain final finish by belting. Lay belt flat on the concrete surface and advance with a sawing motion; continue until a uniform but gritty non-slip surface is obtained. Round edges and joints with an edger having a radius of 1/8 inch. 3.5 CURING AND PROTECTION A. ACI 301 - Protect concrete from injurious action by sun, rain, wind, flowing water, frost, mechanical injury, tire marks, and oil stains.
