GENERAL INFORMATION The sample form of Schedule of Values is intended as a guide only. Many projects require a more extensive form with space for numerous items, descriptions of Change Orders, identification of variable quantity adjustments, summary of materials and equipment stored at the site and other information. It is expected that a separate form will be developed by Engineer and Contractor at the time Contractor's Schedule of Values is finalized. Note also that the format for retainage must be changed if the Contract permits (or the law provides), and Contractor elects to deposit securities in lieu of retain age. Refer to Article 14 of the General Conditions for provisions conceming payments to Contractor. B. COMPLETING THE FORM The Schedule of Values, submitted and approved as provided in paragraphs 2.05.8.3 and 2.07 of the General Conditions, should be reproduced as appropriate in the space indicated on the Application for Payment form. Note that the cost of materials and equipment is often listed separately from the cost of installation. Also, note that each Unit Price is deemed to include Contractor's overhead and profit. All Change Orders affecting the Contract Price should be identified and included in the Schedule of Values as required for progress payments. The form is suitable for use in the Final Application for Payment as well as for Progress Payments; however, the required accompanying documentation is usually more extensive for final payment.

GENERAL INFORMATION I This document was developed to provide a uniform format for handling contract changes that affect Funds Available or Contract Times. Changes that have been initiated by a Work Change Directive must be incorporated into a subsequent Change Order if they affect Price or Times. I I Changes that affect Funds Available or Contract Times should be promptly covered by a Change Order. The practice of accumulating Change Orders to reduce the administrative burden may lead to unnecessary disputes. If Milestones have been listed in the Agreement, any effect of a Change Order thereon should be addressed. I For supplemental instructions and minor changes not involving a change in the Contract Price or Contract Times, a Field Order should be used. B. COMPLETING THE CHANGE ORDER FORM I Engineer normally initiates the form, including a description of the changes involved and attachments based upon documents and proposals submitted by Contractor, or requests from Owner, or both. I I Once Engineer has completed and signed the form, all copies should be sent to Owner or Contractor for approval, depending on whether the Change Order is a true order to the Contractor or the formalization of a negotiated agreement for a previously performed change. After approval by one contracting party, all copies should be sent to the other party for approval. Engineer should make distribution of executed copies after approval by both parties. I If a change only applies to price or to times, cross out the part of the tabulation that does not apply. I I I I I - - - .

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 lime, 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, 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. If CONTRACTOR does not correct such defective Work or remove and replace such defective Work within a reasonable time, all as specified in a written notice from PROFESSIONAL, OWNER may have the deficiency corrected. 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 38 - ~ I I I I I I I , I I I I I I I I I I I I Septtmber 19, 2000 or damaged by the correction, removal, or replacement of the defective Work. 39 ~ ~ I I I I I I I I I I I I I I I I I I I - sepce.mber 19, 2000 One Year Correction Period: 13.12.

If CONTRAcrOR 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 CONTRAcrOR. 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, also PROFESSIONAL) prefers to accept it, OWNER may do so. CONTRAcrOR 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 PROFESSIONAls, 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 and OWNER shall be entitled to an appropriate decrease in the Contract Price, and, if the panics 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 recommendationf an appropriate amount will be paid by CONTRAcrOR to OWNER. OWNER May Correct Defective Work: 13.14. If CONTRAcrOR fails within a reasonable time after written notice of PROFESSIONAL to proceed to correct and 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 CONTRAcrOR, 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 CONTRAcrOR from all or part of the site, take possession of all or part of the Work, and suspend CON- TRAcrOR's services related thereto, take possession of CONTRAcrOR'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 CONTRAcrOR but which are stored elsewhere. CONTRAcrOR 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 CONTRAcrOR 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 40 , - I , I I I I I I I I , I I I I - I - . ......

Such direct, indirect and consequential costs will include but not be limited to fees and charges of PROFESSIONAls, 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 of the 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 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, induding 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. Should CONTRACTOR work overtime, weekends or holidays to regain the schedule, all costs to OWNER of associated inspection, construction management and resident PROFESSIONAls shall be identified to CONTRACTOR and the Contract Price reduced by a like amount via Change Order. 41 . - I I I I I , I I I 1 I I I I I I - . September 19. :2000 ARTICLE 14-PAYMENTS 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 submit to 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 equipmef'it 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%) retainage that will be held until the final payment or acceptance by OWNER. The amount of retainage 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 Uens. 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. 14.5. PROFESSIONAL's recommendation of any payment requested in an Application for Payment will constitute a representation by PROFESSIONAL to OWNER, based on PROFESSIONAL's on-site observations of the Work in progress as an experienced and qualified design PROFESSIONAL and on PROF- ESSIONAL'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 42 I I I I I I I I I I I I I I I I I I I I I . . .,. . . - , Sept-ember 19. 2000 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 CONTRACTOR 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 matters or issues between the parties that might entitle CONTRACTOR to be paid additionally by OWNER or OWNER to withhold payment to CONTRACTOR. 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 asset 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 Uens have been filed in connection with the Work or there are other items entitling OWNER to a set-off 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 con- sider 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 43 I - I I I I - I I I I I i I I I I I I , I J ~ Septem.ber 19. 2000 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 wilting and so inform PROFESSIONAL prior to PROFESSIONAL's issuing the definitive certificate of Substantial Completion, PROFESSIONAL's afore- said 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 OWN ER 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 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 inspec- tion of that part of the Work to determine its status of completion. If PROFESSIONAL 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 o(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 44 ~ I I I I I , I I I I , I I I I I I I 1 - September 19. 2000 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 of that part of the Work to determine its status of completion and 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. 14.1004. OWNER, may at its discretion, reduce the amount of retainage subject to Beneficial Occupancy. Final Inspection: 14.11. Upon written notice from CONTRACTOR that the entire Work or an agreed portion thereof is complete, PROFESSIONAL will make a final inspection with OWNER and CONTRACTOR 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 deficiendes. 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.

General Indemnity: CONTRACTOR shall indemnify OWNER and PROFESSIONAL for any damages sustained including lost profits resulting from CONTRACTOR's failure or refusal to perform the work required by these contract documents. 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.

APPLICATION FOR PAYMENT INSTRUCTIONS A. GENERAL INFORMATION The sample form of Schedule of Values is intended as a guide only. Many projects require a more extensive form with space for numerous items, descriptions of Change Orders, identification of variable quantity adjustments, summary of materials and equipment stored at the site and other information. It is expected that a separate form will be developed by Engineer and Contractor at the time Contractor's Schedule of Values is finalized. Note also that the format for retainage must be changed if the Contract permits (or the law provides), and Contractor elects to deposit securities in lieu of retainage. Refer to Article 14 of the General Conditions for provisions concerning payments to Contractor. B. COMPLETING THE FORM The Schedule of Values, submitted and approved as provided in paragraphs 2.05.B.3 and 2.07 of the General Conditions, should be reproduced as appropriate in the space indicated on the Application for Payment form. Note that the cost of materials and equipment is often listed-separately from the cost of installation. Also, note that each Unit Price is deemed to include Contractor's overhead and profit. All Change Orders affecting the Contract Price should be identified and included in the Schedule of Values as required for progress payments. The form is suitable for use in the Final Application for Payment as well as for Progress Payments; however, the required accompanying documentation is usually more extensive for final payment. All accompanying documentation should be identified in the space provided on the form. C. LEGAL REVIEW All accompanying documentation of a legal nature, such as Lien waivers, should be reviewed by an attorney, and Engineer should so advise Owner. aa f-dI.l ~ ~~o o~~ ~~i ~ Y7 ~~ e<j ~o ~ <~ ~U') ~ Y7 ~ , ~ u 0 ~ ~ ~ I >-a ~~ I <~ go u I ~U')~ S~5 a~o I ~>~ U~ U')o ~ I a >- ~~ I ~ ~ I ~~ ~ gjO' I ~~ , 5~ I I I I i ~ I ~ ~ ~ t: . . . . . . . .

GENERAL INFORMATION This document was developed to provide a uniform format for handling contract changes that affect Contract Price or Contract Times. Changes that have been initiated by a Work Change Directive must be incorporated into a subsequent Change Order if they affect Price or Times. Changes that affect Contract Price or Contract Times should be promptly covered by a Change Order. The practice of accumulating Change Orders to reduce the administrative burden may lead to unnecessary disputes. If Milestones have been listed in the Agreement, any effect of a Change Order thereon should be addressed. For supplemental instructions and minor changes not involving a change in the Contract Price or Contract Times, a Field Order should be used. B. COMPLETING THE CHANGE ORDER FORM Engineer normally initiates the form, including a description of the changes involved and. attachments based upon documents and proposals submitted by Contractor, or requests from Owner, or both. Once Engineer has completed and signed the form, all copies should be sent to Owner or Contractor for approval, depending on whether the Change Order is a true order to the Contractor or the formalization of a negotiated agreement for a previously performed change. After approval by one contracting party, all copies should be sent to the other party for approval. Engineer should make distribution of executed copies after approval by both parties. If a change only applies to price or to times, cross out the part of the tabulation that does not apply. , , I I I I I I I I I I I I ~ I - - - -, I CERTIFICATE OF SUBSTANTIAL COMPLETION DATE OF ISSUANCE OWNER CONTRACTOR Contract: Project: OWNER's Contract No. ENGINEER's Project No. This Certificate of Substantial Completion applies to all Work under the Contract Documents or to the following specified parts thereof: To OWNER And To CONTRACTOR The Work to which this Certificate applies has been inspected by authorized representatives of OWNER, CONTRACTOR and ENGINEER, and that Work is hereby declared to be substantially complete in accordance with the Contract Documents on DATE OF SUBSTANTIAL COMPLETION A tentative list of items to be completed or corrected is attached hereto.

Standards: Provide all materials and promptly take all actions necessary to achieve effective erosion and sedimentation control in accordance with the Georgia Erosion and Sedimentation Act of 1975 as amended in 1989, local enforcing agency guidelines and these Specifications. 3.02 TEl\1PORARY EROSION AND SEDIl\1ENTATION CONTROL A. Temporary erosion and sedimentation control procedures should be initially directed toward preventing silt and sediment from entering the creeks. The preferred method is to provide an undisturbed natural buffer, extending a minimal 25 feet from the top of the bank, to fIlter the runoff. Should this buffer prove infeasible due to construction activities being too close to the creek, or if the amount of sediment overwhelms the buffer, the Contractor shall place silt fences to fIlter the runoff and, if necessary, place permanent Rip Rap to stabilize the creek banks. When excavation activities disturb the previously stated preventative measures or if they are not maintained, or whenever the construction activities cross the creeks, the check dams shall be installed downstream and within 200 feet of the affected area. B. Silt dams, silt fences, traps, barriers, check dams, appurtenances and other temporary measures and devices shall be installed as approved and shall be maintained until no longer needed, and shall then be removed. Deteriorated hay bales and dislodged fIlter stone shall be replaced with new materials. Detention ponds, if constructed, shall be maintained in a condition ensuring that unfiltered water will not leave the pond. C. Where permanent grassing is not appropriate, and where the Contractor's temporary erosion and sedimentation control practices are inadequate, the Engineer may direct the Contractor to provide temporary vegetative cover with fast growing seedlings. Such temporary vegetative cover shall be provided by the Contractor in compliance with the Manual for Erosion and Sedimentation Control in Georgia, specifically in the selection of species, planting dates and application rates for seedlings, fertilizer and mulching, with the exception that kudzu shall not be permitted. D. All erosion and sedimentation control devices, including check dams, shall be inspected by the Contractor at least weekly and after each rainfall occurrence and cleaned out and repaired by the Contractor as necessary. E. Temporary erosion and sedimentation control devices shall be installed and maintained from the initial land disturbance activity until the satisfactory completion Spirit Creek Sanitary Sewer Rehabilitation City of Augusta 03/13/02 .

Permanent stabilization of steep slopes and creeks shall be performed in accordance with Item 3.05 of this section. B. Permanent erosion control measures shall be implemented as soon as practical after the completion of pipe installation or land disturbance for each segment of the Project. In no event shall implementation be postponed when no further construction activities will impact that portion or segment of the Project. Partial payment requests may be withheld for those portions of the Project not complying with this requirement. 3.04 GRASSING A. General: 1. All references to grassing, unless noted otherwise, shall relate to establishing permanent vegetative cover as specified herein for seeding, fertilizing, mulching, etc. 2. When final grade has been established, all bare soil, unless otherwise required by the Contract Documents, shall be seeded, fertilized and mulched in an effort to restore to a protected condition. Critical areas shall be sodded as approved or directed by the Engineer. 3. Specified permanent grassing shall be performed at the first appropriate season following establishment of final grading in each section of the site. 4. Permanent grassing shall be of a perennial species. B. Replant grass removed or damaged in residential areas using the same variety of grass and at the first appropriate season. Where sod is removed or damaged, replant such areas using sod of the same species of grass at the first appropriate season. Outside of residential or landscaped areas, grass the entire area disturbed by the Spirit Creek Sanitary Sewer Rehabilitation City of Augusta 03/13/02 , , I I I I I I I I I I I I I I I I I , I I I 02125-7 Erosion and Sediment Control work on completion of work in any area. In all areas, promptly establish successful stands of grass. C. Grassing activities shall comply with the Manual for Erosion and Sediment Control in Georgia, specifically for the selection of species, with the exception that kudzu shall not be permitted, planting dates and application rates for seeding, fertilizer and mulching. Where permanent vegetative cover (grassing) cannot be immediately established (due to season or other circumstances), the Contractor shall provide temporary vegetative cover. The Contractor must return to the site (at the appropriate season) to install permanent vegetation in areas that have received temporary vegetative cover. D. information. See Specifications SectiOIll 02270 - Vegetative Erosion Control, for related 3.05 PLACING OF RIP RAP A. Rip rap shall be placed where ordered by the Engineer, at all points where banks of streams or drainage ditches are disturbed by excavation, or at all points where natural vegetation is removed from banks of the streams or drainage ditches. Carefully compact backfill and place rip rap to prevent subsequent settlement and erosion. This requirement applies equally to construction along side a stream or drainage ditches as well as crossing a stream or drainage ditch. B. When trenching across a creek, place Rip Rap a distance of 10 feet upstream and 10 feet downstream from the top of the trench excavation. Place Rip Rap across creek bottom, across creek banks and extend Rip Rap placement 5 feet beyond the top of each creek bank. C. Preparation of Fou.ndations: The ground surface upon which the rip rap is to be placed shall be brought in reasonably close conformity to the correct lines and grades before placement is commenced. Where fIlling of depressions is required, the new material shall be compacted with hand or mechanical tampers. Unless at creek banks or otherwise shown or specified, Rip Rap shall begin in a toe ditch constructed in original ground around the toe of the fill or the cut slope. The toe ditch shall be 2 feet deep in original ground and the side next to the fill or cut shall have that same slope. After the Rip Rap is placed, the toe ditch shall be backfilled and the excess dirt spread neatly within the construction easement. D. Placement of Filter Fabric: The surface to receive fabric shall be prepared to a relatively smooth condition free from obstructions, depressions and debris.

A higher concentration (%) of acrylic base material may be used to increase strength or offset dilution during injection. 2) The ability to tolerate some dilution and react in moving water during injection. 3) A viscosity of approximately 2 centipoise, which can be increased with additives. 4) A constant viscosity during the reaction period. 5) A controllable reaction time from 5 seconds to 6 hours. 6) A reaction (curing) which produces a homogeneous, chemically stable, non-biodegradable, flexible gel. 7) The ability to increase mix viscosity, density and gel strength by the use of additives. c. Urethane Base Gel Chemical Sealing Material: 1) One (1) part urethane prepolymer thoroughly mixed with between 5 and 11 parts of water by weight. The recommended mix ratio is 1 part urethane prepolymer to 8 parts of water (11 % prepolymer). 2) A liquid prepo1ymer having a solids content of 77% to 83%, specific gravity of 1.04 (8. 65 pounds per gallon), and a flash point of 20oF. Spirit Creek Sanitary Sewer Rehabilitation City of Augusta 03/14/02 ~ ~ I I I I I I , , I , , I , I I I I , ~ I I ~ 02491-9 Rehabilitation of Sanitary Sewer Manholes 3) A liquid prepo1ymer having a viscosity of 300 to 1,000 centipoise at 700F that can be pumped through 500 feet of 1I2-inch hose with a 1,000-psi head at a flow rate of 1 ounce per second. 4) The water used to react the prepolymer should have a pH of 5 to 9. 5) Gel times shall be as short as practical and as short as 2 minutes for polyurethane grouts, in accordance with the manufacturer's recommendations. Control of gel times is a critical aspect of successful chemical grouting. Higher water ratios give longer cure times. 6) A relatively rapid viscosity mcrease of the prepolymer/water mix in the fIrst minute.

This time _period is referred to as the cure time, induction period, or gel time. The low viscosity is advantageous for penetration but makes the grouts susceptible to dilution during the reaction period. 9) Urethane gel grout undergoes a viscosity increase during the time between mixing the base material water and the formation of a gel. This time period is cure time or gel time. The increasing viscosity limits penetration by dilution, particularly by groundwater. PART 2B - MANHOLE LINING 2B.Ol GENERAL A.

The objective of preconditioning and cleaning is to maximize sewer and manhole service efficiency and effectiveness. Preconditioning and cleaning involves removal of silt defined as any and all solid or semi-solid materials, including fine and granular material, such as sand, grit, gravel, and rock as well as debris, grease, oil, sludge, slime, or any other loose material or encrustation lodged in the manhole or sewer. Preconditioning and cleaning also involves removal of invading roots, corroded concrete, corroded manhote rungs, corroded ladders, intruding laterals and any other extraneous debris. Two levels of performance concerning preconditioning and cleaning of manholes and sewers shall be adhered to in this contract, as directed: 1. Preconditioning and cleaning as a general level of service; this requires that manholes and sewers shall be considered preconditioned and cleaned if: a. Silt is removed and disposed of to not more than a nominal depth of 10% of the through flow channel in manholes, or sewer between manholes, where the through flow channel or sewer has an equivalent diameter up to and including 24 inches, and b. Silt is removed and disposed of to not more than a nominal depth of 5% of the through flow channel in manholes or sewer between manholes, where the through flow channel or sewer has an equivalent diameter greater than 24 inches. c. No surface or appurtenance in manholes including walls, cones, slabs (both intermediate and roof slabs), rungs and benches and drop shafts shall have any remnant of silt, coating, loose bricks, unsound concrete or mortar or loose material. d. All roots, corroded concrete, corroded rungs, corroded ladders and intruding laterals are treated or reduced and cut flush with the interior surface of manholes and sewers, removed and disposed of. Fulfillment of these requirements (e.g., depth of silt or cleanliness of surface) is to be determined by internal manhole and sewer condition Spirit Creek Sanitary Sewer Rehabilitation City of Augusta 03/12/02 , , I I I , I I I , I I I , I I \ I i I I I , I I I I I I I I ~ I I 02511-2 Preconditioning and Cleaning Manholes and Sewers surveyor inspection of each manhole and sewer length preconditioned or cleaned as directed. 2. Preconditioning and cleaning prior to rehabilitation and repair; which requires that manholes and sewers shall be considered preconditioned and cleaned if, in addition to the requirements of 1.01.A.l above, all silt has been removed from a minimum of 95% of the through flow channel and sewer cross section. In the case of manholes, all surfaces shall be free of cleaning agents and their reactant products. Fulfillment of these requirements is to be established by internal manhole and sewer condition surveyor inspection of each manhole and sewer length preconditioned or cleansed as directed. B. The Contractor shall precondition and clean the manholes and sewers listed and/or shown on the Contract Drawings or specified herein so as to remove all silt, debris, roots, corroded concrete, corroded rungs and ladders, intruding laterals etc and dispose of the material at an approved site. C. The manholes and lengths of sewers listed in the Bid Form provide the Contractor with a basis for estimating the lengths and quantities of silt to be removed and preconditioning to be performed. The Contractor must estimate quantities and types of silt to be removed and the extent of preconditioning work required from his own field reconnaissance of the manholes and sewers as well as inspection and evaluation of any available relevant City record information. Interpretation of any field observations and review of City records is the responsibility of the Contractor. D. During preconditioning and cleaning work, and all other associated Contractor operations, sewer services shall be maintained at all times. This requirement may be relaxed only with the written approval of the Engineer. E. The manholes and sewers to be preconditioned and cleaned convey sanitary sewage or combined sewage. In many instances, such sewers are subject to high flows, either continuously or in a periodically varying cycle, due .to rainfall, infIltration, and/or pumping operations. The Contractor shall include in his bid provisions for dealing with such variations, and where necessary, schedule his work to accommodate such variation in flows. F.

Steps 2 through 5 shall be repeated at the Contractor's own expense until the selected day is 85% accurate on the initial audi.1.. 7. The occurrence of five randomly selected days not achieving 85% accuracy on initial subcontractor review will constitute cause for dismissal. 8. If the Contractor successfully meets the 85% accuracy requirement for the initial.randomly selected day for 2 consecutive months (Step 2 above), the Contractor may subsequently audit 1 day every other month. The Contractor may continue auditing 1 day every other month until the initial randomly selected day does not meet 85% accuracy, at which time it must resume auditing 1 day every month. 3.11 COLLAPSED SEWERS/DEFECTIVE MANHOLES A. Any sewer found with greater than 10% deformation (i.e., collapsed or near to collapse), must be reported to the designated Engineer immediately for remedial action. In the event of emergency, phone (XXX)XXX-XXXX. B. Any manhole found broken, cracked, with missing covers or surcharged, must be reported to the designated Engineer immediately for remedial action. In the event of emergency, phone (XXX)XXX-XXXX. C. Any sewer found where the existing conditions pose a threat of personal injury to the public, such as a collapsed sewer with attendant depression to roadway, must be protected by the Contractor until the Engineer arrives at the jobsite. In the event of emergency, phone (XXX)XXX-XXXX. D. Any manhole found where the existing conditions pose a threat of personal injury to the public, such as broken, cracked or missing covers or covers found in traveled portions of any sidewalk or roadway, must be protected by the Contractor until the Engineer arrives at the jobsite.

Furnish all products and perform all labor necessary to fulfill the requirements of these Specifications. 1.02 APPLICABLE REHABILITATION :METHODS A. Pipe and fittings furnished for this work must comply with the requirements of Section 02730 - Sewer and Accessories, of the Contract Documents. Replacement pipe shall be the same size as the existing pipe and shall be laid on a uniform grade between the ends of existing pipe which remain in place, unless otherwise indicated in writing to be acceptable to the City. It is the Contractor's complete responsibility to set controls as necessary to attain true line and grade for the replacement pipe. B. Point repairs are made at specific locations and involve relatively short lengths of sewer. Isolation of affected reaches of sewer, by plugging and/or bypass pumping if required, shall be performed in accordance with Section 02750 - Wastewater Flow Control, of the Contract Documents. The cost for such plugging and/or bypass pumping shall be included in the unit bid price for point repairs. C. Locations where point repairs are identified on the Drawings are based on previously performed smoke tests and/or television inspection. It is understood that the exact location of pipe leaks and failures cannot always be determined before the pipe is exposed because the smoke injected into the existing pipe to detect their presence can migrate through passages in the earth, overburden, and may not emerge directly over the leak or failure. Precise location of required point repairs shown on the Drawings is the responsibility of the Contractor, and shall be included in the unit bid price. D. Mter the designated repairs have been made, the Contractor will test them as described in this section of these Specifications. The costs of testing will be borne by the Contractor. If a repaired joint or section should prove to be defective, the Contractor shall re-perform the work at no additional cost to the City, and shall also Spirit Creek Sanitary Sewer Rehabilitation City of Augusta 03/13/02 , , I I , I J I I I I , I , I I \ I I I 02757-2 Sanitary Sewer Point Repair be responsible for the costs of any re-testing required by the City to document the success of the re-work.

Repair and patch defective areas with cement mortar immediately after removal of forms, but only when acceptable to Engineer. 2. Cut out honeycomb, rock pockets, voids over 1/8 inch in any dimension and holes left by tie rods and bolts, down to solid concrete but, in no case to a depth of less than one inch. Make edges of cuts perpendiCular to the concrete surface. Thoroughly clean, dampen with water and brush-coat the area to be patched with neat cement grout. Proprietary patching compounds may be used when acceptable to Engineer. 3. For exposed-to-view surfaces, blend white Portland cement and standard Portland cement so that, when dry, patching mortar will match color of surrounding surface. Provide test areas at inconspicuous location to verify mixture and color match before proceeding with patching. Compact mortar in place and strike-off slightly higher than surrounding surface. B. Repair of Formed Surfaces: 1. Remove and replace concrete having defective surfaces if defects cannot be repaired to satisfaction of Engineer. Surface defects, as such, include color and texture irregularities, cracks, spalls, air bubbles, honeycomb, rock pockets and holes left by tie rods and bolts; fins and other projections on surface; and stains and other discolorations that cannot be removed by cleaning. Flush out form tie holes, fIll with dry pack mortar, or precast cement core plugs secured in place with bonding agent.

Repair concealed formed surfaces, where possible, that contain defects that adversely affect the durability of the concrete. If defects cannot be repaired, remove and replace the concrete. c. Repair of Unformed Surfaces: 1. Test unformed surfaces, such as monolithic slabs, for smoothness and to verify surface plane to toletances specified for each surface and finish. Correct low and high areas as herein specified. Test unformed surfaces sloped to drain for trueness of slope, in addition to smoothness, using a template having required slope. 2. Repair finished unformed surfaces that contain defects that adversely affect durability of concrete. Surface defects, as such, include crazing, cracks in excess of O.Ol-inch wide or which penetrate to reinforcement or completely through non-reinforced sections regardless of width, spalling, pop-outs, honeycomb, rock pockets, and other objectionable conditions. 3. Correct high areas in unformed surfaces by grinding, after concrete has cured at least 14 days. 4. Correct low areas in unformed surfaces during, or immediately after completion of surface finishing operations by cutting out low areas and replacing with fresh concrete. Finish repaired areas to blend into adjacent concrete. Proprietary patching compounds may be used when acceptable to the Engineer. . . 5. Repair defective areas, except random cracks and single holes not exceeding I-inch diameter, by cutting out and replacing with fresh concrete. Remove defective areas to sound concrete with clean, square cuts and expose reinforcing steel with at least 3/4-inch clearance all around. Dampen concrete surfaces in contact with patching concrete, and brush with a neat cement grout coating or concrete bonding agent. Place patching concrete before grout takes its initial set. Mix patching concrete of same materials to provide concrete of the same type or class as original concrete. Place, compact and finish to blend with adjacent finished concrete. Cure in the same manner as adjacent concrete. 6. Repair isolated random cracks and single holes not over I-inch in diameter by dry-pack method. Groove top of cracks and cutout holes to sound concrete and clean of dust, dirt and loose particles. Dampen cleaned concrete surfaces and brush with neat cement grout coating or concrete bonding agent. Place dry-pack before cement grout takes its initial set. Mix dry-pack, consisting of one part Portland cement to 2-112 parts fine aggregate passing a No. 16 mesh sieve, using only enough water as required for handling and placing. Compact dry-pack mixture in place and ,. Spirit Creek Sanitary Sewer Rehabilitation City of Augusta 03/12/02 I I I I I I I I I I . I I I 03010-22 Concrete Work finish to match adjacent concrete. Keep patched areas continuously moist for not less than 72 hours. 7. Repair methods not specified above may be used, subject to acceptance of Engineer. 8. Agreement by the Engineer to permit repair or patching of concrete does not waive the Engineer's authority to require complete removal and replacement of defective concrete pours should the patch .not prove satisfactory to the Engineer,' due either to deficiency in strength, function or appearance.
