PATENTS I 9.1 The CONTRACTOR shall pay all applicable royalties and license fees. He shall defend all suits or claims for infringement of any patent rights and save the OWNER harmless from loss on account thereof, except that the OWNER shall be responsible for any such loss when a particular process, design, or the product of a particular manufacturer or manufacturers is specified, however, if the CONTRACTOR has reason to believe that the design, process or product specified is an infringement of a patent, he shall be responsible for such loss unless he promptly gives such information to the ENGINEER.

The CONTRACTOR will employ and maintain on the WORK a qualified supervisor or superintendent who shall have been designated in writing by the CONTRACTOR as the CONTRACTOR'S representative at the site. The supervisor shall have full authority to act on behalf of the CONTRACTOR and all communications given to the supervisor shall be as binding as if given to the CONTRACTOR. The supervisor shall be present on the site at all times as required to perform adequate supervision and coordination of the WORK. I I I 13. CHANGES IN THE WORK I GC - 7 . - I I I 13.1 The OWNER may at any time, as the need arises, order changes within the scope of the WORK without invalidating the Agreement. If such changes increase or decrease the amount due under the CONTRACT DOCUMENTS, or in the time required for performance of the WORK, an equitable adjustment shall be authorized by CHANGE ORDER. I I 13.2 The ENGINEER, also, may at any time, by issuing a FIELD ORDER, make changes in the details of the WORK. The CONTRACTOR shall proceed with the performance of any changes in the WORK so ordered by the ENGINEER unless the CONTRACTOR believes that such FIELD ORDER enti tIes him to a change in CONTRACT PRICE or TIME, or both, in which event he shall give the ENGINEER WRITTEN NOTICE thereof within seven (7) days after the receipt of the ordered change. Thereafter the CONTRACTOR shall document the basis for the change in CONTRACT PRICE or TIME wi thin thirty (30) days. The CONTRACTOR shall not execute such changes pending the receipt of an executed CHANGE ORDER or further instruction from the OWNER. I I 14. CHANGES IN CONTRACT PRICE I 14.1 The CONTRACT PRICE may be changed only by a CHANGE ORDER.

In addition there shall be added an amount to be agreed upon but not to exceed fifteen (15) percent of the actual cost of the WORK to cover the cost of general overhead and profit. I I 15. TIME FOR COMPLETION AND LIQUIDATED DAMAGES I 15.1 The date of beginning and the time for completion of the WORK are essential conditions of the CONTRACT DOCUMENTS and the WORK embraced shall be commenced on a date specified in the NOTICE TO PROCEED. I 15.2 The CONTRACTOR will proceed with the WORK at such rate of progress to insure full completion within the CONTRACT TIME. It is expressly understood and agreed, by and between the CONTRACTOR and the OWNER, that the CONTRACT TIME for the completion of the WORK described herein is a reasonable time, taking into consideration the average climatic and economic conditions and other factors prevailing in the locality of the WORK. I 15.3 If the CONTRACTOR shall fail to complete the WORK within the CONTRACT TIME, or extension of time granted by the OWNER, then the CONTRACTOR will pay to the OWNER the amount for liquidated damages as specified in the BID for each calendar day that the CONTRACTOR shall be in default after the time stipulated in the CONTRACT DOCUMENTS. I I 15.4 The CONTRACTOR shall not be charged with liquidated damages or any excess cost when the delay in completion of the WORK is due to the following, and the CONTRACTOR has promptly given WRITTEN NOTICE of such delay to the OWNER or ENGINEER. I ~ GC - 8 - . - - I .1 I 15.4.1 To any preference, priority or allocation order duly issued by the' OWNER. I 15.4.2 To unforeseeable causes beyond the control and without the fault or negligence of the CONTRACTOR, including but not restricted to, acts of God, or of the public enemy, acts of the OWNER, acts of another CONTRACTOR in the performance of a contract with the OWNER, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, and abnormal and unforeseeable weather; and I 15.4.3 To any delays of SUBCONTRACTORS occasioned by any of the causes specified in paragraphs 15.4.1 and 15.4.2 of this article. I 15.5 No added cost from delay: In the event of a delay in completion occasioned by the causes set out in 15.4.1 thru 15.4.3, the OWNER shall not be required to pay any additional costs resulting from such delay. The extension of time to the CONTRACTOR shall be the exclusive remedy. I 15.6 Non-excusable delay: The factors, with the exception of "Labor Disputes", set out in paragraph 15.4.1 thru 15.4.3 which specify causes for excusable delay in completion of construction shall not constitute a defense for delay in completion caused by the acts or omissions of the CONTRACTOR, its agents or employees. I I 15.7 Change in Contract Time: The CONTACT TIME may only be changed by a CHANGE ORDER or a WRITTEN AMENDMENT. Any claim for an extension or shortening of the CONTRACT TIME shall be based on WRITTEN NOTICE delivered by the party making the claim to the other party and to ENGINEER 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 extent of the claim with supporting data shall be delivered within sixty days after such occurrence (unless ENGINEERS allows an additional period of time to ascertain more accurate data in support of the claim) and shall be accompanied by the claimant's written statement that the adjustment claimed is the entire adjustment to which the claimant has reason to believe it is entitled as a result of the occurrence of said event. All claims for adjustment in the CONTRACT TIME shall be determined by ENGINEER in accordance with paragraph 27.1 if OWNER and CONTRACTOR cannot otherwise agree. No claim for an adjustment in the CONTRACT TIME will be valid if not submitted in accordance with the requirements of this paragraph 15.7. I I I I 16. CORRECTION OF WORK - . 16.1 The CONTRACTOR shall promptly remove from the premises all WORK rejected by the ENGINEER for failure to comply with the CONTRACT DOCUMENTS, whether incorporated in the construction or not, and the CONTRACTOR shall promptly replace and re-execute the WORK in accordance with the CONTRACT DOCUMENTS and without expense to the OWNER and shall bear the expense of making good all WORK of other CONTRACTORS destroyed or damaged by such removal or replacement. . 16.2 All removal and replacement WORK shall be done at the CONTRACTOR'S expense. If the CONTRACTOR does not take action to remove such rejected WORK within ten (10) days after receipt of WRITTEN NOTICE, the OWNER may remove such WORK and store the materials at the expense of the CONTRACTOR. GC - 9 I I 17. SUBSURFACE CONDITIONS I 17.1 The CONTRACTOR shall promptly, and before such conditions are disturbed, except in the event of an emergency, notify the OWNER by WRITTEN NOTICE of: I 17.1.1 Subsurface or latent physical conditions of the site differing materially from those indicated in the CONTRACT DOCUMENTS: or I 17.1.2 Unknown physical conditions at the site, of an unusual nature, differing materially from those ordinarily encountered and generally recognized as inherent in WORK of the character provided for in the CONTRACT DOCUMENTS. I 17.2 The OWNER shall promptly investigate the conditions, and if he finds that such conditions do so materially differ and cause an increase or decrease in the cost of, or in the time required for, performance of the WORK, an equitable adjustment shall be made and the CONTRACT DOCUMENTS shall be modified by a CHANGE ORDER. Any claim of the CONTRACTOR for adjustment hereunder shall not be allowed unless he has given the required WRITTEN NOTICE; provided that the OWNER may, if he determines the facts so justify, consider and adjust any such claims asserted before the date of final payment. I I I 18. SUSPENSION OF WORK, TERMINATION AND DELAY I 18.1 The OWNER may suspend the WORK or any portion thereof for a period of not more than ninety days or such further time as agreed upon by the CONTRACTOR, by WRITTEN NOTICE to the CONTRACTOR and the ENGINEER which notice shall fix the date on which WORK shall be resumed. The CONTRACTOR will resume that WORK on the date so fixed. The CONTRACTOR will be allowed an increase in the CONTRACT PRICE or an extension of the CONTRACT TIME, or both, directly attributable to any suspension. I I 18.2 If the CONTRACTOR is adjudged a bankrupt or insolvent, or if he makes a general assignment for the benefit of his creditors, or if a trustee or receiver is appointed for the CONTRACTOR or for any of his property, or if he files a petition to take advantage of any debtor's act, or to reorganize under the bankruptcy or applicable laws, or if he repeatedly fails to supply sufficient skilled workmen or suitable materials or equipment, or if he repeatedly fails to make prompt payments to SUBCONTRACTORS or for labor, materials or equipment or if he disregards laws, ordinances, rules, regulations or orders of any public body having jurisdiction of the WORK or if he disregards the authority of the ENGINEER, or if he otherwise violates any provision of the CONTRACT DOCUMENTS, then the OWNER may, without prejudice to any other right or remedy and after giving the CONTRACTOR and his surety a minimum of ten {10l days from delivery of a WRITTEN NOTICE terminate the services of the CONTRACTOR and take possession of the PROJECT and of all materials, equipment, tools, construction equipment and machinery thereon owned by the CONTRACTOR, and finish the WORK by whatever method he may deem expedient. In such case the CONTRACTOR shall not be entitled to receive any further payment until the WORK is finished. If the unpaid balance of the CONTRACT PRICE exceeds the direct and indirect costs of completing the PROJECT, including compensation for additional professional services, such excess SHALL BE PAID TO THE CONTRACTOR. If such costs exceed such unpaid balance, the CONTRACTOR will pay the difference to the OWNER. I I I I I I GC - 10 I I I Such costs incurred by the OWNER will be determined by the ENGINEER and incorporated in a CHANGE ORDER. I I 18.3 Where the CONTRACTOR'S services have been so terminated by the OWNER, said termination shall not affect any right of the OWNER against the CONTRACTOR then existing or which may thereafter accrue. Any retention or payment of monies by the OWNER due the CONTRACTOR will not release the CONTRACTOR from compliance with the CONTRACT DOCUMENTS. I 18.4 After ten (10) days from delivery of a WRITTEN NOTICE to the CONTRACTOR and the ENGINEER, the OWNER may, without cause and without prejudice to any other right or remedy, elect to abandon the PROJECT and terminate the CONTRACT. In such case, the CONTRACTOR shall be paid for all WORK executed and any expense sustained plus reasonable profit. I I 18.5 If, through no act or fault of the CONTRACTOR, the WORK is suspended for a period of more than ninety (90) days by the OWNER or under an order of court or other public authority, or the ENGINEER fails to act on any request for payment within thirty (30) days after it is submitted, or the OWNER fails to pay the CONTRACTOR substantially the sum approved by the ENGINEER or awarded by alternate process within thirty (30) days of its approval and presentation, then the CONTRACTOR may, after ten (10) days from delivery of a WRITTEN NOTICE to the OWNER and the ENGINEER, terminate the CONTRACT and recover from the OWNER payment for all WORK executed and all expenses sustained. In addition and in lieu of terminating the CONTRACT, if the ENGINEER has failed to act on a request for payment or if the OWNER has failed to make any payment as aforesaid, the CONTRACTOR may upon ten (10) days WRITTEN NOTICE to the OWNER and the ENGINEER stop the WORK until he has been paid all amounts then due, in which event and upon resumption of the WORK, CHANGE ORDERS shall be issued for adjusting the CONTRACT PRICE or extending the CONTRACT TIME or both to compensate for the costs and delays attributable to the stoppage of the WORK. I I I I 18.6 If the performance of all or any portion of the WORK is suspended, delayed, or interrupted as a result of a failure of the OWNER or ENGINEER to act within the time specified in the CONTRACT DOCUMENTS, or if no time is specified, within a reasonable time, an adjustment in the CONTRACT PRICE or an extension of the CONTRACT TIME, or both, shall be made by CHANGE ORDER to compensate the CONTRACTOR for the costs and delays necessarily caused by the failure of the OWNER or ENGINEER. I I 19. PAYMENTS TO CONTRACTOR I 19.1 At least ten (10) days before each progress payment falls due (but not more often than once a month), the CONTRACTOR will submit to the ENGINEER a partial payment estimate filled out and signed by the CONTRACTOR covering the WORK performed during the period covered by the partial payment estimate and supported by such data as the ENGINEER may reasonably require. If payment is requested on the basis of materials and equipment not incorporated in the WORK but delivered and suitably stored at or near the site, the partial payment estimate shall also be accompanied by such supporting data, satisfactory to the OWNER, as will establish the OWNER'S title to the material and equipment and protect his interest therein, including applicable insurance. The ENGINEER will, within ten (10) days after receipt of each partial payment estimate, either indicate in writing his approval of payment and present the partial payment estimate to the OWNER, or return the partial payment estimate to the CONTRACTOR indicating I I - . - . GC - 11 - I I I in writing his reasons for refusing to approve payment. In the latter case, the CONTRACTOR may make the necessary corrections and resubmit the partial payment estimate. The OWNER will, within ten (10) days of presentation to him of an approved partial payment estimate, pay the CONTRACTOR a progress payment on the basis of the approved partial payment estimate. The OWNER shall retain ten (10) percent of the amount of each payment until final completion and acceptance of all work covered by the CONTRACT DOCUMENTS. The OWNER at any time, however, after fifty (50) percent of the WORK has been completed, if he finds that satisfactory progress is being made, shall reduce retainage to five (5%) percent of the contract amount. When the WORK is substantially complete (operational or beneficial occupancy), the retained amount may be further reduced below five (5) percent to only that amount necessary to assure completion. On completion and acceptance of a part of the WORK on which the price is stated separately in the CONTRACT DOCUMENTS, payment may be made in full, including retained percentages, less authorized deductions. I I I I 19.2 The request for payment may also include an allowance for the cost of such major materials and equipment which are suitably stored either at or near the site. I 19.3 Prior to SUBSTANTIAL COMPLETION, the OWNER, with the approval of the ENGINEER and with the concurrence of the CONTRACTOR, may use any completed or substantially completed portions of the WORK. Such use shall not constitute an acceptance of such portions of the WORK. I 19.4 The OWNER shall have the right to enter the premises for the purpose of doing work not covered by the CONTRACT DOCUMENTS. This provision shall not be construed as relieving the CONTRACTOR of the sole responsibility for the care and protection of the WORK, or the restoration of any damaged WORK except such as may be caused by agents or employees of the OWNER. I I 19.5 Upon completion and acceptance of the WORK, the ENGINEER shall issue a certificate attached to the final payment request that the WORK has been accepted by him under the conditions of the CONTRACT DOCUMENTS. The entire balance found to be due the CONTRACTOR, including the retained percentages, but except such sums as may be lawfully retained by the OWNER, shall be paid to the CONTRACTOR within thirty (30) days of completion and acceptance of the WORK. I I 19.6 The CONTRACTOR will indemnify and save the OWNER or the OWNER'S agents harmless from all claims growing out of the lawful demands of SUBCONTRACTORS, laborers, workmen, mechanics, materialmen, and furnishers of machinery and parts thereof, equipment, tools, and all supplies, incurred in the furtherance of the performance of the WORK. The CONTRACTOR shall, at the OWNER'S request, furnish satisfactory evidence that all obligations of the nature designated above have been paid, discharged, or waived. If the CONTRACTOR fails to do so the OWNER may, after having notified the CONTRACTOR, either pay unpaid bills or withhold from the CONTRACTOR'S unpaid compensation a sum of money deemed reasonably sufficient to pay any and all such lawful claims until satisfactory evidence is furnished that all liabilities have been fully discharged whereupon payment to the CONTRACTOR shall be resumed, in accordance with the terms of the CONTRACT DOCUMENTS, but in no event shall the provisions of this sentence be construed to impose any obligations upon the OWNER to either the CONTRACTOR, his Surety, or any third party. In paying any unpaid bills of the CONTRACTOR, any payment so made by the OWNER shall be considered as a payment made under the CONTRACT I I I I - . GC - 12 - I I DOCUMENTS by the OWNER to the CONTRACTOR and the OWNER shall not be liable to the CONTRACTOR for any such payments made in good faith. I I 19.7 If the OWNER fails to make payment thirty (30) days after approval by the ENGINEER, in addition to other remedies available to the CONTRACTOR, there shall be added to each such payment interest at the maximum legal rate commencing on the first day after said payment is due and continuing until the payment is received by the CONTRACTOR. I 20. ACCEPTANCE OF FINAL PAYMENT AS RELEASE I 20.1 The acceptance by the CONTRACTOR of final payment shall be and shall operate as a release to the OWNER of all claims and all liability to the CONTRACTOR other than claims in stated amounts as may be specifically excepted by the CONTRACTOR for all things done or furnished in connection with this WORK and for every act and neglect of the OWNER and others relating to or arising out of this WORK. Any payment, however, final or otherwise, shall not release the CONTRACTOR or his sureties from any obligations under the CONTRACT DOCUMENTS or the Performance BOND and Payment BONDS. I I 21. INSURANCE I 21.1 The CONTRACTOR shall purchase and maintain such insurance as will protect him from claims set forth below which may arise out of or result from the CONTRACTOR'S execution of the WORK, whether such execution be by himself or by any SUBCONTRACTOR or by anyone directly or indirectly employed by any of them, or by anyone for whose acts any of them may be liable: I 21.1.1 Claims under workmen's compensation, disability benefit and other similar employee benefit acts; I 21 . 1 . 2 Claims sickness or disease, for damages because of or death of his employees: bodily injury, occupational I 21.1.3 Claims for damages because of bodily injury, sickness or disease, or death of any person other than his employees: I 21.1.4 Claims for damages insured by usual personal injury liability coverage which are sustained (1) by any person as a result of an offense directly or indirectly related to the employment of such person by the CONTRACTOR, or (2) by any other person; and I 21.1.5 Claims for damages because of inj ury to or destruction of tangible property, including loss of use resulting therefrom. I 21.2 Certificates of Insurance acceptable to the OWNER shall be filed with the OWNER prior to commencement of the WORK. These Certificates shall contain a provision that coverages afforded under the policies will not be canceled unless at lease fifteen (15) days prior WRITTEN NOTICE has been given to the OWNER.

The rubbing shall be continued sufficiently to remove all form marks and projections, and to produce a smooth dense surface without pits or irregularities. The material which is ground to a paste, in the above process, shall be carefully spread or brushed uniformly over the entire surface and allowed to take a "reset". The final finish shall be obtained by a thorough rubbing with a No. 30 Carborundum stone. This rubbing shall continue until the entire surface is of smooth texture and uniform in color. The surfaces shall be stripped evenly with a brush so as to remove excess paste, and the surface left smooth with only enough paste remaining to obtain a uniform color. I I I I Float Finish: The surface of all concrete slabs shall, unless otherwise hereinafter specified, be given a float finish. The structural slab shall be brought to the established grade by screeding. The surface shall be tested for irregularities with a straightedge. Irregulari ties shall be eliminated and the entire surface finished with a wooden hand float or finishing machine. Finish shall be a true plane within a tolerance of 1/4 inch in 10 feet measured in any direction. I I Broom Finish: Surfaces. of exterior walkways, concrete road pavement, concrete lined ditches, or platforms shall be given a broom finish. A smooth, true and uniform surface is a prerequisite for this finish. When the progress of the set provides the proper consistency, the surface shall be raked with a broom to give parallel transverse lines in the surface, and to give a uniform texture.

I ~: Tests for slump shall be performed at the job site on all concrete immediately prior to placing in accordance with the Test for Slump of Portland Cement Concrete, ASTM C 143. If the slump varies from that of the design mix by more than that permitted by ASTM C 94, the concrete shall be rejected. In no case shall the maximum specified water cement ratio of the approved mix design be exceeded. I Air Content: One test for air content shall be made for each strength test. This test shall be made on a concrete sample that has been removed when consolidation of the concrete in the forms has been completed and shall be in accordance with the Test for Air Content of Freshly Mixed Concrete by the Volumetric Method, ASTM C 173. I I Load Test: If there exists any evidence of faulty workmanship, violations of specifications, or likelihood of concrete having been frozen, load tests may be required in accordance with ACI 318. These tests shall be under the direction of the Engineer. I CONCRETE REPAIRS: I Correction of Deficiencies: The Contractor shall be responsible for correction of concrete work which does not conform to the specified requirements, including strength, honeycomb, spalls, cracks, chips, holes, fins, tolerances and finishes. Where shrinkage cracks in the new hydraulic structures occur away from waterstops, the cracks shall be pressure grouted with epoxy grout to restore the concrete strength and to eliminate leaks.

Particular notice shall be made of the joints to be sure that a watertight joint can be assured. - Joints, Al iqnment and Grade: After the pipe has been installed in the trench, and prior to the placing of any backfill, the joints, alignment, and grade shall be carefully examined and checked for conformance with specified requirements. The pipe shall be observed during backfilling operations and shall be rechecked following the backfilling operations to be sure that the r€quired conditions of the joints, alignment and grade have been maintained. 94162TD5.doc PLANT AND YARD PIPING T5-9 I I I I I I I I I I I I I I I - - Appurtenances: All appurtenances shall be of specified size, shape and materials; the work shall comply with these specifications and if found not so in any respect, it shall be brought to proper condition by cleaning, painting, or if necessary, by rebuilding at the expense of the Contractor. Inteqrity of the Installed Sewer: All pipe lines shall be checked for infiltration and subjected to either an infiltration test, an exfiltration test, or a low-pressure air test to demonstrate the integrity of the installed pipe. The Contractor shall provide, at no additional cost to the Owner, all labor, materials, supervision, equipment and measuring devices necessary to conduct the test. Results of the tests, witnessed by the construction inspector, shall be delivered to the Owner in written form. Meeting the minimum requirement herein specified does not relieve the Contractor of the necessity of making sewers as tight as possible. Low-Pressure Air Test: Only for sections of sewer which are not submerged by groundwater will the air test be applicable. If the pipe to be tested is submerged in groundwater, an infiltration test shall be used. The air test is performed as follows: Flush and clean the sewer line with water prior to testing, thus cleaning out debris and wetting the pipe surface to produce more consistent results. Plug all outlets to resist the test pressure. Give special attention to stoppers and service laterals. Add air until the internal air pressure of the sewer is raised to ~pproximately 4.0 psi gauge. When the pressure has stabilized and is at or lowered -to the starting test pressure of 3.5 psi gauge, commence the test.

Substrates for herbaceous to a depth of 4-6 inches. herbaceous plant survival and the root system. Substrates that are plowing/disking as part of the planting should be deconsolidated I TIME OF PLANTING I It is critical to the plant survival in the constructed wetland that transplanting be performed between April 1 and August 31. Planting prior to mid-March may be allowed if the Contractor can show that substrates/water are not frozen. Plants will suffer less stress if transplanted prior to breaking dormancy. Planting after these times may result in a significant loss due to heat stress when bareroot stock is planted in the hot swnmer months. Emergent plants will need a full growing season to build the root reserves needed to survive winter. Any planting outside of the mid-March to mid-June will require approval by the Engineer. I I SITE PREPARATION I Once the wetland cell is graded, and topsoil replaced, the site should be disked or otherwise prepared for planting root stock. Broadcast the area with barnyard grass to stablize topsoil. High quality wastewater effluent should be released into the cell prior to planting to facilitate soil setting and removal of air pockets. Shallow flooding followed by draining leaving a soupy substrate creates the ideal growth conditions for new plant stocks and facilitates hand or mechanical planting. I PLANTING I The wetland cells will be planted with whole plants, dormant rhizomes and tubers as specified by the Engineer. As the plants are critical to the success of the project, nurseries subcontracted to provide the plants must be inspected and annually certified by their state as meeting the certification criteria. I I Planting may be done by hand or mechanically. Plants will be planted deep enough to prevent propagules from floating out of the planting hole. Stems will be trimmed to avoid toppling after planting and to encourage new stem growth. It is anticipated that the herbaceous plants will develop a good stand within 4-6 weeks. The survivability criteria is a minimum of 80% of each species. Plants not responding within the six week initiation period will require replacement. . iiiiii Proper water depth and careful regulation are the key factors for plant survival during the initial planting. Due to a lack of an extensive root system, initial flooding can cause significant losses. . After planting, the constructed wetland cells should be saturated with water to about 1-3 cm for 4-5 weeks. Water levels must not overtop cut stalks from the original plants or new shoot growth. After the sixth week, if emergent plants show new and vigorous growth, water levels can be slowly and 9416-Guidelines for Planting.doc I I I gradually increased to support erect, upright growth forms. Plants must be established at least six weeks before introduction of wastewater. It is absolutely essential that the stems are above the water surface to avoid drowning new plants. It is also important that water levels not be lowered to the extent to expose the plant roots. I To insure these planting guidelines are followed, a representative of the Engineer will frequently inspect the site. All plant materials entering the site must be approved by the representative of the Engineer prior to planting. Plant materials not meeting the criteria specified or found in an unhealthy condition will be rejected and must be replaced within 48 hours to insure meeting the planting schedule. Substitutions will not be permitted unless approved by the Engineer. I I I I I I I I I I . . I . 9416-Guidelines for Planting.doc . I I SECTION T-10 - GRASSING SCOPE: I The work covered by this section of the specifications consists of furnishing all plant, labor, equipment and materials and performing all operations required to establish a satisfactory cover of grass within all unpaved areas disturbed by construction. All work shall be performed in strict accordance with this section of the specifications and the applicable drawings and subject to the terms and conditions of the Contract. I GENERAL: I The grassing operations shall consist of preparation of the soil, including tillage, liming and fertilizing, seeding or sprigging, mulching, watering, and maintenance and repair of planted areas until a satisfactory grass cover is obtained and the work is finally accepted. I MATERIALS: I Seed: Areas to be grassed shall be seeded with Hulled Bermuda grass seed. All seed for grassing shall be tested and approved by the Georgia Department of Agriculture not more than 6 months prior to the date of sowing and packaged and labeled in accordance with the Georgia Seed Laws and Rules and Regulations in effect on the date of the Invitation for Bids. Seed which has become wet or moldy or otherwise damaged prior to the time of sowing will be rejected. I Agricultural Lime shall be a pulverized limestone having the following certified chemical and physical properties: I Total Carbonates, not less than 85% Passing 10-mesh screen, at least 100% Passing 100-mesh screen, at least 25% I Fertilizer: All fertilizer shall be a dry, free-flowing commercial 10-10-10 fertilizer suitable for application by a fertilizer distributor, grain drill, planting machine or similar standard equipment. The fertilizer shall ___ be certified to meet the requirements of Fertilizer Laws of the State -Of Georgia in effect on the date of the Invitation for Bids. Any fertilizer which becomes caked or otherwise damaged prior to the time of use will be rejected. I I Mulch: Any of the mulch materials, consisting of forest litter, hay, straw, hulls of cotton balls or peanuts, ground corncobs, stalks of corn, cane, potato vines, tobacco or other stems, or peat, which are permitted under Standard Specifications of the State Highway Department of Georgia will be acceptable provided they are properly shredded or ground. Mulch materials which contain seeds of species of weeds or plants which would germinate and be harmful to the proposed planting will not be accepted. Before collection of mulch material is begun or delivery is made, the Contractor shall submit samples for approval. Only approved mulch from approved sources will be accepted. I . - Water for use in connection with the grassing operations will be furnished by the Owner, or obtained from any other approved source. Such water shall be free of excess chlorine, or other chemicals or substances harmful to plant growth. GROUND PREPARATION: Prior to preparing the ground for grassing operations, all weeds, brush and other vegetation in the areas to be planted which has not been removed during clearing and grubbing and grading operations shall be removed from the site. All irregularities in the surface shall be smoothed out and all 94162T10.doc GRASSING TlO-1 I I roots, clay lumps and stone greater than 2 inches in diameter, and other foreign material detrimental to tillage, planting and proper growth and maintenance of the area shall be removed. In all areas where the topsoil has been removed during grading operations, the topsoil which has been stockpiled shall be returned and evenly distributed over these areas. Stockpiled topsoil shall be kept free from subsoil, brush, objectionable weed growth, litter, stones and clay lumps larger than 2 inches in diameter, stumps, roots, and other material that would interfere with planting and maintenance operations. Herbicides used for weed control shall conform to SC-14 . I I LIMING AND FERTILIZING: I After the areas to be seeded have been brought to finished grade, agricultural lime and fertilizer conforming to the requirements of this specification shall be uniformly distributed over the areas, lime at the rate of one ton per acre and fertilizer at the rate of 1000 pounds per acre. In areas where mechanical spreaders cannot be used, the lime and fertilizer may be applied by hand methods. The lime and fertilizer shall not be applied when the wind makes it difficult to obtain satisfactory distribution. I I TILLAGE: I The lime and fertilizer shall be thoroughly and uniformly mixed with the soil to a depth of approximately 3 inches by plowing, discing and harrowing until the. soil is friable and well pulverized. Hand tillage will be required in all areas where mechanical equipment cannot be operated. PLANTING: I Seeding operations shall not be performed prior to April 15 or after September 15, nor unless the soil has the optimum moisture content or more, through a depth of at least 3 inches. I Seeding: Seed conforming to the requirements of this specification shall be uniformly sown by approved mechanical power drawn drills or seeders or, in small areas, by mechanical hand seeders. Hulled Bermuda shall be planted at the rate of 40 pounds per acre. The seeds shall be covered and compacted to a depth of 1/8 to 1/2 inch by means of a cultipacker and an empty traffic roller or another roller weighing less than 3 tons. Broadcast seeding shall not be done when the wind makes it difficult to get satisfactory distribution. I I WATERING: I After the planting has been completed, the moisture content of the soil will be tested. If there is not enough moisture in the soil to insure germination and adequate plant growth, water shall be applied by sprinkling until an adequate moisture content has been reached. In the absence of adequate rainfall during the germination and early growth period, the Contractor will be required to maintain the required adequate moisture content of the soil by periodic sprinkling operations. - - . MULCHING: Mulching of planted areas will not be required but may be employed at the option of the Contractor as an aid in reducing erosion and conserving soil moisture. If employed, the mulch shall conform to the requirements of this specificatlon. The rate of application of the mulch depends on the texture of the mulch. The proper application will allow some sunlight to penetrate and air to circulate, at the same time shading the ground. If desired, immediately after the mulch is spread, the material may be anchored to the soil by a cultipacker, disc harrow, or other suitable equipment. 94162T10.doc GRASSING T10-2 I ESTABLISHMENT AND MAINTENANCE: I The Contractor is responsible for providing a satisfactory stand of living seeded grass in which gaps larger than 12 inches do not occur at the time of acceptance of the project. Any areas which fail to show a uniform stand for any reason whatsoever, shall be replanted according to these specifications and such replanting shall be repeated until acceptance by the Engineer. The Contractor shall properly water, mow and otherwise maintain all planted areas and any damage resulting from erosion, washing or other causes, shall be repaired by fill topsoil, tamping, refertili zing and replanting at no additional expense to the Owner, if such damage occurs prior to acceptance of the project. I I EROSION CONTROL: I In the event completion of grading operations of areas to be planted extends beyond September 15, planting must be postponed until the following spring season. The Contractor will be permitted to seed such areas with Rye grass at his own expense, if he so desires, to control erosion of the graded areas. All mowing and maintenance operations during the fall and winter seasons will be the obligation of the Contractor. Erosion must be controlled by acceptable methods to prevent damage to the Owner's property or to adjacent property owners. I I PAYMENT: I No separate payment will be made for the grassing and other work covered by this section of the specifications. All costs in connection therewith shall be included in the lump sum Base Bid for the completed work.
