Except where otherwise indicated trenches shall be not less than 12 inches wider nor more than 16 inches wider than the outside diameter ofthe pipe to be laid therein, and shall be excavated true to line, so that a clear space not less than 6 inches or more than 8 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 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 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. \M1ere damage is liable to result from withdrawing sheeting, the sheeting will be ordered to be left 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. \M1ere rock excavation is required, the rock shall be excavated to a minimum.over depth of 4 inches below the normal required trench depth. The over depth rock excavation and all excess trench excavation shall be backfilled with loose moist earth, thoroughly tamped. \M1erever wet or othenMse unstable soil that is incapable of properly supporting the pipe, as determined by the Engineer or indicated on the drawings, or 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 the 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. Grading and Stacking: All grading in the vicinity of trench excavations shall be controlled to prevent surface ground water from flowing into the trenches: Any water accumulated in the trenches shall be rwnoved by pumping or by approved methods. During excavation, material suitable for backfilling shall be stored in an orderly manner a minimum distance of one and one-half times the depth of excavation back from the edges of trenches to -6- 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 I I I I I I I I I I I I 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. 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. 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 one foot below finished grade. No sheeting shall be removed until the excavation is substantially backfilled as hereinafter specified. Water Removal: Where water is encountered, it shall be prevented from accumulating in excavated areas by pumping, well-pointing and pumping, or by 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 where the work is 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. Blasting: Explosives are to be 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. Tree Protection: Care shall be exercised to protectthe roots of trees to be left standing. Wthin the branch spread of such trees, all trenching shall be performed with extra care. The 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. BACKFilLING: 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. For backfill up to a level one foot over the top of pressure pipelines and two feet above the top of gravity pipelines, only selected materials shall be used. Select materials shall be finely divided materials 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 6 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. 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 100% maximum dry density, 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 and compaction. Along all portions of the trenches not located in roadways, the ground shall be graded to a reasonable uniformity and the mounding over the trenches left in a neat condition satisfactory to the Engineer. -7- 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. \M1ere in the opinion of the Engineer, damage is liable to result from wthdrawing sheeting, the sheeting will be ordered to be left in place. RESTORATION OF PROPERTY: The Contractor shall carefully restore all property defaced by operations or acts of any of his agents or employees. Such restoration shall include seeding, sodding, and the repair or replacement of driveways, walks, fences, steps, or other facilities in such manner as to meet VoAth the approval of the Engineer and to be at least equal in quality to the original undisturbed work.

SEED BED PREPARATION: Final grades will be established as shown on the plans prior to any seed bed preparation. Washes, low spots and hillocks or windrows will be evened and the bed will be smoothed to facilitate uniform drainage after establishment of the turf before tillage is begun. Graded surfaces will be maintained in a smooth and even concfition until the required cover is established. After the areas to be seeded have been brought to an even and smooth grade, they shall be thoroughly loosened to a depth of at least six (6) inches by plowing, disking. harro\\1ng, or other approved methods until the tillage is acceptable as suitable for seeding. During tillage operations, 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. FERTILIZATION: Fertilization shall be distributed uniformly at a rate of 1,500 pounds of commercial 1 0-1 0-1 0 analysis fertilizer per acre. and shall be incorporated into the soil to a depth of approximately three (3) inches by disking, harro\\1ng, or by other approved methods. The incorporation offertilizer may be apart ofthe tillage operation specified above, or a part of the hydroseeding procedure as described below: Immediately follo\\1ng. or simultaneous \\1th, the incorporation of fertilizer, lime shall be distributed at the rate of 2,000 pounds per acre and shall be incorporated into the soil to a depth of at least three (3) inches by disking, harrowing or other acceptable methods. The incorporation of lime along with the fertilizer may form a part of the tillage operation specified above. Not less than 30 days after completion of seeding, the Contractor shall furnish and apply Nitrate of Soda or Ammonium Sulphate to the planted areas. Nitrate of Soda shall be commercial product, containing not less than 16 percent Nitrogen and Ammonium Sulphate not less than 20 percent Nitrogen. The Nitrogen fertilizer shall be uniformly spread and distributed with approved equipment at the rate that \\111 give not less than 60 pounds of available Nitrogen per acre. Other commercial types of nitrogenous material may be substituted atthe option of the Contractor. The time of application shall be limited to the season of June through August. SEEDING: ~ Permanent grass cover will consist of Common Bermuda seeded in accordance with one of the folloWing methods: Between the dates of April 15 and September 15. Hulled Common Bermuda seed shall be applied at a rate of 20 pounds per acre and Brown-Top Millet seed shall be applied at a rate of 50 pounds of seed per acre. If seeding is undertaken between September 15 and April 15, Unhulled Common Bermuda seed shall be applied at a rate of 40 pounds of seed per acre simultaneously with Ryegrass seed at a rate of 50 pounds per acre. Seed may be applied by means of a Hydroseeder or other means approved by the Engin~er. COMPACTION: 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 hana methods, to reduce air pockets to a minimum.

FLOWABLE FILL MIX DESIGN: The mixes fall into the categories of "very f1owable. 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 Flowable Mix (Mix 1) WEIGHTS VOLUME REFERENCE Min. 501bs. Cement 0.25 ASTM C150, Type I or II Min. 600 Ibs. Fly Ash 4.24 ASTM C618, Class C SSD 25001bs. Sand 15.17 55 gal. 4581bs. Water 7.34 Clean, potable, < 500 ppm chlorides Total Cubic Feet = 27.00 Above values are based on specific gravities - cement 3.15, fly ash 2.27, sand 2.64, and water 1.00. Anticipated unconfined compressive strength is 80 psi at 28 days and 150 psi at 56 days. INSTALLATION OF FLOWABLE FILL: The trench shall be prepared and the pipe joints placed as normal. There should be at least 6 inches of flowable fill above any utility lines. Once the pipe is covered, it will be sufficiently anchored and 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 flowable fill mixture shall not be altered by the addition of water. The f10wable fill may be discharged directly 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. Vllhen backfilling utility lines, flowable fill shall be distributed evenly to prevent any movement of the line. 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. Once 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 such as plastic sheets is not desired). The material will usuall'y support foot traffic within an hour after the bleeding ends. Typically, full traffic can be allowed on the hardened flowable fill -15- within 8 to 20 hours (depending on site conditions, volume to be backfilled, etc.) \Mthout 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 iII-rur the hardening f10wable fill, steel plates shall be used to briqge over the hardening f10wable 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 the structure below. As the extra water is displaced from the consolidating flowable 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 \Mil be no 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. It will be the responsibility of the Contractor to furnish the necessary information to obtain approval of the mix design and to use the necessary construction techniques to assure that the finished material will perform as intended. PAYMENT: All items included in these Specifications shall be paid for at the unit prices shown in the bid schedule. No separate payment \Mil be made for items not shown. . -] 6- 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 I I I I I I I I I I I I 8Ju . ..

The amount of infiltration including MY. branches, and connections shall not exceed 100 gallons per inch diameter per mile of sewer pipe per 24 hours for gravity sewer pipe. The amount of 50 gallons per inch diameter per mile of sewer per 24 hours shall not be exceeded for ductile iron pipe. The Contractor shall be responsible for the satisfactory watertightness of the entire section of sewer. As required, suitable bulkheads shall be installed to permit the test of the sewer. Where the ground water level is less than 1 foot above the top of the pipe at its upper end, or as directed by the Engineer, the sewer shall be subjected to exfiltration testing by plugging the pipe at the lower end and then filling the pipelines and manholes with clean water to a height 4 feet above the top of the sewer at its upper end. The leakage out of the sewer, measured by the volume of the water necessary to maintain meter level in the highest manhole, shall not exceed 200 gallons per inch diameter per 24 hours per mile of sewer for gravity sewer pipe. The amount of 50 gallons per inch diameter per 24 hours per mile of sewer shall not be exceeded for ductile iron pipe. The sewer shall be tested before any connections are made to buildings or to active sewers. The Contractor shall construct such weirs and bulkheads as may be required, shall furnish all water, labor, test plugs, power, pumps, meters, and other equipment necessary for the test to be properly made. The Contractor may use a low pressure air test as an option to the hydraulic infiltrationlexfiltration leakage test for gravity lines provided the Contractor established a correlation between the air test results and the quantity of infiltrationlexfiltration actually being experienced by the line and the allowable air pressure drop shall be that corresponding to the allowable hydraulic leakage specified previously in this section. Such a correlation is to be established according to a procedure satisfactory to the Engineer. The low pressure air test shall be performed in accordance with the applicable sections of the Uni-Bell UNI-B-6- 90, latest version. If the Contractor opts to use the low pressure air test, leakage tests on manholes shall be conducted independently of the lines by using a hydraulic infiltrationlexfiltration test as directed by the Engineer. The allowable infiltration into the mfinhole over a 24 hour period is zero and the allowable exfiltration is also zero when tested by plugging off the manhole and filling it with water four feet above the top of the selNer and measuring the water loss over a 24 hour period. 14.27.3 MEASUREMENT AND PAYMENT Payment will be made at the unit contract prices as shown in the bid schedule under Sanitary Sewer. Measurement of pipelines shall be the actual number of linear feet of pipe installed, complete in place and accepted. No deductions in length will be made for manholes.

Service lines will be paid for at the unit contract price as shown in the bid schedule under Sanitary Sewer, complete as shown on the plans SECTION 14C EXCAVATION & BACKFILLING 14.28 SCOPE This section covers all excavation, trenching and backfilling for pipe lines, complete. 14.29 EXISTING IMPROVEMENTS 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 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 anellor 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 Deparment. 14.30 EXCAVATION 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 generally meet or exceed Occupational Safety and Health Administration (OSHA) construction industry standards. _.~. 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 nor more than 16 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 nor more than 8 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. Sell holes shall be dug after the trench bottom has been graded. Sell holes shall be excavated only to an extent sufficient to permit accurate work in the making of the jo.ints and to insure that the pipe, for a maximum of its length 'Nill rest upon the prepared bottom of the trench. Depressions for joints other than mechanical shall be made in accordance with the 14-26 I I I I I I I I I I . . . . . - . . . - - - . - . I . - . 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. VVhere damage is liable to result from withdrawing sheeting, the sheeting wll be ordered to be left 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. VVhere 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. VVhenever 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. 14.30.1 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 a minimum distance of one and one-half times the depth of the excavation back 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. 14.30.2 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. VVhenever 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. 14.30.3 Water Removal: VVhere water is encountered, it shall be prevented from accumulating in excavated areas by pumping, \Yell-pointing and pumping, or by 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 topublic or private property, or the work completed or in progress. All efforts to prevent sedimentation shall be made. Under no circumstances shall trench bottoms be prepared, pipes laid, or appurtenances installed in water. Water shall not be allo\Ned to rise in unbackfilled excavations after pipe or structures have been placed. 14.30.4 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.

Wthin the branch spread of the tree, trench shall be opened only when the IM>rk can be installed immediately. Injured roots shall be pruned cleanly and backfill placed as soon as possible. 14.31 BACKFILLING Trenches and other excavations shall not be backfilled until all required tests are performed and the IM>rk has been approved by the Engineer. The trenches shall be carefully backfilled 'Nith 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 'Nith an exceptionally high void content Backfilling 'Nithin Augusta right-of-way shall conform to Georgia Department of Transportation and City of Augusta specifications. 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 6 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. 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 wtIich are improperly backfilled, or where settlement occurs, shall be reopened to the depth required for proper compaction, then refilled and compacted 'Nith the surface restored to the required grade compaction. Along all portions of the trenches not located in roadways, the ground shall be graded to a reasonable uniformity and the mounding over the trenches left in a neat condition satisfactory to the Engineer. 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. 14.32 BORING AND JACKING Where required by the drawings, the pipeline will be installed in a steel casing, placed by boring and jacking. Vlthere boring is required under highways, the materials and INOrkmanship will be in accordance with the standards of the Georgia Department of Transportation or local authority. Boring and jacking under railroads 'Nill be governed by the latest AREA standards and those of the railroad involved. The steel casing shall be in accordance with ASTM A252 to the thicknesses shown on the drawings. 14.33 PAVEMENT REMOVAl. AND REPLACEMENT Vllhere necessary existing pavements shall be removed and replaced, the applicable specifications of the Georgia Department of Transportation or local authority shall govern this IM>rk., Joints shall be sawed, unless joints equally uniform in the opinion of Augusta Utilities Department September 2COO Design Standards & Construction Specifications 14-28 I I I I I I I . . . - ..""'"'"j'~-- the Engineer result from other means.
