In the event the required accuracy of alignment and grade is not adhered to,the Engineer will prohibit the use of laser beams. 07120.4 PREPARATION OF PIPE FOUNDATION The pipe foundation shall be prepared to be uniformly firm and shall be true to the lines and grades as shown on the plans. The preparation of the pipe bedding shall be in accordance with the typical trench cross sections as shown on the drawings. Under no circumstances shall pipe be laid in water, on rock, or when trench conditions or weather is unsuitable for such work. Whenever the nature of the ground will permit,the excavations at the bottom of the trench shall have the shape and dimensions of the outside lower third of the circumference of the pipe, care being taken to secure a firm bearing support uniformly throughout the length ofthe pipe.A space shall be excavated under and around each bell to sufficient depth to relieve it of any load and to allow ample space for filling and finishing the joint. The pipe,when thus bedded firmly, shall be on the exact grade. In case the bed shaped in the bottom of the trench is too low,the pipe shall be completely removed from position, and earth of suitable quality shall be placed and thoroughly tamped to prepare a new foundation for the pipe. In no case shall the pipe be brought to grade by blocking up under the barrel or bell of same,but a new and uniform support must be provided for the full length of the pipe. Where rock or boulders are encountered in the bottom of the trench, the same shall be removed to such depth that no part of the pipe, when laid to grade, will be closer to the rock or boulders than six(6) inches. A suitably tamped and shaped foundation of approved material shall be placed to bring the bottom of the trench to proper subgrade over rock or boulders. Where the foundation material is found to be of poor supporting value, the Engineer may make minor adjustment in the location of the pipe to provide a more suitable foundation. Wherethis is not practical,the foundation shall be conditioned by removing the existing foundation material by undercutting to the depth as directed by the Engineer,within the limits established on the plans, and backfilling with either an approved material secured from unclassified excavation or borrow excavation at the nearest accessible location along the project, or foundation conditioning material consisting of crushed stone or gravel or a combination of sand and crushed stone or gravel approved by the Engineer as being suitable for the purpose intended. The selection of the type of backfill material to be used for foundation conditioning will be made by the Engineer. The Contractor shall remove all water,which may be encountered, or which may accumulate in the trenches by pumping or bailing and no pipes shall be laid until the water has been removed from the trench.Water so removed from the trench must be disposed of in such a manner as not to cause injury to work completed or in progress. 07120.5 PIPE LAYING Pipe shall be laid with bell ends facing in the direction of pipe laying,unless directed otherwise by the Engineer.

Proper tools, implements, and facilities satisfactory to the Engineer shall be provided and used for the safe and convenient prosecution of pipe laying. All pipe and other materials used in the laying of pipe will be lowered into the trench piece by piece by means of suitable equipment in such a manner to prevent damage to the pipe, materials, to the protective coating on the pipe materials, and to provide a safe working condition to all personnel in the trench.Each piece of pipe being lowered into the trench shall be clean, sound and free from defects.It shall be laid on the prepared foundation, as specified elsewhere to produce a straight line on a uniform grade, each pipe being laid so as to form a smooth and straight inside flow line.Pipe shall be removed at any time if broken,injured or displaced in the process of laying same, or of backfilling the trench. When cutting short lengths of pipe, a pipe cutter as approved by the Engineer will be used and care will be taken to make the cut at right angles to the centerline of the pipe or on the exact skew as shown on the plans. In the case of push-on pipe, the cut ends shall be tapered with a portable grinder, or coarse file to match the manufactured taper. During times when pipe laying is not in progress, the open ends of pipe shall be closed and no trench water or other material shall be permitted to enter the pipe. Where the pipe is laid on a grade of ten (10) percent or greater, the laying shall start at the bottom of the slope and proceed upward with the bell end of the new pipe upgrade.All pipe laid on a grade of ten(10)percent or greater shall require thrust blocking and keying as shown onthe drawings and standard details. Where pipelines of different materials are joined together a standard sewer repair coupling shall be used. The couplings shall be Eastern Standard Sewer Repair Couplings (Mission Rubber Company), the Fernco Joint Sealer Company or an equal product approved by the Engineer. Only one transition of dissimilar materials will be allowed between manholes. 07120.6 BACKFILLING All backfill shall be compacted so as not to damage the pipe and appurtenances and shall be compacted to ninety-five (95) percent of the Standard Proctor Test for the various types of backfill materials.

Acceptable products include Neenah Foundry, Sumter Machinery Co., Dewey Brothers Foundry, or an approved equal. The frame and cover shall be properly set in a bed of mortar and aligned to fit the top section of the manhole. Concrete brick, set in mortar, shall be used to adjust the top of the frame and cover to finished grade; however, no more than four (4) courses of brick will be used for adjustment. 07290.5 MANHOLE INVERTS Manhole inverts and benches shall be constructed in accordance with the standard details shown on the drawings. Invert shall be a U-shaped channel with a height of eight-tenths(0.8) of the diameter and be a smooth continuation of the pipe. The benches shall be constructed with a slope of one (1)inch per foot to the channel. The channel and invert shall be constructed with a minimum of 2000 psi concrete or brick fill with concrete finish minimum one(1)inch thick. Where sewer changes directions at the manhole, channel shall be constructed with a smooth curve with as large a radius as the diameter of the manhole will allow. 07290.6 MANHOLE DROPS Standard drop manholes will be constructed only at those locations shown on the drawings or as approved by the engineer. The design of the drop connection shall be in accordance with the standard detail drawing. The cost of the extra pipe, labor, etc. required to construct a drop manhole will be included in the unit price for the drop manhole at the depths listed. 07290.7 INSPECTION AND ACCEPTANCE Manholes shall be constructed to provide a true circular inside diameter with properly corbelled tops, satisfactory inverts and properly placed steps and castings. Any visible leaks in the manholes shall be completely stopped to the satisfaction of the Engineer. 07290.8 MANHOLE VENTS Where designated on the contract drawings, a four(4) inch diameter vent pipe shall be installed as an integral part of the manhole. The vent pipe is to be tapped in to the upper most section of the manhole, anchored in concrete and extended vertically to the elevation shown on the drawings. The pipe shall have a reverse bend and screen to prohibit rain and foreign materials from entering pipe. The pipe material shall be Schedule 40 Galvanized Steel with two coats of epoxy paint approved by the Engineer. 07290.9 MEASUREMENT AND PAYMENT The Engineer shall verify quantities of manholes installed in accordance with the requirements of this section in the field.

Payment shall constitute full compensation for furnishing all equipment, tools, labor and incidentals and performance of all work necessary to install the manholes as specified. SECTION 07295 SANITARY SEWER SERVICE CONNECTIONS 07295.1 DESCRIPTION OF WORK The work covered under this section shall consist of fiunishing all materials,labor,equipment, and services for the complete installation of a sanitary sewer service connection from the sanitary sewer (gravity) main line to the edge of the property to be served as shown on the project drawings. 07295.2 CONNECTION TO MAIN The standard sewer service connection shall be four (4) inches in diameter unless shown otherwise on the drawings,and shall connect to the main at a"wye"branch connection installed with the pipe line as it is being laid. The"wye" branch shall be of the same material as the main pipe line.Direct taps into the sewer main will not be acceptable unless approved by the Engineer prior to the laying of the main line. 07295.3 CONNECTION TO MANHOLE When shown on the drawings or directed by the Engineer, a sewer service connection shall be made into a manhole. The connection shall be made at the manhole invert. The invert shall be rebuilt so as to provide a smooth transition from service connection to main line. Inverts and benches shall be constructed in such a way as to prevent the deposition of solids in the manhole. 07295.4 SERVICE LINE The service line shall be installed from the "wye"branch connection to the edge of the public or utility right-of-way as shown on the plans. The sewer service line will be constructed of either PVC pipe(PVC schedule 40)pipe,or Ductile Iron(CL 350)as shown on the plans.When the service line pipe material is different from that of the main line a flexible, water tight, rubber transition coupling shall be used to join the service line to the "wye" connection. The service line shall be laid at a minimum grade of one (1.0) percent with a minimum cover of three(3.0) feet. Less than three(3)feet of cover will require the use of ductile iron pipe. 07295.5 CLEANOUT AND PLUG At the edge ofthe public or utility right-of-way a"cleanout" shall be installed. The cleanout shall consist of a"wye"branch connection,forty-five(45)degree bend,riser pipe,and threaded plug . installed flush with finished ground elevation. The end of the utility owner's sewer service connection shall terminate at the end of the pipe which will normally extend five(5)feet beyond the"wye"branch for the cleanout.A watertight plug shall be installed at the end of this line until such time as the property owner directs the utility owner to connect his facilities to the sewer system. 07295.6 MEASUREMENT AND PAYMENT Payment for the furnishing and installation of all service connections("wye" branches, service line, clean outs, plugs, couplings, etc.) as described in this section and as shown on the plans, shall be covered under the contract unit price bid for each Sewer Service Connection.
