The bedding of the pipe shall be Class "C" or better. 2. Excavating operations shall proceed only so far in advance of pipe-laying as will satisfy the needs for coordination of work and permit advance verification and unobstructed line and grade as planned. The amount of open or unfilled trench shall not exceed 500 feet unless ordered by the ENGINEER, and failure to comply with this requirement shall be cause for shut-down of the entire job until such back-filling is accomplished. All trench work MUST be confined to the right-of-way and easement areas as shown on the plans. Should trenches extend into side yard areas, the Contractor must be aware of the construction limits. Refer to the final plat for easements if they are not noted on the plans. SPU-3 SPU-4 Where interference with existing structures is possible or in any way indicated, and where necessary to establish elevation or direction for connection to in-place structures, the excavating shall be done at those locations in advance of the main operation so actual conditions will be exposed in sufficient time to make adjustments without resorting to extra work or unnecessary delay. 3.

The material placed in the top 3' of the trench as well as the aggregate base shall be compacted in the same manner to a minimum of 100% standard proctor dry density. Service trenches must be compacted in the same manner as the main trench. In areas where curb and gutter exists, sufficient curbing shall be removed to allow the prescribed compaction over the entire disturbed area. Utilities installed in "green" areas (not below pavement) shall be compacted to a minimum of 90% of standard proctor dry density. Utilities installed in "green" areas (not below pavement) adjacent to proposed or existing houses shall be compacted to the same requirements as under streets. At the time of compaction, the moisture content of the embankment material shall be not more than 4% over the soil's optimum moisture content, as determined by standard proctor, where a minimum of 95% of standard proctor dry density is required, and shall be not less than 65% nor more than 102% of the soil's optimum moisture content, as determined by standard proctor, where a minimum of 100% of standard proctor dry density is required. The minimum moisture requirement shall not apply to materials classified by the ENGINEER as Granular Material, nor shall the above specified moisture controls apply to materials placed without specific density control. However, all materials placed without moisture. control shall be subject to the specified layer construction requirements. The soils report, as represented on this project, may contain additional or more stringent requirements. In all cases, the soils report shall govern the construction techniques used with respect to the compactive efforts on this project. The CONTRACTOR is responsible for obtaining and understanding all requirements within this report. In all cases, the CONTRACTOR shall blade and compact the roadway after the trench has been backfilled, so that it shall be passable to traffic and in a free draining condition at all times. The CONTRACTOR shall maintain the roadway in a condition acceptable to the ENGINEER at all times until final approval of the entire work by the OWNER. Water shall be used for dust control and moisture conditioning of the soil and shall be applied as directed by the ENGINEER. The CONTRACTOR shall remedy, at his own expense, any defects that appear in the backfill for a period of one year following the final written letter of acceptance of the project from the City and or ENGINEER. D. Testing Prior to final acceptance of each section of sewer line, the CONTRACTOR shall flush a ball, the full diameter of the sewer, through the line. This shall be done to remove any dirt or debris SPU-5 SPU-6 which has entered the new installation. The dirt and debris shall be prevented from entering the existing sewer system by means of water-tight plugs or other suitable methods. The Contractor shall televise all sanitary sewer mains after construction is complete. The Contractor shall give the City 48 hour notice prior to the start of any test and all testing must be witnessed by a City Representative. Each reach of the sewer shall meet the requirements of the following tests: 1. Leakage tests i. Upon completion of the mainline, services and manhole installation. 11. Hydrostatic Pressure Test 111. Air Test Method The following paragraph shall replace paragraph 2 of the Air test method listed in the CEAM Specifications. After the temperature has been allowed to stabilize for the two minute period, the air supply shall be disconnected, and the pressure is allowed to decrease to 3.5 psig. At the 3.5 psig the stopwatch is started to determine the time requiredfor the pressure to drop to 2.5 psig. The time shall be equal or greaterthan the allowable time as follows: Pipe Time Size (min.-see) 6" 2:15 8" 3:18 10" 3.-57 12" 5:40 15" 7:05 18" 8:30 21 " 9:50 24" 11:20 2. Deflection Testing - The CONTRACTOR shall measure deflection ofPVC sewer pipe not sooner than 30 days after placement of backfill material in the trench and prior to acceptance of the project.

The amount of open or unfilled trench shall not exceed 500 feet unless ordered by the ENGINEER, and failure to comply with this requirement shall be cause for shutdown of the entire job until such backfilling is accomplished. Where interference with existing structures is possible, or in any way indicated, and where necessary to establish elevation or direction for connections to in-place structures, the excavating shall be done at those locations in advance of the main operation so actual conditions will be exposed in sufficient time to make adjustments without resorting to extra work or unnecessary delay. 2. Class C bedding shall be used to bed the pipe. The pipe shall be placed with ordinary care on earth foundation, shaped to closely fit the width of at least 50% of the pipe breadth. The remainder of the pipe shall be backfilled to a height of 12 inches above the pipe with the material hand shovel-placed and thoroughly tamped in 6" layers to completely fill all the voids around the pipe. 3. All plugs, caps, tees, bends, hydrants, and other thrust points shall be restrained with retainer glands or tie-bars. When tie-bars are used with steel bands around the pipe barrel, only one rod should be attached. to each band and the band should be cocked to prevent slippage along the pipe barrel. A band placed behind the bell may be used for two rods. For mechanical joint pipe, tie rods may be threaded through the bolt-holes in the flange and secured by nuts. All rods and bands should be made of corrosion-resistant SPU-13 material or coated to prevent rust or deterioration. All methods of restraint shall be approved by the ENGINEER prior to construction. 4. The bottom of the water main and water services shall be laid at least 18 inches above the top of the sewer. Where this vertical separation cannot be obtained, the sewer shall be constructed of materials and with joints that are equivalent to water main standards of construction and shall be pressure tested to assure water tightness prior to backfilling; or shall have a ten (10) foot horizontal separation. 5. Water mains crossing house sewers, storm sewer, or sanitary sewers shall be laid to provide a separation of at least 18 inches between the bottom of the water main and the top of the sewer. When local conditions prevent a vertical separation as described, the following construction shall be used: a. Sewers passing less than 18 inches above or below water mains shall be constructed of materials equal to water main standards of construction. b. In addition, sewers passing over water mains shall be protected by providing: 1) a vertical separation of at least 18 inches between the bottom of the sewer and the top of the water main, 2) adequate structural support for the sewers to prevent excessive deflection of joints and settling on and breaking the water mains. C. Backfilling and Trench Compaction All backfilling and trench compaction requirements are identical to the requirements as previously stated under Paragraph 3. Sanitary Sewer and Storm Sewer Item C. Backfilling and Trench Compaction. D. Testing 1. Pressure and Leakage Tests i. Upon completion of water main, hydrants and services. 11.
