14. A detail for the sewer line casing and casing spacer installation is attached. Use it for the sewer line . crossing the drainage structure on page 4(Washington Street sewer line). The casing spacers for the sewer line creek crossing shall meet the following requirements: Casing spacers shall be used to install the carrier pipe inside the encasement pipe. Casing spacers shall fasten tightly onto the carrier pipe so that when the carrier pipe is being installed the spacers will not move along the pipeline. Casing spacers shall be doubled on each end of the encasement. Each casing spacer shall be capable of providing support for the eazrier pipe in service at a maximum spacing of 101. Calculations shall be provided to the ENGINEER by the casing spacer manufacturer showing that the casing spacer will support the service load at the recommended spacing, including a factor of safety of two (2). Casing spacers used under this specification shall meet or exceed the specifications described herein as projection-type casing spacers. Projection-type casing spacers shall be constructed of preformed secrions of high density polyethylene. The flexible sections shall be joined together around the pipe to provide a minimum of 16 plastic projections per spacer section. Projection-type casing spacers shall be "RACI" Type F/G spacers, manufactured by Recon Pipe Corporation of Vernon, British Columbia, telephone (604) 545-2227, or equivalent. 15. Water service details of page 7 of the drawings-The CONTRACTOR will be responsible for installing the new service line to connect to the existing meter in the existing water meter box. If the existing box is defective then the OWNER will provide a new meter box for the CONTRACTOR to install. 16. The CONTRACTOR shall re-grass all areas disturbed by his construction activity. It shall be his responsibility to reestablish grass cover to 75% of the disturbed area. Cool season grasses such as rye and fescue will be required to be seeded if the construction is completed after September 15. Bermuda grass will be used prior to that date. All fertilizing, soil testing, watering, disking, etc. that is required to establish this amount of coverage is required. Contractor shall include in his bid enough to install sod blocks of San Augustine grass on 1,000 total square feet in shaded areas under trees. Install sod for 50°/a coverage of disturbed areas (checkerboard pattern). 17. All backfill in trenches where driveways or sidewalks are to be replaced will be installed in maximum 8" loose lifts of native material, compacted to a minimum of 95% standazd proctor density at -1 to +3% of optimum moisture. The OWNER shall bear the cost of successful testing, and the CONTRACTOR shall pay for tests that fail. 18. The OWNER will be responsible for removing and replacing all sidewalks shown to be removed and replaced on the project. The CONTRACTOR shall be responsible for saw cutting and removing portions of concrete driveways that are necessary to install pipe with trenching. The OWNER will be responsible for making the concrete repairs at these locations. 19. With respect to bidding the fire hydrants, the fire hydrants and isolation gate valves will be furnished by the OWNER, but not the ductile iron tee. 20. Although the OWNER will provide valves, the CONTRACTOR will provide the valve boxes, extensions, and lids. ; -~*•~'d~~~~, : . o E .o•O '••DF'}' P T ~Z HAYTER ENGINEERING ~•9s tP TBPE # F-000315 ~ _ 1Cf-lA~~ PJ.TIBB~:TS~ ~ ew « •r•.u••~ r/ 7 • 65484 Michael N Tibbets, P.E. ~G.$T~~ ProjectManager ~ , 2 ~ 000265
