Specifications include, but are not limited to: Steel Rim Specifications Only new materials will be supplied and installed by the vendor. Any construction that varies from the specifications must be approved by the Wildlife Area Manager in writing. The steel rim is preferred to be a Hastings brand or equivalent. If vendor is bidding an equivalent brand detailed specifications must be provided for review team to verify the equivalent option meets or exceeds specifications. If vendor does not provide sufficient documentation for the equivalent option, their bid will be disqualified. The following specifications are in reference to a Hastings brand 10 GA bottomless stock tank, 20’ in diameter, 26” high which will hold approximately 3,900 gallons of water as constructed. Sheets will be notched on the end for complete compression of the seams. The seams shall overlap 2.25” and be sealed with butyl tape along with a double row of .3125” steel bolts. Sections: 8 Diameter: 20’ Approximate Capacity: 3900 gallons Weight: 1104 lbs. Rim to be embedded in concrete 2.25” Contractor shall use manufacturer’s recommended design for rim assembly. The steel rim may be rested on bricks to achieve the desired position in the concrete. The finished rim shall be completely level in elevation. Site Preparation The contractor is responsible for all equipment and labor to construct a suitable level location for construction as well as removal and disposal of the old concrete pads. The contractor will be responsible for calling in for the locations of any buried utilities. The Wildlife Area Manager will mark the location of underground water lines owned by KDWPT. The contractor will be responsible for backfilling the area adjacent to the finished concrete so that the ground level and the top of the concrete are at the same elevation. Floor Reinforcement 5/8” rebar (minimum) shall be used in the concrete set in a grid pattern at 12” each way. All splices shall be lapped 12” Rebar shall be raised to an elevation of 2” above the bottom of the floor slab with concrete chairs capable of supporting the weight of the rebar and the steel rim. There shall be 3” clearance from the edge of the slab to the rebar. Overflow Pipe All pipe and fittings used in the construction of an overflow pipe shall be 2” galvanized steel pipe. The overflow pipe shall be positioned approximately 18” inside the steel rim to allow for removal and maintenance from outside the tank. A 2” galvanized coupling shall be depressed 1” from the top of the cement slab to allow the tank to completely drain when the vertical portion of the overflow pipe is unscrewed. The vertical portion of the overflow pipe shall be set so that water will flow through the pipe approximately 2” before overflowing the rim of the tank. The top of the overflow pipe shall be threaded to allow for the addition of a 90-degree elbow to be placed on top to reduce vegetation restricting the flow. This must be considered when setting the elevation of the overflow pipe. The required length of underground overflow pipe at all stock tank site locations will be 45 feet. Concrete Concrete shall be 4,000 psi (min.) concrete at 28 day test a minimum of 6” in depth. The depth shall be uniform throughout the pour, both inside and outside the steel rim. The concrete shall have a broomed finish. Contractor is responsible for ensuring concrete trucks can access each site including providing equipment to assist with pulling the concrete trucks, if necessary. The Wildlife Area Manager will designate an area at each site for any extra concrete to be placed.
