About this file
This design specification document, prepared for Colorado Parks and Wildlife, outlines the structural requirements for a box-riser installation project. The design components include one 3-foot box-riser structure, one 18-inch corrugated metal pipe (CMP) measuring 20 linear feet (with provisions to weld a 3-foot stub and band an additional 17-foot section if needed), one 18-inch CMP band as required, and four 6-foot 12-gauge sheetpiles. The box-riser structure must be fabricated from 12-gauge steel plate with continuous, watertight 16-inch fillet welds throughout all welded seams. All steel components must receive a black asphaltic coating for corrosion protection. The document indicates that alternative designs may be considered with approval from Colorado Parks and Wildlife Staff.
The specification document does not address pricing terms, set-asides, funding sources, response deadlines, or contract award information. No information regarding bidders' conferences, site visits, or contract renewal options is included in this technical specification.
