Solicitation # 140FGA26R0023

The U.S. Fish and Wildlife Service, under the Department of the Interior, is conducting market research for the Boat Ramp Replacement Project at Kirwin National Wildlife Refuge in Kirwin, Kansas, using solicitation number 140FGA26R0023. This effort is a Sources Sought Notice, not a formal solicitation, meaning no proposals are being accepted and no contract will be awarded based on this notice. The purpose is to gather industry information to inform future procurement planning. The NAICS code is 237990, and the procurement is designated as a Total Small Business Set-Aside under FAR 19.5, restricting eligibility to small businesses only. The project requires the demolition of three deteriorated concrete boat ramps and one concrete bulkhead at each of two sites, followed by the construction of two new double-lane concrete boat ramps. Each ramp must be 20 feet wide, 6 inches thick, made of 4,000 psi concrete reinforced with #4 epoxy-coated rebar spaced 12 inches on center, and finished with a 1-inch deep non-skid V-groove textured surface angled at 30 degrees. The work includes extending two existing wave breaks by approximately 40 feet using riprap and a minimum 8 oz non-woven geotextile underlayment meeting AASHTO M288, as well as dredging accumulated sediments from ramp and maneuvering areas. All work must support AASHTO HS-20 loads, achieve 95% of maximum dry density per ASTM D1557, and comply with the Clean Water Act, OSHA, and other federal, state, and local environmental and safety regulations. Environmental protections are central to the project, requiring implementation of Best Management Practices to safeguard water quality and wildlife habitats. A perimeter turbidity curtain must be installed prior to work and inspected daily, and a dedicated washout area for concrete trucks must be constructed to prevent contamination. Fueling and equipment maintenance within 100 feet of water are prohibited unless secondary containment is provided, and any spills must be immediately contained and reported. Concrete runoff or uncured material must never enter the water. Contractors may use onsite water, sewer, and electricity only if no damage is caused, and emergency work may be required outside normal hours to prevent damage to government property. Quality control must follow industry standards and be available upon request, with all installations complying with manufacturer specifications and applicable codes including OSHA
