25-02-95-01, Wetland Restoration, Hogsback WMA, Winnebago County

The Iowa Department of Natural Resources (IDNR) is soliciting competitive bids for the Hogsback Wildlife Management Area (WMA) Wetland Restoration project, identified as Project #25-02-95-01, located in Winnebago County. The procurement is a unit price-based contract for comprehensive wetland restoration services involving multiple specific construction activities. Key deliverables include constructing two dikes, performing 3,300 cubic yards of shallow water and spillway excavation, installing 1,940 feet of 8" non-perforated dual wall tile, conducting 1,500 feet of tile investigation, creating 5 tile breaks, installing 10 feet of 10" CMP with rodent guard, and placing 100 feet of straw wattles and 25 tons of clean stone. Contractors must access the site from 210th Avenue and follow precise IDNR engineer specifications for site preparation, material sourcing, and construction techniques. The bid response is due by 3:00 PM on October 9, 2025, and must be submitted electronically via the Iowa IMPACS system, with project completion required by December 1, 2025. Qualified bidders must possess an Iowa Contractor Registration Number and demonstrate capability to execute the comprehensive site restoration and drainage improvement work.

The contract includes provisions for potential federal funding, which introduces several compliance requirements for potential bidders, including minority and women's business enterprise participation guidelines. The IDNR reserves the right to withhold up to 5% of the contract amount and will assess liquidated damages of $1,000 per calendar day for delays beyond the specified completion date. While no specific set-aside designations are explicitly detailed, the project appears to encourage participation from diverse contractors through its federal funding compliance standards. The contract will be awarded to the lowest responsive and responsible bidder, with the department maintaining discretion to not award a contract if submissions do not meet their requirements. Though no specific budget range is provided, the comprehensive nature of the project involving significant earthwork, drainage infrastructure, and restoration suggests a substantial project investment. Bidders should be prepared to demonstrate technical expertise in wetland restoration, drainage infrastructure installation, and compliance with Iowa Statewide Urban Design and Specifications (SUDAS) standards.
