Repair of gage house roof

The U.S. Geological Survey Office of Acquisitions and Grants seeks repair of the Gage House roof at the USGS Iowa Water Science Center in Iowa City, Iowa, with proposals due May 15, 2026 at 12:00 PM MST. This is a total small business set-aside under NAICS 238610, Roofing Contractors, with an estimated magnitude of less than $25,000.

The contract is firm fixed price with a period of performance from June 1 to July 31, 2026. Work includes removal of existing tile roofing (potentially containing asbestos), removal of roof sheathing, assessment and potential sistering of rafters, installation of 4-ply plywood sheathing (no OSB substitution), new 2"x6" facia boards, ice and snow guard adhesive, minimum 29-gauge painted ribbed roof steel with screwed fastening, matching color-coded trim, steel soffit and facia trim, and white steel ceiling with necessary trim. The scope statement clarifies that potentially a few rafters may require replacement but not all, and equipment may be driven onto adjacent grass areas. Site inspection is mandatory; an organized site visit is scheduled for May 5, 2026 at 9:00 AM CST at 300 S Riverside Drive, Iowa City, Iowa.

Contractors must commence work within 10 calendar days of notice to proceed and complete all work within 60 calendar days. Liquidated damages are $500 per calendar day of delay. Proposals must include completed SF-18 forms, acknowledgment of all three amendments, price schedules with schedule of values breakdown, representations and certifications, proof of liability insurance within 10 days of award, list of subcontractors, and weekly payroll documentation. The contract requires performance and payment bonds at 100 percent of contract price and compliance with prevailing wage per Department of Labor General Decision IA20260068. Evaluation weighs technical capabilities, qualifications, and relevant experience (minimum two projects within the last three years with similar installations) significantly more important than price. Amendments 0001 (April 15), 0002 (April 15, correcting site visit address and time zone), and 0003 (May 11, addressing rafter replacement and equipment access questions) require acknowledgment prior to submission.
