Request for Proposal EFMO 224159/318539, Rehabilit

NPS ConOps DSC Central in Denver, Colorado, is soliciting negotiated, firm-fixed-price construction offers on behalf of Effigy Mounds National Monument in Harpers Ferry, Iowa, to rehabilitate the Effigy Mounds Visitor Center and redesign and repave its visitor parking and maintenance area under Solicitation 140PP027R0001, with offers due December 7, 2026 at 2:00 PM local time. The Set Aside line reads No Set-Aside Used, although Amendment 0001 and Amendment 0002 Q&A summaries reference an ISBEE set-aside. A pre-proposal site visit is required, and additional visits must be coordinated with Contracting Officer Stormy Gallagher.

The NAICS code is 236220, Commercial and Institutional Building Construction, and the PSC is Z2QA. The magnitude of construction exceeds $10 million. Five base CLINs (0001-0005) and seven optional CLINs (0006-0012) are priced, and all option items must be priced regardless of acceptance. Base scope includes structural safety and foundation improvements, a temporary visitor center trailer, temporary office space and moves, collections relocation, and parking lot replacement. Work must be completed within 450 calendar days after notice to proceed. Liquidated damages are $1,363 per calendar day of delay. Performance and payment bonds are due within 10 calendar days of award, an offer guarantee is required, and offers must allow at least 60 calendar days for Government acceptance. Funds are not presently available, though the notice states a high expectation that they will become available for award.

Requirements include Davis-Bacon prevailing wage determinations, Buy American provisions, and an 85 percent small business subcontracting limitation for general construction. CLIN 0004 requires an IT specialist with network certifications and references for at least five similar government or NPS IT projects. Key personnel resumes, a Project Experience questionnaire, and past performance questionnaires are required. Evaluation includes a Project Experience subfactor under Section L.

Amendment 0002, issued November 9, 2026, is the most recent update. It adds addenda for CLINs 0004 and 0008, makes the key personnel resume form optional, and counts cover letters, tabs, and tables of contents toward page limits. Offers are not extended.
