The National Park Service Denver Service Center issued a pre-solicitation notice on October 5, 2026, announcing its intent to issue RFP 140PP027R0001 for rehabilitation of the visitor center and redesign and repaving of the visitor parking and maintenance area at Effigy Mounds National Monument in Iowa, with formal solicitation documents due November 11, 2026. The requirement is set aside for Indian Small Business Economic Enterprises (ISBE) under the $45 million size standard. Construction magnitude exceeds $10 million, structured as Firm-Fixed-Price with an anticipated 450 calendar-day performance period. Visitor center work includes selective demolition, hazardous materials removal, new mechanical and electrical systems, structural improvements, windows, roofing, interior and exterior finishes, restroom relocation, and new drainage and visitor plaza. Parking improvements encompass vehicle and pedestrian circulation, drainage enhancements, asphalt resurfacing with curbs, gutters, sidewalks, and visitor amenities. Award will be made using best-value trade-off evaluation (FAR 15.101-1), with technical factors—Project Experience, Technical Approach, Management Approach, Schedule, Key Personnel, Safety, and Past Performance—weighted significantly more important than price. Bid, Performance, and Payment Bonds are required. The requirement is currently unfunded with high expectation of funding availability. A pre-proposal conference and site visit will be held after RFP issuance with virtual attendance options. Prospective offerors must maintain active SAM.gov registration with a UEI number.
