Z--Remodel Golden Spike Visitor Center

The Department of the Interior, through the Northern Rockies Major Acquisition Office, is soliciting proposals for a Firm Fixed Price Construction Contract to remodel the approximately 4,500-square-foot Visitor Center at Golden Spike National Historical Park in Promontory Summit, Utah. This Total Small Business Set-Aside under NAICS code 236220 is limited to small businesses meeting the $45 million size standard and requires all offerors to be currently registered in SAM with active status and possess a Unique Entity Identifier and CAGE code. The scope includes extensive interior and exterior renovations to accommodate new exhibits, relocation of Western National Parks Association retail and National Park Service offices, renovation of the audiovisual storage room, updates to interior finishes, expansion of the building footprint by enclosing the north porch, and full HVAC and fire protection system modifications, including concealment of visible components. The work also encompasses site improvements to the north viewing plaza and access routes. The project has a mandatory 473-calendar-day performance period, with an assumed notice to proceed date of September 14, 2026, and requires completion of the main renovation by December 31, 2026, with two optional line items for administration area reconfiguration and exterior painting that may be exercised unilaterally by the Contracting Officer within 90 days of award. All proposals must be submitted in two PDF volumes via email to the Contracting Officer at Stacy_Vallie@ios.doi.gov, not exceeding 25 MB per email, with strict adherence to format, page size, and labeling requirements. Evaluation is based on an integrated best-value tradeoff assessing past performance, project experience, key personnel qualifications, schedule, safety, and price—with past performance and project experience deemed more important than the others, and non-price factors considered approximately equal in importance to price. The Contractor must meet stringent requirements for key personnel, including a Project Manager with five years of experience managing $2 million+ projects, a Superintendent with five years of field supervision, and an On-Site Safety Supervisor with demonstrated safety program experience. Compliance with federal sustainability mandates, Buy American provisions, prevailing wage rates under DOL Wage Determination UT20260081, ADA accessibility, hazardous materials handling, daily PPE inspections, and mandatory weekly and monthly safety meetings with documentation is required. Environmental sustainability demands biodegradable or recyclable packaging per ASTM D5834, minimal material usage, and source reduction practices. Payment must be processed electronically through the
