Replace safety railings at sutro bath

The National Park Service Pacific West Region is soliciting quotes to replace safety railings at the Sutro Baths tunnel within the Golden Gate National Recreation Area in San Francisco, California. The procurement involves acquiring metal railing components, specifically anodized aluminum speed railing systems with 1-1/2" diameter pipes and associated fittings, to construct three safety guard rails measuring 40' x 36", 35' x 36", and 15' x 36" at different tunnel locations. These railings are essential to prevent visitor falls along steep ocean-side edges where existing safety barriers are broken or missing. The evaluation will be conducted based on technical acceptability, past performance requiring descriptions of three similar completed projects, and price under a firm-fixed-price structure. Quotes must be submitted electronically to Quinn_Rankin@nps.gov by September 3, 2025, at 11:00 AM Pacific Time, with the contract period of performance running from September 8, 2025, through December 1, 2025.

This opportunity is designated as a total small business set-aside under NAICS code 332323 for Ornamental and Architectural Metal Work Manufacturing, with a size standard of 500 employees. The procurement involves specific quantities including 50 units of several railing component types and 12-60 units of pipes, though no incumbent contractor is identified in the documentation. The detailed specifications require anodized aluminum or stainless steel construction with precise dimensional requirements for various pipe fittings, elbows, tees, crosses, and flanges. Delivery must be coordinated with the Maintenance Mechanic Supervisor at 643 Old Mason Street in San Francisco, requiring 24-hour advance notice and occurring between 7:00 AM and 3:30 PM, Monday through Thursday. The National Park Service will handle installation using their own labor force, with the contractor responsible solely for manufacturing and delivering the railing components during the September 1 through December 1, 2025 performance period.
