This document is an Amendment to a Request for Proposals (RFP) issued by the National Park Service (NPS) at Redwood National Park for the replacement of the existing roof on the Headquarters Building in Crescent City, California.

The RFP solicits proposals from small business contractors to provide all necessary supervision, labor, equipment, materials, and supplies to replace the adhered modified bitumen roof system with a new TPO membrane roof system. The work includes replacing damaged wood sheathing, roof hatches, gutters, drip edge, roof drains, and downspouts, as well as improving the building's thermal envelope. The existing rooftop solar array will be temporarily removed and then reinstalled. The contract period of performance is 9 months, from award in September 2024 through June 2025, allowing for a potential seasonal shutdown. This is a total small business set-aside with a NAICS code of 238160 (Roofing Contractors) and an estimated project range between $250,000 and $500,000. Award selection will be made on a best value determination considering price and other factors.
