The National Park Service requires a contractor to replace 26 sash windows with double-hung windows at the Courthouse in Yosemite Valley, California, leaving the existing frames in place. The project has an estimated construction magnitude of $25,000 to $100,000. This procurement is set aside exclusively for Small Business concerns under NAICS code 238910. The Government intends to award a single, firm-fixed-price contract based on an evaluation of price, technical capability, and past performance. An organized site visit is tentatively scheduled.
