Trask House Garage Reroof

The project involves the reroofing of the Trask House garage at Columbia State Historic Park in California to ensure the continued use of the structure for storing district office records and supplies. Work includes the removal of existing cedar shingles and the repair or replacement of damaged soffits, flashing, rafters, joists, and rafter tails using in-kind materials to maintain historical integrity. A new roof assembly will be installed featuring ½-inch OSB plywood over the existing skip sheeting, followed by a rubber underlayment and a layer of nylon cedar breather. White metal drip edge will be placed at the eaves, and 16-inch Class B fire-rated cedar shingles will be installed as the final roofing layer. Interior repairs involve removing and replacing damaged drywall, then taping, mudding, sanding, and painting to match the original ceiling finish. The work complies with the Secretary of the Interior’s Standards for the Treatment of Historic Properties and follows Weeks and Grimmer guidelines, ensuring preservation of the structure’s historical character. The project is being administered by the California Department of Parks and Recreation, Central Valley District, with primary point of contact Andrew Collum serving as Environmental Scientist and technical liaison. Performance is located at Columbia State Historic Park, specifically at the Trask House garage in Columbia, California, with all inspections and acceptance occurring on-site by the agency. The work qualifies for categorical exemptions under California Code of Regulations sections 15300.4, 15301, 15302, and 15331, indicating minimal environmental impact and streamlined approval. While the scope is clearly defined with detailed material specifications and historic preservation requirements, no contract value, pricing structure, performance period, payment details, or evaluation criteria are provided. The solicitation is classified as a forecast under NAICS code 238160, but standard federal acquisition clauses, contractual forms, delivery terms, or submission instructions are absent, reflecting the state-managed nature of the procurement and its reliance on existing preservation standards rather than federal procurement regulations.
