The project is budgeted at $700 K, requires a California C‑39 contractor license, and is subject to prevailing‑wage rules and a $1,000 per day liquidated‑damages clause for late completion. Bidders must attend a mandatory pre‑bid conference on January 26, 2026 and submit bids by February 10, 2026.

Budget estimate

$650,000 – $750,000

The engineer’s estimated cost for the project is $700,000, which serves as a solid proxy for the contract value. Considering typical contractor profit margins of 5‑10 % for specialty roofing work and potential change‑order allowances, the expected budget to the winning firm would likely fall between $650,000 and $750,000. Factors influencing the range include material price fluctuations, labor rates, and the scope of any additional work uncovered during site inspections.
