Budget estimate

$250,000 – $400,000

Based on typical commercial TPO roof installations in the Mid‑Atlantic (≈ $6‑$10 per square foot) and the stated roof area of ~36,800 sf, the contract value is likely between $220,000 and $370,000. Adding the $60,000 owner’s allowance and contingency for ancillary work (flashings, hatches, lightning protection) pushes the probable award range to roughly $250,000‑$400,000. The estimate assumes standard material costs, labor under prevailing‑wage rates, and a moderate profit margin.
