Budget estimate

$130,000 – $165,000

The engineer’s estimate for the project is $145,000. Assuming the contractor’s profit margin ranges from 5‑15 % of the total contract value, the expected revenue to the winning bidder would likely fall between roughly $130,000 (tight margin) and $165,000 (generous margin). Factors influencing the final budget include material choices (e.g., premium membrane vs. standard), site access conditions, and any unforeseen structural repairs uncovered during demolition.
