Budget estimate

$35,000 – $70,000

The engineer’s estimate for the project is $350,000. Assuming typical contractor margins of 10‑20 % for a specialized HVAC‑plumbing retrofit, the net earnings for the winning bidder would likely fall between $35,000 and $70,000. Factors influencing this range include the exact scope of ancillary work, material costs for the heat‑pump system, and any change orders during construction.
