Budget estimate

$6,000,000 – $12,000,000

The Engineer’s probable cost is $123 million. Assuming a typical contractor profit margin of 5‑10 % for large civil infrastructure projects, the net award to the winning bidder would likely fall between $6.2 million and $12.3 million. Factors influencing the final budget include the bidder’s ability to manage risk, the final negotiated unit‑price adjustments, and any change orders during the 1,250‑day construction period.
