Budget estimate

$200,000 – $600,000

The solicitation estimates the total project cost at $4 million‑$6 million. Assuming a typical contractor gross profit margin of 5 %–10 % for a civil construction project of this size, the expected earnings for the winning bidder would be roughly $200,000 to $600,000. This range accounts for the scope (culvert, roundabout, utility relocations, paving, lighting) and the required bonding/insurance costs, which can affect net profitability.
