Budget estimate

$650,000 – $1,500,000

The solicitation lists an engineer’s estimate of $13‑15 million for the construction work. Assuming a typical contractor profit margin of 5‑10 % on public‑sector projects, the net earnings for the successful bidder would likely range from roughly $650,000 at the low end (5 % of $13 M) to about $1,500,000 at the high end (10 % of $15 M). Additional revenue could be generated from change orders, but the base estimate provides a solid baseline for the expected budget.
