Budget estimate

$500,000 – $2,000,000

The solicitation cites a total project value of “$10,000,000+”. Assuming the prime contractor retains a typical margin of 10‑20% and a subcontractor like the client could capture a 5‑15% share of the overall work, the expected earnings could range roughly from $500,000 up to $2,000,000, depending on scope depth, subcontractor utilization goals, and negotiated rates.
