Budget estimate

$2,000,000 – $2,800,000

The solicitation lists a project‑estimated budget of $2,770,000. After accounting for typical contractor overhead, profit margins (10‑15 %), and potential change orders, the realistic earnings for the prime contractor are likely between $2.0 million and $2.8 million. The lower bound assumes a tighter profit margin and possible cost overruns, while the upper bound reflects full budget capture with standard overhead.
