Budget estimate

$170,000 – $440,000

The solicitation lists an estimated bid range of $3.4 M to $4.4 M. Assuming the contractor’s profit margin for a construction project of this size averages 5‑10 % after accounting for labor, materials, overhead, and subcontractor costs, the expected net earnings would likely fall between roughly $170,000 and $440,000. Factors influencing the final budget include the chosen HVAC equipment specifications, roof material selections, subcontractor pricing, and the extent of apprentice labor credits.
