Budget estimate

$500,000 – $2,000,000

No contract amount is disclosed. Based on typical municipal roof‑and‑HVAC repair contracts of comparable size, a reasonable estimate ranges from a few hundred thousand dollars for modest repairs to a few million dollars for extensive work across multiple facilities. Assuming a mid‑size scope, the anticipated award could be roughly $500,000 to $2,000,000. Factors influencing the range include the total square footage of roof to be repaired, the number of HVAC units, material costs, labor rates (subject to prevailing wage), and any required upgrades or code‑compliant improvements.
