Budget estimate

$500,000 – $6,000,000

The contract ceiling is $6 M over six years, so annual spending could range from a few hundred thousand dollars to the full amount if many task orders are issued. A realistic estimate for a consulting firm would be between $500 k and $6 M total, depending on the volume of inspections and engineering tasks awarded.
