Budget estimate

$5,000,000 – $20,000,000

Based on typical municipal sewer rehabilitation contracts of similar scale, the total contract value is likely to fall between $5 million and $20 million. The range accounts for the size of Fairfax County’s sewer network, the extent of repairs required, and the competitive nature of the solicitation. Larger, more extensive rehabilitation segments push the estimate toward the high end, while a more limited scope would be closer to the low end.
