Description

This contract calls for the repair and upgrade of the existing effluent diffuser outfall at the Four Rivers Sanitation Authority wastewater‑treatment plant in Rockford, Illinois. The work includes installing twelve new diffuser fittings, fabricating and installing a stainless‑steel debris screen inside a 66‑inch pipe, excavating and disposing of contaminated river‑bed material, and restoring the site (grading, seeding, erosion control). The contractor must provide all temporary facilities, obtain required USACE and Illinois EPA permits, and complete the work within a 30‑day “workable” schedule after receipt of a Notice to Proceed. The contract is a lump‑sum, fixed‑price award with a $42,000 cash allowance for hazardous material handling and a $300 per day liquidated‑damage clause.

Contract value

$400,000

The solicitation does not disclose a total contract price; only a $42,000 cash allowance for hazardous material handling is listed. Based on comparable river‑outfall upgrades (including diffuser installation, stainless‑steel screen fabrication, dredging, disposal, and site restoration) typical costs range from $250,000 to $600,000 depending on equipment mobilization, labor rates, and permitting. Considering the limited scope (12 diffuser fittings and a single debris screen) and the short 30‑day schedule, a reasonable midpoint estimate is roughly $400,000 total contract value.
