South Rivanna Water Treatment Plant Flocculator Replacement

The Rivanna Water and Sewer Authority in Albemarle County, Virginia is requesting bids for replacement of the flocculation system at the South Rivanna Water Treatment Plant under IFB No. 446, with bids due August 31, 2026 at 3:00 PM. A non-mandatory online pre-bid meeting is scheduled for August 11, 2026 at 11:00 AM EST, followed by a site visit.

The project scope includes selective demolition and installation of three new flocculators, associated concrete supports, fiberglass reinforced plastic (FRP) baffle walls, flocculator drive motors, sprockets, chains, and variable frequency drives (VFDs), plus integration of additional inputs and outputs into the SCADA system. Enduro Composites FRP baffle wall systems are specified with detailed installation and maintenance guidelines. The contractor must visit the site to assess existing conditions; failure to do so waives claims related to site conditions.

Virginia contractor licensing is mandatory: Class A licensing for contracts of $150,000 or more, or Class B licensing for contracts between $30,000 and $150,000. Any bid exceeding $500,000 requires a standard bid bond equal to five percent of the bid amount, plus standard performance and labor/material payment bonds.

The contractor shall achieve substantial completion within 500 consecutive calendar days from notice to proceed, with final completion within 30 days thereafter. Liquidated damages are $750 per calendar day for work remaining beyond the completion deadline. The contract award will be based on the lowest responsive and responsible bidder.

Bids are accepted in-person at the Rivanna Administration Building (697 Moores Creek Lane, Charlottesville, VA 22902-9016) or electronically via the eVA system. The project engineer is Short Elliott Hendrickson Inc., with Nate Nickerson (434.202.6627) and Matt Nguyen (651.302.7670) as project management contacts. The owner's project manager is David White III (434.977.2970, Ext. 158).
