The U.S. Army Corps of Engineers, Baltimore District (NAB), has been tasked to solicit for and award construction services for Dalecarlia Clearwells Maintenance at the Washington Aqueduct in Washington, DC. The proposed project will be a competitive, firm-fixed-price, contract procured in accordance with FAR 14, Sealed Bidding, via an Invitation for Bid (IFB). The Washington Aqueduct provides potable water to approximately one million people in the District of Columbia and Northern Virginia. As part of the water treatment and supply system, the Washington Aqueduct maintains and operates the Dalecarlia and McMillan Water Treatment Plants (WTPs). The project consists of implementing upgrades and improvements to these Clearwells and their connecting conduits to include: upgrades to their drain lines to eliminate potential cross connections, rehabilitation and replacement of large sluice gates, installation of new flow meters and induction mixers, improvements to the Clearwell overflow structure, chemical analyzer drain pipe re-routing and soil drainage improvements Both Clearwells are critical in maintaining adequate supply and quantity of water, so outage periods are restricted. The timing of outages must be coordinated with lower seasonal demands and sequenced so that only one Clearwell is out of service at a time. Finally, mold remediation and HVAC upgrades will be required in a building adjacent to the 15 MG Clearwell. Magnitude of Construction is Between $1,000,000 and $5,000,000. This will be solicited via full and open competition.
