Project Description: Dalecarlia Clearwells Maintenance and Improvements, Washington Aqueduct Division, Washington, DC.

The solicitation will be for a construction contract and it will be advertised as an invitation for bid (IFB) with a magnitude of $1M - $5M. The work includes architectural, structural, process mechanical, electrical and civil improvements to two subsurface concrete water storage structures (Clearwells), as well as adjacent buildings, grounds, and other ancillary equipment. The work will eliminate potential cross connections, increase reliability, and improve the function of the relevant structures and areas. The North American Industry Classification System (NAICS) for this requirement is 237110 (Water and Sewer Line and Related Structures Construction) and Business Size Standard of $39.5 Million.

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). At the Dalecarlia WTP, two Clearwells are used for final chemical treatment, disinfection, and storage of water before it is pumped to the distribution system. The 15 million gallon (MG) Clearwell is approximately 25 feet deep. It was constructed in the 1920s and rehabilitated in 2000. The 30 MG Clearwell was constructed in the 1950s and rehabilitated in the 2000s; its approximate depth ranges between 20’ and 50’. Both Clearwells are covered by about 2’ feet of soil and topped with grass cover.

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. Hence, an experienced contractor with resources and expertise to handle the following project constraints is needed:

1. The Clearwell roof surfaces have limited weight restrictions and the 30 MG Clearwell work must be completed between November and March. This work, including and testing the mixers and flow meters, must completed before work within the 15 MG Clearwell can begin.
2. The demolition and re-building of brick buildings must be done within a limited outage window during the winter months when the reservoir is out of service.
3. Access into the Clearwells and connecting conduit is limited and all work therein is considered confined space work.
4. When working in the Clearwells, the Contractor will be required to pump continuously to minimize the impact of water from leaking sluice gates.
5. The Maryland/DC border crosses through the project site. Therefore, the Contractor must be prepared to implement and maintain Erosion and Sediment Control measures from both jurisdictions.
    
   Interested qualified Small Business (SB), Small Disadvantaged Business (SDB), Service Disabled Veteran Owned SB (SDVOSB), Veteran-Owned Small Business (VOSB), Historically Underutilized Business Zones (HUBZones), or Qualified Section 8(a) certified firms should submit a concise narrative and specific project examples of similar size and scope that demonstrate their specialized experience and technical competence in:
    

1. Successful installation/rehabilitation of new and existing large, electronically actuated sluice gates in confined spaces with trained and certified personnel in a timely manner.
2. Successful installation of chemical induction mixers and acoustic flow meters, as well as associated support equipment, in confined spaces with trained and certified personnel in a timely manner.
3. Retrofitting of electrical, instrumentation, and controls for critical infrastructure components.
4. Remediation of black mold using appropriate environmental controls, personal protective equipment and installation of new HVAC equipment.
5. Utility re-route and commissioning.

Capability statements should include information and details of similar projects, to include contract value.
