Open Market with Certified Business Enterprises (CBE)
For the purposes of this project, CBE is a unique certification through the District of Columbia’s Department of Small and Local Business Development (DSLBD)
This solicitation is part of the DC Clean Rivers Project for controlling combined sewer overflows (CSOs) to the District’s receiving waters. DC Water constructed several Green infrastructure (GI) facilities to manage a 1.2” storm event over 498 impervious acres in the Rock Creek and Potomac River sewersheds. As part of the construction associated with the implementation of this plan, DCCR has constructed GI facilities to manage the stormwater at its project sites and along Irving Street NW, to mitigate flooding in the Bloomingdale and LeDroit Park neighborhoods. The GI facilities are designed to reduce runoff volumes currently discharged to the collection system by temporarily capturing, infiltrating and evapotranspiration of stormwater before it discharges to the District’s waters and enters DC Water’s combined sewer system.
The purpose of the solicitation is to comply with the requirements of various permits issued by regulatory agencies and to meet the requirements of the Amended Consent Decree. The GI facilities are designed to reduce runoff volumes currently discharged to the collection system by temporarily storing, infiltrating and evapotranspiration of stormwater.
The scope of the GI Maintenance solicitation is to select a Contractor who will be responsible for maintaining bioretention, pervious pavements, green roof plantings and infrastructure, dry wells, flow restriction devices, overflow risers, inlets, inflow channels, and various types of GI facilities and stormwater underdrain systems, including local sewer connections at each GI facility.
The subject Solicitation would be posted on September 1st 2020 and will provide all the required information about the GI facilities, detailed scope of work, procurement process, content required in the proposal, submittal requirements, and evaluation process.
