The District of Columbia Department of General Services (“DGS” or “Department”) is issuing this Request for Proposals (“RFP”) to engage a contractor to design and construct a permanent supportive housing facility (“Permanent Supportive Housing Facility”). The site is located at 4300 – 4304 12th Street, NE, Washington, DC. Currently, the site is occupied by an abandoned three story building having a footprint of approximately 7,250 square foot (approximately 23% S1 lot occupancy). The existing structures will be demolished by a separate contractor prior to the start of construction. The new facility will be a three-story building with approximately 30,000 square feet, and should include 26 units of a combination of two and three bedrooms per unit S2, as well as ground floor office space for the provision of supportive social services. The Department is open to traditional construction methods as well as prefabricated construction to be assembled on-site. The Department is in the process of confirming any zoning restrictions, but for purposes of this procurement, Offerors should assume they can construct the new facility within the current building envelope restrictions. A copy of the Department’s performance specifications is attached hereto as Attachment A (the “Performance Specifications”).
