GSA seeks a sole-source extension of CSOSA’s office lease at 800 North Capitol Street NW in Washington, DC. - Requirement: Extend lease LDC12624 to maintain occupancy of 73,421 rentable square feet (RSF), providing 62,987 building-owner-acceptable square feet (BOASF). - Purpose: Continue operations while replacement federally controlled space is delayed; the project schedule anticipates substantial completion in September 2027. - Value: The stated total contract value is $6,277,495.50. - Period detail: The attachment calls this an 18-month extension, but gives dates of October 1, 2026 through March 31, 2027, which is six months. It also states that the current lease expires September 30, 2026; the duration and dates therefore appear inconsistent and should be verified against the justification.
