About this opportunity
The General Services Administration Public Buildings Service Central Office Office of Leasing has awarded contract GS-05P-LIL16200 to extend a lease for office space and parking in Des Plaines, Illinois on a sole-source basis on August 26, 2026.
The extension serves as interim housing for the Department of Transportation Federal Aviation Administration while a replacement long-term leased location (Prospectus PIL-01-OH22, awarded September 29, 2023) undergoes construction and preparation for occupancy. The current lease, which expires October 20, 2026, encompasses 158,137 ABOA/188,768 rentable square feet of office space and 760 parking spaces. The requested extension is for 9 months with 6 months firm, commencing October 21, 2026. The FAA has occupied this location continuously since 1971.
The justification cites 41 U.S.C. 3304(a)(1) and implements authority through FAR 6.103-1 and GSAR 570.405, which permit sole-source extensions when agencies experience delays preparing replacement federal space. Market research conducted July 27, 2026, using CoStar identified no comparable properties meeting the square footage requirement in the delineated O'Hare Office Submarket area. Relocation costs are estimated in the millions of dollars, including tenant improvement costs, security systems costs, and IT costs, making continuation at the existing location cost-advantageous to the Government. Place of performance is 2300 E Devon Avenue, Des Plaines, Illinois. The document was executed August 14–19, 2026, and approved by the Head of Contracting Activity.
