The U.S. Army Corps of Engineers seeks a fully serviced lease for approximately 555 ABOA square feet of office space in SeaTac, Washington, within SeaTac airport and a delineated area bounded by 154th Street, 188th Street, Military Road South, and Des Moines Memorial Drive South. The space must be ground-floor and meet Government security, fire/life-safety, and accessibility requirements; it cannot be in a 100-year floodplain/wetland unless no practicable alternative exists, near certain alcohol/firearm/marijuana/drug-treatment/detention uses, or involve subleases, and public transportation must be within 1,000 feet. The lease term is five years (60 months) with a fully serviced structure including base rent, CAM, utilities, janitorial supplies, and tenant alterations, plus 24/7 Government access. The Government currently occupies space in SeaTac Airport under an expiring lease and will consider alternatives if economically advantageous; a market survey is estimated for 11/15/2026, an appraisal/value estimate will determine fair market rental value, and funds may not be presently available so no award will be made until funds are available. Interested building owners or authorized representatives should review the RLP and submit electronic offers with the required exhibits, and SAM registration is mandatory at lease award.
