Region 5

The General Services Administration Public Buildings Service Region 5, a sub-agency of the General Services Administration responsible for real-property acquisition and management across the Midwest, operates a large contract portfolio totaling $4.89 billion in combined potential value across 17,291 awards issued since 2002. Region 5 transacts almost entirely in real-estate leasing, facility services, and related property support; the portfolio reflects a decentralized vendor base supporting leasehold acquisitions for federal agencies across Illinois, Indiana, Michigan, Minnesota, Missouri, Ohio, and Wisconsin.

Region 5's recent activity shows declining volume: 886 awards in 2022, 902 in 2023, 807 in 2024, 473 in 2025, and 97 year-to-date in 2026. Combined dollars obligated stand at $4.06 billion, representing 83 percent of combined potential value. The 2,043 distinct prime contractors awarded across the portfolio indicate that competitive concentration in recent activity is moderately concentrated — Jones Lang Lasalle Americas, Inc. leads with 711 awards and $170.2 million in combined potential value over the last five years, followed by CMC & Maintenance Inc. (341 awards, $17.3 million) and J'S Associates, LLC (220 awards, $62.1 million). These three vendors account for 45 percent of recent award count but only 6 percent of combined potential value by volume, reflecting the highly fragmented dollar distribution across the long tail of smaller vendors.

The set-aside mix is dominated by open competition: 77 percent of awards carry no set-aside designation. Small-business set-asides account for 14 percent of awards (2,363 total awards), with 8(a) sole-source awards at 3 percent (538 awards). Woman-owned small business, service-disabled veteran-owned small business, HUBZone, and emerging small business awards each represent less than one percent of the portfolio; these categories have seen minimal historical take-up.
