About the company
United Door And Dock LLC, doing business as United Perimeter Security, is a minority-owned, small disadvantaged business based in Glendale Heights, Illinois, that manufactures and installs perimeter security equipment — rolling dock doors, parking lot gates, and vehicle barrier systems — for federal facilities as a prime contractor (67% of recent awards) and as a subcontractor on federal building renovation projects. The vendor is Asian-Pacific American owned, self-certified as a small disadvantaged business, and DOT-certified as a disadvantaged business enterprise.
Recent prime work includes a $24,940 total small business set-aside purchase order from the Social Security Administration (September 2024) for the purchase, delivery, and installation of a rolling high-speed dock door at the Harold Washington Social Security Center in Chicago, and a $37,250 full-and-open purchase order from the General Services Administration's Public Buildings Service Region 5 (July 2023) to replace parking lot gates at the Findley Federal Building in Springfield, Illinois. The vendor operates under a single GSA indefinite delivery contract (47PF0019D0027) and places work through one-off purchase orders rather than recurring task order vehicles.
Customer concentration is limited to two agencies — the General Services Administration's Public Buildings Service Region 5 (2 awards, $37 thousand combined potential value) and the Social Security Administration (1 award, $25 thousand) — representing the entirety of the vendor's tracked federal footprint. As a subcontractor, United Door And Dock LLC performed vehicle barrier replacement work under Charpie Construction Co., Inc. on a federal building renovation project at the John C. Kluczynski U.S. Federal Building in Chicago in August 2023. Recent activity has been light — two awards in 2023 and one in 2024 — with a combined potential value of $62 thousand across all three awards. The vendor's NAICS spread spans commercial building construction, building equipment contracting, and specialty trade contracting, reflecting a narrow focus on perimeter security hardware and installation services for federal real estate customers in the Midwest region.
