About the company
William P. Gelberg Inc., operating through its Gelberg Signs Division, manufactures and installs signs and identification systems for federal agencies as a prime contractor on full-and-open definitive contracts and as a specialized subcontractor on federal construction and renovation projects. The vendor is a minority-owned, woman-owned, Asian-Pacific American-owned for-profit manufacturer based in Washington, DC, competing without set-aside designations across recent prime awards.
William P. Gelberg's federal footprint is concentrated in cultural and civic institutions. The National Gallery of Art dominates by potential value, accounting for two recent prime awards totaling $902 thousand—a $586 thousand sign fabrication contract running through April 1, 2027, and a $315 thousand sign manufacturing contract with an ultimate completion date of December 31, 2027. The Smithsonian Institution represents the second-largest customer by award count (four awards, $64 thousand combined potential value), with the General Services Administration Public Buildings Service, the Department of Veterans Affairs, the Department of Homeland Security, and the Department of Defense Missile Defense Agency comprising the remainder of the active customer base. Across fourteen prime awards spanning the last five years, the vendor has delivered one or two awards annually, with $902 thousand in combined potential value completing within the next twenty-four months.
William P. Gelberg's capability portfolio centers on sign manufacturing (4 awards), commercial and institutional building construction and installation work (4 awards), and graphic design services (1 award), with place of performance consistently in Washington, DC. The vendor sits on two indefinite delivery contracts—IDC 47PM0518D0007 and IDC W912DY17D0018—with one task order each. As a subcontractor, William P. Gelberg performs sign fabrication and installation work under Global Engineering & Construction LLC on a construction renovation sub task (awarded December 3, 2025) and under Structural Engineering Group Inc. on signage work for the Ronald Reagan Building memorial (awarded May 6, 2023). The Service Contract Inventory dataset captures minimal activity—1.5 FTEs in FY2022 and 1.2 FTEs in FY2024 across two named-subcontractor records—reflecting the vendor's primary focus on goods manufacturing and installation rather than labor-intensive service contracts above the $150,000 reporting threshold. Combined dollars obligated ($2.4 million) exceed combined potential value ($988 thousand) by 142%, indicating completion of older awards and draw-downs below ceiling on recent contracts.
