About the company
Gunn Building PTY LTD, a for-profit construction and facilities maintenance contractor based in Canberra, Australia, operates exclusively as a prime contractor (100% of awards) delivering site restoration, building renovation, roof maintenance, and accessibility modifications to the U.S. Department of State's Bureau of Overseas Building Operations at U.S. government facilities throughout the Australian Capital Territory. The vendor competes on full-and-open competitive basis without set-aside designations; all sixteen recent awards are firm fixed-price purchase orders issued through Request for Quotes processes and awarded to the lowest-priced acceptable offeror.
Gunn Building PTY LTD's customer concentration is singular and geographically focused. The Department of State Bureau of Overseas Building Operations accounts for 15 of 16 awards (94% of the portfolio, $1.2 million combined potential value), with one award from the Department of State Bureau of East Asian and Pacific Affairs ($173 thousand). The vendor's recent work scope includes a $129.6 thousand renovation of bathroom and pedestrian access at the Ambassador's Residence in Canberra to meet Architectural Barriers Act accessibility standards (awarded July 17, 2025, completion December 30, 2025); a $103.6 thousand car park retaining wall construction at the U.S. Embassy compound in Harman, Australian Capital Territory (awarded August 21, 2025, completion March 30, 2026); roof maintenance and repair work; kitchen and bathroom renovations; gym restorations; and general building maintenance on official housing facilities. Award values across the portfolio range from approximately $11 thousand to $156.7 thousand.
Activity has declined over the period tracked. The vendor received seven awards in 2021, four in 2022, one in 2024, two in 2025, and one in 2026 (three months ago), with the combined obligated value across all sixteen awards totaling $1.4 million — a fully obligated portfolio with no unexercised ceiling value. The vendor operates without federal parent vehicles, IDIQs, BPAs, or GSA Schedule positions and maintains no documented subcontractor role on other federal primes. Gunn Building PTY LTD's footprint is confined to construction and maintenance services for a single Department of State bureau, with no documented work for Department of Defense, civilian civilian-agency facilities, or multi-agency vehicles.
