H2O Architects PTY LTD

H2O Architects PTY LTD, an Australian for-profit architectural and engineering services firm based in Collingwood, Victoria, operates exclusively as a prime contractor delivering specialized architectural design and engineering services to the U.S. Bureau of Overseas Building Operations with no set-aside designations across its federal footprint.

The vendor's customer base is entirely concentrated with the Department of State Bureau of Overseas Building Operations, which accounts for all four recent awards and the full $109 thousand in combined potential value. H2O Architects' work for OBO centers on architectural and engineering services for U.S. diplomatic facilities, with recent projects including a $26,790.83 firm fixed-price purchase order awarded August 24, 2026, for architectural and engineering densification services at the U.S. Embassy in Melbourne, Australia (ultimate completion February 1, 2027); a $26,013.03 purchase order awarded September 7, 2025, for as-built drawings and architectural and engineering services (completed December 29, 2025); a $35,947.71 purchase order awarded August 4, 2024, for architect and engineering services (completed May 30, 2025); and a $20,129.45 purchase order awarded August 31, 2023, for architectural and engineering design services supporting Level 7 office refurbishment (completed March 30, 2024). All work is performed in Australia under firm fixed-price structures. The vendor has recorded one award per year from 2023 through 2026, with no growth or contraction in award frequency. One award (combined potential value $27 thousand) reaches ultimate completion within the next twenty-four months and will face recompete exposure in that window. H2O Architects has no subcontracting footprint in federal work; all four awards are direct prime delivery.
