About the company
Hartman-Cox Architects LLP is a for-profit architectural firm based in Washington, D.C., specializing in architectural and engineering services for federal agencies. Registered in the System for Award Management (SAM) since 2003, the firm provides comprehensive design, study, and construction administration services primarily to civilian federal institutions. The company's expertise focuses on architectural and engineering solutions for cultural and institutional facilities, with a strong presence in the Washington, D.C. metropolitan area.
The firm has secured multiple prime federal contract awards, predominantly from the Smithsonian Institution and the National Gallery of Art, covering a diverse range of architectural services. These contracts include video management system studies, facility infrastructure planning, roof replacements, building renovations, and specialized engineering assessments such as storm and sanitary sewer studies. Hartman-Cox Architects has performed work on projects including the Holt House assessment and demolition, green roof replacements, and fire alarm system upgrades. While most of their recent federal contracts were not set aside for specific business types, they do hold a small business set-aside Indefinite Delivery Indefinite Quantity (IDIQ) contract. The firm has also worked as a subcontractor for AECOM Technical Services, performing tasks like historic preservation surveys, construction administration, and design services for various federal projects.
Hartman-Cox Architects holds a single-award IDIQ contract with the Smithsonian Institution, awarded on February 14, 2023, with an ultimate completion date of February 13, 2033. This small business set-aside contract has a nominal potential value of one dollar but allows the firm to compete for task orders providing multi-discipline architectural and engineering design support for Smithsonian museums and facilities. Under this contract, they have already been awarded several task orders, including a $123,895.25 delivery order for a combination storm and sanitary sewer study. The contract enables Hartman-Cox Architects to continue providing specialized architectural and engineering services to support the Smithsonian Institution's ongoing facility infrastructure planning and maintenance efforts.
