About the company
Carolle A Daniel, doing business as Dunbar Construction LLC, is a woman-owned sole proprietorship based in Brandywine, Maryland, that performs facility maintenance, repairs, and emergency construction services for the Smithsonian Institution as a prime contractor on small purchase orders, with no subcontracting activity.
The vendor holds a Woman Owned Small Business (WOSB) designation and operates exclusively under full-and-open competition — none of the 47 awards in the source carry a socioeconomic set-aside. Dunbar Construction competes on individual Firm Fixed Price purchase orders rather than on IDVs, GWACs, or BPAs. Work centers on commercial and institutional building construction (39 awards), maintenance and repair of miscellaneous equipment (15 awards), and office building maintenance (9 awards), with secondary exposure in HVAC, plumbing, and water/sewer line construction. Representative recent work includes a $25,681.30 purchase order awarded April 10, 2026 for facility services and maintenance at the Smithsonian's Natural History Building (running through September 30, 2026), a $12,320.17 emergency sewage replacement contract at the National Museum of Natural History completed in June 2024, a $9,121.00 handrail replacement at the Udvar-Hazy Center loading dock completed in June 2022, and a $7,128.46 Natural History Building maintenance order completed in November 2022.
Customer concentration is complete: the Smithsonian Institution accounts for all 47 awards and the full $484 thousand in combined potential value. Activity is sparse and episodic — eight awards in 2020, declining to one in each of 2024 and 2026, with only one award (valued at $26 thousand) facing ultimate completion inside the next twenty-four months. The vendor has no pipeline visibility beyond the immediate Smithsonian relationship and does not sub to other prime contractors. The footprint reflects a single-customer, purchase-order-based relationship anchored to facility operations and capital-repair work at Smithsonian properties in the greater Washington, D.C. area.
