About DJB Contracting Inc.
DJB Contracting Inc. is a minority-owned, for-profit small business registered in SAM.gov since 2001, specializing in roofing, building envelope, and waterproofing services for federal agencies. As an Asian-Pacific American owned Subchapter S Corporation, the company has established itself as a reliable contractor primarily serving government institutions. The company's core competencies center on construction and renovation services, with a particular focus on roof replacement, repair, window and door installations, and building envelope improvements for federal facilities.
The majority of DJB Contracting Inc.'s federal contract awards have been with the Smithsonian Institution, encompassing a wide range of projects across multiple Smithsonian facilities including the National Zoo, Smithsonian Conservation Biology Institute, and various museums in Washington, D.C. These contracts, typically firm-fixed-price delivery orders, have ranged from small-scale repairs like installing roof drains and resealing counters to extensive renovation projects such as the $11.3 million modernization of the New Executive Office Building's 6th and 7th floors. The contracts have not been consistently set aside for specific business types, though the company has benefited from its minority-owned business status. In addition to prime contracts, DJB has also performed subcontract work for firms like Signature Renovations LLC and EG Management Services, Inc., demonstrating versatility in project execution across different governmental and institutional contexts.
