DOUBLEDAY ENGINEERING LLC

Doubladay Engineering LLC specializes in mission-critical facility infrastructure services for federal agencies, with deep expertise in roofing systems, plumbing, heating, air-conditioning, and fire detection and suppression system installation. The contractor delivers turnkey construction and maintenance solutions tailored to high-security and remote government facilities, including precise repair and deobligation management for complex contractual modifications. Their technical proficiency spans commercial-grade HVAC integration, waterproofing and structural roofing repairs, and code-compliant fire safety system deployment—particularly in challenging environments such as maritime installations and diplomatic outposts. A key differentiator is their ability to execute precision work under strict compliance protocols while managing close-out procedures and lifecycle adjustments for federal assets. The company maintains a focused presence with the Department of State, Department of Justice, and Department of the Interior, delivering facility resilience upgrades including fleet maintenance support, roofing restoration, and fire suppression system modifications. Their engagements reflect a pattern of responsive, mission-aligned work at sensitive or geographically isolated sites, where reliability and regulatory adherence are paramount. These agencies consistently rely on the contractor for time-sensitive, low-disruption infrastructure interventions that support operational continuity. Doubladay Engineering operates primarily within NAICS 238160 (roofing contractors), 238220 (plumbing, heating, and air-conditioning contractors), and 921190 (other general government support), positioning itself as a niche provider of integrated building systems services for federal facilities. Their market focus is on mission-support infrastructure rather than new construction, emphasizing retrofit, repair, and compliance-driven upgrades in federal and diplomatic environments. As a Woman-Owned Business certified under the 8(a) program, Doubladay Engineering LLC is structured as a small business entity based in Coral Gables, Florida, with a strategic footprint in federal contracting markets requiring agility, regulatory precision, and on-site responsiveness. Their certification enhances access to targeted set-aside opportunities while reinforcing commitment to diversity in federal supply chains.
