SHEFFIELD CONSTRUCTION, L.L.C.

Sheffield Construction, L.L.C. specializes in the renovation and adaptive reuse of commercial and institutional buildings, with a demonstrated focus on mission-critical defense infrastructure. The company delivers turnkey construction services for federal facilities requiring precise modifications to support evolving operational needs, including the retrofitting of existing structures to accommodate advanced military training and maintenance systems. Their technical expertise encompasses structural modifications, mechanical and electrical system upgrades, compliance with UFC and GSA standards, and coordination of complex logistics within active military installations. A key differentiator is their ability to execute sensitive renovations under stringent security and operational constraints, ensuring minimal disruption to ongoing military activities while maintaining full compliance with DoD facility requirements. The contractor has established a direct working relationship with the Department of Defense, delivering construction services tailored to U.S. Army installations. Their work at Fort Sill, Oklahoma, involved the transformation of Building 1503 to support the NMESIS training and maintenance mission—indicating experience with defense-specific technical specifications, weapon system integration environments, and military facility modernization protocols. This suggests a pattern of engagement with Army garrison construction offices and installation engineering commands, where precision, schedule adherence, and security compliance are paramount. Sheffield Construction’s primary industry focus is NAICS 236220, which encompasses the construction and renovation of non-residential buildings used for public, educational, and defense purposes. Their specialization lies in institutional building upgrades within the defense sector, positioning them as a niche provider for military facility modernization rather than general commercial construction. They serve a highly specialized segment of the federal construction market where functional reconfiguration of legacy structures is required to meet new operational mandates. As a Women-Owned Small Business certified under the SBA’s 8(a) and WOSB programs, Sheffield Construction leverages federal procurement preferences to compete for targeted defense construction opportunities. Based in Lawton, Oklahoma, the company maintains a localized presence near key military installations, enabling responsive project execution and deep familiarity with regional infrastructure demands and regulatory environments.
