MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC

MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC specializes in commercial and institutional building construction, highway and bridge infrastructure, and mechanical systems rehabilitation for federal facilities. The contractor delivers full-cycle construction services including structural upgrades, drainage and erosion control, HVAC system replacements, and road rehabilitation on sensitive government sites. Their technical expertise spans design-build delivery, facility modernization, and civil works execution under strict federal compliance standards, with demonstrated experience in historic site preservation and mission-critical infrastructure renewal. A key differentiator is their ability to execute complex, multi-trade projects—integrating structural, mechanical, and civil elements—on constrained federal properties while maintaining operational continuity. The company maintains consistent engagement with the Department of Defense, General Services Administration, and Department of Agriculture, performing facility upgrades, infrastructure rehabilitation, and site development on military bases, federal office campuses, and national park lands. For the DoD, they deliver mechanical system replacements and building modernizations; for GSA, they execute design-build solutions for environmental resilience; and for the USDA, they focus on rural road and access infrastructure in forest service districts. Their relationships reflect a pattern of repeat work on mission-critical, low-disruption projects requiring precision and regulatory adherence. Their primary industry focus is on NAICS 236220 (commercial and institutional construction), 237310 (highway and bridge construction), and 238220 (plumbing, heating, and air-conditioning), positioning them as a specialty contractor for integrated federal infrastructure projects. They operate at the intersection of civil works and building systems, serving agencies with aging facilities requiring holistic renovation rather than isolated trades. As a small business structured as a 2L entity based in Washington, DC, MCKENZIE CONSTRUCTION has no federal certifications but maintains a focused geographic footprint centered on federal contract execution across the eastern U.S., with a proven track record in delivering high-compliance, low-impact construction services to sensitive federal installations.
