Mckenzie Construction & Site Development LLC

Mckenzie Construction & Site Development LLC, a Black American-owned, minority-owned small disadvantaged business certified under the SBA 8(a) Program, delivers design-build construction, facility rehabilitation, and infrastructure maintenance services to federal agencies exclusively as a prime contractor on total small business set-asides under the Great American Outdoors Act MATOC framework. Based in Washington, DC, the company operates as a for-profit Subchapter S corporation and has built its entire recent federal portfolio on two large multiple-award task order contracts (MATOCs) with the Department of Interior Fish and Wildlife Service, each carrying a $250 million ceiling and authorizing work across all U.S. states and territories on federal properties managed by the Department of Interior and the U.S. Forest Service.

Mckenzie's capability portfolio centers on design-build construction, repairs, alterations, and deferred maintenance elimination on federal facilities. Concrete recent work includes a $9.8 million delivery order from the U.S. Forest Service Region 8 (awarded June 1, 2026, with completion November 30, 2026) for disaster recovery and heavy maintenance of roads on the Davy Crockett and Sam Houston National Forests in Texas; a $7 million delivery order from the Department of Interior Fish and Wildlife Service Region 1 (awarded September 22, 2023) to construct a replacement fish health center laboratory at Warm Springs National Fish Hatchery in Oregon; a $2.1 million delivery order from the Forest Service Southern Research Station (awarded June 5, 2023) for the Athens South Building energy improvements and deferred maintenance elimination project in Georgia; and a $1.4 million delivery order from the Department of Interior Northeast Region (awarded September 27, 2022) to convert Elkwallow Springs to wells and replace the water distribution system in Luray, Virginia. The company also executes smaller task orders for guardrail repairs at National Capital Parks, stone barrier rehabilitation at Shenandoah National Park, towpath resurfacing at the Chesapeake and Ohio Canal National Historical Park, and building rehabilitations across the National Park Service portfolio, with individual task order values ranging from approximately $124,000 to $6.7 million.

The company's customer base is heavily concentrated among Department of Interior agencies, which account for approximately 98% of the combined potential value across all awards. The Department of Interior Fish and Wildlife Service alone anchors $500.5 million in potential value across two MATOC IDVs and subordinate task orders; the Department of Agriculture Forest Service R8-Southern Region contributes $10.9 million across three awards; and the Department of Interior National Park Service Northeast Region and National Office contribute $2.8 million and $1.9 million respectively. GSA Public Buildings Service National Capital Region holds seven awards totaling $1.7 million, primarily for facility repairs in the Washington, DC area. Mckenzie operates exclusively through the Great American Outdoors Act MATOC vehicle, which generated 11 task orders worth $26.6 million in combined potential value.

Activity has remained modest and flat in recent years — four awards in both 2022 and 2023, three in 2024, one in 2025, and one awarded in 2026 (as of the summary date). Two awards carrying combined potential value of $10.6 million reach ultimate completion within the next twenty-four months, triggering recompete exposure. SCI-reported service contract invoicing totaled $3.2 million in FY2024 against 1.7 FTEs delivered to the federal government; no SCI-reportable revenue appears for FY2022 or FY2023 in the dataset. The company reports a median government-paid hourly rate of $597.07 per hour across prime contracts, with the 90th percentile reaching $2,127.95 per hour, and delivers work exclusively with its own staff — zero sub-hours share across prime SCI records. The company has never pursued subcontractor arrangements and operates as a 100% prime contractor footprint. Mckenzie is structurally positioned as a child entity under a parent company also named Mckenzie Construction & Site Development LLC, though the source provides no subsidiary differentiation in capability or operating scope.
