Mcdonald Construction Services, Inc.

Mcdonald Construction Services, Inc., doing business as MC Donald Construction Services Inc., is a for-profit Subchapter S corporation based in Fort Walton Beach, Florida, that operates as a prime contractor delivering HVAC equipment, chiller installation and maintenance, and mechanical systems work to the Department of Defense. The vendor competes in full-and-open competitions with no set-aside posture; recent prime work is concentrated in building infrastructure and equipment maintenance rather than designated small-business reserves.

The vendor's customer concentration centers on defense: the Department of the Air Force accounts for 30 awards and the Department of the Navy for 25 awards, together representing 73% of total awards by count. The Air Force Materiel Command Test Center drives most of the recent potential value with six awards totaling $1.2 million combined potential value, including a $460,228 firm fixed-price definitive contract for GWEF Temporary Chiller Follow-On work at Eglin Air Force Base awarded May 14, 2025, and a $517,305 purchase order for temporary chiller equipment also at Eglin, awarded May 13, 2024. The Air Force Materiel Command itself carries four awards worth $233 thousand in combined potential value. Mcdonald operates under five distinct indefinite delivery IDCs, with the largest vehicle (N6246783C0256) anchoring four task orders.

The vendor's capability portfolio is narrowly defined around HVAC, refrigeration, and air-conditioning equipment and services — maintenance, repair, installation, and rental of cooling and mechanical systems for military facilities. Top NAICS and PSC categories reflect this focus: Plumbing, Heating, and Air-Conditioning Contractors; Maintenance-Repair-Alteration of Miscellaneous Buildings; and Refrigeration and Air-Conditioning Equipment Maintenance and Lease. Total awards across ninety contracts and sub-awards carry $1.4 million combined potential value, though combined dollars obligated reached $16.5 million — a signal of a mature vendor with a long history of small, recurring facility maintenance orders rather than large capital projects. Activity is sparse in recent years (three awards in 2024, one in 2025), reflecting the cyclical nature of military facility maintenance and equipment replacement. In its minimal subcontractor role, Mcdonald performs HVAC services and mechanical system installation under Aktarius LLC and Dawson Enterprises, Inc.
