About General Mechanical Corporation
General Mechanical Corporation, doing business as GMC Construction, is a tribally-owned, minority-owned small disadvantaged business headquartered in Daytona Beach, Florida. The company is certified in the Small Business Administration's 8(a) Business Development Program, with certification valid through November 3, 2031, and maintains active registration in SAM.gov through October 7, 2026. GMC Construction specializes in construction, renovation, repair, and maintenance services for federal agencies, with particular expertise supporting critical national security space operations and border security infrastructure. The company has established a strong track record as a prime contractor with federal agencies, holding multiple indefinite delivery contracts and receiving delivery orders totaling millions of dollars across defense, civilian, and space agencies.
GMC Construction has provided a diverse range of construction and facilities services through federal contract awards, demonstrating expertise across multiple project types and geographic locations. The company has completed or is executing major definitive contracts including an $11.9 million dune restoration project at Naval Station Mayport awarded by Naval Facilities Engineering Command, an $8.43 million HVAC system replacement at Kennedy Space Center's logistics facility, an $8.34 million Naval Air Station Jacksonville Instrument Landing System infrastructure project awarded by Naval Air Systems Command, and a $7.1 million base facilities project in Atlantic Beach, Florida for Naval Facilities Engineering Command. GMC Construction has also performed specialized work including a $1.23 million hurricane repair project at Naval Station Pensacola, security installation services at a Department of Homeland Security Customs and Border Protection facility in McAllen, Texas, and holding cell door lock replacement at a CBP facility in Milwaukee, Wisconsin. Under the Air Force Space Command, the company has executed multiple hangar repair and renovation projects at Cape Canaveral Space Force Station and Patrick Space Force Base, including hangar repairs valued at $1.74 million for Hangar I, $1.44 million for Hangar Y second floor renovations, and $348,817 for Hangar AA repairs. Additional Air Force Space Command task orders have included road repairs ($1.75 million for South Hangar Road), GPS facility repairs ($715,440), and navigation marker replacements ($63,500), all performed at Cape Canaveral Space Force Station under the Space Coast MAC. GMC Construction also holds an indefinite delivery contract with the Department of Defense's Southwest Region for painting services, with delivery orders issued for painting work at various federal facilities. The majority of GMC Construction's awards have been designated as 8(a) sole source set-asides, recognizing the company's status as a certified small disadvantaged business, though several awards have utilized total small business set-asides or no set-aside designations.
General Mechanical Corporation holds two significant indefinite delivery contract vehicles. The primary vehicle is the Space Coast Multiple Award Construction Contract (Space Coast MAC), a $750 million multiple-award IDIQ awarded by the U.S. Air Force Space Command with an ordering period through October 31, 2031. Under this contract, GMC Construction has received over $7 million in delivery orders for maintenance, repair, and minor construction services across space operations installations in Florida, with task orders covering facility repairs, hangar renovations, road repairs, GPS facility maintenance, and design-build services. The Space Coast MAC supports critical infrastructure requirements for the Air Force's space launch activities and technical application programs, as well as facility needs for other agencies including NASA and Customs and Border Protection. Additionally, GMC Construction holds a single-award Indefinite Delivery Contract with the Department of Defense's Southwest Region for painting services, awarded on July 1, 2024, with a ceiling value of $1,459,629.33 and period of performance through June 30, 2027. This painting contract is designated as an 8(a) sole source award and has already generated two delivery orders: a seed task order valued at $25,653.07 for painting services in Sparta, Wisconsin, and a larger delivery order valued at $243,567.30 for painting buildings at the National Capital Operations Area, also based in Sparta, Wisconsin. Both delivery orders under the Southwest Region painting contract are structured as firm fixed-price awards with no additional set-aside designations, providing the Department of Defense with flexible procurement authority to issue painting-related task orders as requirements arise across its operational footprint.
