Mellor Contracting & Supply, LLC, doing business as Mellor Contracting, is a minority-owned, woman-owned small business headquartered in Ambler, Pennsylvania, that has been registered in the System for Award Management (SAM.gov) since April 2011. The company specializes in comprehensive mechanical services and infrastructure maintenance for federal government agencies, with a demonstrated focus on supporting military installations. Mellor Contracting's expertise spans HVAC systems, boiler and chiller repairs, plumbing and utilities maintenance, fire suppression system repairs, electrical work, and related facility infrastructure upgrades essential to maintaining operational readiness at military bases.
Mellor Contracting's federal contract portfolio demonstrates extensive engagement with the U.S. Air Force's Air Mobility Command, serving as a primary contractor for mechanical and infrastructure services at Joint Base McGuire-Dix-Lakehurst in New Jersey. The company holds a significant $60 million multiple-award indefinite delivery/indefinite quantity (IDIQ) contract with Air Mobility Command that was set aside for small businesses, under which it has executed numerous firm fixed-price delivery orders. Recent contract awards include specialized work such as HVAC system replacements across multiple buildings (ranging from $10,000 to $320,000+ in individual orders), boiler and chiller replacements and repairs, hot water tank and piping removal, fire suppression system repairs, heat pump mini-split installations, building automation control upgrades with BACnet functionality, water system surveys, chemical pot feeder installations, and utilities infrastructure maintenance including lift station repairs and cooling tower repairs. The company has also performed work for the U.S. Army Forces Command (FORSCOM) and Naval Air Warfare Center on duct cleaning and related services. Most contract awards carry no socioeconomic set-aside designation despite the company's minority-owned and woman-owned status, reflecting its competitive capability to win open competitions. Project completion dates have ranged from urgent turnarounds to extended periods, with several contracts receiving time extensions and modifications for additional in-scope work or unforeseen conditions, demonstrating the contractor's ability to manage complex, long-duration infrastructure projects across multiple military facilities.
