BERKELEY BUILDING COMPANY

Berkeley Building Company specializes in the construction, maintenance, and repair of mission-critical commercial and institutional facilities, with deep expertise in mechanical systems integration for federal research environments. Their core capabilities include the installation, repair, and modernization of heating, ventilation, and air conditioning (HVAC) systems, plumbing infrastructure, and building envelope components, particularly in demanding thermal and environmental conditions. They deliver comprehensive facilities support services, including annual maintenance task orders and targeted mechanical repairs for laboratories and operational buildings, demonstrating proficiency in working within constrained, high-security federal sites. Their work on refrigeration innovation projects and boiler systems indicates advanced technical fluency in cryogenic and climate-controlled environments, with a focus on reliability and operational continuity. The company maintains a consistent relationship with the Department of Defense, delivering construction and maintenance services for research facilities under the U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) and other defense installations. Their work supports defense science and engineering missions, particularly in extreme climate zones, where facility integrity directly impacts experimental validity and personnel safety. Industry focus centers on NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors) and 236220 (Commercial and Institutional Building Construction), with secondary engagement in facilities support services (561210) and specialized research support (541715). This positions them as a niche provider for federal science and defense infrastructure, where precision mechanical systems and building performance are paramount. Berkeley Building Company is a small business structured as a 2L entity, headquartered in Reading, Massachusetts. While no government certifications are listed, their consistent performance on complex DoD projects reflects established operational credibility within the federal construction and facilities maintenance market. Their geographic presence supports regional defense and research infrastructure needs with responsive, on-site technical execution.
