Our History

Engineered to Last

In 1954, Irwin Arden opened a local mechanical and general contracting company in Providence, RI which he aptly named the Arden Engineering Company. Over 60 years later, the Arden namesake endures as we have evolved into a multi-faceted group of geographically diverse firms that together comprise the Arden Building Companies family. With general headquarters in Pawtucket, Rhode Island, we employ over 300 office and union craft personnel throughout RI, MA, and CT.

Arden Engineering Constructors, LLC

Arden Engineering Constructors is the direct product of the strategic evolution and expansion of what Irwin Arden began in 1954. Now located in the heart of Pawtucket, RI with an in-house prefabrication shop, 50 full-time office employees, and over 125 union craft personnel, we’ve become the largest mechanical contractor in Rhode Island. Specializing in the design, installation, and maintenance of mechanical HVAC, plumbing, and electrical systems, we work primarily in the healthcare, education, and industrial markets to ensure that your building is running safely and efficiently.

Rayco-Arden Electrical Division – In 2015, our electrical division expanded with the acquisition of Rayco Electrical Contractors of Providence, RI. This merger emphasizes our commitment to providing complete electrical design and construction services to the highly specialized medical, data center, and high-tech customer market.
