Company History

Since its founding in 1996, CSI Engineering LLC has focused on working with general and mechanical contractors to develop coordination drawings, as-built drawings and small-scale design-build projects.

Originally located in Strafford, NH, CSI Engineering has grown over the past fifteen years – in 2007 we opened a second office conveniently located in Saugus, MA, and expanded our capabilities to provide full Mechanical, Electrical, Plumbing and Fire Protection Engineering services to architects, contractors, industrial clients and municipalities. As of October 2012, CSI’s original office will be moving from Strafford, NH to Portsmouth, NH to fully service the state in a more convenient location. Never forgetting our origins, we continue to provide our engineering expertise in the development of coordination drawings and as-built drawings as needed by our valued clients.

With the addition of our Saugus, MA office to our new Portsmouth, NH office, CSI Engineering has the capabilities to fully service the New England Region. Our staff is highly experienced, having 60+ years of combined experience in the industry, and is dedicated to provide the highest quality of engineering services that our customers deserve and have become accustomed to.
