What We Do
CSI Engineering LLC has been in business since 1996 and offers consulting services in the following fields: HVAC, Electrical, Plumbing, Fire Protection, Commissioning, Mechanical and Electrical Systems Assessment, and Energy Studies.
CSI ENGINEERING IS THE COMPANY THAT WILL WORK HARD TO MAKE SURE THE PROJECTS ARE DONE CORRECTLY, ON TIME, AND ON BUDGET.
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. In October 2012, CSI’s original office moved 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 Portsmouth, NH office to our Saugus, MA office, CSI Engineering has the capabilities to fully service the New England Region. Our staff is highly experienced, having 100+ 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.
