Upon its founding in 1996, CSI Engineering LLC focused on working with with general and mechanical
contractors to develop coordination drawings, as-built drawings and small to large-scale design
CSI Engineering grew over the next 10 years and led to us expanding our capabilities in 2007 to now provide full Mechanical, Electrical, Plumbing and Fire Protection Engineering services to architects, contractors, developers and an array of public work including municipalities and the Military.
In October of 2012, CSI’s original office moved from Strafford, NH to Portsmouth, NH. We continue to provide our engineering expertise in building systems design drawings and as-built drawings as needed by our valued clients. With the office now in Portsmouth, the heart of the Seacoast, CSI Engineering has the capabilities to fully service the New England Region.
