About the firm

CSI Engineering is an MEP/FP engineering design practice based in Portsmouth, New Hampshire. Founded in 1996, CSI Engineering began by supporting general and mechanical contractors with coordination drawings, as-built drawings, and design-build projects. In 2007, CSI Engineering expanded into full MEP/FP engineering services for architects, contractors, developers, municipalities, and the military. The three principal engineers are involved directly in every project, bringing construction-background perspective to building systems design. CSI Engineering's primary service area is New England, with completed projects extending to other US states and internationally.
