Our Engineering Design Firm’s History

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

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.
