GNCB was founded in 1965 and traces its roots to the Old Saybrook branch of a Denver, Colorado firm established by Milo S. Ketchum. Mr. Ketchum was an internationally-known pioneer of thin shell concrete structures in the United States, a brilliant structural engineer, and an educator. GNCB was also instrumental in developing the Special Inspection (SI) Program in Connecticut which became the model for the current International Building Code.
