The 1950's saw rapid growth into the private sector, with projects in the retail, banking, tenant improvement and emerging aerospace industries.  This time period also marked the addition of the third generation of Bingham employees to join the company, William Bingham Jr. and Mark Bingham.

The 1960's and 1970's were a time of change and diversity due to recessions and economic turmoil. To better serve its clients, Bingham Construction branched out into different fields including surveying, engineering, cabinetry, and concrete. The 1980's marked the end of an era the passing of Richard Bingham and William Bingham Sr.

"Our relationship has been exceedingly pleasant. We have a high respect for your ability and integrity. We are happy to recommend you most highly to any firm with whom you contemplate doing business."

G. K. Cunningham, Bank of America, January 27, 1958
