future-oriented
Our History
Founded in 2009, CAS was built on a commitment to safety, teamwork, quality, and integrity. What began as a small automation firm providing in-house and in-plant services to local industries in the Golden Triangle quickly gained momentum. By 2011, CAS expanded its team and service offerings to include instrumentation, electrical engineering, and design. Continued growth led to the purchase of its current 30,000-square-foot headquarters in 2015, located on four acres at 2295 Delaware Street in Beaumont, Texas. Today, CAS is a multi-discipline, full-service engineering company with Professional Engineers delivering fully integrated Engineering, Procurement and (EPC) services—including Front End Engineering Design (FEED) studies—to the petrochemical market. CAS is widely recognized as one of the top preferred engineering firms in Southeast Texas.
