Firm History:

Structural Engineering Associates, Inc. was founded by Jesse S. Covarrubias, P.E. in September 1976. After gaining valuable bridge design and construction experience working for Caltrans (California Dept. of Transportation) and later for the TxDOT Bridge Division, Jesse worked for a consultant, designing a variety of structures. With that foundation, Jesse was ready to start his own firm, and so began SEA.
SEA exists not only to design outstanding quality structures, but to positively impact the communities we serve.
