Foundation and electrical crews
under one company.

Cassidy’s history began with foundation work in Louisiana. Today, our Prairieville and Beaumont teams take on difficult foundation and marine projects, set transmission structures, and build and commission entire substations. Our crews support utilities, renewable energy facilities, industrial sites and data centers.
