Values

Fabrication
Corrigan deploys a time-tested innovative construction process called the Corrigan Success Model that delivers the best cost by adding value at every step along the way. For example, Corrigan can fabricate and assemble piping modules and other sub-assemblies in its own shop, delivering greater efficiency, higher quality craftsmanship, and lower cost than assemblies made on the job site. Today it is the largest pipe fabrication operation in St. Louis.
