Primoris Heavy Civil (formerly James Construction Group) has long standing history that dates back to the 1920’s, where it earned the reputation as one of the most well respected heavy civil contractors in the Gulf Coast region. In 2009, the company’s growth continued through a merger with Primoris Services Corporation, one of the largest companies listed in ENR’s Top 400 Contractors. With the bonding capacity and resources of the parent company, Primoris Heavy Civil has the potential to expand to an even larger role in the heavy civil and transportation industries in the coming years.

Primoris Heavy Civil is comprised of five operating units that include North Louisiana Operations, South Louisiana Operations, Texas Operations, HMA Paving Operations, and Concrete Paving Operations.
