Chevron Phillips Chemical, LP USCG Petrochemicals Ethylene


Cajun was contracted to install augered cast-in-place (ACIP) piling for Chevron Phillips’ U.S. Gulf Coast (USGC) Ethylene project in Baytown, TX. The completed, world scale ethane cracker will produce up to 1.5 million metric tons/year (3.3 billion pounds/year) and will be part of a $5 billion investment in ethane and ethylene derivative facilities in the U.S. Gulf Coast region. Cajun’s scope of work initially consisted of auger cast pile installation, but eventually grew to include sheet piles and drilled piers.


  • 100% of the work was self-performed by merit shop labor, trained and vested into Cajun’s top-performing, “safety-above-all” workforce.
  • Project won the 2015 Cajun President’s award.
