Cajun was contracted to drill and pour 81 EA 36” diameter drill shaft foundations ranging in depth from 10’-16’ deep and 6 EA 72” diameter x 31’ deep drill shaft foundations for a new substation.

Accomplishments

• Eliminated some anticipated costs drilling all the 36” diameter shafts using the dry drill method instead of the slurry drill method. We originally anticipated a third of the 36” drill shafts would need the slurry drill method.
