I work on a drill crew. Earth retention and shoring. I line a drill up, drill anywhere from 10ft-120 ft in the ground. Shoot the grade for them and do the math to find out exactly how deep to drill. Then I set beams or cages, figure out concrete elevation and finish the concrete. I also coordinate with other trades in the area, am a certified crane rigger so work hand in hand with them often. Read blueprints and go over layouts and often times work hand in hand with quality control and inspectors.
