Abstract: On March 12, 2023, an employee working for a concrete construction company was operating a hydraulic push pier system to raise a residential home foundation. One corner of the foundation had settled, and the company was tasked with raising it back up using the hydraulic system. The employee had dug several trenches alongside the foundation and was attempting to install the first push pier into the ground in one trench. The trench he was working in was 7.5 feet deep. The bottom bracket of the push pier was not installed per the manufacturer's instructions. The bracket should have been flush against the bottom corner of the base of the foundation. Instead, it was placed 6 inches away from the foundation wall. This allowed the top of the push pier bracket to pivot towards the wall. As the employee applied hydraulic pressure to the hydraulic ram the shear bolt broke. This caused part of the push pier to fly off and strike the employee in the head. The employee sustained a fractured skull and brain bleed and died in hospital.
