The metal cage in the hole is called a trench box, designed to save lives by securing the sidewalls inside an excavation area and preventing cave-ins. OSHA requires the boxes in excavations of 5 feet or deeper. Colarusso and Delaware Engineering will be using this trench box quite a bit in the next few months.
The amount of diesel exhaust produced by the trucks and machinery necessary for this project is astounding -- a lung, brain and planet destroyer.
