I was on a major construction project that involved heavy machinery, equipment and a lot of man power. The site that was chosen for this project was unique as it was the former site of a massive steel mill. As was the case in the late 70's early 80's during the shutdown boom of the steel belt, the company simply closed the doors, demolished the building and put all of the rubble in the ground and capped it. Sweep it under the carpet right? On this job a contractor was using a hydraulic hammer bit on an excavator breaking apart all of the old rubble. Chipping away one-by-one it seemed like a task that was relatively safe, until one morning where it all changed.
