At approximately 7:15 a.m. on August 9, 2007, Employee #1 and a coworker were stripping the interior form work of a 15 ft long by 8 ft deep by 3 ft wide by 8 in. thick, type G-2 drainage inlet structure. They were doing this while the cement slurry backfill was being poured between the excavation wall and the north wall of the inlet structure. Two trucks, each carrying 10 cubic yards of the slurry, had already poured in their contents. When the third truck pour was in progress, the north wall developed vertical cracks and pushed toward the south wall of the inlet structure, crushing Employee #1 against the south wall. He sustained numerous bodily injuries. The coworker was able to climb out safely. | |||||||
