Investigation abstract
At 11:30 a.m. on June 8, 2022, an employee was working as a laborer on a crew front and by four sets of axles and tires at the rear. The crew then placed concrete masonry units (blocking) with caps on the second through fourth piers from the front on either side up to the rear axles. To remove the axles and tires, the crew raised the rear end using 20-ton bottle jacks and placed temporary cribbing under the I-beams on each side, approximately 14-feet from the rear.
