Safety experts studying recent accidents, focus on the hazards associated with concrete work. A number of concrete accidents involving shoring and formwork in the 1980s is noted. Stability during a pour is critical. Inexperienced contractors may not know how to avoid creating unbalanced loads. In Maryland, a 100-ft highway overpass collapsed on the Baltimore-Washington Parkway, and the roughly 20-ft-high falsework towers that supported the overpass may have been the cause. The bottom flanges of the beams rested on hardwod blocks that sat on concrete footings. The complex load chain of the falsework and the wood blocks were causes for concern. In California. lack of bracing for the formwork's shoring could have been the cause in a fatal garage deck collapse in West Hollywood.
