Investigation Summary

At approximately 7:30 to 8:00 a.m. on January 20, 2006, a six story building was under construction. Corrugated steel decking with wire meshing steel joist had been erected for the first floor. The joists were 24.75 ft long and 4 ft apart. This system did not need shoring. Steel erectors had burned and cut the steel joist so the cross supports would fit. This reduced the strength of the joist, a fact not noticed by the inspectors. The first concrete truck poured approximately 9 yards of concrete, approximately 3.5-in. thick. A second truck started pouring its load when an 8 ft wide and 24.75 ft long section of the deck collapsed. Employee's #1, #2 and #3 fell approximately 9 ft through the hole caused by the collapse. A large amount of concrete fell with them. Employee #1 hurt his back and shoulder and was hospitalized. Employee's #2 and #3 received bruises and lacerations on their arms.
