Abstract: On October 17, 2005, Employee #1 and six coworkers, all with Skanska USA Buildings, Inc., were pouring and finishing concrete on the second floor of a 45-story building under construction. At approximately 6:10 a.m., the workers began pouring concrete from the east side of the tower at table "G" and worked west to table "C" and "E". At approximately 9:10 a.m., after they had finished pouring the north side of table "C" to the centerline and had begun pouring from the east side of table "C" towards the centerline, table "C" began to fall, and table "E" fell shortly thereafter. Employee #1, who was working on the south end of table "C" on a walkway, fell with the table and slid to the end of the walkway. He was hospitalized at University Medical Center for neck and back injuries. The six coworkers either jumped onto columns or were caught by the rebar matting; all either self-rescued or were assisted off the table by personnel on site, and sustained minor injuries.
