City and other officials are investigating why a crane's steel load hit and shattered windows on the 45th and 46th floors of 4 World Trade Center on June 27th. There were no injuries, said a spokesman at the FDNY, which received the call about the incident at 11:30 a.m. Tishman Construction, the CM on the 72-story tower, says it has suspended steel lifts pending the investigation, is inspecting the entire facade of the building and reviewing protocols for evaluating weather conditions.
"A sudden gust of wind caused a steel load to impact a curtain wall panel on the south side of tower 4," a Tishman spokesman said in a statement. This resulted in glass falling onto Liberty St., which was closed at the time and is protected by a construction shed, he said.
