After construction crane collapses during Irma, regulations questioned

After three partial collapses of construction cranes during Hurricane Irma, officials are debating whether regulations should be tightened.

Two crane booms in Miami and one in Ft. Lauderdale collapsed during the storm, with no injuries reported. The equipment was supposed to be able to withstand 145 mph winds, but the highest gusts recorded in the area were 100 mph.

Any initiative to impose tougher regulations on cranes would be complex, with federal, state, and local authorities all having a hand in rulemaking and oversight. Cranes are regulated by the federal government’s Occupational Safety and Health Administration. Florida statute preempts cities from enforcing laws regulating cranes, but Miami does enforce codes and regulations on the construction and maintenance of buildings. The multiple authorities have some overlap when it comes to construction cranes, at least in theory.

Industry trade groups warn that new regulations should wait until more is known about what caused the collapses. All of the collapses occurred where cranes were set up at 300 feet high or higher, and there is limited data on wind speeds at those heights during the hurricane.

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
