They estimated there was a very real chance the 26,000-pound boom, thrown over the back of its mast and dangling by frayed cables, would plummet—directly onto a gas main below, with unthinkable consequences.
Michael Alacha thought he was prepared for Superstorm Sandy. Days before the storm, the assistant commissioner for the Department of Buildings made sure the agency issued wind advisories, even going so far as to require crane users to inspect their machines to ensure they were shut down properly for high winds.
Still, on October 29 as Sandy blew in, the unthinkable happened. Winds near 100 mph buffeted a 1,000-ft-tall skyscraper under construction on Manhattan's West 57th Street, flipping over the jib of a tower crane like a wet noodle. Twenty six thousand pounds of limp steel, wire rope and other debris dangled precariously over midtown Manhattan.
Stationed at his office's emergency response center, Michael Alacha witnessed the event on television and raced to the scene. "My concern was the crane's connection to the building, specifically the top tie," Alacha recalls. "If that was compromised, with the storm still halfway through, the entire mast may have collapsed."
The noise and pressure from the wind was overwhelming. "I felt something fly by my eyes," Alacha recalls. "Seconds later, I realized they were my glasses."
In a few days, the crane was secure and nearby buildings re-opened. His quick thinking made a difference. The damaged rig is due to be replaced in March.
"I think Mike Alacha handled the situation very well," says Tim Lynch. "He kept a very calm head."
