Mayor Bill de Blasio announced new, citywide safety measures for cranes on Sunday, following Friday's deadly collapse in Lower Manhattan.
The new regulations will require crawler cranes to be placed in safety mode when winds reach 20 miles-per-hour.
That's lower than the previous standard by five miles-per-hour.
The mayor says there will also be a new task force dedicated to overseeing crane safety measures and regulations.
He says residents and business owners will also be notified whenever a crane is being lowered, or moved.
And work crews must ensure sidewalks are clear of pedestrians.
The mayor says the accident is a harrowing reminder that safety must come first.
"Friday's incident obviously is a warning we take very seriously we all know there's a construction boom going on in our city," the mayor said. "We value the work that's being done, we value what it means for our economy, we valued that jobs are being created. Nothing is more important than the safety of our people...There's no building that is worth a person's life."
The 565-foot long boom from Friday's crane collapse was broken into pieces and hauled away from Worth Street.
Some residents on the block are still without gas, after Con Edison shut it off as a precaution.
Three buildings in the area are still without running water.
Mayor de Blasio says the crane safety measures will take effect tomorrow.
