The Empire State Development Corp., which is overseeing the project, said work on the tower started in November. It is the last residential building at the Queens West development, located behind the landmark neon "Pepsi-Cola" sign near the East River waterfront. The building is slated to be completed in early 2014 but city officials could not say how long work will be shut down.
Engineers will examine the history of the crane involved in Wednesday's collapse as part of the investigation, including the equipment's maintenance and operation records.
The 2008 accidents led to new safety measures, including hiring more inspectors and expanding training requirements and inspection checklists.
