Dive Brief: Following a series of recent construction worker deaths, New York City Department of Buildings Commissioner Melanie E. La Rocca this week mobilized teams of enforcement inspectors to perform safety sweeps of the city’s larger and more complex construction sites. While performing these "zero-tolerance" sweeps, DOB inspectors will issue enforcement actions if they observe any safety violations and will shut down sites if they find serious safety lapses, the city announced in a press release. Inspectors and community engagement teams will also be distributing "Worker Alert" safety information at construction sites on the dangers of worker falls. In the last two weeks, three construction workers in the city died in separate work-related incidents. Two of these fatal incidents were the result of worker falls, and all three incidents are under investigation.
