On Thursday, a worker named Juan Chonillo fell to his death from a Fortis Property Group project in lower Manhattan. He was employed by a non-union firm called SSC High Rise Construction. Hours later, a 45-year-old worker employer by union subcontractor EJ Electric fell to his death at Brookfield Property's Manhattan West—the second fatality on the site in four months. The Department of Buildings said Monday that contractors in both instances have supplied the administration with the required data.

The legislation, sponsored by City Councilman Ben Kallos, was among a suite of construction bills passed earlier this year. Lawmakers are set to pass a controversial construction training bill on Wednesday
