The Second Avenue Subway project will be using a well established excavation technique called controlled blasting to excavate two access shafts at 69th Street and 72nd Street which will eventually be used as access points for the construction of the 72nd Street Station. We have used this technique at many of our projects in Manhattan.

Controlled blasting activities are scheduled to begin on or about February 8th, 2010.

The Fire Department of New York (FDNY) has approved a controlled blasting plan for the area of Second Avenue between 69th and 73rd Street which will be carried out in coordination with the MTA and S3 Tunnel Constructors. All blasting will be conducted under the direction and regulations of the FDNY. Blasting is permitted to take place during the approved Second Ave Subway working hours of 7 AM to 10 PM, although, every effort will be made to limit blasting to daylight hours.

Blasting Procedures

As required by New York State regulations, and monitored by FDNY, all explosive materials are delivered to and from the work site daily. Vibration and noise limits have been established by the MTA and the project designer. The vibration and noise readings will be monitored by the construction management team.

Please direct any questions or concerns to Marcus Book, Assistant Director, MTA NYC Transit Government and Community Relations at 646-252-2675 or Claudia Wilson at the work site at 212-792-9716.
