Joint Meeting with ICRI & DVASE

Second Avenue Subway Tunnel Expansion Project

October 17, 2017

PROJECT ABSTRACT:

The Second Avenue Subway is the new line extending approximately 8.5 miles along Manhattan’s East Side from 125th Street in Upper Manhattan to Hanover Square Lower Manhattan. The first construction contract was awarded to S3 (Skanska, Schiavone and Shea Joint Venture) in March 2007, and now has been recently completed.

 

The project includes construction of a Launch Box for the tunnel boring machine (TBM) between 92nd Street and 95th Street and the bored tunnels from 63rd Street to 92nd Street. The Launch Box excavation is 55 to 65 feet deep, occupying the whole width of 2nd Avenue and is constructed by cut-and-cover method. The southern half of 96th Street Station is also constructed within the Launch Box excavation.

 

This presentation discusses the critical issues and construction constraints and challenges of the construction of the Launch Box and subsequently the Tunnel Boring Machine (TBM) work. These include the challenges of maintaining the traffic and utilities at 2nd Avenue while constructing the Launch Box, the support of excavation systems, construction sequence, TBM tunneling work, and finally the tunnel waterproofing and concrete tunnel liner work.
