Subway Construction Activities at York University - Construction resumes on two of five construction sites

October 31, 2011

Subway construction was halted on the York University campus following a fatal accident on October 11, 2011. The accident site, directly north of the Schulich Building, remains closed under order of the Ministry of Labour (MoL). The four other subway construction sites on the campus were voluntarily closed by the contractor. The TTC, its contractor and the University have agreed upon a plan to resume construction on two of the five subway construction sites.

Construction will resume Tuesday, November 1, 2011, at the site on the southeast corner of Steeles Avenue West and Northwest Gate and at a second site south of The Pond Road, west of Keele Street. These two sites are those circled on the map below.

Since the accident, the TTC and its contractor have further reviewed safety plans and work methods for all sites on campus. The TTC is satisfied that all necessary safety protocols are in place to allow construction to resume on these two sites.

The TTC, its contractor and the University are reviewing plans and discussing resumption of work on the remaining three subway construction sites.

Steeles West Construction Site:

Work at the Steeles West construction site will involve the continuation of assembly and testing of the first tunnel boring machine (TBM) within the launch shaft. A crane, that is currently at the site, will be used to lower TBM components and materials into the launch shaft.

After a thorough review, and in consultation with the contractor, the TTC is confident that construction work at the tunnel launch site can safely resume.

The Pond Road Construction Site:

Work at The Pond Road construction site involves construction of a deep shaft, to the depth of the to-beconstructed  subway tunnels. The shaft is constructed in two stages, the first of which is drilling piles for the walls of the shaft. Nearly fifty percent of the pile drilling is completed for the shaft at this site. The drilling machine that is currently on site will be used to complete this work. Once the piling is complete, the second stage, excavation of the shaft, will begin.

The TTC and its contractor have further reviewed the safety plan and work methods for this site. The TTC is confident that construction work at this site can safely resume.
