York University Site Preparations for Subway Tunnel and Station Construction

May 10, 2011

Construction Stage 1

Starting the week of May 8th, the tunnel contractor OHL/FCC will begin site preparatory works in the Harry W. Arthurs Common, near the Accolade East Building and the Schulich School of Business to enable future tunnel construction through this part of the campus by the Tunnel Boring Machines (TBMs) now known as Yorkie & Torkie.

This first stage of work includes preparation for the excavation, utility diversions, and building protection. Initial activities will include tree and landscape removals, installation of hoarding, minor utility relocation as well as contractor staging and site set up. The contractor will be installing hoarding across the north edge and partial east edge of the Schulich School of Business, within the south east end of the Common, across from the Accolade East Building.

Traffic Impacts and Pedestrian Safety

There will be intermittent lane restrictions on Ian Macdonald Blvd and York Blvd for site preparations. Traffic control personnel will be on campus to facilitate the safe movement of pedestrian and vehicle traffic around construction work areas. All current roads will remain open and operational during this time.

Construction updates will be provided as required through the first stage of construction. A detailed update will be provided for the all subsequent stages, in advance of the work.
