Re: Union Station Train Shed Replacement
From TTC's Union Station Second Platform site:
TTC Union Subway Station – Second Platform
Sanitary Sewer Relocation
June 2006 to November 2007
The Toronto Transit Commission’s (TTC’s) Union subway station has experienced an outstanding increase in daily ridership usage since it opened in 1954. The station will undergo modifications that will include the addition of a second platform and improvements to the concourse level to increase public capacity, improve safety, pedestrian flow and service operations. This project is part of the revitalization of Toronto’s waterfront managed by the Toronto Waterfront Revitalization Corporation (TWRC).
Before work can start on the second platform, preliminary work involving the relocation of a sanitary box culvert (sewer) beneath Front Street is required.
This month, the TTC in conjunction with the TWRC will start a multi-stage construction project to relocate a 150m section of a 1050mm x 1575mm sewer presently situated beneath Front Street between York Street and Bay Street. This will involve construction of a new 900mm x 1800mm sewer beneath the moat area between Union Subway Station and Union Station Railway Terminal and connections to the existing sewer under Front Street at both the west and east limits. In addition, other connections to the new sewer will include smaller sanitary and storm sewers in the area. This work is scheduled for completion by November 2007.
WORK ZONES: will include,
In and near the Bay/Front intersection; in the moat area from Bay Street to the centre bridge of the Union Station Railway Terminal; various locations on Front Street including the eastbound curb lane opposite the main entrance to Union Station Railway Terminal.
WORK:
The work will generally consist of two methods of construction; cut and cover (excavate and backfill) and tunnelling. The cut and cover method will be used to construct an access shaft at the various work zone areas on Front and Bay Streets so that tunnelling can be done from those locations. Cut and cover will be the primary method of construction in the moat area.
All work zones at street level will be secured with hoarding and/or concrete barriers.
The first stage of sewer relocation will be the construction of an access shaft on Bay Street just south of Front Street. Followed by tunnelling from the shaft to the moat area and from the shaft to Front Street, slightly to the east of Bay Street. Construction of the sewer beneath the moat area or subsequent construction stages on Front Street will follow shortly thereafter.
TRAFFIC AND PARKING RESTRICTIONS:
At least one lane of traffic in each direction on Front Street and on Bay Street will be maintained during the stages of construction. In some instances, traffic turns will be restricted, i.e. northbound left-turn from Bay Street to Front Street during the first stage.
Curb lane parking will be reduced and/or restricted within and beyond the construction zones. Driveway access to businesses on Front Street will be maintained.
PEDESTRIAN ACCESS:
Access points to all buildings in the construction zones will be maintained. Access between BCE Place and the moat area will be maintained. Access between Union Subway Station and Union Railway Station Terminal via the moat will be maintained daily with some restrictions after 7:00 p.m., and after 11:00 p.m. on event nights at the Air Canada Centre and/or the Rogers Centre.
WORK HOURS:
Heavy construction work at street level will be largely confined to the hours of 7 a.m. to 7 p.m. on weekdays.
Occasionally, the contractor may need to work later in day or on weekends. In these instances, an effort will be made to keep noise levels to a minimum and limit the use of heavy equipment after 9 p.m.
Night work is essential on this project. The installation of hoarding and barricades, as well as some work in the moat and tunnelling will be conducted at night. The contractor will work in accordance with the City of Toronto noise By-law.
Construction update notices will be provided as work progresses.
