"Project Overview and Deliverables
Union Station is the largest transportation hub in the country, handling 65 million passengers annually and expected to double by 2031. It is currently undergoing redevelopment and revitalization in order to accommodate the increasing commuter volumes and turn the landmark facility into a transportation, community hub and destination.
This includes excavation for a new retail concourse level, construction of two new concourses for GO Transit, restoration of the VIA concourse and renovations to the West Wing and Centre Block and exterior restoration of the building.
Project Status
Stage 1 -
Stage 1 is fundamentally complete except for minor deficiencies being rectified and closeout documentation. Key milestones reached and components completed on Stage 1 and the North West PATH include:
VIA Elements – Panorama Lounge, York West Teamway Catering space, East Concourse offices, baggage handling system, heritage washrooms, office space and Great Hall ticket offices.
York West Concourse – base building fit-up work including stairs / elevators to platforms, life safety systems, loading docks and access/egress through Air Canada Centre, Maple Leaf Square and Telus building tunnels with York Concourse strata sold to and occupied by Metrolinx.
West Wing - Floors 2 through 4 complete, strata sold to and occupied by Metrolinx. Structural Support Column Replacement (Stage 1) is complete. Electrical systems completed including installation, commissioning and operation of main and emergency power, lighting and lighting control, safety/security and communications systems. Mechanical systems completed including installation, commissioning and operation of HVAC, fire protection, plumbing, building automation and mechanical equipment systems. Exterior heritage façade restoration including roof of West, East Wings and Centre Block.
NW Path Phase 1 complete and open to the public in April 2015. This connects the northwest corner of Union Station across Front Street to the northwest corner of Front and York Street. Stage 1 base building Retail Concourse beneath York and VIA Concourses is complete. Retail areas are released to the Head Lessee for installation of fixtures and occupancy by tenants. Some retail operations are expected to open by Q4 2017.
Stage 2/3
Exterior restoration of the East Wing is 99% complete.
Great Hall Restoration: East and West arches, including windows, north wall and ceiling cleaning complete, south wall 90% complete.
VIA Concourse restoration is 75% complete.
Front Street West Moat: Moat Installation is 80% complete.
Front Street East Moat: Moat Installation is 40% complete.
East Wing ground floor over 80% complete.
Bay Concourse/Retail: Excavation 100% complete; Structural column replacements completed; 100% of new Bay Concourse suspended slab completed; 80% of slab on grade completed.
Remainder of Stage 2/3 which includes the Bay Concourse is expected to be completed by mid-late 2018. This will trigger the turnover of the Bay Concourse to Metrolinx to facilitate the fit out and completion of the concourse for future public access.
Project Challenges
The project has experienced challenges due to a number of factors, including found site conditions such as heritage, environmental elements including designated substances, and performance issues with the General Contractor/Construction Manager on Stage 1, the prime consultant, and certain subcontractors.
In addition, development of the stage 2/3 schedule, with the inclusion of transfers of work from Stage 1, has created further challenges.
To mitigate risks, project teams have responded with value engineering, constructability changes, challenging of tender results, retendering, minor scope adjustments, and consideration of different construction methodologies.
The project has encountered pressures, to both budget and schedule, due to coordination of capital projects at Union Station with other stakeholders.
The Union Station Revitalization project involves concurrent projects managed by Metrolinx and the City of Toronto respectively. Completion of the City's base building work in the Bay Concourse is dependent on Metrolinx's completion of the vertical access work in the area. Because Metrolinx is managing additional project requirements for its own Union station platform project, this is resulting in delays for the City's work. Based on information to date and the resequencing of the Metrolinx work that is required, a project delay of approximately six months is anticipated, taking substantial completion of the City's Union Station Revitalization project to the end of 2018. There will be corresponding budget impacts as a result of this delay and other inherent project risks. Both organizations are committed to working together to mitigate both schedule and budget impacts. City staff will report to Council with a comprehensive update once Metrolinx confirms its adjusted work schedule and sequencing.
