The Story

The Bay Adelaide Centre office tower in downtown Toronto is designed as a landmark signature tower. It makes a unique and lasting architectural imprint on Toronto’s skyline with its distinctive rooftop silhouette. The impressive 51-storey office tower contains over 1,528,000 square feet of rentable, Class A office space. There is over 10,400 square feet of below grade retail space that links this complex to the extensive downtown concourse network. Three levels of existing below grade parking provides space for approximately 1,100 vehicles.

Brookfield Properties, EllisDon and Sota Glazing Inc. worked together to establish quality standards for the exterior curtainwall, budget, logistical planning, scheduling and details. Once these aspects were approved by Brookfield Properties and EllisDon, we contracted with Sota Glazing Inc. to secure the delivery of the product to meet the fast-paced schedule. EllisDon was also challenged with the restoration of the historical façade at Bay and Temperance Street. EllisDon determined that one of the two original buildings on the site would have two exterior walls removed, refurbished and reinstalled with new details. This process ensured that there was no compromise between the interfaces of the historical façade, new curtainwall and storefront exterior wall systems.

The Bay Adelaide tunnel is one of Toronto’s newest additions to the downtown pedestrian PATH system. The tunnel is 20-metres long by six metres wide, connecting Scotia Plaza to the Bay Adelaide Centre. Construction included drilling 29 piles and temporary support of many utility duct banks. The project also included the removal and replacement of a fully operational high-level city sewer interceptor, and the re-routing of another adjacent city sewer. The majority of work was completed during the day, and support beams and decking were installed to keep Adelaide Street open to the public while trades continued working. Communications was important on this project. The team established a divisional approach in the organizational chart to ensure we streamlined the process of information, reporting and red flagging of any issues that may have arisen on the project. The focus was on the use of site materials and the execution of manpower. Through this approach, the team members divided and conquered the challenges as they arose. We allowed each team member to do their own tasks and report to their superiors, effectively ensuring that the team communicated productively and responsibly to one and other.

This was the fruition of proper and thorough planning. We were committed to deliver.
