U of T unveils plans for 14-storey mass timber project

The University of Toronto is set to build a 14-storey academic tower made of timber on its downtown Toronto campus – expected to be the tallest mass timber and concrete hybrid building in North America.

“There are a lot of compelling arguments for the use of wood,” says Gilbert Delgado, U of T’s chief of university planning, design and construction.

Recognizing the benefits of building with timber, the Ontario and federal governments are providing funding for buildings that use the material. U of T’s wood tower will be financed in part by those government subsidies, and through university funds and philanthropy, says Delgado.

The tower will be built above the Goldring Centre for High Performance Sport and will house a number of academic units, including Rotman Executive Programs, the Munk School of Global Affairs, the Faculty of Arts & Science’s Master in Mathematical Finance program, and the Faculty of Kinesiology & Physical Education.

U of T is working on the project with Patkau Architects of Vancouver in partnership with MacLennan Jaunkalns Miller Architects (MJMA) of Toronto and Blackwell Structural Engineers – all of whom worked together on the Goldring Centre, which opened in 2014.

The Goldring Centre was designed and built with the structural integrity to be the base for the tower so there will be no need to dig deeper in order to build the taller structure, says Ted Watson, a partner at MJMA.

“As part of that project we developed a structural base, a foundation, to put the future tower on top of,” he says. “We don’t have to go down into the ground and all of the mess and construction disruption that goes along with that – that work has been done.”

The tower was originally slated to be built using steel, but after becoming aware of government incentives and of research by members of the Faculty of Forestry, including the former dean Mohini Sain, the university decided to go with timber.

U of T’s new tower will be built with cross-laminated timber (CLT) – a method that allows producers to create larger, stronger wood pieces in more consistent dimensions. Many of the tower’s components will be manufactured offsite so by the time the pieces get to the construction site, they can be assembled easily, quickly and quietly, says Watson.

As part of the Ontario government’s tall wood building incentive program, the province has also established a Mass Timber Institute (MTI), bringing together organizations from across the province, including U of T and other academic institutions, to study the building practices and benefits of wood construction. MTI’s interim director is Anne Koven, an adjunct professor in the Faculty of Forestry.

“The Mass Timber Institute can really animate and excite people and promote building with wood,” she says.

The institute has an opportunity to study the construction and future benefits of U of T’s wood tower through all stages of its development, says Wright.

“We need to build these buildings as case studies to actually identify and deal with issues and people’s perceptions of wood building, in terms of design, construction, and the training of people who will actually build them,” he says.

U of T’s academic wood tower is still in the design phase of development, awaiting zoning changes to increase the height allowance for tall wood buildings. Construction could begin at the end of 2019.
