PCL continues to make steady progress on the first mass timber, net zero carbon emissions institutional building of its kind in Ontario.

Toronto, Ontario (April 19, 2023) – PCL and Limberlost Place partners are celebrating a significant construction milestone at George Brown College’s Limberlost Place with the installation of a two-story mass timber pedestrian bridge that was erected 65 feet above street level, connecting level five of Limberlost Place to level six of the college’s Daphne Cockwell Centre for Health Sciences.

Installation of the bridge included prefabricating individual cross-laminated timber pieces at an off-site location before being shipped and built on site. After four days of assembly, the team executed a complex and intricate one-day lift to install the structure. 

“Thank you to all of our partners, consultants, and extraordinary tradespeople who have been integral in achieving this significant milestone. This accomplishment truly showcases the exemplary level of skill, and patience it takes to ensure everything goes according to plan,” says Myke Badry, PCL Toronto’s district manager. “Congratulations to the entire project team as we move one step closer to the completion of this revolutionary project that is setting a precedent in mass timber construction.”

“It was incredibly exciting to witness the installation of the mass timber pedestrian bridge at Limberlost Place,” says Nerys Rau, GBC’s Project Director for Limberlost Place. “It was really impressive to see the placement done with such methodical precision.”

Designed by Acton Ostry Architects and Moriyama Teshima Architects, Limberlost Place is a tall wood, net zero carbon emissions building and PCL’s largest mass timber project to date. Home to George Brown College’s School of Architectural Studies, the School of Computer Technology and the Brookfield Sustainability Institute, students will learn in and from this innovative and future-proof facility. The 10-storey building is GBC’s newest addition to Waterfront Campus; Limberlost Place is expected to be completed by the fall of 2024 and will open for classes in January 2025.
