Tri-Phase Group was awarded the Ontario Line North Segment Project, a comprehensive initiative aimed at facilitating infrastructure improvements across multiple sites in Toronto, Ontario. The project entailed hazardous materials abatement, structural demolition of several buildings, and extensive tree removal services, addressing the complex challenges posed by each unique site. The project faced various challenges, including working in proximity to active railway lines, navigating TRCA regulated areas, and managing public safety through effective pedestrian walkways and coverage. Prior to the start of any work, Tri-Phase coordinated all required tree permits, demolition permits and utility disconnects for all locations.
The scope of work for the tree removal portion included tree removal of over 2500 trees ranging in size and diameter at designated locations around the Don Valley region. Some examples of challenges that had to be overcome was removal of trees on hills, and in close proximity to major infrastructure and structures.
