Construction, testing, and commissioning of a new watermain in downtown Toronto. The project was executed through complex ground conditions using multiple tunnel boring methods and involved several shafts of varying sizes and depths. The installation of a large-diameter watermain required careful coordination to maintain traffic flow and emergency access to two major hospitals within the downtown core.

• Largest watermain project in the City of Toronto’s history
• Urban construction within a densely developed area
• Innovative shaft design solutions
• Mixed ground conditions management
