COURTESY UNIVERSITY OF TORONTO — An aerial view of the front campus under construction at the University of Toronto, St. George looking south. Over 370 boreholes have been drilled 250 metres deep under front campus, nearly half the height of the CN Tower.

Crews are preparing the footings, shoring walls and utilities for a one-level underground parking garage amidst the historic buildings at the downtown St. George campus of the University of Toronto (U of T).

Below the parking garage, crews have bored a field of 370 wells and inserted a series of U-shaped pipes that will be filled with a mixture of glycol and water and linked to a network of heat pumps that will serve the heating and cooling systems in U of T’s existing buildings. Some of the pipes go down 250 metres.
