Tunneling

High Performance Fire Protection Ideal for Use in Tunnels

Newly developed MH Box Machine

The demand for new underground infrastructures for pedestrians and cyclists is increasing along with the rapidly growing traffic load in large and megacities. This makes it necessary to cross beneath a great number of busy junctions, expressways or railway routes at short distances and at a low depth. The high traffic burden at these intersections makes aboveground interventions extremely difficult or even impossible without a great deal of additional work and expense.

Toronto tunnel project helps meet increased demand for power

The need to replace aging underground infrastructure has led Hydro One Networks Inc. and Toronto Hydro to join forces to upgrade the existing 115 kV transmission lines in the midtown power corridor in Toronto. The project involves installing an additional 115 kV circuit between the Leaside Transformer Station and the Birch Ave. junction.
