Abstract

Hatch started with two main focuses: metals and subways. Engineers at Hatch designed the University subway, the first of its kind in Toronto and have designed subways and transit systems in Toronto, Vancouver, Buffalo, Los Angeles, Washington, Sydney and others. Working with CN and CP, Hatch designed and construction managed the replacements for the rail tunnels under the St. Clair river between Canada and the US. Each of these projects also required noise and vibration services to design quiet tunnel ventilation systems, to control ground borne vibration, station acoustics and to assess noise on the surface.
