Technical Director, Thomas Schwind Presents at BTYSM Evening Lectures

Monday, April 1st, 2019

On Thursday 4th April, Dr. Sauer & Partners’ Technical Director, Thomas Schwind will take to the stage for the BTSYM Evening Lectures series. He will present our work on the Confederation Line in Ottawa. 

The confederation line in Ottawa comprises 15 stations and stops; its centrepiece is a 2.5km long tunnel with three underground stations below downtown Ottawa. The mined construction method for the stations was chosen in order to minimise the impact to the surface. The underground stations are located directly adjacent to existing, sensitive and sometimes historic buildings requiring detailed studies of risks during construction and risk mitigation measures. 

Through his presentation, Thomas will look at the detail behind the design and subsequent construction of three large caverns at shallow depth and twin track running tunnels in rock.
