Monday, June 27th, 2022

Dr. Sauer & Partners was proud to sponsor, and also host a booth at the NAT 2022 last week in Philadelphia. It was a great opportunity to meet friends and colleagues from the North American tunnelling industry!

In addition, Senior Tunnel Engineer, Mr Elmar Feigl presented his paper 'Underpinning of an Operational Subway Aided by Mined Galleries' which discussed the use of SEM drifts to facilitate a large underpinning scheme of the operational Line 1 Finch branch of the Toronto subway system.
