Project Update News

A multi-purpose steel trestle designed by Intesca-Inarsa & Dr. Sauer & Partners facilitated the successful lifting of the 43.5ft diameter and 3,000-ton heavy TBM, ‘CHESSIE’ from a barge onto the Southern Island.

We are happy to share that Dr. Sauer & Partners has been selected by Transport for London (TfL) with support from Arup to undertake a Bakerloo Line Extension feasibility study.

With the recent pre-opening of SFMTA’s Central Subway line between Chinatown and 4th and Brannan, Dr. Sauer & Partners looks back with a sense of achievement on its role in the project. 

We are delighted that for some of the team working on Euston Station, their hard work has paid off and they have been presented with awards.

A recent article in TunnelTalk shares the detail for the complex and innovative solution that the Dr. Sauer & Partners team in Canada provided for the award-winning Highway 401 and 409 Twin SEM Tunnels in Toronto.

We are delighted that the Tunnelling Association of Canada has selected the GO Expansion: Highway 401 and 409 Twin SEM Tunnels Project as the as the 2022 recipient of its Canadian Project of the Year (Over $100M CAD) Award.

With future extensions of the Eglinton Crosstown LRT line due to commence in the near future, this short video by World Infra gives a good overview of the future plans for the entire line.

The Highway 401 and 409 Rail Tunnel is a Metrolinx project delivered in partnership with Infrastructure Ontario.  The two new 180 m tunnels constructed under 21 lanes of one of the busiest highways in North America will provide a capacity increase on the Kitchener GO line helping to bring more frequent, all-day, two-way service on core segments of the network and even allowing for double-stacked freight. 

Dr. Sauer & Partners has been providing detailed design of excavation and support for the primary lining of the tunnelsthat are currently being constructed under Jerusalem. At the time of reporting more than 65% of tunnels have already been excavated.

Tunnelling works were successfully completed at Bank Station Capacity Upgrade (BSCU) on the 10th of February.
