As work continues at the Woodsmith Mine, sinking of two 1600m deep service and production shafts is underway and the 25m x 15m elliptical shaft brow within the MTS Shaft Inset has recently completed. Horizontal development of the MTS Station Chamber is also underway.
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.
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.
