Bachy Soletanche has announced that it has secured a major contract to undertake piling work for Scotland’s largest waste water storage tunnel in Scotland.
The Shieldhall Tunnel project in Glasgow is part of a £100M investment being made by Scottish Water to improve water quality in the River Clyde and its tributaries and reduce flooding risk.
The overall project is being undertaken by a main contracting joint venture of Vinci Construction Grands Projets and Costain and Bachy will work as a subcontractor to the joint venture partners.
Bachy’s work on the scheme includes the construction of cased secant pile (CSP) for the first shaft of the tunnel, the service chamber and tunnel boring machine launch chamber, along with 400 linear metres of continuous flight auger contiguous piled walls for the cut and cover section of the tunnel.
The project is Bachy’s first using the CSP technique in Scotland. “This unique project will provide us with an excellent opportunity to deliver a real impact to the area’s infrastructure,” said Bachy Soletanche contracts manager for Scotland Paul Doyle.
“The project will be technically challenging, especially as we will be working within a residential area and in a restricted workspace, however we are confident our wealth of project experience will ensure we deliver exceptional standards throughout the work whilst minimising the impact on the local community.”
Bachy will start work on site in June and the piling is expected to take three months to complete but work on the tunnel between Queen’s Park and Craigton Industrial Estate is not scheduled to be completed until late 2017.
