Hochtief, Murphy chosen to build tunnel for the £2.4bn York potash mine

WCN Editorial Team 6 Jun 2016 EUROPE BUILDINGS

A joint venture between Murphy and Hochtief has been chosen as preferred contractor by Sirius Minerals to build the tunnel for the £2.4bn potash mine in North Yorkshire.

The 37km underground tunnel, to be designed and built by the JV, will transport minerals from the mine to a processing plant on Teesside.

This will involve a 6m-diameter TBM-bored tunnel between the mine head site at Dove’s Nest Farm near Whitby, and a portal near the town of Redcar.

Designed by Arup, the plan is to use five hard rock TBMs, which will be lowered in at four intermediate staging shafts, at a starting depth of 350m below the surface at the mine head.

The 12-month first phase of work will comprise front-end engineering design and a detailed geotech programme along the route.

Chris Fraser, Sirius Minerals managing director and CEO, said: “This is the culmination of a huge amount of work by both the successful bidders and those that have been unsuccessful and we thank all of the groups involved for their efforts.

“We are delighted to now be moving forward with our selected partners towards the implementation of the project.”

AMC UK​, ​a joint venture between Thyssen Group and Redpath Group​, ​​has been ​also selected as preferred contractor for mine site development​.
