Västlänken – The West Link Project, Korsvägen construction section in Gothenburg, Sweden

AbstractWest Link (Swedish: Västlänken) is one of the biggest infrastructure projects in Sweden building an in total 8 km double‐track railway tunnel in Gothenburg, which is currently under construction. “E05 Korsvägen” is a construction lot which is part of the West Link project with the Swedish transport authority Trafikverket as the client. The works were awarded to the Joint Venture (JV) West Link Contractors consisting of Wayss & Freytag Ingenieurbau AG and NCC. A special contract model with a design and build part combined with a regular bill of quantities comprises building an underground double‐track railway tunnel with a length of 3.2 km and the new Korsvägen station. This sub‐project includes three drill and blast sections and three open excavation sections. All three construction pits will be executed in challenging soft ground conditions. The JV is confronted with high environmental demands and special requirements for the blasting works in the urban area of Gothenburg.
