SBB<\/a> has commissioned a consortium consisting of the construction companies Implenia<\/a> from Opfikon and Marti<\/a> from Zurich to build a new double-track line. As part of the Zurich-Winterthur multi-track<\/a> project, the Swiss Confederation and SBB are planning to build a new line and expand the stations in Dietlikon, Bassersdorf, Wallisellen and Winterthur T\u00f6ss. According to a statement<\/a>, Implenia and Marti will each take on 50 per cent of the construction of five of the six lots in the project. The total contract is worth around CHF 1.7 billion, with Implenia’s share amounting to around CHF 830 million. The project is expected to take around ten years to complete.<\/p>\n

As part of the project, Implenia and Marti will take on the construction of the Br\u00fcttener Tunnel (lot 240), the Winterthur section (lots 140 and 141), the Dietlikon section (lot 340) and the Wallisellen section (lot 540). The new double-track line through the Br\u00fcttener Tunnel is intended to eliminate the 8.3-kilometre capacity bottleneck in the rail network between Zurich and Winterthur. Part of the bottleneck is a branch line towards Zurich Airport. The underground double-track expansion will involve the construction of a single-track tunnel with a diameter of around ten metres for each direction of travel.<\/p>\n

According to the announcement, the infrastructure project is geared towards the mobility needs of future generations and is therefore in line with Implenia’s strategy. “We are delighted that Implenia, together with our consortium partner Marti, will be able to contribute our many years of experience and comprehensive expertise in infrastructure construction to make this important section fit for increasing frequencies and future requirements,” said Implenia CEO Jens Vollmar in the press release.<\/p>\n","protected":false},"excerpt":{"rendered":"
