Red Line Tel Aviv: Planning and Construction of the TBM Tunnels of the Eastern Section (Part 1)

The Red Line is the first line of the Tel Aviv urban railway. 2 x 2.7 km tunnels were driven using two EPB tunnel boring machines (EPBs) from Herrenknecht for the eastern section of the Red Line. It is being built by a joint venture comprising the Israeli construction company Danya Cebus and the Chinese contractor CCECC. The WBI GmbH carried out the detailed design and accompanied construction activities on behalf of the consortium. This report provides an overview of the project and the ground conditions. Furthermore, the planning, lab tests and findings from executing the TBM drives from the Depot portal to Ben Gurion Station are described.
