In the year 2020 Dubai will host the World Expo, consequently there is a range of infrastructure upgrades and construction in preparation. The Route 2020 Metro Project is an extension of the existing Dubai Metro Red Line, consisting of a branch line starting at Nakheel Harbour and Tower Station and extending to the 2020 Expo Site. The 9.6m Diameter TBM was launched with only 2m of cover. The Lining design for the tunnel is SFRC Segments however the launch section was designed for standard RC segments. Tunnelling commenced in October 2017 and was completed in June 2018 ahead of schedule, marking a significant milestone on one of the region’s most economically significant projects. This presentation looks at the associated works including soil replacement, de-watering and the series of pile and slab structures that enabled the tunnel to be launched at such shallow depths, as well as the reasons why it was undertaken.
