Dubai’s Roads and Transport Authority (RTA) has announced that 50% of the main tunneling works of the Dubai Metro’s Route 2020 project – at depths of 12 to 36 metres and extending 3.2km – has been completed.
According to Mattar Al Tayer, Director General and Chairman of the Board of Executive Directors of Roads and Transport Authority (RTA), as of date, the completion rate of stations’ construction on the route ranges from 4 to 42%.
Route 2020 spans 15km, from Nakheel Harbour and Tower station on the Dubai Metro’s Red Line, up to the Expo 2020 site.
Inspecting the tunneling work which began last October, Al Tayer was briefed that the giant tunnel boring machine, known as ‘Al Wugeisha Expo 2020’, commenced tunnel drilling works at Al Furjan, has passed Discovery Gardens and reached near Jumeirah Golf Estates this February. It will continue tunneling up to Dubai Investment Park. All tunnel-related works are scheduled for completion this December.
Al Wugeisha can crush stones and penetrate through sandy layers or any soil components encountered during the drilling process. It has a huge metal gear supported by an automated tail. At the front, it has a cutting wheel with a cavity, the shape of which varies according to the type of drilling and soil layers.
Currently, the architectural, constructional and electromechanical designs are being developed for Expo station, elevated and underground stations, and Nakheel Harbour and Tower station.
The work completion rate in the underground station at Jumeirah Golf Estates has reached 42%, whereas the completion rate of the underground station at Dubai Investment Park has reached 8%. The completion rate has reached 14% in the elevated station at Al Furjan, 12% in the elevated station at Discovery Gardens, 7% in Expo station, and 3% in Nakheel Harbour and Tower station. Completion rate has reached 50% in the deep foundations of Nakheel Harbour and Tower station.
According to Al Tayer, the work progress of the project is moving according to the approved time chart, while confirming that the first of the new metro carriages for the Route 2020 project are expected to arrive this July. Construction works involving the project’s viaducts are expected to be completed this November.
All rail works of Route 2020 are expected to be completed in July 2019, with test-runs of the metro carriages due to begin in February 2020.
