Qatar Rail announced tunnelling work on the nothern section of Doha Metro's Red Line is now complete. 

The northern section has been built by the Impregilo-SK E&C-Galfar Al Misnad JV (ISG) consortium.

Tunnel boring machines (TBM) ‘Al Khor’, accomplished the final breakthrough between Legtaifiya Station and Qatar University (QU), the area where the Red Line emerges from the tunnels and rises onto a raised section running to Lusail.

At a media briefing to mark the milestone, Qatar Rail revealed that overall progress was moving ahead well, with over 85% of tunneling for the Doha Metro project completed and overall project completion reaching 37%.

There are currently 37 stations under construction with 17 at the stage where the concrete roof slab is being cast.

Doha Metro Red Line’s tunneling phase started on 19 July 2014 and runs for 41km from Al Wakra in the south through to Lusail.

Of the total 18 stations on the line, ISG is responsible for the construction of seven underground stations.

Four TBMs, digging an average of 30 meters per day at their peak, have worked on the line with the best daily rate of 42.0m achieved by TBM ‘Lebretha’ on 29 March 2015.

The completion of tunnelling works means over 70% of construction work for this section of the line is now complete.

Eng. Abdulla Al Subaie, managing director of Qatar Rail, said: “We are particularly delighted by the progress on this section of the project as we and our colleagues in ISG have had to overcome some significant challenges.

“It is well know that one of our TBMs was flooded one year ago and the achievement today shows how effective our recovery operations were and that overall project progress was not affected.”

He added: “Across the project as a whole we are continuing to move to plan. Later this year we will be over halfway to delivering the whole project and tunneling, which is currently at 85%, is expected to finish in the Autumn.

“At that point, we move from construction into systems installation as track, power supply and signaling starts to be installed. We also start the architectural finishes of the stations.”

Also commenting on the breakthrough, Dr. Eng. Saad Al Muhannadi, Qatar Rail chief executive officer, said: “Today is the first in a series of major milestones on the Doha Metro project over the next few months.

“Soon we will see the completion of tunneling on the Gold and Green Lines and, later in the year, our longest line – the Red Line, will also finish its tunnels."

Dr. Eng. Saad Al Muhannadi, said: “Soon, a mockup of the trains which will run on the Metro will arrive in Doha and we are planning to put this on public display to help us educate the public about our exciting new services.”

Barry Crouchman, project director for the ISG joint venture, added: “The combined efforts of the entire team, client, contractor and project manager, have resulted in the achievement which we celebrate today and is a shining example of what can be done when all parties unite in order to achieve a common goal.”

The network will consist of three railway lines: Doha Metro, a rapid transit system connecting communities within Doha and its suburbs, Lusail Light Rail Transit (LLRT), a tram service for convenient travel within the new city of Lusail and the long distance passenger and freight network, intended to link Qatar to the region and all are expected to be complete by 2030.

The first phase of the Doha Metro project is expected to be complete in the fourth quarter of 2019, while completion of the Lusail Tram is set for 2020.

With the completion of the first phase of the Doha Metro and Lusail Tram, Qatar Rail expects to offer 600,000 passenger trips per day by 2021.

By then, 37 metro stations are expected to be complete, with an average journey time of three minutes between adjacent stations.
