The elevated viaduct sections of the Doha Metro have been completed.

To mark the occasion of Qatar Rail completing the viaducts on the elevated sections of the Doha Metro Project, on Sunday 4 December, 2016, His Excellence Jassim Saif Ahmed Al Sulaiti, Minister of Transport and Communications and vice chairman of Rail Steering Committee, Eng. Abdulla Abdulaziz Al Subaie, managing director and chairman of the Executive Committee of Qatar Rail, Dr. Eng. Saad Ahmed Al Muhannadi, chief executive officer of Qatar Rail, as well as project directors and employees gathered at the ending point of the northern section of the Red Line Elevated and at Grade, where this milestone was achieved.

On the occasion, HE said: “Transportation projects have made significant strides and achievements under the wise leadership of HH the Emir Sheikh Tamim bin Hamad Al-Thani and follow-up and supervision of HE the Prime Minister and Interior Minister Sheikh Abdullah bin Nasser bin Khalifa Al-Thani.”

He pointed out that the achievement comes three months ahead of schedule and added: “I would also like to emphasise that the Ministry’s development plans for transportation projects in general are progressing significantly.”

Since work started on the metro’s viaducts in August 2015, a total of 8.7km of viaducts have been completed, comprising 2,293 segments.

A total of five launching girders were used to lift the segments, massive state-of-the-art pieces of equipment.

The launching girders usually span around 80m in length with a total weight of approximately 381 tons of steel.

Speaking on the occasion, Qatar Rail’s managing director and chairman of the Executive Committee, Eng. Abdulla Abdulaziz Al Subaie said, “I am delighted to be present to witness this significant milestone as the final segment was lifted in to place, completing all viaducts across the Doha Metro Project.”

He added that the viaduct completion is key, as its lines link to important landmarks such as Al Rayyan Stadium, Lusail Stadium, and Al Wakra City, as well as Qatar University and Lusail City in the west.

In addition, it delivers what will be vital links between Doha, The Mall of Qatar, and Al-Riffa area.

Al Subaie continued: “I would like to congratulate everyone involved in achieving this milestone for their hard work and dedication to a job well done. It is worth mentioning that the overall completion of Doha Metro now currently stands at 51%.”

Dr. Eng. Saad Ahmed Al Muhannadi, CEO of Qatar Rail also commented, “This is an incredible feat of engineering with extremely strict control required to construct such viaducts.

“We have used precast segments across the project, and compared to the traditional on-location casted structures there are numerous benefits including faster construction time, improved health and safety conditions, and a superior concrete quality of the precast.”

He went on to congratulate the team work and expertise displayed.

This part of the project follows shortly on from the completion of all tunneling across the Doha Metro Project, with the final breakthrough taking place on the 25th September 2016 at the Doha Metro project site of Terminal One of Hamad International Airport (HIA).

The final 111th kilometre was crossed by tunnel boring machine (TBM) ‘Msheireb’ on the southern part of Red Line of this landmark mega project.

The first phase of the Doha Metro is expected to be complete in 2020, when the project’s 37 metro stations are expected to be operative, with an average journey time of two minutes between adjacent stations.
