Huge infrastructure project now half complete after final breakthrough at Hamad International Airport
One of Qatar’s most important megaprojects has reached a significant milestone as the remaining tunnelling work for the Doha Metro was completed on Monday.
Qatar Rail said that all 111 kilometres of tunnels for the metro network had now been dug, with the final breakthrough taking place at Hamad International Airport.
The company said that the work had required nearly half a million concrete segments to create just over 70,000 tunnel rings.
The work has been carried out by 21 tunnel boring machines manufactured by German firm Herrenknecht.
The Doha Metro megaproject as a whole is now half complete, with Qatar Rail now focusing on laying tracks, fitting out the stations and awaiting the arrival of the train mockups.
“Completion of tunneling on the Doha Metro is yet another major milestone for the project and one we are delighted to have achieved on plan and to schedule,” said Qatar Rail chief executive officer Saad Al Muhannadi in a press statement.
“Until now 7.5km of above ground tracks viaducts have been installed and base slab and foundations have been completed on 33 stations. Roofs have been completed on 8 stations and roof slabs are progressing at 27 different stations.
The first phase of the metro will open in 2020, while all three segments of Qatar’s rail network – the metro, the Lusail Tram and the inter-GCC rail connection – are expected to be up and running by 2030.
