Qatar Rail has announced the completion of tunneling on the northern section of the Doha Metro’s Red Line. One of the company’s record breaking tunnel boring machines achieved the final breakthrough on this part of the line between Legtaifiya Station and Qatar University (QU). This is the spot where the Red Line emerges from the tunnels and rises up onto an elevated section running past QU and on to Lusail.
Tunneling on the Doha Metro Red Line started in July 2014 and runs for 41 km from Al Wakra in the south through to Lusail. The northern section from Msheireb to Lusail is constructed by international consortium Impregilo-SK E&C-Galfar Al Misnad JV (ISG) In addition to the tunnels ISG is responsible for the construction of seven underground stations. These are out of a total 18 stations on the line as a whole. Among the stations on the northern section is Al Qassar, where a mock of a station interior was built to showcase the materials being used in the station interior fittings.
A total of four TBMs have worked on the line digging an average of 30 meters per day at their peak on this section. The end of tunneling means that over 70% the total construction on this section of the Line is now complete.
Qatar Rail also reported that overall progress was moving ahead well, with over 85% of tunneling for the Doha Metro project finished and overall project completion reaching 37%. 37 stations are also under construction with 17 at the stage where the concrete roof slab is being cast.
