Particulars of design
The metro rail project, which is predicted to cost $36 billion, will be developed in two phases and is expected to be one of the world's most contemporary railway networks.
Once fully operational, the metro system is scheduled to span 300 kilometers and include four lines dubbed Red, Green, Gold, and Blue.
The project's first phase included the construction of the Red, Green, and Gold lines, as well as 37 stations. Phase two will include the addition of the Blue line to the network as well as the extension of current lines. By 2026, the city's metro network is planned to grow by approximately 60 stations.
Metro lines and routes in Doha
The Red Line, often known as the Coast Line, connects Al Wakra to Lusail via the Hamad International Airport. The 40-kilometer-long line features 18 stations, including Legtaifiya, where passengers can transfer to Lusail Tram services.
The Green Line, often known as the Education Line, is 22 kilometers long and connects Al Riffa to Al Mansoura. The line is made up of 11 stops, including Msheireb, Hamad Hospital, the Qatar National Library, and Education City.
Ras Bu Aboud and Al Aziziya are connected by the Historic Line, or Gold Line. Eleven stops are located along the 14-kilometer course.
The Blue Route, or City Line, will be a 17.5-kilometer-long semi-circular line that will connect the West Bay and Airport City North districts via the main C-Ring Road.
In March 2014, a consortium comprised of Mitsubishi Heavy Industries (MHI), Mitsubishi Corporation, Hitachi, Kinki Sharyo, and Thales submitted a bid for the turnkey construction of a fully automated driverless metro system. In February 2015, the consortium was awarded a letter of conditional acceptance (LCA).
The scope of work comprised the provision of 75 sets of three-car trains, tracks, platform screen doors, a railway yard, a signaling system, power distribution, tunnel ventilation, and telecommunications. The Doha Metro's first four train sets were delivered in August 2017.
MHI is responsible for overall project management, system integration, and tunnel ventilation work as the consortium's head. Additionally, it supplied the power distribution system, screen doors and tracks for the platform.
Mitsubishi Corporation supplied the rail cars in conjunction with Kinki Sharyo. Thales will supply advanced communications-based train control (CBTC) signaling, telecommunications and security, an integrated operational control center, and fare collection systems.
Hitachi was responsible for a portion of the project's management and maintenance, which included the delivery of specialized maintenance vehicles for inspecting railway tracks and electric train lines.
Kinki Sharyo secured an order in October 2018 to deliver an additional 35 trains, bringing the fleet's total to 110. The new fleet is being built to accommodate the additional passenger traffic expected during the FIFA World Cup in 2022.
Details on Doha's metro rail infrastructure
The metro's four lines will connect the city's major hubs, including Education City and West Bay, the Lusail urban development area, Doha Airport, the business and conference center, and the stadiums for the 2022 FIFA World Cup.
The majority of the metro system's infrastructure is underground and was built via tunnels. The underground parts were dug using tunnel boring machines (TBMs). Additionally, the Red and Green lines have elevated and at-grade sections.
Contractors entrusted with the job
In 2013, Jacobs Engineering was given a project management and consulting engineering contract for the Red line, while a comparable contract for the Gold Line and key stations was awarded to a team comprised of Louis Berger and Egis Rail. Hill International was tasked with the responsibility of managing the Green Line. These three contracts are projected to be worth $313.16 million in total.
Lloyd's Register was given a QR55 million ($15.1 million) safety assessment contract the same year.
The Red Line North design contract was awarded in April 2013 to a consortium led by Italian construction giant Impregilo and including South Korea's S K Engineering & Construction and Qatar's Galfar Engineering & Contracting. The partnership was tasked with designing and constructing 13 kilometers of twin-bore underground tunnels and seven underground stations, commencing with Msheireb.
Qatar Rail won the $1.82 billion design-build contract for the Red Line South in June 2013 to a consortium led by QDVC, a joint venture between Qatari Diar and France's Vinci Construction Grands Projects. Additionally, the consortium, which includes GS Engineering and Construction of South Korea and Al-Darwish Engineering of Qatar, has been contracted to design and construct a 12.8-kilometer dual-tube subterranean line connecting Msheireb Station to the New Doha International Airport.
In June 2013, a consortium led by Austrian contractor Porr, Saudi Binladin, and HBK Contracting Company was given a $2.5 billion contract to design and construct the Green Line between Msheireb and Al Rayyan Stadium.
In the same month, a consortium comprised of Samsung C&T, Obrascon Huarte Lain (OHL), and Qatar Building Company (QBC) was awarded a $1.4 billion contract to construct the project's two major stations at Msheireb and Education City.
In March 2014, the FCC-led consortium inked a $700 million deal with Archirodon (Greece), Yüksel (Turkey), and Petroserv (Qatar) to build a 6.97-kilometer segment of the Red Line along with three elevated stations. In April 2014, a consortium led by Greek firm Ellaktor was given a $3.3 billion contract for the design and construction of the Gold Line. The consortium also included Turkish firms Yapi Merkezi and STFA, India's Larsen & Toubro, and Qatar's Al Jaber Engineering.
In the same month, the SYSTRA-Parsons joint venture was granted a €170 million contract for phase one project management and work supervision.
Atkins was named lead designer for the Gold Line and Red South Subway lines.
UNStudio was selected by Qatar Rail as the primary architect for the Qatar Integrated Railway Project. In September 2014, it completed phase one of the project, which included the design of more than 30 stations.
