Metro rail system
Riyadh metro is a rapid transit system under construction in Riyadh, Saudi Arabia. It is part of the Riyadh Public Transport Project (RPTP), which will be the largest public transport project. The RPTP comprises the construction of a metro network, a bus system and other transport services in Riyadh.
Construction of the Riyadh metro project began in April 2014, while tunnelling work on Line 1 started in July 2015. Test runs on the metro commenced in August 2018 and it is due to open in 2020.
Arriyadh Development Authority (ADA) is the owner and operator of Riyadh metro. The project will have an execution period of five years and an optional maintenance service period for the next ten years. It is expected to create more than 15,000 jobs in Saudi Arabia.
Riyadh had a population of 5.7 million in 2012, which is predicted to increase to eight million by 2030. The new metro system is expected to fulfil the demands of the growing population, as well as reduce traffic congestion and improve air quality.
The RPTP’s plan was developed by the High Commission for the Development of Arriyadh. The plan received approval from the Riyadh Council of Ministers in April 2012.
The RPTP project will also include construction of a bus network. The 85km three-line Bus Rapid Transport (BRT) network will connect major locations in Riyadh. All metro stations will be integrated with the bus network.
Riyadh metro project will be 176km-long with six lines and 85 stations, including underground, elevated and at-grade sections. Line 1, the Blue Line will run from Olaya Street to Al Hayer Road. It will be 38km-long and will include 22 stations and four transfer stations connecting to other metro lines.
The Red Line, or Line 2, will connect King Abdullah Road to the King Fahad Stadium. It will be 25.3km long and have 13 stations along with three transfer stations.
The longest line of the metro will be the 40.7km-long Line 3, or Orange Line, which will run from Madina Al Munawra to Rahman Al Awal Road.
Line 4, the 29km Yellow Line, will run from the King Khaled International Airport to the new King Abdullah Financial District (KAFD), and include eight stations. Line 5, the Green Line, will be 13km long and start from the King Abdul Aziz Road. It will include 11 stations and two transfer stations.
Line 6, the Purple Line, will start at King Abdullah Financial District and end at Prince Saad Ibn Abdulrahman Al Awal Road. Featuring six stations, it will be 21km long and mostly above ground.
ADA selected three architecture firms to design and build three major stations of the system, namely the Olaya Metro Station, the Downtown Metro Station and the King Abdullah Financial District Metro Station.
Gerber Architekten designed the Olaya Metro Station. The station will be located at the intersection of Lines 1 and 2 and will feature a public plaza, a large entrance hall, and an open concourse. The station will have a gross floor area of 68.85m² and a gross volume of 387m³. ADA is expected to invest $20m in the station.
Snohetta designed the Downtown station (Qasr Al Hokm). The station is being constructed between the Al Madinah Al Munnawarah Street and King Faisal Street. The station will act as a transport hub for Lines 1 and 3.
Zaha Hadid was selected to design and build King Abdullah Financial District (KAFD) Metro Station. The station is located at the east of the Northern Ring Road and slightly west of the King Fahad Road. It will serve Lines 1, 4 and 6.
Renewable energy will be used to provide power for all the metro stations.
ADA awarded the design and construction contract of the Riyadh metro to three consortiums BACS, Arriyadh New Mobility (ANM) and FAST, in August 2013.
The BACS consortium includes Bechtel, Almabani General Contractors, Consolidated Contractors Company, Siemens and AECOM. The consortium is led by Bechtel and is responsible for designing and constructing Lines 1 and 2 under a $9.4bn contract. It is also responsible for the train cars, signalling, electrification and integration of the lines to the metro network.
ANM’s $5.2bn contract includes construction of Line 3 of the metro, Qasr Al Hokom station and Western Station. The ANM consortium includes Ansaldo STS, Salini-Impregilo, Larsen & Toubro, Nesma, Bombardier, Hyder Consulting, IDOM and Worley Parsons Arabia. Larsen & Toubro and Nesma are providing civil works services, Bombardier is responsible for the procurement of the vehicles.
Ansaldo STS will provide technology support services for Line 3. It will also provide signalling support services, automation train control (ATC) and communication-based train control (CBTC), as well as other telecommunication services. The contract value for Ansaldo STS is $680m with an option to add $249m for maintenance of Line 3 for the next ten years.
Led by FCC Construction, FAST received a $7.9bn contract to construct and design lines 4, 5 and 6 of the metro. The consortium includes FCC Construction, Samsung C&T Corporation, Alstom Transport, Strukton Civiel, Freyssinet Saudi Arabia, Atkins, Tecnica Y Proyectos and Setec. The contract includes construction of 64.6km of rail track, 29.8km of viaducts, 26.6km of underground track and 8.2km of overground track.
Underground tunnels are being built with the help of three tunnel boring machines (TBM). The tunnels have a 10m-diameter to facilitate the three metro lines. The $7.9bn contract is financed through the Public Investment Fund of the Government of Saudi Arabia.
Alstom is providing its automated driverless metro system for the metro project under a $1.5bn (€1.2bn) contract. Herrenknecht supplied six tunnel boring machines for the construction of Line 1 and Line 5.
In August 2013, a joint venture of WSP (formerly Louis Berger) and Hill International was awarded a $265m contract to offer project and construction management services for Lines 4, 5 and 6 and associated stations and tunnels. A joint venture of Egis, Parsons and Systra received a €425m ($563m) project management contract for Lines 1, 2 and 3.
L&T Construction won a $161.37m contract to design and construct ballastless tracks for Lines 1 and 2. Indra received a €266m ($320m) ticketing and access control technology contract for the Riyadh metro project in January 2015.
Ansaldo STS was awarded a $2.9bn contract by ADA in September 2018 to provide its operation and maintenance services for a period of 12 years for Lines 3, 4, 5 and 6.
The FCC Industrial Division was awarded a $332m contract to provide electromechanical installation of services for the Green and Purple Lines of the Riyadh metro project in July 2016. The contract included lighting, ventilation, fire-fighting and air conditioning systems on the two metro lines.
A joint venture of Capital Metro Company (CAMCO), RATP Dev (a subsidiary of RATP Group) and Saudi Public Transport Company (SAPTCO) was awarded a 12-year contract by ADA to provide operations and maintenance (O&M) services for Lines 1 and 2 in September 2018. The contract includes the delivery of security, passenger assistance, and facility management services.
Terrasol, Techture, Eversendai Engineering Saudi, Trimble Solutions Corporation, Perkins&Will, Ayesa, Dogus Insaat Ve Ticaret, Salcef Group, Rhomberg Sersa Rail Group, ByrneLooby, 3TI Progetti, BDP, Pedelta, Prointec, Systech International, AVK Holding, Dextra Group, Otis Saudi Arabia and CCL are some of the suppliers and contractors involved in the project.
Alstom provided 69 metro trains for the Riyadh metro project, with the last trainset shipped in February 2019. It also agreed to supply its Urbalis signalling system, a train braking, energy-recovery system called HESOP, and Appitrack, a new technology to install tracks faster.
The metro trains will be operated in automated mode. Each train will have two cars. The driverless metro train will be 36m-long and 2.71m-wide.
Bombardier Transportation built 47 INNOVIA Metro 300 trains sets in Mexico, and the trains are shipped by DHL to Riyadh. The driverless trains aim to provide a comfortable and convenient riding experience for passengers.
Siemens agreed to provide 67 Inspiro type metro vehicles for Lines 1 and 2 with two to four cars each, suitable for operation in adverse climatic conditions.
In June 2018, Alstom began conducting initial dynamic tests for the Riyadh metro project. The test involves performance testing of the railway system using the previously delivered trains.
