Saudi Arabia’s Arriyadh Development Authority (ADA) has extended the closing date for the five main construction contracts to the estimated $7bn-8bn Riyadh metro project to 5 January.

The tenders were issued to contractors in August with a closing date of 1 December. It is understood that the extension was granted after contractors requested more time to prepare their bids.

The four prequalified consortiums are:

  • Vinci Construction Grand Projects (France)/Siemens (Germany)/Al-Mabani General Contractors (local)/Consolidated Contractors Company (CCC)(Athens-based)/Aecom (US)
  • Al-Rahji consortium – Al-Rahji Holding (local)/ Al-Arrab Contracting Company (local)/Obrascon Huarte Lain (OHL) (Spain)/Yapi Merkezi Insaat (Turkey)/GS Engineering & Construction (South Korea)/Bombardier (Canada)/Shibh al-Jazira Contracting Company (local)/Mott Macdonald (UK)/Parsons Brinckerhoff (US)
  • FCC Construccion (Spain)/Alstom Transport (France)/Samsung C&T Corporation(South Korea)/Alpine (Germany)/Strukton Civiel Projecten (Netherlands)/ Setec (France)/Tecnica Y Proyectos (Spain)
  • Ansaldo (Spain)/Stadler (Switzerland)/Strabag (Austria)/Larsen & Toubro (India)/Six Construct (Belgium)/ Mohammed Ali Al-Swailem Company (Masco) (local)/ IDOM (Spain)

The client has divided the six-line metro project into five major design and build packages, with lines 1 and 2 as one package, and with the other lines all as single packages. Each package will include the supply of rolling stock.

The six lines will have a total length of 180 kilometres.

The four consortiums have been prequalified for the whole metro project, but the construction packages will be split into different packages. The client is expected to shortlist prequalified firms to bid for the package to design and build lines 1 and 2 and/or 3, and will invite the prequalified firms to tender lines 4,5 and 6 at a later date.

The first line will run in a North-South direction alongside and under Olaya and Bat’ha streets. The line will start from the north at Prince Salman bin Abdulaziz Street and end at Hayer Road in the south. The line will run for 44km and contain 39 stations.

The second proposed line will run along King Abdullah Road, from King Saud University and the Eastern Sub Centre. It will be approximately 22.5km in length and will have 13 stations.

The third line will run alongside and under parts of the Al-Madinah and Al-Munawwararh roads. The line will be about 45km long and will contain 32 stations.

Line 4 will run north to south alongside Prince Saud bin-Muhammad bin Muqrin street, from the King Abdullah Financial District and King Khaled International airport. The line will be about 32km long and include 13 stations.

The fifth line will run in the North-South direction alongside and under King Abdulaziz street. The line will run between King Abdullah Financial District and Bat’ha street. The line will be about 26km long and have 25 stations.

Line 6 will run in an East-West direction along Abdulrahman bin Aouf Street and Sheikh Hassan bin Hussein bin Ali street. It will extend between Prince Saad bin Abdulrahman street and King Abdullah road. The line will have an approximate length of 12 km and have nine stations.

Beirut-based Dar al-Handasah and France’s Egis Rail have worked on preliminary designs for the metro project.

The metro project is part of Riyadh’s Public Transport Project (PTP) plan that was approved by the Council of Ministers on 23 April. The plan has been prepared by the High Authority for the development of the city of Riyadh.
