Doha rolls out metro contracts
6 Jun 2013
Peter Kenyon, TunnelTalk
- The Impregilo (Italy)/SK Engineering (South Korea)/Galfar Engineering (Oman) joint venture is selected to excavate the first underground section of the US$36 billion Doha Metro in Qatar.
- TunnelTalk reported last month (April 2013) that the Impregilo-led consortium had been selected as "preferred bidder" by the Qatar Railways Company (QRail) for construction of the first 13km of the Red Line North between Msheireb and the new city of Lusail (Fig 1). On Friday (May 17) Impregilo, which holds the largest share of the consortium (41.25%), confirmed award of the design-build contract in an official statement.
- The contract, for a 13.1km length of line that runs north from Msheireb Station in downtown Doha, comprises seven underground stations and 11.6km of twin running tunnels with an i.d. of 6.17m.
- "Total contract amount of the Red Line North Underground is approximately 8.4 billion Qatari Riyals [US$2.3 billion] of which US$810 million is relative to the planning and civil works, and approximately US$1.49 billion of provisional sums for preparatory works, electro-mechanical plant and architectural works for the stations," said Impregilo in a statement.
- The award is the first major contract win since Impregilo was acquired by Italian construction firm Salini in April. A spokesman said: "The Middle East, and in particular the countries of the Persian Gulf region, represent a priority for the Salini-Impregilo Group's future. More specifically, the Group is already involved in Qatar in the design and construction of the first phase of the Abu Hamour (Musaimeer) water system in Doha, which will collect surface and underground rainwater and includes the construction of a 9.5km surface and ground water drainage tunnel."

Phase 1 underground alignments of Doha metro
- Qatari Rail confirms selection of the Porr (Austria)/ Saudi Binladen Group (Saudi Arabia)/HBK Contracting (Qatar) JV for construction of the underground alignment of the Doha Metro Green (Education City) Line.
-
The 65.3km line includes 37km of twin running TBM-bored tunnels, and most of the 31 stations will be underground. The design-build contract is the largest on the mega project. The Porr-led JV beat off rival bids from:
• Taisei/Redco
• Habtoor Leighton/John
Holland/ Dragados
• Larsen & Toubro/J&P/Shanghai Tunnel/Al-Sraiya
• FCC Construccion/ Alpine/ Archirodon Construction/Petroserv
• Züblin/ Strabag/ China Civil Engineering/ Redco/ Rizzani de Eccher
• Implenia/ Daewoo/Orascom/Contrack International - In a first phase of construction the line will connect the downtown station of Msheireb with the Qatar Convention Center, Doha West International station and the Al Rayyan sports stadium in the west of the Qatari capital.
- Also awarded is the design-build contract for the 12.8km of twin-running underground tunnels of the Red Line South between Msheirab and Doha International Airport. The winning JV is led by QDVC, a team consisting of Qatari Diar and Vinci Construction. This partnership already holds a number of key infrastructure contracts in the country. Other JV partners are GS Engineering and Al-Darwish Engineering.
- The Impregilo/SK Engineering/Galfar joint venture is also prequalified for the contract to excavate 13.1km of twin running tunnels for the east-west Gold Line.
- The Red Line North is eventually planned, during Phase 2, to extend a further 42.6km to Al Khor North on a mixture of elevated and at grade alignment. Other lines will also be extended above ground during Phase 2. Prequalification for the 17.5km all-underground semi-circular Blue Line that will link West Bay and the airport has not yet started.
