Qatar Railways Company (Qatar Rail) has awarded the team of Austria’s Porr, Saudi Binladin Group and the local HBK Contracting Company a third major construction contract on the Doha Metro scheme.

The new contract covers the elevated sections of the Green Line. The joint venture is already working on the underground sections of the Green Line. It was awarded that estimated QR8bn ($2.2bn) contract in May 2013. It was awarded the contract early to complete the enabling works for the first phase of the metro.

Qatar Rail is still evaluating bids for the contract to build the elevated sections of the Red Line North. In March 2014  a $700m contract to build a section of the Doha Metro’s Red Line was awarded to a consortium of Spain’s FCC, Geneva-registered Archirodon Construction, Turkey’s Yuksel, and the local Petroserv.

All the underground sections of the first phase of the metro have been awarded. The final contract was awarded in late April when Qatar Rail formally signed the estimated QR12bn deal to build the underground sections of the Doha Metro’s Gold Line to a consortium of Greece’s Aktor, Turkey’s Yapi Merkezi and STFA, India’s Larsen & Toubro and the local Aljaber Engineering.

The work includes building three stations at Barwa Village, Al-Wakrah and Qatar Economic Zone, and a 7-kilometre-long section of elevated metro line. The contract duration is 31 months.

In 2013, the estimated QR8bn Red Line South underground sections construction package was awarded to a consortium of the local/French QDVC, South Korea’s GS Engineering & Construction and the local Darwish Engineering.

The estimated QR8bn contract for the Red Line North underground sections was secured by a consortium of Italy’s Impregilo, South Korea’s SK Engineering & Construction and the local Galfar al-Misnad Engineering & Contracting.

South Korea’s Samsung C&T, Spain’s OHL and Qatar Building Company won the estimated QR4bn deal to build two major stations at Msheireb and Education City.

For the contract to supply and install the systems, rolling stock and track work for the first phase of the metro network, Qatar Rail received revised prices from bidders that include a lump sum price for the depot. Earlier bids included a provisional sum for these works.

The groups competing for the deal are Germany’s Siemens; a team of Italy’s Ansaldo STS and Spain’s CAF; a group of three Japanese companies – Mitsubishi, Hitachi and Kinkyshario, and France’s Thales. The initial prices were submitted in March.

The six-year contract covers the design, integration, manufacturing, supply, delivery, testing and commissioning of the trains and other required equipment.
