The contract to extend the metro Green Line has yet to be awarded, according to sources familiar with the scheme.

The consortiums that submitted a bid for the contract in December last year are understood to include:

• Aktor (Greece) / Larsen & Toubro (India) / STFA (Turkey) / Yapi Merkezi (Turkey) / Aljaber Engineering (local)
• FCC (Spain) / Consolidated Contractors Company (Lebanon)
• Salini Impregilo (Italy) / SK Engineering & Construction (South Korea) / Galfar al-Misnad Engineering & Contracting (local)
• Porr (Austria) / Sixco / HBK Contracting (local)
• QDVC (France/local) / GS Engineering & Construction (South Korea) / Al-Darwish Engineering (local)
• Rizzani de Eccher (Italy) / Lotte E&C (South Korea) / Redco International (local)

Most of the prequalified groups are undertaking construction work on the first phase of the metro; the Porr-led team is currently executing the underground and elevated sections of the first phase of the Green Line.

The new Qatar Railways Company (Qatar Rail) project is known as Green Line extension phase 1a. The scope is understood to involve about 10 kilometres of tunnel and 10km of above ground track.

The client is also evaluating bids for a contract to build a metro station in Al-Khor as part of the Doha Metro Red Line North extension.

The Al-Khor metro station will link with the Al-Bayt stadium, which is being built for the 2022 Fifa World Cup.

The groups that submitted a bid for the contract in July include:

• FCC (Spain) / Consolidated Contractors Company (Lebanon)
• Porr (Austria) / HBK Contracting (local) / Midmac (local)
• Rizzani de Eccher (Italy) / Redco International (local)
• Salini Impregilo (Italy) / SK Engineering & Construction (South Korea)
• Yapi Merkezi (Turkey) / STFA (Turkey) / Al-Jaber Engineering (local)

The metro link is an essential component of the interconnected public transport required for holding the 2022 Fifa World Cup in Doha.

In July, it was announced that Turkey’s Tekfen Construction won the contract to build track works for the metro extension. The works will extend from the under-construction Red Line North to the planned metro station in Al-Khor.

The track follows the same alignment as the $2.1bn Al-Khor Expressway, which Tekfen won in 2016. The expressway is expected to be completed in 2019.
