Vinci JV wins design-build contract for the southern red line of the Doha metro

14 June 2013

Qatar Rail has awarded the southern works package of the Doha metro red line to the consortium QDVC, owned 51% by Qatari Diar and 49% by Vinci Construction Grands Projets.

The consortium also includes Qatar’s Al-Darwish Engineering company and Korea’s GS Engineering and Contracting company.

The contract, with a value of about €1.5bn, covers design and construction of a dual-tube underground line with a length of 13.8km between the Doha airport and the Msheireb neighbourhood in the centre of the Qatari capital.

The contract also includes the design and construction of six underground stations, 51 safety connections between the tubes and three emergency evacuation shafts.

The works will take five years to complete and involve up to 3,000 people.

The future red line will run along the Gulf coast. Vinci says one of the project’s challenges will be to prevent water ingress during tunnel boring operations.

Five earth pressure tunnel boring machines with an outside diameter of more than 7m will operate simultaneously.

QDVC will try to minimise disruption to Doha’s heavy traffic by using an 8km system of conveyor belts for removing debris.

The red line will be the first of the four planned Doha metro lines.

Qatar Rail has awarded the Red Line North project to a consortium led by Impregilo, comprising SK Engineering & Construction and Galfar Al Misnad Engineering & Contracting.

The contract for the Green Line project has been awarded to a consortium led by PORR Bau GmbH and includes the Saudi Binladin Group and Hamad Bin Khalid Contracting.

A fourth contract has been awarded for the Major Stations project. There will be two stations included in this package, one at Msheireb and the other at the Education City. This contract has been awarded to a consortium led by Samsung C&T and comprises Obrascon Huarte Lain (OHL) and Qatar Building Company.
