The Gold Line Metro of Doha, a project constructed by AKTOR as leader of the ALYSJ international Joint Venture, opened its gates to the public a few days ago in Qatar.
It is the largest Metro project ever undertaken and implemented by a Greek construction company abroad and one of the largest projects a Greek company has ever realized at an international level, with its total budget exceeding $3 billion. At the same time, the Gold Line Metro of Doha constitutes an extremely demanding and complex world-class construction and the largest single construction package of Doha’s new Metro network.
Besides the subsidiary of ELLAKTOR Group, the ALYSJ Joint Venture consisted of the Indian Larsen & Toubro Limited, the Turkish Yapi Merkezi Insaat Ve Sanayi A.S and Sezai Turkes Feyzi Akkaya Marine Construction STFA, as well as the Qatari Al Jaber Engineering LLC.
Indicative of the international character, the size and complexity of the Gold Line Metro is that the project included the construction of 23.3km of underground tunnels and 10 underground stations of high-level architecture, aesthetics and luxury, with state-of-the-art automations and electromechanical systems.
Tunneling for Doha’s Gold Line Metro required the simultaneous utilization of 6 different Tunnel Boring Machines (TBMs), while at the peak of its construction, 13,580 employees from 58 different countries were simultaneously employed.
The project’s underground passage in the heart of the city, combined with the peculiar geological environment of the area presented major construction challenges, among which, the need for a large number of traffic detours and shifts of utility networks, as well the pumping of a total 129 million m³ of groundwater for the construction of the stations, due to the presence of large groundwater inflows in the area.
In total, the project involved the excavation of 4.9 million m³ at the stations, incorporation of over 1 million m³ of concrete and the use of approximately 171,400 tons of steel reinforcement.
The Gold Line Metro is designed and constructed to reflect Qatar’s cultural heritage, tradition and environment in a contemporary manner. The ceilings of the Gold Line stations are designed with vaulted spaces, drawing inspiration from Qatar’s old architecture and traditional Bedouin tents, while it is also noteworthy that the floor of the Gold Line contains aggregates of real gold and a metallic gold tile specially designed for Doha’s Metro adorn the stations’ walls.
It is noted that AKTOR Qatar WLL, AKTOR‘s arm in Qatar, is also leading the consortium that, in partnership with Qatari company Como Facilities Management Services, has undertaken through a 20-year contract with a total budget of €517 million, the maintenance of the entire 100 km long Doha Metro network, with 37 ground and underground stations, as well as the entire Tram network of the city, with 45 ground and underground stations and 3 depots. This is also the largest project ever undertaken by a Greek company in the field of Facility Management.
