The main challenges of the first phase of the Doha Metro project were the region’s geology – with the city built largely on limestone – and the need to perform construction work in densely populated urban areas, such as the impressive Corniche promenade, the high-rise districts of Doha City and the tourist centers with their numerous hotel complexes. A special alignment technology was used during tunneling to prevent subsidence of the buildings above. The materials used also had to be designed for the special climatic conditions. They can withstand temperature fluctuations of up to 40°C. Optimal temperature conditions inside the tunnel were ensured by a powerful tunnel air conditioning and ventilation system.
Despite the many challenges, the project was completed to the full satisfaction of the client. DB Engineering & Consulting supported the project management as well as the coordination of an international team and ensured a high standard. This meant that all work could be provided to a high quality, within budget, and on time. With this project, the company has helped to create a modern and sustainable mass transit infrastructure in Qatar.
In Lusail, a new city north of Doha built since the year 2000, the metro network is supplemented by the Lusail Tram, another QIRP subproject. This has four lines with 25 above-ground and underground stops and is connected to the metro network via two interchange stations: Lusail and Legtaifiya on the Red Line. Here, DB Engineering & Consulting supported the client in the architectural design and planning of all stations, including intermodality and landscaping.
