Abstract: |
Doha, the capital of Qatar, is being developed into a modern centre for trade and industry. One essential part of the implementation of this aim is the provision of modern mass-transport. The "Qatar Integrated Railway Project" includes both high-speed railway lines and a metro system in Doha. Die Doha Metro has three lines. The network will have a total line length of 216 km in the first extension stage, of which 96 km run underground. The Green Line was awarded to a Joint Venture of Porr (lead), Saudi Bin Laden Group and the local construction company HBK. The contract includes turnkey completion of the underground section of the Green Line with a tunnel length of 2 × 17 km, six stations, gauge changing equipment and switches as well as cross-passages and emergency exit shafts. The project is being implemented as design and build. The paper reports on experience with assembly work under the difficult conditions of the Middle East as well as the first few weeks of tunnelling. |
