Evaluation points

  • A submerged tunnel was constructed at a water depth of 60m. which is the world deepest construction point. The water level difference between the Black Sea and the Sea of Marmara, wind direction, and other factors result in drastically transforming ocean currents. And, due to the drastically transforming currents, directions of upper- and lower- currents become different. Although the submerged tunnel construction of sunken tunnel elements under such conditions was extremely challenging, this project was achieved with the use of high-level techniques of Japanese companies.
  • The attempt to directly connect a shield tunnel with sunken tunnel elements was the world's first. However, a new construction method, which maintains robust cut off performance under high water pressure, was developed to achieve highly safe and precise construction of the junction.
  • In Istanbul, a city with a history of at least 2000 years, there is an antiquity layer under the ground and clusters of historical buildings on the ground. In such city, subway-station construction had to be proceeded while paying sensitive cares in excavation and protection of the buried cultural properties. Under such difficult conditions, the construction was completed within the contract construction period and the Bosporus-traversing part was opened.
  • In the project, a large number of locals were employed: in the submerged tunnel construction, up to 600 locals, in the drilling works for the station areas, up to 1000 locals were employed. In addition, this project regularly employed approximately 30 local engineers to transfer technologies associated with the submerged tunneling method, which had been incorporated for the first time in Turkey, and other methods.
