It was announced that the tunnel excavation and covering works for Marmaray, which is an undersea rail tunnel being constructed to link the European and Asian sections of Istanbul, running under the Bosphorus strait would be completed 2011.

Mr. Mustafa Demir, the Mayor of the Fatih Municipality and Mr. Sıraç Karayağız, the Deputy Director of Railways, Ports, and Airports Construction (DLH) inspected the Marmaray construction area and gave information about the already completed work to members of the press. Mr. Karayağız noted that the tunnel excavation and covering works for Marmaray linking the European and Asian sections of Istanbul together by an undersea rail tunnel would be completed 2011. He also said that the excavation work was being carried according to a new method called “the Austria method” at the Sirkeci Station and that the excavation works were being conducted by hand, not by the TBN machines because the station area coveres a large area.

Mr. Karayağız stated that the North and South tunnels at the Sirkeci Station would be used for both directions. He also indicated that the length of the tunnel extending between Yenikapı and Sirkeci which was originally 2,141 meters long, has been extended to 3,076 meters with the Sirkeci Station. “TBM machines have started to be used for the tunnel excavation works and approximately 15 meters excavation work is being completed per day. During the excavation works at the construction site, we do not face any problems such as influx of water or joint opening, but the buildings which have been adversely affected by the operation of the machines located on route must be removed immediately,” he said.

“During the project, totally thirty-three buildings have been strengthened; twenty-seven of which were strengthened by the Deputy Director of Railways, Ports, and Airports Construction (DLH). Nine buildings at risk of collapse must be evacuated immediately,” Mr. Karayağız said. He continued saying that they personally spoke to people living in these buildings and if these buildings have been damaged during the construction work, they would be restored to an equal or better condition. Mr. Karayağız continued saying that the DLH would also voice support of the projects and that the Yenikapı archaelogical excavations which is being continued on a more comprehensive scale has not prevented the continuation of works in the area. He also specified that the tunnel excavation works were on course and would be completed within the shortest time.
