The Marmaray Project comprises of a major upgrading of the commuter rail system in Istanbul to connect Asia and Europe with an uninterrupted, modern, high capacity commuter rail system. Railway tracks on both sides of the Bosphorus (the Straits between the Black Sea and the Sea of Marmaray) will be linked to each other through a railway tunnel connection under the Bosphorus.
The BC1 contract is currently one of the most important civil engineering projects in the world. The scope of work involves the engineering, design, procurement and construction of approximately 13.6-km of railway and related structures. The main structures and systems include a 1.4-km long earthquake-proof immersed tunnel for the Bosphorus Crossing, bored tunnels and cut-and-cover tunnels under the city, at-grade and retained structures, four underground stations, one aboveground station, two ventilation buildings, bridges and viaducts, roads and intersections, trackworks, flood gates, electrical and mechanical systems, and other ancillary works.
The deepest point of the immersed tunnel is approximately 55 metres below sea level. Three of the four underground stations are on the European side, with the remaining station and a major road and bridge intersection on the Asian side. One of the stations is about 50 metres below ground level and will be constructed using the New Austrian Tunnelling Method. Once completed, the Bosphorus Crossing will be the backbone of Istanbul’s transport system and will help alleviate its urban transportation problems.
