An MXKD 50 on a 15 m lattice tower and a BSA 2110 HP D stationary concrete pump started work in February 2010 on the Marmaray tunnel section, which is being built using an open construction method. The base area of the excavation is approximately 300 m long and 35 m wide, and was divided into a total of 29 concreting sections for the concreting of the foundations. Each section – approx. 10 x 35 m and 2 m thick – is concreted using a monolithic method. About 120 m3 of concrete are installed in each layer with a thickness of approx. 40 cm. Hence an average of 650 m3 of concrete are installed for each of the 29 foundation sections.
