İstanbul Metro Taksim – 4th Levent Electromechanical System Additional Works

After we completed the excavation, reinforced concrete tunnel liner and the grouting of the preliminary maintenance area, we placed the precision controlled under-rail concrete. Steel boxed profiles are placed with chemical grouted anchor bolts on the leveled concrete with precision control. This way the rails were raised for the maintenance of the cars. In addition, we built the locker rooms, toilets, etc. for this area.
