Atakoy İkitelli Metro Line is one of the most important metro lines of Istanbul, which connects Bakırkoy – Bahcelievler – Bagcilar – Kucukcekmece – Basaksehir districts and is planned to provide public transportation service to the entire Basin Express road. Atakoy Ikitelli line has stations integrated with Marmaray, Metrobus, Beylikduzu – Sefakoy, Bahcelievler – Bagcilar, Halkali – Kirazli and Mahmutbey – Esenyurt metro lines.


It is a rail system project with approximately 13.5 km long main line tunnels, a total of 11 tunnel and cut-and-cover type stations, approximately one km overnight tunnel and an energy supply center.


Prota has undertaken the preparation of concept, preliminary, final and detail projects of this line. It is planned that the line will carry 412,000 passengers daily in 2024. The distance between Atakoy and Ikitelli will decrease to 21,5 minutes.


The project is carried out using Building Information Modeling (BIM) system. The design made with the BIM system by Prota BIM Team ranked in the infra-structure category, among the top three in the Autodesk AEC Excellence 2018 awards, where 256 projects competed from 32 different countries.
