A significant integration will be achieved with the connection of the terminal station of Aksaray Airport Light Rail line which is located in Aksaray to Yenikapı Station. The route between Aksaray Station and Yenikapı Subway Station was designed as 417 meters of bored tunnel and 208 meters of cut-and-cover tunnel. 524 meters of tunnel were excavated and concreted so far.
Currently, archaeological research excavation prior to cut-and-cover structuring within the last section of 70 meters in the connection point to Yenikapı Station is still in progress.
Following the completion of the excavations carried out under the supervision of Directorate of Istanbul Archaeology Museums, the construction activities for the integration of Light Rail System to Yenikapı Station will be commenced with the aim of completion in the soonest time possible.

The excavation activities of the Otogar-Bağcılar (Kirazlı) Light Rail System line in Bağcılar Station were completed by the end of 2012.
The construction works in Menderes, Üçyüzlü, Kirazlı Stations were completed while the testing and commission activities in scope of electromechanical works are still in progress.
Currently Otogar-Airport line intersects with Esenler-Otogar line and administration losses are encountered due to the trains waiting for each other. With the completion of Esenler Viaduct, the negativity emerging from the overlapping Otogar-Airport line and Esenler-Otogar line will be resolved and continuous administration will be ensured for both lines. The construction works are still in progress in Esenler viaducts for this purpose while the installation of steel girders were commenced following the completion of all columns and end carriages constructions.
With the completion of Light Rail System line at the second half of 2013, the entire line is planned to be commissioned (Otogar-Bağcılar-Başakşehir-Olimpiyat Village Subway Line).

Kadıköy-Kartal Subway Ayrılıkçeşme Station Supplementary Construction
The integration of Kadıköy Kartal Line to Marmaray was planned to be located in Ayrılıkçeşme Station. Due to the Marmaray construction activities lagging behind Kadıköy Kartal subway activities and the high demand of passengers, Kadıköy Kartal line was commissioned. However the concourse structure for admitting passengers in Ayrılıkçeşme Station could not be constructed.
With the commissioning of Marmaray in scope of this work, the integration will be achieved. Therefore, the subway networks of Istanbul on Asian and European sides will be connected.
In scope of this work;
- The craftsmanship works of stair tunnels,
- Construction and craftsmanship works of the tunnel which connects two structures at the station and located in the architectural project,
- Production of the rough construction and craftsmanship
