The project includes the first phase of Bandırma-Bursa-Ayazma-Osmaneli Speed Railway Project which is the 55 km section of Bursa- Yenişehir line and Yenişehir-Osmaneli line. The line is being constructed for 250 km/h but the passenger train will be running at 200 km/h and freight trains will be running at 100 km/h.

Throughout the project 7 viaducts with total length of 4776 m, 7 bridges with total length of 600 m, 11 overpass bridges and 30 underpasses have been designed. Along the railway line stability and settlement problems have been encountered at various locations due to Bursa Plain consisting of alluvium which causes soft and weak soil conditions.

Therefore to overcome the stability and settlement problems on foundation of structures and fill basement alternative ground improvement projects have been designed. Dip mix, jet injection, concrete bored piles are some of the methods for improvement of the filling area basement.
