• OCT was responsible in the first phase for detailed design as follows;
• Superstructure and substructure of railway viaducts along the project route with the typical span length of 30 – 45 m.
• Balanced Cantilevered railway bridge over Diyawanna Lake with four spans of 100m. and two 60m. side span (total length is 520 m.). Superstructure is concrete box girder and substructure is 2m.-diameter bored pile foundation. 
• Three elevated stations, and elevated depot platform and depot buildings. The design included architectural, structural and building services works. We utilized 3D Building Information Modeling (BIM) for station design across multiple disciplines, including architecture, structure and building services, in order to avoid unexpected clashes.  All drawings production were made directly from BIM model.
