Bestmind assisted SWS Engineering S.p.A. in the design management of a portfolio of 8 different railway projects for the same end customer, TCDD (Türkiye Cumhuriyeti Devlet Demiryolları - Turkish State Railways).
The portfolio included lines totalling about 800 km in length, of which about 500 km are high speed.
1 - Adapazarı - Istanbul High Speed
2 - Sivas - Erzincan High Speed
All projects included: cartography, corridor study, alignment definition, geological and geotechnical investigations, environmental impact assessment (EIA), hydraulic studies, road diversions, station design, tunnel design, viaduct design with different technologies, cost estimates, technical specifications and contractual documents.
