Thailand: Bangkok MRT Orange Line East section

"Following (Arup's) successful work on the Bangkok MRT Blue Line Phase 1 North Section and its extension, Arup was appointed by Italian-Thai Development Ltd as their preferred partner to work on the detailed design of the section between Hua Mak and Khong Ban Ma stations.

The project involves the design and construction of approximately 4km long twin bored tunnels with three underground stations, three ventilation shafts and a cut-and-cover tunnel."
