|Mass Rapid Transit Systems|
Bangkok 's notoriously congested traffic has provided ITD with construction challenges rarely found around the world when constructing the elevated and underground mass transit systems.
Commencing commercial service in late 1999 over some of the busiest main thoroughfares in Bangkok, ITD constructed the 23 km Bangkok Mass Transit System built on a 12 m high elevated concrete superstructure founded on piles extending up to 50 m below grade to provide a dual track heavy passenger train network. With two routes and 25 stations, the system has a peak capacity of 50,000 passengers per hour. The elevated viaduct segments were precast at ITD's Wihan Daeng ISO 9002 certified concrete precast facility at a rate of 10,000 m3 per month, transported to site and lifted onto the cast in-situ concrete superstructure support columns. The train systems for this turnkey project were provided by Siemens and the whole project was managed by the Siemens ITD Consortium.
