The Taiwan High Speed Rail (THSR) Project, with a US $ 14.9 billion capital investment, is the biggest BOT project in the world at the time of inception. The THSR will shorten travel time between Taipei and Kaohsiung of Taiwan to a short 90 minutes. Similar to Shinkansen of Japan, the THSR is designed at a 350km/hr speed, with adequate safety system and minimal pollution. Once completed, it will become a highly competitive transportation mode alternative for travelers. The 345 km long system is built through 12 turnkey packages awarded to joint ventures comprised of international and local contractors. There are 10 stations, 1 workshop station, 2 maintenance bases and 3 depots. Since 1990s, MAA has been heavily involved in THSR including providing design services for eight packages with 195km line structure, and independent checking service for two packages with 80km line structure, one depot and one station. All these services involve construction of 174km viaduct, 13km tunnel and 8km at-grade section.
