T.Y. Lin International (TYLI Taiwan) provided civil engineering services for the Taipei Metro Tamsui Line in Taipei City, Taiwan.
The 23.2-kilometer-long Tamsui Line is a high-capacity underground, at grade, and elevated rapid transit line, with 21 stations and the Beitou Maintenance Depot. TYLI Taiwan was responsible for the YuanShan to Beitou elevated section of the line, including 10 stations
- The line was divided for up and down rails, each 4.5 meters wide and 1.3 meters deep box girders with spans ranging from 20-26 meters.
- Precast prestressed concrete box girders were used for shorter spans. Cast in-situ box girders were used for continuous longer spans when crossing physical obstacles (river and roadway), with the Keelung River Bridge as the longest, with spans of 45m-69m-69m-45m.
- The 10 stations all adopt traditional Chinese architecture. The design of the roof looks like the Chinese character "人", assembled from hollow square steel sections.
- Beitou Station is the only station on the Tamsui Line that adopts the space truss design and transparent curtain wall with a modern aesthetic.
- Chientan Station possesses many special features, including a “dragon boat”-shaped roof that is suspended by steel cables to two pylon columns at a height of 38 meters, over a length of 180 meters.
TYLI Taiwan provided civil engineering services for the 10 stations, utilities design, environmental control, elevator and escalator planning and design, and technical service.
