Services Period

From December 2005

to 2023 (on-going)

Type of Services

Engineering Design and Construction Supervision

Project Overview


Taoyuan Metro is the operator of the Taiwan Taoyuan International Airport Rapid Transit Line which opened up for commercial service in March 2017.


This rapid transit line connects Taiwan Taoyuan International Airport with surrounding transportation hubs such as Taipei Main Station and the Taoyuan High Speed Rail Station.  


The 51.5 kilometer long route has 7 underground stations and 15 elevated stations and features two types of service: 


(1) an express service from Taipei Station to the Airport in approximately 35 minutes and


(2) a commuter type service which travels the whole length of the route in approximately 58 minutes. 


Approximately 80% of the route is elevated and travels through a variety of urban and rural areas​, while the underground portions of the route are located at:


  • the first station (A1 Station) just west of Taipei Main Station,

  • the National Taiwan Sports University Station in Guishan District of Taoyuan (A7),

  • underneath the Airport and adjacent to the Airport Hotel (A12, A13, A14, A14a),

  • the terminal Huanbei Station (A21) in Taoyuan.

More Projects

CECI has been providing consulting services for a number of the Taiwan Taoyuan International Airport Rapid Transit Line design lot projects, including:

Design Lot DA115 Project from Taipei Station (A1) to Sanchong Station (A2) -


The scope of work for this section has a total length of approximately 3.6 kilometers and includes the design of

  • Elevated structure (1,447m in length) at the Sanchong end of New Taipei City,

  • Daylighting structure (373m) at the Sanchong end of New Taipei City,

  • Bored tunnel (1585m long) that passes through the Tamsui River,

  • Cut & cover tunnel (213m) at Taipei City end and Station A1, and

  • Joint development common-structural buildings.


The Taipei Station (A1 Station) and joint development common-structural buildings are designed in coordination with the Japanese architect, Fumihiko Maki, where A1 station has four levels below ground and will be part of a future twin towers landmark development in Taipei. ​


Design Lot DE01 Project from Sanchong Station (A2) to National Taiwan Sports University Station (A7) -


The scope of work for this section has a total length of 13.3 kilometers and includes the design and construction supervision of ​


  • 5 elevated stations (A2, A3, A4, A5, A6),

  • 12.4 kilometers of elevated viaduct structure, and

  • 900 meter long tunnel when approaching the underground A7 Station.

Design Lot DU01 Project (Underground Sections) -

The Design Lot DU01 project is the design and construction supervision services for the underground portions of the rapid transit line and comprises two directional track over a combined route length of 8.41 kilometers including


  • Single track bored tunnels (twin tube) sections with tunnel section lengths of 769 meters + 111 meters + 647 meters + 844 meters + 1234 meters (combined total length of 7.21km for both tunnels),

  • 2.2 kilometer long cut and cover tunnels with either two or three portals,

  • 1.1 kilometer long unearthed section,

  • 4 day-lighting structure sections (318 meters, 305 meters, 170 meters and 425 meters),

  • 112 meter long tunnel integrated with the basement structure of Airport Terminal 2,

  • 6 underground stations (A7, A12, A13, A14, A14a, A21),

  • Drainage and sewerage systems for handling rainwater and sewage,

  • Protection or permanent diversion of utilities beneath the roads,

  • Retaining wall and slope protection near the entrances of A12 Station, and

  • Substations for power supply.


This Design Lot Project was Taiwan’s first case in which automatic monitoring systems were utilized during the construction of a rapid transit system and is Taiwan’s largest scale bored tunnel rail transport project situated in a mixed ground comprised of gravel deposit and muddy sandstone.
