Whether above the ground, on the ground or below the ground, rapid transit systems have been in existence for more than a hundred years now and have proven to be one of the most effective and convenient ways of transporting the masses from one destination to another in a crowded urban environment. The stations and trains of these systems have without a doubt been through some changes over the years, but the concept of providing a safe, fast and systematic form of transport to the public without any traffic worries has always remained the same. Thus, with most of Taipei's residents in the past having to face the burden of either being packed like sardines on the bus or battling others behind the wheel at a snail's pace, the stage was set for bringing some much needed relief to Taipei's commuters with Taiwan's first rapid transit system, the Taipei Rapid Transit System (TRTS).

Planning for the TRTS began in 1975 long before the Department of Rapid Transit Systems (DORTS) was formed in 1987 under the Taipei City Government to implement the TRTS project. CECI took part in a number of international consortiums with consulting firms from North America and Europe with the main objective of establishing the initial network of a world class mass rapid transit (MRT) system that provides safety, convenience, comfort and beauty. Such a task would naturally require a tremendous amount of effort and patience from all of those involved, including the related government authorities, international and local consultants, construction contractors as well as the public, but once all of the planning studies had been completed and the initial route network was formally approved for design and construction, a new era of technology and urban living was ready to roll in Taiwan.


Besides providing an alternative mode of transportation, the TRTS project brought about a number of new learning experiences for both those building the system and those using the system. Taiwan's engineering consultants now had the opportunity to acquire the technological know-how of constructing the nation's first MRT system while adopting a number of different construction techniques, including the cut-and-cover method, the shield tunneling method, and the launching truss method to minimize the impact on the environment and traffic. There was no shortage of engineering challenges for the first stage of the TRTS network as the line sections would wind their way through a limited amount of space over cramped streets, underneath rivers and building structures, or nearby historic relics, landmarks, hospitals, schools, etc., all of which are located in an active seismic area. Therefore, strict design criteria and rigid monitoring systems were carefully applied through all stages of work so as to ensure the system's safety during construction and operation.

But in addition to the technical construction and operation, the TRTS has a human side to show the public the other roles in life an MRT system can play. More than transportation, the TRTS space provides a new look to Taipei's urban environment and a new lifestyle to Taipei's residents by offering a positive and upbeat atmosphere with facilities such as underground streets and shopping malls, showcases of public art, a gathering place for cultural activities, attractive landscapes, linear parks and open plazas as well as displays of unique themes of architecture. In fact, you could say that the clean, orderly and courteous environment of the TRTS creates a new type of culture for Taipei from which people of all walks of life can share something in common with each other and take pride in their city.


Further to CECI's role in establishing the initial TRTS network during the study and planning of the system nearly 40 years ago, CECI began providing both General Consulting and Detailed Design Consulting Services in 1988 to carry out detailed design lots for both elevated and underground works on the TRTS Project. These services so far include:

  1. 26 underground stations.
  2. Over 41.22km of bored tunnel.
  3. Over 5km of cut and cover tunnel.
  4. 444m of NATM tunnel (single track).
  5. 10 elevated stations.
  6. 11.447km of viaduct structure.
  7. Three underground pedestrian and shopping malls.
  8. Basic design and detailed design of the Xinzhuang and Luzhou Depots.

And in keeping with DORTS developmental strategy of optimizing the MRT network so that it will be fully integrated with other modes of transportation and serve the entire metropolitan area, CECI has also been carrying out planning studies for other potential at-grade, underground or elevated rapid transit lines on the system's long-term network, which will henceforth allow DORTS achieve its ultimate goal of providing a world class MRT system to the residents of Taipei, and carry over its success to other MRT projects throughout Taiwan.
