Soft soils
Due to the challenging nature of the soft ground in the Taipei basin, geotechnical engineering plays a crucial role in the safe design and construction of the Taipei MRT network. To reduce the risk caused by geotechnical problems during the construction and operation phases of Taipei MRT, the Department of Rapid Transit Systems (DORTS) of the Taipei Municipal Government commissioned MAA as Geotechnical Engineering Specialty Consultant (GESC) to advise and assist DORTS on geotechnical matters.

Geotechnical risk management adopted for everyTaipei MRT Lines
The scope of provided services includes the review of detail design, tender documents, geotechnical design summary and special provisions rendered by the Detailed Design Consultants (DDC) in the design stage. In the construction stage, GESC is responsible for the review of geotechnical design and construction documents, establishment of an Integrated Data Storage Center and collection, maintenance, and analysis of monitoring data. In addition, geotechnical technology transfer through GESC’s daily operation and a series of technical lectures as well as technical courses were given by GESC to DORTS. In its capacity of GESC, MAA helps DORTS manage the risk caused by geotechnical uncertainties, advises DORTS on possible claims due to changed ground conditions, and improves the quality of design and construction of the Taipei Rapid Transit System (TRTS). Today, MAA GESC’s expertise has been formally adopted on all Taipei MRT Lines, including new lines such as the Circular Line, the Tucheng Line (Dingpu Section), the Xinyi Line East Extended Section and the Taoyuan Airport MRT Line.
