The role of geotechnical engineering in the design and construction of the Taipei Rapid Transit Systems (TRTS) cannot be over-emphasized. To reduce the risk caused by geotechnical problems during construction and operation of TRTS, the Department of Rapid Transit Systems (DORTS) of the Taipei Municipal Government commissioned MAA as the Geotechnical Engineering Specialty Consultant (GESC) to advise and assist DORTS on matter of geotechnical concern. The scope of services included the review of detail design material, tender documents, and geotechnical design summary and special provisions rendered by Detail Design Consultants (DDC) in design stage. In the construction stage, GESC was responsible for the review of geotechnical design and construction documents, establishment of 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 the capacity of GESC, MAA helped DORTS manage the risk caused by geotechnical uncertainties, advised DORTS on possible claims due to changed ground conditions, and improved the quality of design and construction of TRTS. The contributions of GESC were generally recognized by the DORTS, DDCs, and contractors.
