MRT Wanda Line Phase II Puts BIM Integration Technology to Good Use to Overcome Difficulties in the Construction

MRT Wanda line Phase II section contract CQ890 construction is entering an important foundational construction phase. Owing to intricate underground pipelines and important livelihood pipelines in the construction area, a number of difficulties and risks will be faced during construction. After implementing this section construction contract, the construction company will carry out tasks for the entire line which include a pipeline trial excavation and drainage box culvert longitudinal survey to ensure the differences between pipeline maps and actual locations. The construction team must not only integrate the paths of all types of pipelines but also avoid pier foundations in the limited underground spaces and search for the optimal paths for major pipeline migrations in order to eliminate construction obstacles brought about by the locations of bridge foundations and to carry out the construction of the viaduct foundations.

DORTS Second District Project Office (2nd DPO) stated that to overcome these difficulties and ensure a detailed understanding of the paths of each important pipeline in order to be able to flexibly adjust the basic foundations and avoid the risk of damages caused by construction, the construction team on this contract are making special use of Building Information Modeling (BIM) technology. This technology creates comprehensive 3D information about underground pipelines in accordance with categories, and in addition to accurately representing the position of the pipelines, it can also assist in simulating and planning construction processes in the vicinity of major pipelines. DORTS 2nd DPO further emphasized that although BIM technology is already extensively employed in a variety of construction projects, this is the first time that DORTS has attempted to use it to model the construction of underground pipelines which are 6.6 kilometers in length. Building models takes time and effort, especially with the complex underground pipeline data of the Taipei Metropolitan Area. Nevertheless, making the most of the opportunity of this MRT construction project and reestablishing the details of the pipelines underneath the roads will be of great assistance for lifecycle operations and maintenance of underground pipelines along MRT lines in the future. DORTS stated that in addition to continuing to assist the New Taipei City Government in promoting urban renovation and MRT projects, DORTS’ construction experience and advanced technology will be utilized to create forward-looking planning and make contributions for the sustainable development of urban areas along MRT lines.

On September 15 in the morning, Taipei City DORTS Commissioner Cheng De-fa and New Taipei City DORTS Commissioner Li Zheng-an led the construction team together in hosting a simple and solemn groundbreaking ceremony for the foundation piles. The construction of the bridge pier foundation pile project commenced on that day, and in addition to showcasing the preliminary results of the section contract CQ890 construction team’s utilization of engineering technology to overcome underground pipeline obstacles, it also symbolizes that Wanda line Phase II construction has already entered the important phase of constructing main structures. 2nd DPO will continue to lead the MRT construction team and continue to strive to gradually overcome construction difficulties and obstacles in order to realize the objective of opening Wanda line Phase II for operations as soon as possible.
