To improve the transportation system in Tamsui District, New Taipei, Taiwan. In April 2010 the government of Taiwan programmed the public viaduct-construction project, named Danjiang Bridge. The length of the bridge is 12.08km, the main bridge part is 920m, connecting Interchange in both sides with the width of the road of the bridge is between 44 to 71m and the height of the tower is 200m. The designer of main bridge part is Zaha Hadid, a brilliant well-known Iraqi-British architect. The bridge is expected to be the longest single-tower, cable-stayed bridge in the world. However, since the bridge tower is designed in three dimension gradually varied section, so it is considered quite a challenge to complete the BIM and constructing which make it one of the most difficult projects that no one has ever done.
We are university students from Civil Engineering of Tamkang University and our adviser is Dr. Yi-Feng Chao. We challenged the difficulty of this program, by building up the BIM of the main bridge part of Dainjiang Bridge. During modeling process, we face any BIM of Danjiang Bridge problem head-on and try to solve it quickly and painlessly via Tekla Structures. Besides, we used many tools to complete the three dimension gradually varied main bridge part of Danjiang Bridge, including Autocad, Grasshopper, and Rhino. In detailed, we used “rebar set” and “rebar group” of Tekla Structures to complete all of the Danjiang bridge rebar arrangement, meanwhile evading all the possibility of interfering collision. At the same time, in order to make the model look more realistic. We used the 3D technique of Lumion to simulate the bridge in real site and used virtual reality to materialize it physically. So here Danjiang Bridge is, as we present.
