Technology Proposal for Curved Concrete Tracks Construction of 2018 Winter Olympic Sliding Center in Pyeongchang

For the curved concrete track construction of 2018 winter Olympic sliding center in Pyeongchang, in this study proposed the digital fabrication technology using CNC. This method can control the 3D geometries of the curved concrete structure based on the digital design. Conventional method generates the construction errors because this method fabricates many temporary zig bar using 1:1 full size drawing for install frozen pipes and sets up each zig bars at the construction site. Propose method is effective to ensure the precise fabrication and construction of zig bars. Also this method can eliminate errors of the frozen pipes position and curved concrete construction.
