The method also provides greater flexibility to create more geometries and distinctive architectural designs that would be difficult to achieve using conventional construction methods.
However, LTA noted that 3D concrete printing remains an “emerging technology” for infrastructure.
“This project is a pilot to assess its feasibility on specific applications in infrastructure implementation, and we will continue to explore its potential through further trials where appropriate, while keeping abreast of developments and opportunities.”
TESTING
Working with Witteveen+Bos, LTA designed the pedestrian bridge to comprise 10 concrete segments. The segments will be assembled and threaded with steel cables running through openings along the length of the bridge.
