This was a very challenging project of installing a series of 1000 mm diameter steel tubular piles in very steep slope. The retaining wall was constructed to create a space for a new railway track. An extensive series of FEM analysis was conducted during the design stage to avoid excess movement of a large apartment building and houses that existed on the hill, which was cut to create the new space. An innovative design of a continuous beam attached to the sequence of tubular piles was adopted to improve the stiffness of the wall. The construction of the wall was executed successfully. The project deserves IPA award as it will be an excellent case study that demonstrates the use of innovative solution to create a new structure in densely populated urban area.
