We designed alternative foundation system for a building over the existing SMART tunnel in KVMRT Line 2 project. The original design was bored pile with pile cap.
The site is underlying by limestone rock which was disturbed during construction of SMART tunnel. An cost-effective design using strip footing was proposed as an alternative to minimise the construction risk of bored piling work which is very near to the existing tunnel. The footing is generally placed on top of limestone rock. Pre-stressed transfer beams will then be constructed to transfer all the loads from the building above SMART tunnel onto the strip footings.
The construction is currently on-going at site.
