ABSTRACT
The construction of the North-South Corridor (NSC) in Singapore, particularly at the interface with the Bukit Timah Canal (BTC) – a 35m wide and 5.5m deep canal, presents significant challenges due to site and environmental constraints. This paper will discuss the considerations taken during the design development of construction schemes, where the constraints, major challenges and construction risks were deliberated. In the final scheme adopted, the canal would not be diverted, and the Earth Retaining Stabilising Structure (ERSS) will be constructed through the “live” canal. This paper will also touch on measures taken to preserve the canal structural integrity and the work methodologies that were developed to address the risks associated with working within the canal.
