Singapore Waterfront
Challenge
SeaTec was tasked with civil engineering operations to regenerate the waterfront area, transforming wharves and piers into a new lifestyle area. Operations were in accordance with Singapore regulations, SeaTec safety management system and prime contractor’s onsite regulations. The key challenges focused on restricted crane access and the ability to undertake dry repairs on some areas.
Solution
- Inspection of the existing structures prior to commencement of civil engineering works to map and locale all subsea piles etc.
- Removal of all existing condemned piles by means of underwater oxy-arc cutting. Due to restricted crane access, piles were recovered to a suitable location using appropriate lift bags prior to craning from the water.
- In-water positioning of new structures for the pier area.
- Fabrication and placement of large cofferdams in existing sub-sea culverts in order to allow dry repairs to the pipeline systems.
- Carry out seabed inspection work to map profiles and remove debris which may have proven a hazard to future navigation adjacent to jetty areas.
