Marine Site Investigation Works for 'Long Island' [Concluded]

As part of the ongoing technical studies for 'Long Island' reclamation works, HDB conducted site investigation works in the waters off East Coast Park from August 2025 to April 2026. During these site investigation works, marine barges used onboard rigs to conduct borehole drilling, soil sampling and in-situ field tests. Survey boats also conducted side scan sonar, geophysical and cable detection surveys. These initial studies gathered essential information, such as an understanding of the geological and seabed conditions, which will guide the future 'Long Island' reclamation project's design and planning. The marine site investigation works, which have since concluded, did not result in any pollution or environmental impact.
