RECOVERY WORK
The first of three phases of recovery work involved implementing measures to mitigate “slope failure” and flood risk. This was completed that same month.
The second phase, completed in November 2022, involved stabilising the slope with steel sheet piping.
HDB said in an update in December 2022 that the final phase had begun, involving fully restoring the canal, reinstating the damaged part of the park connector, as well as reconstructing the slope and precinct structures within the development.
The Ulu Pandan (North Bank) park connector reopened in March 2023 after HDB removed the displaced soil in the affected segment of Sungei Ulu Pandan canal and restored the canal to its original depth and capacity.
Since then, HDB said it worked on “systematically strengthening different segments of the slope” as well as redesigning and reconstructing the slope within the Clementi NorthArc development.
It also reinstated the damaged stretch of the Ulu Pandan (South Bank) park connector between Commonwealth Avenue West and Clementi Avenue 6.
These included measures to further stabilise and strengthen the slope and refine the design of precinct facilities for added safety.
The slope was strengthened with more soil-retaining structures and anchors such as long piles and rebars. More jet grout piles were also injected underground.
In addition to expanding slope strengthening measures to extend to a wider stretch, HDB also said that it took the opportunity to review the design of the precinct facilities planned in the area for an “added buffer of safety”.
For example, some ramps and staircases were repositioned to more evenly distribute the load on the slope.
Following this, the remaining precinct facilities in the area were constructed. This included the multi-purpose court, hardcourt, precinct pavilion, drop-off porch, viewing deck and a covered linkway which connects the residential blocks to the precinct pavilion.
