|---|---|
| Client | Public Utilities Board (PUB) |
| Project status | Ongoing |
| Commencement date | 3rd March 2022 |
| Depth of shafts | up to 32m |
| Pipe size | 900 and 1600mm diameter |
| Jacking length | 674m |
| Category | Industrial Water (NEWater, potable water) |
| Description | This project entails twin pipe jacking works of 900mm diameter pipes of 85m x 2 across the Jurong Island Highway, as well as deep shaft excavation up to 32m in depth through reclaimed sandy conditions and hard ground condition, continuous pipe jacking spanning up to 540m through sandy conditions and hard ground condition. Since most of the work is being done on the road, we also need to consider the sensitive stakeholder work activities in the region, work in very tight spaces, and be extremely thorough with our cable detection work. To reduce ground movement, an appropriate ERSS must be implemented. |
