This Can Tho drainage-renewal case covers wet-season pipe installation, traffic diversion, temporary drainage and coordination with neighbouring businesses.
Pre-construction surveys
Survey pipes, manholes, road levels and flood points together. Mark uncertain locations for investigation instead of relying solely on old drawings during excavation.
Implementation controls
- Provide temporary drainage routes and emergency pumping before closing the existing system.
- Excavate, install, inspect and backfill in short sections to limit open trenches.
- Update diversions as work moves, maintaining pedestrian and emergency access.
- Check pipe invert levels, joints and manholes before reinstating the road.
Continued monitoring
Rainfall observations and post-completion inspections help assess performance. Involve the maintenance team early and continue checking settlement, blockages and areas around manhole covers.
