This Hanoi road-renewal case records traffic continuity, utility coordination, ground preparation and pavement inspection while the road remains in use.
Construction stages
Work is divided by area and time. Before each section opens, check barriers, signs, lighting and pedestrian routes. Plans identify utility interfaces and pavement reinstatement deadlines.
Quality checks
- Verify underground services before excavation and update site markings when discrepancies are found.
- Record testing and acceptance of subgrade and base layers by operation; resolve outstanding issues before proceeding.
- Check joints, surface evenness, drainage falls and details around manhole covers.
Review findings
Urban road works require daily coordination of materials and workmanship with traffic, temporary drainage and community communication. Measures follow site findings and the responsible authority's requirements.
