Key Challenges
Very tight schedule for foundation works:
- Limited space available
- Bore piling are constructed simultaneouslywith the secant pile wall & diaphragm wall
Central location in down-town District 1
- Concrete supply & soil removal at night time
- High speed of delivery, to complete the pileWith INSEE Network of plants (from 3 locations)
- Closed roads around holidays/festivities
Very close to InterContinental Hotel & Residences:
- Focus drilling works during daytime
- Reduce noise during concrete deliveries
