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
