To host international events, the city of Auckland launched the Downtown Infrastructure Development Programme (DIDP). The aim was to make the waterfront
more earthquake-resistant, pleasant and functional.
The works include the seismic reinforcement of the road and networks behind the existing quay wall, the modification of the existing pier with the creation of 6 berths for ferries and the creation of a public space along the quay, as well as the redevelopment of Quay Street. The special works mainly concern reinforcement behind the existing quay wall.
As part of the “Early Contractor Involvement”, Soletanche Bachy International developed an alternative solution combining bored piles, anchors and jet grouting, in order to optimize planning and adapt to the dense urban environment and different geological conditions of the waterfront.
