The project A new facility for a oating dock with 12.5m CD water depth required dredging of 90,000m 3 material and construction of a 185m quay wall. The challenge The works had to be carried out in a shortened contract period in a very conned construction site. Dredging had to be coordinated with quay wall and peripheral works to prevent interference. The solution Dormac-Dock QuayFranki’s innovative combination of CFA piles and jet grout columns meant early completion of the quay wall structure. Additional works incorporated the closing of an unused slipway and earthworks, paving and treatment works.
