The piles, beams and platform slab were constructed from land using the ‘land infill’ method in order to save project delivery time. This allowed the quay to be constructed in some 20 months time from initial piling to vessel visit.
Both the land infill material and natural strata were a reasonably consistent medium sand. Piles were 1.2 m Ø reinforced concrete cast insitu. Excavation under the platform down to mid tide level was by excavators and the underwater slope was dredged with Toyo pumps handled by purpose made barges. Final slope preparation is by diver handling of a smaller Toyo pump to reduce and infill levels to specified slope tolerances of ± 0.45m.
