The scheme involved the construction of an offshore rock breakwater containing more than 150,000 tonnes of locally produced rock core and armour, plus the infilling of 240,000m3 of dredged sand. Dredged sand was collected from a licensed area in Morecambe Bay and discharged hydraulically behind the breakwater via a 750mm diameter delivery pipe, which extended 1km out to sea to a mooring buoy, at which the dredger berthed. The total area of reclamation was approximately 40,000m2 of which a third received permanent full construction of a stone capping layer, stone sub-base, dense bitumen macadam road base with 80mm key-block paving in order to take the heavy duty port traffic.
