The Thames-side barge wharf at Rainham had been constructed following the Second World War using some of the floating roadway units that had returned from the Mulberry Harbour. Facilities at the wharf needed to be modernised to accommodate large self-discharge dredgers. The imported gravel is much needed for construction.

Beckett Rankine inspected the marine facilities and designed strengthening to the existing dolphins. New dolphins were also designed to support a replacement pontoon and a new conveyor system. A check was carried out on the flood wall in the area of the new stockyard.
