A 35m extension to the existing ferry pier and upgrading of fendering to suit the new ferry MV Loch Seaforth. The main aim of the project was to eliminate disruption to ferry services during construction. The chosen solution was a 3500t concrete caisson constructed in a dry dock, floated into position with fenders attached. No ferry services were disrupted during the 8 month construction period. The works included dredging, formation of an underwater rock bund, underwater concrete foundation, reinforced concrete caisson construction, fendering and scour protection.
