West Wharf Slab Replacement, Millbay Dock
For Associated British Ports Ltd
The existing suspended jetty at West Wharf is in part over 100 years old and exhibiting significant deterioration of the structural slab and supporting concrete structure. The underside of the suspended slab and secondary beams have suffered from fairly significant spalling of the concrete, allowing the lower, corroded reinforcement to be exposed to the marine environment. West Wharf is an operational berth, used principally by Brittany Ferries for their Plymouth-Continental ro-ro ferry services. The scheme involved the replacement of the existing 131m long by 18m wide upper concrete jetty slab with a new reinforced concrete slab spanning to the primary supports of the underlying reinforced concrete structure
