pdp Green

Royal William Yard

Sea Wall and Inner Basin, Plymouth

pdp Green undertook investigations, civil engineering design and project management of remedial works and refurbishment of 800 metres of dock walls and inner basin.  The structures dating from the 1830’s are of granite and limestone construction and are classified as an Ancient Monument. Investigations included assessment of water flows behind the wall in relation to tidal movements, the competence of old backfilled materials, the adequacy of foundation conditions, and underwater trial pitting of the seabed/sea wall interface.

The works designed by pdp Green included mortar injection pointing, back wall grouting of retained soils, fender replacement and some underpinning works.
