Heritage Cases

Quay 3 is situated on the East Bank Multi-Purpose Terminal (MPT) in the port of East London. The quay wall in 378m long and has a draft of – 9.8m CD. The mass concrete gravity quay was constructed in the 1920’s and has since reached an advanced stage of deterioration. The quay has historically been used for berthing and offloading general cargo vessels. The quay wall is equipped with tyre fenders as well as bollards equally spaced at approximately 18.3 m centres. The Ferry Landing is situated at the west end of Quay 3 and has the same draft as the quay wall. The landing collapsed in 2019 and is to be upgraded. Quay 4 is 110 m long and has the same maintained depth as Quay 3. The total length of the combi-wall is 526 m. A FEL 2 prefeasibility study conducted in 2017 indicated that the current deterioration of the mas concrete wall was ongoing and likely to get progressively worse. Given the advanced state of deterioration, the ability of the structure to fulfil its functional requirement is uncertain. The options for rehabilitation of the deteriorating structure were complex. To clad or locally repair the structure would be impractical and would at best delay the continuous deterioration of the surrounding concrete. Before the quay wall can be replaced, it must be decommissioned first given its advanced stage of deterioration to ensure the structure can fulfil its functional requirement into the future. The decommissioning and replacement of the existing wall was the only practical solution that would provide certainty with regards to the future life span of the facility, address the adjacent Ferry Landing and alignment with Quay 4.
