Project summary

Incorporating our alternative cantilevered solution, we were responsible for the design and reconstruction of the town Quay in the Suffolk town of Lowestoft.

The £3.5m programme, on behalf of Associated British Ports (ABP), comprised of a new quay wall, surfacing and associated features, the removal of scoured material from the river bed and all associated works.

The detail

Identifying an innovative long-term solution, we proposed an alternative cantilevered design, which featured a combi-piled wall with 1.2mø tubular piles, the toe level set at 17mOD and precast capping beam at +2.75mOD.

Successfully awarded the contract on this basis, we took the lead in design development and formally issued drawings to ABP via our collaborative 4Projects software. Beginning with piling works, the construction phase involved the reconstruction of 202m of the Town Quay wall and the reconstruction of drainage, including outfalls to drains running from the outside of the port estate.

Due to the proximity of adjacent buildings and the condition of the remaining existing quay wall, approximately 140m of the new wall was constructed from floating plant equipment with a land-based crawler crane utilised to construct the remaining 60m. Additionally, we completed the reinstatement of the hard standing to the immediate rear of the wall and also made provisions for the existing services and utilities within the quay.
