River Hamble Seawall Refurbishment
Client – Hampshire County Council
Value – £100,000
Duration – 6 Weeks
Type – Seawall refurbishment
This project involved the refurbishment of the seawall at The River Hamble Harbour Master’s Office.
Suttle Projects were in the Principal Contractor role to Hampshire County Council. It was a challenging project because of the tight working area which is within a very popular public amenity. This meant that a lot of forward planning was required and good communication with the local stakeholders to minimise disruption to them whilst also being able to complete the job efficiently.
In order to complete the refurbishment of the seawall the works also involved the temporary installation of a sheet pile cofferdam. The purpose of the cofferdam is to lengthen the available tidal working window and provide a clean working area.
The permanent works involved casting an in-situ concrete face to the existing wall. The face features a number of innovations to encourage bio-diversity such as the use of a textured formliner and rockpools of various shapes and sizes to mimic a natural rockface. Due to the sensitive marine environment, it was necessary for Suttle Projects to collaborate with the Harbour Authority’s Environmental Manager, which included mitigations such as bog mats to protect the riverbed silts, raking surface sediments to allow crabs to evacuate the works area and strict pollution controls.
