The project consisted of the refurbishment of a 70 metre long section of the 1963 coastal defence using a similar construction methodology as that of the existing defences constructed between 2000, 2003 and 2011. Following demolition of the existing gabion defence, new “A” frames were erected at 1.80 metre centres comprising rectangular reinforced concrete members tied together with hardwood sections.
Double layered galvanised steel mesh was fixed between the concrete members and rock armour placed behind the mesh.
The demolition arising’s were used as fill material behind and below the new works and the leading edge of the sand dunes were re-profiled and a granite rock armour capping was installed along the length of the wall.
The works were carried out between high tides which were also affected by high winds and atmospheric pressures to increase the predicted heights.
The Fitties beach is a popular amenity beach, green space and within the Humber Estuary Site of Special Scientific Interest (SSSI).
