Surveys are to be carried out on Alderney’s breakwater to see what needs to be fixed to ensure its future integrity.
The States of Guernsey – which has responsibility for the breakwater to cover the Bailiwick’s contribution to the UK’s defence budget – is looking for firms to carry out a Bathymetric Survey and and a ‘superstructure inspection and survey’.
The States are also recruiting a specialised stonemason for an eight month fixed term contract to work on the essential structure.
The breakwater was built in the mid 19th century, primarily as a military asset to protect British Navy ships and to protect the island from an invasion by France.
It also allows sheltered anchorage in Braye Harbour and protects the island from coastal erosion.
Its location and length mean it is vulnerable to the elements though, particularly during storms.
A visual inspection carried out after Storm Goretti hit the Bailiwick in January this year revealed some damage, and the extent of that will now be investigated by specialist firms.
A Bathymetric Survey would explore the depth and features of the sea bed around the breakwater and help assess what work needs to be done around the areas of the structure that are underwater.
A superstructure inspection and survey would assess the integrity of the breakwater including the elements of it which are above water.
Both surveys would help to identify cracks, subsidence, or other deteriorating aspects of the breakwater and help determine what work needs to be done to fix it.
Alongside this, the States of Guernsey want to appoint a ‘Breakwater Stonemason Supervisor’ on an eight month contract to work for the Committee for the Environment and Infrastructure in Alderney.
They will be responsible for the on-site supervision of the maintenance of the breakwater and associated buildings.
This role also includes responsibility for co-ordinating any ‘surface team’ works such as divers or other activities.

E&I recently announced plans are being put in place to enable fishermen in Alderney to use the breakwater slipway again, despite the ongoing work to identify and repair damage to the structure.
Anyone using the area is urged to remain cautious though, as there are still large holes on the lower walkway, which will be addressed “as the weather permits”.
There is also a risk of loose material falling from damaged sections of the upper wall to the lower walkway.
