Sea Wall to be restored

Farm Cove’s 150 year old Sea Wall to be restored

The restoration of the 150 year old Farm Cove Sea Wall, completed in 1878, commenced on Wednesday 24 July 2013 at the Royal Botanic Garden, Sydney.

The works will safeguard this important and historic feature of Sydney’s famous promenade from the Opera House to Mrs Macquarie’s Chair, arguably providing the city’s most highly-prized view of Sydney Harbour for both locals and tourists.

'In order to rectify structural instability and deterioration in the sea wall, we will first dismantle it, then construct a new footing using piles and a concrete ground beam. The wall will be rebuilt on the new footing with existing, repaired and cleansed sandstone blocks to maintain its aesthetic,' said Gary Hinchliffe, Project Manager and Trust Acting Manager of the Domain and Infrastructure.

This latest initiative follows a significant program of works undertaken in the late 1990s to stabilise an adjoining section (approximately 50 per cent of the total length) of the wall.

The repair works will address the underlying causes of two major faults: one, along a thirty metre strip on the eastern side of the wall and then the second, along the western side. This will prevent instability and ensure the wall’s long-term structural integrity and continued public safety.

The three major steps will involve deconstructing the pathway on the landward side of the wall, its reconstruction and reinstallation of a new pathway.

'The works on the western side of the wall will be similar to those on the eastern side, but will require just over 100 meters to be completed by December 2013. This will also require the closure of the sea wall path with pedestrian and traffic diversions in place,' he said.

'After the construction compound is installed there will be no access along the sea wall north of Fleet Steps to and from Mrs Macquarie’s Point until mid October 2013. Pedestrian and vehicle diversions will be in place either via the middle western path for pedestrians or Woolloomooloo sea wall path for vehicles,' Mr Hinchliffe said.

'We realise the unfortunate impact in regards to public access, but these restoration works are essential to ensure the integrity of the sea wall and pathway,' he said.

Signs will be installed along major access points of the Garden to inform the general public.
