Circular Quay Investigations


Project overview

The NSW Government is planning to renew the public spaces and transport infrastructure surrounding the Circular Quay ferry wharves.

As part of this work, Transport for NSW (TfNSW) conducted initial investigations at Circular Quay in 2018 and is continuing these investigations between June and September 2020.

Key benefits

  • The investigations will provide data to understand how the wharves and public spaces might be renewed
  • Circular Quay will remain open for business during the investigation work
  • All ferries and trains will continue to operate.​

Project Status​​​​

Investigations will commence from 22 June, 2020 with information collected using the following methods:

  • Geotechnical and geophysical investigation
  • Surveying to map existing structures and physical features
  • Locating services and utilities in the area

The investigation work will help to understand what lies beneath the surface and map the features of Circular Quay.

Work will involve:

  • Drilling up to 12 boreholes near the entry to Circular Quay Station, on the eastern and western section of the promenade (at ground level under the Cahill Expressway)and in First Fleet Park (subject to approval)
  • Investigation work under the promenade adjoining the Circular Quay wharves using a small boat at night
  • Soil sampling in First Fleet Park.

Investigation work at each borehole location will take up to 48 hours.

Some drilling activities will be undertaken at night to ensure we avoid peak times and minimise impacts on pedestrians. Drilling of boreholes may lead to some noise.
