Demolition of King Street Car Park
We are demolishing the multi storey car park at 92 King Street due to its age and poor structural integrity, and concerns around public safety. Every effort is being made to minimise disruption to neighbouring businesses and residents. Works began in September 2021 and are expected to be completed in July 2022.
Our work includes:
- Demolition of the seven-storey car park, including the Laing Street skybridge and King Street entrance ramp.
- Disconnection of services, and protection of the Ausgrid Substation located in the building's lower floor.
- Removal of all hazardous and demolished materials.
What have we done so far?
We began work in September 2021, establishing the site and wrapping the building with stretch plastic to create negative air pressure within the structure. This helped us safely remove materials containing asbestos from the site.
We have removed more than 13,000 asbestos former pods and have installed three acoustic shelters around the rooftop diesel generators.
We have also finished installing a 60-metre protective reinforced concrete culvert over the high voltage cables servicing the substation in the basement and a protective structure around the substation. We have also finished removing 3,250 tonnes of contaminated soil from the building's basement area.
What's currently underway?
We have started hard demolition work of the seven storey structure. This has required the closure of Morgan Street and Laing Street to traffic and pedestrians, as well as the pedestrian stairway from Morgan Street down to Laing Street.
There will be an increase in heavy machinery movements and an increase in traffic control to help manage the movement of plant, local traffic, and pedestrians. Hard barriers and site fencing will also be erected to delineate the areas of restricted access. We appreciate the community's understanding and patience during this time.
This hard demolition process should be finished in July.
Hard demolition commenced in May 2022.
Hard demolition progressing well in June 2022.
Once the demolition is complete, the ground floor slab along Laing Street will be left in place, and exposed earth sections of the site will be sealed to prevent run-off and minimise dust. To protect the site, it will be fully fenced with a 2.4m plywood fence.
We expect the project to be finished in July 2022.

Frequently asked questions
An Asbestos Removal Control Plan (ARCP) and an Asbestos Management Plan have been developed to ensure that adequate safety measures are in place. During removal of the asbestos pods, each zone will be sealed with plastic wrap.
Signs and barricades will be in place to clearly identify the asbestos work area.
Specialist environmental and hazmat consultants are engaged to review the plans and undertake assessment of risk controls on site during the works. This includes daily air monitoring to identify any airborne asbestos fibres throughout the perimeter of the works area.
At completion of the works, this consultant will perform an asbestos clearance inspection.
Safe pedestrian access is established along the east side of Thorn Street, and down the stairs to the east of the site.
During removal of the asbestos pods each zone is sealed with plastic wrap. During hard demolition of the remaining concrete structure, the building will be fully scaffolded and draped in mesh. Excavators using water sprays will also limit dust production.
Like with many projects across the city, COVID-19 has impacted work progress on this site and we have experienced some delays with removing the asbestos containing material pods. The work involved to remove these pods can generate significant noise.
To help manage the intensity and frequency of the noise, the contractor has introduced the following measures:
- The work to remove the pods will not take place at all on Saturdays, or between 12pm and 1pm Monday to Friday.
- The upper levels of the car park have now been decontaminated and the rooftop generators will be moved inside of the building structure meaning they won't be heard as easily.
Once the pods are removed (estimated to be by the end of March) there will be a significant reduction in noise levels. The rooftop generators will be decommissioned, and the works will go into a quieter phase while we conduct decontamination and protective works in the basement area. These works will finish in early April.
Noise monitors are in place around the site and will be monitored by an Acoustic Consultant. Recent readings have shown that the noise does not exceed the 75dB limit set by the Development Application.
Excavators using shears will be used to reduce noise. These replace traditional jack hammering techniques which are noisier.
Vibration monitors have been installed around the site to protect surrounding heritage structures and the Ausgrid substation. These monitors have been set to alarm if vibrations exceed stated tolerances.
Works will be undertaken between 7am and 5pm on Monday to Friday and between 8am and 1pm on Saturdays.
All trucking movements are via Thorn Street.
Works will be undertaken between 7am and 6pm on Monday to Friday and between 8am and 1pm on Saturdays.
