Liberty was engaged to execute the early works contract for demolition and remediation on the site that will host the new Powerhouse Museum, Parramatta NSW. The project site was classified as a historic and culturally sensitive site. The scope of works included demolition, soil remediation, new build works, demolition of an existing multi-storey car park structure, non-heritage elements of St George Terrace and the decommissioning of an electrical sub-station including rerouting existing services and utilities.
Robust solutions
- Liberty Industrial supervised and managed a third-party archaeological team to undertake an extensive European and Indigenous archaeological investigation. 15 European archaeologists and 5 Registered Aboriginal Parties (RAPs) conducted investigations on site.
- Our project team also coordinated the provision of all plant and equipment such as the design, fabrication, and construction of a specialised water screening bath used to screen some of the finer material excavated onsite.
- Liberty Industrial’s owned and operated 48t and 38t excavators to simultaneously break down the bulk of the car park structure, while a 25t excavator with a concrete cracker attachment was used to help with concrete processing and the demolition of small structures.
Exceptional outcomes
- We removed approximately 12,000t of concrete and 400t of steel for off-site recycling. In addition, Liberty Industrial completed site remediation works to render the site clean for future museum development and public access.
- Liberty Industrial’s team worked collaboratively with the RMS and the Heavy Vehicle National Register to transport plant and equipment on-site and deliver the works with little disruption to the adjacent community.
- The project was delivered successfully with a sustainable, safe and efficient outcome.
