Liberty Industrial offer demolition and remediation services to the land development and building and construction sectors for large scale development and infrastructure projects, whether your project involves the removal of a single structure or piece of infrastructure or the remediation and reinstatement of an entire brownfield site in preparation for redevelopment.

Case Study: Moorebank Intermodal Terminal Early Works

The Moorebank Intermodal Terminal is major infrastructure project in Western Sydney that will see container freight from the Port of Botany transferred to the site for subsequent loading to trucks in proximity to major transport routes including the M5.

On completion the project will see the removal of approximately 2500 truck per day off roads between Botany and Western Sydney.The facility is being constructed on the former Department of Defence Military School site on Moorebank Avenue. The site is approximately 70Ha and contains over 250 buildings that are required to be demolished prior to construction works commencing. Liberty Industrial has been engaged by Sydney Intermodal Terminal Alliance to carry out the Demolition and Remediation Works package.

The demolition works include the demolition of more than 250 buildings including the identification and removal of hazardous materials and the removal and disposal of all associated in ground infrastructure including existing pavements, hardstands, civil infrastructure and utility services.

The project also involves the remediation of identified sources of contamination including storage tanks, waste pits, waste stockpiles, asbestos impact materials,organochlorine pesticides, polychlorinated biphenyls and hot spots that are located in various locations across the site. This includes the removal and remediation of nine large underground storage tanks located across the site and the remediation of former site tip areas that contains in excess of 80,000m3 of deleterious and contaminated fill.

The remediation strategy includes bioremediation of TPH impacted soil, excavation, sorting segregation, reclassification, disposal and beneficial reuse of impacted fill. Asbestos impacted soils will be remediated through a combination of ‘hen pecking’ for reclassification where practicable, and offsite disposal.

Other works required under the contract include making good and maintaining existing boundary fencing, maintaining site security, maintaining existing vegetation and implementing bush fire protection measures throughout the works.

Liberty Industrial is also undertaking heritage salvage and relocation works including the salvage of European and Aboriginal artefacts. The works include the cataloguing and dismantling of large structures for future reconstruction. Protection of these structures is also required during demolition and remediation of areas adjacent to these buildings.

Due to the high priority placed on the subsequent development and construction Liberty Industrial developed a program of work that included the establishment of six separate demolition, hazardous material removal and remediation crews working concurrently across the site.

In post tender consultation with the client we developed a strategy that broke the site into priority areas so as to enable separate validation and early handover for commencement of construction works

Case Study: Central Precinct Munitions Factories

Liberty Industrial carried out the Central Precinct Munitions Factories demolition project for Lend Lease in preparation for the Central Precinct residential development in Western Sydney.

The project involved the demolition of two large munitions factories and ancillary building structures, and the removal and disposal of all inground infrastructure including concrete floors, roads, hard stand areas, footings and services. The works included the removal of significant volumes of friable and bonded asbestos from the bitumen membrane beneath the metal roof and careful planning mitigated the risks associated with the potential for interaction with live munitions.

Liberty Industrial developed an alternative demolition methodology for the collapse of the two large munitions warehouse structures resulting in benefits to the project program and greatly reducing exposure to working at heights, which significantly minimised the safety risks involved with carrying out the works.

Case Study: Toshiba Warehouse Demolition

The project involved the demolition and remediation of Toshiba Australia warehousing and office facilities in Parramatta including car parking and landscaped areas in preparation for residential redevelopment of the site.

The scope of works included the demolition and removal of all aboveground and belowground infrastructure including the demolition and removal of all above ground structures and the excavation and recycling of in excess of 8,000 tonnes of concrete and asphalt pavements, and the removal of all shallow building foundations and redundant services infrastructure to 1.0m below grade.

The works also included the remediation of asbestos contaminated soil involving the excavation, stockpiling management and the disposal of 600 tonnes of asbestos containing soils.

Given the tight program requirements for the project Liberty Industrial mobilised one of our 120t Hitachi excavators with a Rotating shear attachment. This enabled us to collapse the 8m high precast concrete panel structures less than a week from commencement. We then deployed three machines with specialised demolition attachments including grab, pulveriser and shear attachments to process the demolished material for recycling.

Liberty Industrial recycled over 95% of the demolition waste. The large quantity of concrete demolished from the buildings and slabs enabled us to provide a cost effective solution to the client that included the crushing and screening of those materials.

Liberty Industrial produced in excess of 8,000 tonnes of quality recycled concrete product including a 30mm minus, a 20mm aggregate and a 40/70 aggregate for sale and brokered the sale of these products and stockpiled approximately 1000 tonnes of residual material on site for beneficial reuse on the building construction works. This option provided the client with a better commercial outcome than direct offsite disposal.
