CODCD Enabling Works

The CODCD Enabling Works project was an integral part of the Centre for Obesity, Diabetes and Cardiovascular Disease (CODCD) development at the University of Sydney's Camperdown Campus. Located adjacent to the Royal Prince Alfred Hospital (RPA), the project site was formerly occupied by the Missenden Buildings. DECC was engaged as the Principal Contractor to deliver a comprehensive scope of works, including the demolition of redundant buildings, service relocations, road construction, and Early Contractor Involvement (ECI) for additional works. The project required meticulous planning and execution, particularly given its proximity to the busy hospital and university environment.

Demolition of Redundant Buildings: DECC was responsible for the demolition of up to five-storey buildings that previously occupied the site. The demolition process included a complete internal strip-out, hazmat removal, and structural demolition. Hydraulic attachments such as hammers, pulverisers, shears, and grapple attachments were used to safely dismantle the structures. Concrete and brick were separated and processed onsite using a mobile crusher and screen to produce a 40mm minus product, which was reused in road construction.

Service Disconnections and Relocations: The project involved the disconnection of essential services, including power, water, gas, and communications. DECC also managed the relocation of a 900mm diameter stormwater line and a Jemena gas main, ensuring minimal disruption to ongoing campus and hospital operations. This work included the handling of asbestos-contaminated material (ACM) within the soil during excavation, as well as the installation and backfilling of new service lines.

Road Pavement Construction: DECC constructed a 200-metre rigid pavement dual carriageway using onsite recycled material for the sub-base course. The road construction also included the realignment of Sir John Hopkins Drive, which involved the installation of new kerbs, gutters, and an asphalt wearing course. The recycled material from the demolished buildings was utilised to build up the subgrade, allowing for a 150mm layer of dense graded base (DGB) and a 200mm thick reinforced concrete pavement.

Pit 9/10 Junction Construction: As part of an ECI process, DECC was awarded additional works for the design and construction of Pit 9/10 junction. This involved the excavation of the pit, construction of a structural perimeter contiguous piling system, installation of a steel retention and bracing system, and the construction of an in-situ fibre-reinforced polymer (FRP) pit base, all in accordance with Sydney Water-approved designs.

Environmental and Landscaping Works: The project also included the implementation of environmental controls, such as sediment fencing and tree protection, as well as soft and hard landscaping works. This involved planting trees and shrubs, constructing walkways, and installing lighting, all designed to integrate seamlessly with the surrounding university and hospital precinct.
