About the Project

ADDRESS 153 Macquarie St, Parramatta

VALUE $50 million


Part of the $2.7billion Parramatta Square development, this site is located in the centre of Parramatta, the project comprises three commercial towers and shared community areas.

Mainland were engaged on an early works package to remediate the 3 hectare site, install over 8000m2 of diaphragm wall up to 15m deep and then bulk excavate over 300,000m3 of various materials.

The site provided various challenges including works next to heritage buildings, various stakeholders and consistent interactions with local authorities and neighbours. The close proximity to the rail line required constant monitoring and co-ordination allowing for minimum deflection and movement during the excavation process.

Various contaminated materials, including asbestos, acid sulphate soils, general solid waste and diaphragm wall spoil were removed. Mainland Civil were able to segregate materials and manage the excavation work to minimise the quantities of these materials requiring offsite disposal and hence minimising costs for our client.

The site also involved stage at handover to builders throughout the project requiring coordination of shared access and areas.

Mainland were able to work with the client and nominated builders to achieve optimal outcomes for all stakeholders.
