University of Sydney -
Jones St Utility Expansion

Certus Projects was engaged to design and construct an infrastructure expansion trench for the University of Technology Sydney (UTS). The works involved the installation of underground services to establish a new utility connection between UTS Building 10 and existing infrastructure in Building 7.

​

This upgraded utility link enhances the long-term reliability and performance of the university’s water infrastructure. The project was delivered in two carefully planned stages, prioritizing safety and minimizing disruption to students, local residents, and surrounding traffic.

​

Key Features:

• Steel fabrication and installation at varying depths and bends to meet the design requirements and provide allowances for the shafts next to the buildings.

• An insulation process involving specialised mechanical pipes were used to maintain the water temperature underground. Additionally, waterproofing systems and hydrostatic testing were performed at regular intervals for 24 hours to ensure works were successfully installed.

• Access and egress to construct on an extremely busy pedestrian area of the University.

• Creating a flushing loop for chemical treatment of the water pipes before commission
