Southpoint Redevelopment

Monitum used automated infrastructure monitoring to mitigate the risk of damage to critical infrastructure corridors during the $600M Southpoint development.
This project lasted 24 months and was a sensitive and complicated construction challenge. Foundations for three new buildings were being constructed beside critical transport corridors and a 128-year-old heritage-listed Brisbane landmark. During development, builders raised the 330 tonne Collins Place approximately 800mm from its original location.
Because the neighbouring deep excavation could de-stabilise rail infrastructure and cause significant delays. Queensland Rail engaged Monitum to monitor South Bank Station, one of Brisbane’s busiest train stations. Furthermore, Monitum also monitored Melbourne Street tunnel during development.


How we did it

Monitum undertook heritage monitoring on the building, attaching equipment and sensors to critical points of the structure. This provided multiple layers of protection against damage to the asset during construction.
For South Bank Station, Monitum used a real time notification and alerting system. This system immediately reported any displacement of an asset to project staff and rail network control. This was an optimal solution for the client and Queensland Rail. The system required occasional maintenance, with it now used on similar projects across Queensland.
Melbourne Street tunnel presented a unique challenged for our sensors and equipment. Changing atmospheric conditions and interference from electrical devices occurred within the tunnel. Despite this, Monitum achieved observations of 2-4 mm inside the tunnel.



Through the lifetime of the project, Monitum’s automated infrastructure monitoring proved vital to not only the primary contractors on the project, but also asset holders in the surrounding area.
Our equipment took continuous measurements from all sites during the 24 month period. This involved monitoring railway lines, tunnels and buildings to provide accurate data for the Monitum team to analyse data remotely. With the team looking for potential movement or cracks originating from nearby excavation.
The use of Monitum’s automated monitoring solution enhanced the safety on site and of surrounding assets. While providing valuable information to primary contractors allowing them to make informed decisions about their construction project.
