Sydenham Metro Upgrade Monitoring
The Sydenham Metro upgrade (SMu) project forms part of the Sydney Metro City & Southwest project and includes upgrades to Sydenham Station, the surrounding network and other ancillary infrastructure to accommodate Sydney Metro trains. Sydney Metro is Australia’s biggest public transport project.
The challenge
During a stage of the SMu project that involved under-bore tunnelling to run utility cables under the rail track, it was vital to understand if the works were causing even the slightest changes on the track bed.
Our solution
Working closely with principal contractors John Holland and Laing O’Rourke, along with the client Sydney Metro, we recommended and then installed a wireless automated monitoring platform to measure for any track movement. The solution included 43 tilt sensors and 12 optical displacement sensors along with the gateway. The sensors connected wirelessly to a solar-powered gateway that transmits the data for analysis.
Benefits
The solution, which was fast and easy to deploy, delivered 24-hour live reporting, as well as access to the data from anywhere with an internet connection. All stakeholders could readily gain access to the reporting data, including the client and the construction crews on site, around the clock, to mitigate potential risks and ensure the safety of all stakeholders.
