The Cranbourne Line Upgrade (CLU) is delivering major rail upgrades as part of Melbourne's Level Crossing Removal Project (LXRP). Separated into two packages of work, Package B includes building new railway tracks, the rebuild and upgrade of Merinda Park station, and a new pedestrian underpass for rail users. This work is being managed by the South Eastern Program Alliance (SEPA), a grouping that includes Laing O’Rourke, Jacobs, LXRP and Metro Trains Melbourne.
To manage environmental impact across this large site, the project team is using SiteHive. They deployed SiteHive Hexanode digital monitoring devices to give them access to live and continuous data on noise and dust, and use SiteHive software to manage information.
The SiteHive Hexanode devices allow the team to monitor noise and dust in real time. Small in size, the devices use innovative technology that includes direction of arrival sensors, multiple cameras and sophisticated digital microphones. These provide sound maps, direct images and audio files when thresholds are exceeded - allowing the team to see exactly what is causing events.
Automated alerts and live information allow the team to act quickly
If a threshold is triggered, SiteHive automatically alerts the relevant SEPA team members via sms and email. They can then immediately use SiteHive to see what’s happening and investigate the issue.
The images, audio and direction of arrival maps are presented graphically in SiteHive so they are easy to understand. They allow the team to identify sources of noise and dust quickly. For example, they can see if noise was made by a train, traffic or wildlife, rather than project construction work. And if it is a project site issue, having access to all the information means they can address the problem immediately.
With this proactive approach to managing environmental impact, the project has had zero reportable noise instances. Environmental Manager Kory Wright says....
