Case study:
Zero reportable instances!

The challenge

Pro-actively and efficiently manage the environmental impact of noise and dust.

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.

The SEPA team was looking for a new and innovative solution to help them adjust dust and noise levels on their site in a proactive and efficient manner.

The solution

Accessing live and continuous data on noise and dust anytime and anywhere with SiteHive.

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.


Benefits and features

Automated alerts and live information

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.

With this proactive approach to managing environmental impact, the project has had zero reportable noise instances.

Graphical data, DoA maps and images make it easy

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.

Confident decision-making

SiteHive gives the team a lot more certainty and confidence in their decisions. Because the devices are monitoring continuously, 24/7, they are able to do a lot more monitoring, and so always know what’s happening.

Another big advantage is the immediacy of the information. All the monitoring information, which includes live graphs, images, sound maps and weather, is available through SiteHive in one dashboard. This makes it easy for the team to see what’s happening in real time.

Accessible from anywhere, on any device

Because SiteHive can be accessed from anywhere, the team doesn’t need to be onsite all the time. They can monitor the site from wherever they are working and, because information is provided in real time, attend the site quickly if they need to take action.

The project currently uses 3 SiteHive Hexanodes across the site. The devices are highly mobile, and the team moves them around in line with their specific work requirements.


The Laing O'Rourke team said, "The SiteHive solution has been estimated to reduce the cost of managing environmental impact by 50% or more, providing an efficient, economical solution to a traditionally manual process. This means we can be better at how we manage our environmental and community impact. Placing this technology in our environmental team’s fingertips enables our people to be more agile, building better trust in our clients and communities."

"During the course of the work we have had zero reportable events. Using SiteHive we can see exactly what’s causing an issue, and address it immediately if we need to.
We are able to work proactively and minimise the impact on the environment and local communities."

"With SiteHive it’s instantaneous, the immediacy makes it much more meaningful as we can deal with things straight away. And having everything together in one place, even including the weather, makes it a lot easier. We can see the full picture and understand what’s happening across the site."
