A number of sensitive infrastructures exist along the path of West Gate Tunnel project, which require monitoring to ensure their safe and continued operation, one of which is the Williamstown railway track.

Sixense has installed a Cyclops system to monitor the displacement of the Williamstown railway tracks in real-time. Prisms are installed and monitored to ensure track movement is within tolerances, with data sent wirelessly to Geoscope for data visualisation and reporting. Any movement of track monitoring prisms exceeding set thresholds will automatically trigger alarms to be sent to the stakeholders involved.

The North East Link (NEL) is Victoria's largest road project, designed to connect the Eastern Freeway to the M80 Ring Road, completing Melbourne's orbital freeway network, reducing congestion, and improving travel times.

A key component of this project, known as the North Package, focuses on upgrading a 5-kilometer stretch between Watsonia and Greensborough. This package, led by the M80 Ring Road Alliance, aims to deliver new lanes, enhanced interchanges, safer road features, bridges, and pedestrian and cycling paths, all to support traffic flow and accommodate future regional growth.

With advanced monitoring technology and efficient execution, Sixense plays a crucial role in maintaining rail stability and meeting the project’s standards. The integration of real-time data and automated alerts provides essential support, contributing to the ongoing progress and success of the North East Link North Package.

Logan Water and the City of Logan Council partnered with Hollcon Construction on the Loganlea Railway Station Relocation Project to address growing infrastructure demands and meet health and safety standards. The project involved relocating a water reticulation pipe using microtunneling beneath the Queensland Rail Beenleigh Line near the Loganlea Road Overpass. A 600mm-diameter steel casing pipe was successfully installed over a distance of 80 meters using advanced trenchless techniques, minimising surface disruption.

Sixense Oceania was engaged to monitor the safety and stability of the rail tracks throughout the project. Utilizing a solar-powered Automated Total Station (Cyclop) and 36 track monitoring prisms, the company provided real-time rail monitoring during construction. The Beyond Monitoring software facilitated live data visualisation, automated alarms, and detailed reporting, supporting informed decision-making and risk mitigation. Despite challenges such as tight scheduling and limited site access, the innovative monitoring solutions and precise execution ensured compliance with safety standards, efficient coordination, and on-time project delivery.

The New M5 tunnel is Stage 2 of WestConnex, Australia’s largest integrated transport and urban revitalisation project and is being delivered by Sydney Motorway Corporation (SMC) on behalf of the NSW Government.

Sixense has designed and installed a system to monitor track deformations in real-time during adjacent tunnel construction works. Our patented Cyclops system is measuring track-parameters, such as top, line, cant and twist with millimetric precision, and sending real-time alarms to stakeholders when set thresholds are exceeded.

The Victorian Government is removing 75 dangerous and congested level crossings across Melbourne by 2025, the largest project of its kind in Victorian history. The level crossing at Glenroy Road, Glenroy is being removed by lowering the rail line under the road.

Sixense have installed structural monitoring sensors, including monitoring prisms, tiltmeters and crackmeters, on sensitive infrastructure adjacent to the works and is providing real-time monitoring, with data, sensor exceedance alarms and reports available in Geoscope.

Additionally, Sixense is providing environmental consultancy services to optimise the works and provide mitigation measures where applicable. Environmental monitoring is also being carried out using noise and vibration sensors, with data available in Geoscope.

The Breakfast Creek Sewer Augmentation Project involves the construction of a new 1.8-metre diameter trunk sewer pipe over a one-kilometer distance, stretching from Bowen Hills to Windsor.

Sixense has been contracted to develop and execute a monitoring system aligned with Queensland Rail's specifications. A Rail Infrastructure Monitoring Action Plan (RIMAP) has been devised to tailor the installation of an automated monitoring system. This enables real-time monitoring as the tunnel boring machine (TBM) advances over the sensitive rail lines during construction.

The construction of the State Library Station Cavern of the Melbourne Metro Tunnel project involves mining twin nozzle tunnels that come within less than 1m of the existing City Loop tunnels, which are critical to the smooth running of Melbourne's entire public transport network and must not be impacted in any way.

Sixense has installed its patented Cyclops system in each of the four City Loop tunnels for the monitoring of tunnel deformation in real-time. Displacement data with sub-millimetre precision is delivered to our client in real-time whilst trains continuously travel through the tunnel, ensuring all stakeholders that tunnel construction works are not impacting the safe operation of existing passenger train services.

Work is underway to rejuvenate the rail line in Northland, which includes replacing five bridges and lowering the tracks in 13 tunnels to allow larger sized shipping containers to be carried on the line. KiwiRail has contracted Sixense to provide real time convergence monitoring of the tunnels along the rail line.

Due to the remote locations of the tunnels, a wireless solution with real-time data transfer has been proposed. At each tunnel, a number of convergence arrays has been installed consisting of laser distance meters installed to measure convergence of the tunnel shoulders and crown. Data is displayed in Geoscope, with real-time alarms triggered and sent to key stakeholders when set thresholds of convergence are exceeded.

The City Rail Link (CRL) Contract C6 involves storm water diversion works in Mt. Eden for the construction of a new underground storm water tunnel between Water and Nikau Streets. Sixense has been selected to install and monitor groundwater and structure deformation sensors during micro TBM works.

Deformation monitoring included deploying Sixense's patented Cyclops system to monitor KiwiRail railway tracks in real-time, which included calculation of track parameters, such as gradient, cant, twist, vert and horz. Groundwater monitoring was conducted wirelessly using a proprietary site-wide radio datalogging system. Geoscope was used to display data and generate reports, where any sensor reading exceeding set thresholds will automatically generate alarms that are distributed to all stakeholders.
