The world’s number 1 automated topographic solution

Sixense Oceania

CYCLOPS™ is a high-performance geodetic monitoring solution for continuous 3D deformation monitoring of structures and surfaces.

With more than 2,000 units deployed globally, CYCLOPS™ is the world’s number 1 automated topographic solution in terms of projects completed and quality of results.

Cyclops™ Features

Hardware agnostic

CYCLOPS™ is a suite of patented drivers and processing modules for operating and enhancing commercially available Total Stations.

Sixense's strong partnerships with vendors enables powerful and cost effective packages for our clients.

Hardware agnostic

Group operations

A unique and powerful feature of CYCLOPS™ is its ability to operate multiple systems as a group where data from all units is processed globally yielding un-rivalled accuracy. It allows for monitoring large areas or complex configurations with the guarantee to deliver the required level of data quality.

No wonder CYCLOPS™ is the preferred choice of the construction industry for real-time deformation monitoring of structures such as tunnels, shafts, caverns, retaining walls, roads, railway tracks, etc…

Group operations

Enhanced & controlled accuracy

Obtaining accurate measurement when commissioning the instrument is one thing, but keeping the same level of accuracy when the environment and conditions are dramatically changing is another challenge.

With CYCLOPS™, control parameters are followed in real time and adjusted as required to maintain the highest level of availability and accuracy.

Enhanced & controlled accuracy

Versatility without compromising accuracy

Standalone or in a networked group, with or without prisms, fixed or mobile, installed in unstable areas or not… the capabilities and versatility of CYCLOPS™ are such that it can cope with almost any situation without jeopardising performance.

An excellent example of this, is the global monitoring of caverns for the Melbourne Metro station construction where the configuration is complex and changing daily.

Projects using Cyclops™

Westgate Tunnel

Sixense has been awarded the comprehensive monitoring (Geotechnical, Structural & Environmental) of the tunnel section and environmental monitoring of the freeway & bridge sections.

To monitor the instrumentation, a site-wide radio network has been established and used in conjunction with hundreds of wireless self powered dataloggers.

For structure and deformation monitoring Cyclops is deployed to monitor the 3D deformation of retaining walls, structures and roadways.

For geotechnical monitoring a large array of instruments are installed, including ground water piezometers and inclinometers.

Melbourne Metro Tunnel

The Metro Tunnel is Melbourne involves constructing 9km of twin rail tunnels and five underground stations from North Melbourne through to the Domain precinct, via the CBD. The two stations caverns in the CBD are complex, each involving multiple shafts, entrance-ways, and adits, which are constructed with minimal disruption to the bustling city above.

Sixense is using CYCLOPS to provide automatic real-time deformation monitoring of structures and buildings. A significant achievement, and a first-of-a-kind, has been the real-time monitoring of the interior cavern construction using a complex group of networked Cyclops, allowing reference data to be transferred along the cavern to provide data with sub-millimetre precision.

Williamstown Railway Line

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.

City Rail Link - C1

The City Rail Link is the largest transport infrastructure project ever to be undertaken in New Zealand. It includes a 3.45km twin-tunnel underground rail link up to 42 metres below the city centre transforming the downtown Britomart Transport Centre into a two-way through-station that better connects the Auckland rail network.

The Contract 1 (C1) consists of the construction of the tunnels under the Chief Post Office and involved a load transfer of the supporting columns of the building allowing for excavation underneath. It required real-time monitoring with millimeter accuracy to guarantee the integrity of the heritage structure.

City Rail Link - C2

The City Rail Link (CRL) consists of twin 3.4km long tunnels up to 42m below the city streets to create an underground rail line linking Britomart and the city centre with the existing western line near Mt Eden. The Contract C2 involves the construction of 350m of twin cut and cover tunnels along Albert Street.

SIXENSE has been engaged by Connectus and Auckland Transport to monitor the construction works, and to provide assurance for Albert Street’s property owners and insurers.

The monitoring network consisted of a network of 9 Cyclops, 12 automatic inclinometers, dozens of ground water piezometers, and hundreds of strain gauges. The Cyclops network monitored building prisms and ground surface points 24/7 with sub-millimetre accuracy. The automatic inclinometers and strain gauges monitored deflections of the retaining walls and strut compression, and the piezometers measured ground water levels around the site.

Level Crossing Removal Project

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.

City Loop tunnels

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.
