Australian based geotechnical monitoring group Geomotion, has successfully come to a heads of agreement with SkyGeo for their cutting edge InSAR satellite monitoring technology to be used in Australia, Singapore, Malaysia, Myanmar and Indonesia.
Geomotion sees InSAR as complementary to existing instrumentation, not as a replacement, working so well together to offer their clients information that has previously been nearly impossible to obtain
InSAR stands for Interferometric Synthetic Aperture Radar and is a proven technique for measuring ground movements. Satellites record images of the Earth, and these images can be combined to measure movements of the ground surface.
InSAR is particularly useful for monitoring dynamic position changes. InSAR’s broad spectrum of impressive features allow for a new depth of insight for projects. A large number of measurements and weekly updates provide a detailed insight in the slope and speed of subsidence. A sudden drop of a small area might be a reason for local inspection. Wider gradual subsidence tells a different story.
InSAR allows for possible millimetre accuracy, measurements of areas as small as 100m2 up to 10,000km2 and up to 100,000 measurements per km2. Additionally, the data archive goes back to 1992 and covers 70% of the Earth’s land, meaning in some cases it is possible to have data dating back up to 25 years.
InSAR presents viable and important solutions across many industries, including Mining Stability, Tailings Dam Stability, Civil Engineering and Energy, including oil and gas projects both onshore and offshore.
Mining stability monitoring is a service to provide persistent geotechnical risk surveillance to identify areas of abnormal surface movement over time. Mines need to be up and running 24/7 and Geomotion helps achieve that goal by identifying instabilities early. By assessing time-dependent shape changes in InSAR data, geotechnical domain experts can identify patterns of instabilities.
This is a direct pathway to improve asset management in mining operations. Combined with strategically placed geotechnical or structural instrumentation a comprehensive monitoring plan is established.
Each mine has several areas of high geotechnical risk, that each require dedicated iterative assessment. Tailings dams pose a special category of risk. Because of environmental issues in the recent past, most mining experts are now looking for continuous monitoring systems to predict instability better. Solid tailings are often used as part of the structure itself and with the tailings being liquid or a slurry of fine particles within groundwater, significant instabilities arise in a variety of ways that are usually not completely understood. With InSAR, Geomotion can help with this understanding. We characterise and quantify these time-dependent degradation processes on a wide area scale and identify different dynamic patterns. Monitoring these patterns continuously is a proven permanent risk management method.
Geomotion/SkyGeo JV configures InSAR monitoring solutions for their clients, each with a graph of deformation over time. Risk management practitioners use this for predictive maintenance. Geomotion/SkyGeo JV monitors subsidence for many civil engineering projects in this way including roads, railways, dams, bridges, tunnels, airports, pipelines, neighbourhoods, sewage systems, buildings and water defence.
InSAR technology is available from the Geomotion/Skygeo JV now.

Albany Wind Farm is an 18 turbine wind farm with the southern hemisphere’s largest wind turbines. It has the capacity to meet 80% of Albany’s power needs.
Geomotion were appointed by WSP to provide a monitoring system for the farm. The aim of the project is to monitor the service life of the turbine foundations at Albany Wind Farm.
By installing tiltmeters on the base of three of the twelve turbines, WSP is intending to establish the extent of foundation movement, the extent of fatigue damage on the tensioned ground anchors and the extent of fatigue damage to the concrete foundation.
Geomotion installed two Biaxial Tiltmeters to each of the three chosen turbines at 90° angles form one another with the intention of monitoring the vertical movement of the foundation in four directions.
The sensors where glued to the base of each turbine mast using high strength epoxy resin glue, each covered with a protective metal vandal proof cover.
To allow the client to gain near-real time data of the foundation movement we attached these sensors to YDOC, Model number WL-N315ADS Data loggers. These loggers record the tilt on a 15 minute basis and provide a report email daily.
Premier Coal is situated in the Collie Coal Basin in the South West of Western Australia,
approximately 200km south-south-east of Perth. The mining operations are about 15km east of the town of Collie, which is situated in the jarrah forests of WA.
Premier Coal Mine produces a clean coal with low ash and sulphur content such that it does not need to be washed and requires only crushing, sizing and blending prior to use. The coal handling equipment installed at the Premier Coal Mine is very effective. The system has been designed to supply coal in a very consistent way so that there are no variations in quality.
The coal handling plant consists of a crusher, screening plant, stockpile stacker, reclaimer and delivering system for Premier’s customers, either by conveyor, rail or truck.
As part of Premier’s open cut pit monitoring, over 29 piezometers were installed in 11 locations across the area. Previously, the data was collected manually by site personnel.
Geomotion proposed the Loadsensing G6 Data Logging system to automate the collection process, including a 5-channel node at each location and a centralised gateway. The data is presented directly in Premier’s data management software.
This system fully automates the collection and presentation of piezometer readings, ensuring the data available for analysis is kept up to date at all times.
Mascot Towers is the high-profile residential building in Sydney that was evacuated in June 2019 due to serious concern about its structural integrity.
With the rapid growth of our cities and the increasing need for affordable housing, buildings similar to Mascot Towers are popping up quickly throughout Sydney and other major Australian cities.
Concerns were initially raised when significant cracking began to occur suddenly through the building’s basement foundations (see image below).
Geomotion were engaged by the remedial engineers to supply and install structural monitoring equipment on critical areas in the building's basement.
A site walkover was undertaken on the Monday morning after the evacuation, the same day Geomotion was first contacted. Sensors were installed and commenced sending live data to Geomotion Cloud, Geomotion's online data hosting platform, by the very next day.
Geomotion's precision monitoring systems can be utilised, not only after a major structural failure event, but also during construction and throughout a building's lifespan to provide critical information on a building's structural health, early warning alarms and peace of mind for all stakeholders.
Geomotion technicians carried out the installation of 4 tilt meters on critical areas on the basement slab, with four additional tilt meters set to be installed soon.
A 3G telemetry gateway was installed to enable data to be transmitted remotely – importantly removing the need to be inside the building to retrieve data.
Geomotion's data team set up the online portal on Geomotion Cloud, where data is displayed in easy to interpret plots.
Geomotion also integrated external survey data into Geomotion Cloud, offering the client a centralised platform to view all data, enabling them to make quick and informed decisions.

Description of Geomotion Works
Salini Impregilo S.p.A. - NRW Pty Ltd Joint Venture (SI- NRW JV) has entered into an agreement with Field Monitoring Services, Geomotion Australia, Land Surveys Joint Venture (FGLS JV) for the work of:
“SUPPLY, INSTALLATION, TESTING, OPERATION, MAINTENANCE OF GEOTECHNICAL AND SURVEY INSTRUMENTATION, INCLUSIVE OF MONITORING AND MIMS MANAGEMENT FOR FORRESTFIELD AIRPORT LINK PROJECT”.
Geomotion is working as a part of Joint Venture partner and broadly responsible for the followings works:
The Western Harbour Tunnel & Beaches Link is a planned north-south motorway along the current alignment of Wakehurst Parkway between Warringah Road, Frenchs Forest and the WestConnex motorway in Sydney. Up to 235 borehole sites will be tested in suburbs including Balgowlah, Seaforth, North Sydney, Neutral Bay and Cammeray. These investigations will feed into engineering design, final costings for the project and further route analysis.
As part of the geotechnical investigation, Geomotion was commissioned by AECOM to install Vibrating Wire Piezometers (VWP’s) at three inclined borehole locations along the proposed alignment. At each location, up to four VWP’s were installed at lengths of up to 160 m to monitor specified zones of ground water pressure. Each location was fitted with a Rippa 3G data logger with Stalker VW interface. Each of the four data loggers were custom designed and built to fit in the top of the borehole underneath a trafficable GATIC.
The data loggers have been programmed to upload hourly readings to a cloud based server. Data is presented showing fluctuations in water pressure (kPa), meters below ground level (mBGL), meters Australian Height Datum (mAHD), meters head of water (mH20).
Geomotion has also supplied and commissioned twelve water level data loggers. The system comprises a Sisgeo 4-20mA piezometer and Rippa 3G data logger installed within standpipe piezometers all housed beneath a trafficable GATIC. The water level is recorded hourly and uploaded on a 12 hourly basis, presented on Outpost’s online data management system. The system brings in data from nearby BOM stations to correct for barometric pressure changes and present rainfall data.
Geomotion have been commissioned to supply and install geotechnical instrumentation for the Waste Fines Storage Facility Project at Hope Downs 4 DSP Pit.
The Hope Downs 4 (HD4) mine is an iron ore mine located in the Pilbara region of Western Australia, 100 kilometres northwest of Newman. The mine is partly owned and operated by Rio Tinto Iron Ore (RTIO) and is one of twelve iron ore mines the company operates in the Pilbara.
UON’s client RTIO required an increase in capacity to the mining site's current waste fines facilities, necessary to continue plant operations. The works involved supply, install and construct the piping and waste fines facilities infrastructure including geotechnical monitoring equipment, relocation of existing infrastructure inclusive of the removal and replacement of HV and fibre optic cable, pumping equipment and an extension to the piping facilities inclusive of trenching earthworks.
The geotechnical monitoring system used the proven Vibrating Wire (VW) Technology on Piezometers and Pressure Cells running below ground conduit excavation along the pit bench attached to Load Sensing VW Node Dataloggers inside two Terminal Boxes located at the pit surface for remote monitoring.
The VW Piezometers were installed in 20L buckets filled with saturated waste fines slurry to measure and monitor pore water pressures. The VW Pressure Cells were installed on 500x200mm blinding concrete plinths, backfilled with waste fines, to determine the distribution, magnitude and directions of total soil pressure. The design will be used to monitor and control placement of ﬁll and essentially provide adequate warning of excess soil pressures into the operational life of the pit structure.
Geomotion are excited to announce the launch of GLS Monitoring; a collaboration between Geomotion and Land Surveys to provide a complete monitoring solution for major projects.
GLS Monitoring offer the respective expertise and experience from the two companies, offered as a single port of call for project wide monitoring including precision survey, state of the art instrumentation, cutting edge telemetry and comprehensive reporting.

Geomotion recently completed the establishment of a complete remote monitoring solution for South32 at its Worsley Alumina refinery near Collie. The system draws on data from piezometers spread over 5km across the site.
Manual monitoring of piezometers across the site was a lengthy process usurping a significant amount of man hours to ensure the safety of the plant infrastructure. With the new system implemented by Geomotion Australia, data is updated daily on a web based data management platform, with the ability to increase read frequency during critical periods. It allows up to date monitoring, comparison to weather events or pumping activity on site, and offers a comprehensive yet accessible review and report functions.
The Loadsensing G6 data logging system allows up to 10 years power autonomy, yet maximum coverage across the site. With a single Gateway positioned at the site communications tower, the site is covered for monitoring of tailings dams across the facility. Maxwell Geosystem’s Mission Monitor powers the data management and reporting functions.
The project follows the successful implementation of over thirty G6 data loggers across the Illawarra Region with Geosensing Solutions on behalf of South32.

Project: New Perth Stadium Station
Site: Burswood, Perth
Client: Prism Alliance ( Laing O’Rourke, Aecom, Perth Transport Authority)
In 2018, the multi-purpose 60,000 seat new Perth Stadium will open for the kick-off of the AFL season.
To ensure the safe and efficient movement of the crowd within an hour of an event finishing, the new six-platform Stadium Station will be one of the new infrastructure as a part of the transport strategy. Indeed, 28,000 people are expected to leave from the new Perth Stadium Station.
Geomotion has recently completed the installation of eight Vibrating Wire Piezometers, six 4-20mA pressure transducers, seven MEMS tiltmeters, three Settlement Plates and two inclinometers as part of the Perth Stadium Station Project which will be finalised in advance of the 2018 AFL season.
The equipment is used to monitor the pore water pressure, the piezometric head of ground water during dewatering, the tilt of the Victoria Park Bridge and the settlement of surcharge.
Considering the scale of the project and the distances between the sensors installed, it made sense to use the LS-G6 long range wireless telemetry system by its cost effectiveness and long range performance. The gateway receives the data from all the sensors installed onsite with a distance of 3.5 Kilometers form the furthest monitoring point then relays data to our web-based data presentation package, ARGUS.
Using this system, the client can receive the data in real time and be warned via SMS / Email if any instrument exceeds the set alarm thresholds.
Project: Swan River Pedestrian Bridge
Site: Burswood & East Perth
Client: Rizzani York Joint Venture (Rizzani de Eccher / York Civil)
The Swan River Pedestrian Bridge forms part of the new Perth Stadium’s integrated transport strategy designed to move patrons safely and efficiently to and from the Stadium and Sports Precinct.
More than 14,000 people are expected to use the Bridge on event days to move between East Perth's Nelson Avenue and the Burswood Peninsula, adjacent to the Stadium.
Spanning 370 meters across the Swan River the Bridge will be available for community use at all times, showcasing the beauty of the river, adjacent parklands and the Stadium Precinct.
Bridge construction works are underway with the construction of two temporary causeways in the Swan River commencing in January 2016. Bridge foundations are expected to be completed by mid-2016 with the Bridge opening in early 2017.
The following indicative monitoring installations have been installed by Geomotion to assess the settlement/movement of the causeways during the construction period:
