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.

The project includes a staged warning system during Maritime works as part of the construction management plan, as well as monitoring of key structures including the Riverside Expressway.
The Forrestfield-Airport Link (FAL) project will deliver an 8.5 km extension of the existing PTA urban rail network in Perth, Western Australia connecting the Midland Line, just past Bayswater Station, to Forrestfield, running underground in twin bored tunnels underneath the Swan River, Tonkin Highway and Perth Airport. The project will include three new stations, being: Redcliffe Station (located underground in Redcliffe), Airport Central Station (located underground at Perth Airport to service both domestic and international terminals) and Forrestfield Station.
The project will provide new rail services allowing a 20-minute rail journey from Forrestfield Station to the Perth CBD, improved bus networks for the eastern suburbs, foothills and surrounding communities as well as integration with the full Transperth bus and train network.
Redcliffe Station and Forrestfield Station will have rail-bus interchanges and up to 2,500 new car parking bays in total.
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.
