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.

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.
The $1.86 billion Forrestfield-Airport Link is jointly funded by the Australian and Western Australian governments and will deliver a new rail service to the eastern suburbs of Perth – with three new stations at Belmont, Airport Central and Forrestfield.
The rail link will connect with the existing Midland line near Bayswater Station and will run to Forrestfield through underground tunnels, to ensure minimal impact on the existing land and road network.
This landmark transport project will:
• Increase public transport options for the eastern suburbs and foothills area.
• Improve access between the city and Perth Airport.
• Drive development in the area to benefit current and future residents.
Early in 2016, the major contract for the Forrestfield-Airport Link project was awarded to Salini Impregilo - NRW Joint Venture (SI-NRW). This contract will see SI-NRW design and build 8km of rail tunnels and three new train stations, and maintain the infrastructure of some items for a 10-year period, once the project is complete in 2020.”
The FGLS Joint Venture (Field Monitoring Services Australia – Geomotion Australia – Land Surveys) is providing a complete monitoring solution to the lead contractors SI-NRW JV.
SISGEO Group supply and supervise to the installation of all the geotechnical and structural instrumentation, including data loggers (OMNIAlog and miniOMNIAlog) to FGLS JV.
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.
Worldsensing LS-G6 long range radio data loggers are changing the way Australians are monitoring their projects. Now implemented on major projects in every state in Australia, the system is proving its reliability and ease of use.
Geomotion Australia are utilising the system to monitor train stations in Perth; highway developments in Ballina and Adelaide; dams in the Northern Territory, Western Australia and Tasmania, as well as processing plants in Western Australia and schools and high-rise apartment buildings in Melbourne.
Through simplicity, low-to-no maintenance requirements and low cost, the LS-G6 system is bringing automation and remote data access to sites where previously the cost and practicalities would have been prohibitive.
The LS-G6 models are capable of reading Vibrating Wire (VW), analogue and digital sensors. This means that on a single site we are monitoring groundwater, cracks, structural health and pile deformation with the same data system, each with a low-profile autonomous data logger recording and transmitting the data.
