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.

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 Australia are pleased to have completed their first installations on the Forrestfield-Airport Link. The installations of combined inclinometers / extensometers / piezometers as part of the Forrestfield Dive site mark the beginning of an extensive monitoring program set to continue for the next three years.
Geomotion Australia are part of the FGLS Joint Venture, bringing together Australia’s foremost surveying company, Land Surveys, and Italian monitoring specialists Field Monitoring Australia. The FGLS Joint Venture is providing a complete monitoring solution to the lead contractors SI-NRW JV, a joint venture between Salini Impregilio and Perth’s own NRW Civil & Mining. Geomotion Australia are responsible for the installation and monitoring of all geotechnical and structural instrumentation for the project. Instruments and data loggers will be supplied by Italian manufacturers SISGEO. As well as installation and monitoring, Geomotion are implementing and managing the MIMS (Monitoring Information Management System), Maxwell Geosystem’s Mission OS.
The Forrestfield-Airport Link project will provide a rail link between Bayswater and Forrestfield, including the construction of three new train stations, Belmont, Airport Central and Forrestfield. The twin tunnels travel beneath critical pieces of infrastructure; including airport runways and existing rail networks. To ensure the highest quality of construction and safety, SI-NRW has put in place the most extensive monitoring program in WA history, and Geomotion Australia is proud to be involved.
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.
