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”.

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.” Source: www.forrestfieldairportlink.wa.gov.au 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.   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. |
