 Mascot Towers, Sydney 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.

January’s fatal tailings dam collapse at Vale SA’s Corrego do Feijao mine has sent the global mining industry once again scrambling to check the integrity of its tailings management systems. The January 26 tailings dam collapse at the Corrego do Feijao mine near the town of Brumadinho, in Minas Gerais, killed more than 300 people and came just four years after the Samarco tailings collapse in the same state became Brazil’s worst environmental disaster and also killed 19 people. Brazi’s mining regulator ordered Vale to suspend operations at its Fabrica and Vargem Grande complexes immediately after the Brumadinho disaster. In a statement, Vale said the mining regulator ordered the suspension in light of the possible failure of five dams at the mining sites in the interior state of Minas Gerais. Since then, both authorities and mining companies have stepped up scrutiny of so-called upstream dams, which have been subject to multiple high-profile failures in recent years. In a statement, Vale said it was abiding by the regulator’s decision but was asking the body for permission to dismantle the dams, while continuing some operations at the mine, “which would bring about limited impacts on production”. The miner did not offer an estimate on how much production likely would be lost. However, the company had previously planned to maintain operations at Fabrica via dry mining, which eliminates the need for upstream dams. The company estimated that plan would result in 3mt of lost production in 2019. “The cost of the wireless monitoring makes more sense than a couple of employees driving around different locations, taking measurements every few months. It eliminates errors, increases safety in remote locations and reduces costs because it is less labour-intensive,” - Kim Malcolm, Geomotion Minas Gerais is still recovering from the 2015 Samarco collapse which buried a village and poured toxic waste into a major river. Vale chief executive Fabio Schvartsman said the dam that burst was being decommissioned and its capacity was about a fifth of the total waste spilled at Samarco. Schvartsman said there had not been any recent construction around the dam and apologised without taking responsibility in a television interview. “Apologies to society, apologies to you, apologies to the whole world for what has happened,” he said. “I don’t know who is responsible, but you can be sure we’ll do our part.” The disaster prompted the world’s largest miners to announce risk reviews of their tailings facilities. BHP Ltd, which was Vale’s JV partner in Samarco, said it had “significantly increased the rigour of its assessment and management” of tailings since 2015, including a risk review which resulted in more than 400 actions being assigned to company assets. “These actions are 93% complete, with the remaining actions considered low priority such as administrative actions and long-lead items regarding closure and climate change impacts. None of these actions is overdue,” the company said in a statement on February 19. Rio Tinto Ltd – which has 100 active tailing facilities and a further 36 closed or under rehabilitation – said its tailings facilities were subject to three levels of governance and assurance. “In August 2015, Rio Tinto introduced a standard for management of tailings and water storage facilities in order to ensure all our managed facilities are operated in accordance with one global standard,” chief executive J-S Jacques said. “In light of this tragic event, Rio Tinto is again reviewing its global standard and, in particular, assessing how we can further strengthen the existing audit of facilities.” Perhaps the most surprising aspect of the disaster is how late Vale was in recognising the dangers. Schvartsman said equipment had shown the dam was stable on January 10 and it was too soon to say why it collapsed. However, according to Geomotion Australia managing director Kim Malcolm, modern instrumentation and software allow for real-time monitoring of tailings facilities. “In the past it was prohibitive to have real-time monitoring because of all the cabling required but now wireless data loggers are readily available; there was never previously anything available that could do that,” he said. Geomotion works with a number of major miners in Australia including Rio Tinto, South32 Ltd and Newmont Australia providing geotechnical and structural instrumentation and asset monitoring. Malcolm said the days of having just a few sensors on a tailings dam, intermittently monitored by hand were rapidly ending. “The cost of the wireless monitoring makes more sense than a couple of employees driving around different locations, taking measurements every few months. It eliminates errors, increases safety in remote locations and reduces costs because it is less labour-intensive,” he said. Software such as the Mission Monitoring operating system also allows companies to anticipate problems as well as alerting them to impending spills. “It is less about the alarms but about the constant, real-time review,” Malcolm said. “It allows you to see the trends well before anything happens.” The web-based software could also present opportunities for companies to better relate their tailings management to affected communities. “The software is designed so alarms are set up on individual smart phones,” Malcolm said. “It allows companies to select who has access to the alarms and they can even present the monitoring data on open websites to ensure their management has a more public-facing interface.” – Dominic Piper - Australia's Paydirt (March 2019)  In line with the current VIBRA-series, of which thousands are now in use worldwide, Geomotion partner, Profound BV, proudly introduce the new VIBRA+.

 The final piece of Sydney's WestConnex puzzle has been placed, after the New South Wales Government today announced stage three of the controversial project had been approved. Key points:
It means a tunnel will be built connecting the M4 at Haberfield to the M5 at St Peters — a development WestConnex Minister Stuart Ayres described as being "like the Sydney Harbour Bridge". It will create a non-stop bypass of Sydney's CBD and inner-west, slashing travel times. However, the proposal has also attracted significant opposition. This time last year, Sydney Lord Mayor Clover Moore briefed Premier Gladys Berejiklian on a set of alternatives at a meeting. The $17 billion WestConnex development has been previously described by the NSW Government as the world's biggest road project. Stage three will also include links to the Iron Cove Bridge and Rozelle Interchange. Mr Ayres said the tunnel was crucial to the city's transport future. "Like the Sydney Harbour Bridge did for the North Shore, the M4-M5 Link will bridge a major gap in the road network, creating a non-stop underground western bypass of Sydney's CBD, slashing travel times and delivering over 18 hectares of open space for local communities," he said. In August 2017, the Environmental Impact Statement (EIS) for WestConnex stage three said the project would slash travel times from Sydney's western suburbs to the CBD. It argued the 55-kilometre trip from Penrith to the CBD could cost drivers $22 today, but when WestConnex was finished, the tolls would be capped at $8.60 for the same journey.  Final stage 'hasn't even been designed', Labor says Labor's roads spokeswoman Jodi McKay accused the Government of trying to avoid public scrutiny by announcing the approval on a Friday afternoon. "This is the largest infrastructure project in the states history, the final stage of it, and no one is around to actually enlighten people about this project," she said. Ms McKay said the Government rushed the approval process for the Rozelle interchange and ignored community concerns because it is seeking to sell the Sydney Motorway Corporation. "This is an extraordinary situation given the Government has approved something that hasn't even been designed," she said. "There has been no community consolation, there has been no transparency yet suddenly today we find out it's been approved." Project settled behind closed doors: Greens Reacting to the approval of West Connex's final stage, Inner West Mayor Darcy Byrne said: "What we've just discovered is that West Connex stage three was secretly approved 10 days ago behind closed doors". "No wonder the Government is ashamed of this wasteful project," Mr Byrne said. "Throughout the Inner West we're now going to see more smoke stacks and the mother of all rat runs. "With the demolition of homes, the secrecy behind the West Connex project, people know this Government has it in for us and...[stage three] will be worse than anything we've seen yet." Mr Byrne said he wanted "to see the Government invest in a proper solution to modern congestion which is of course...public transport." 'We need to see transparency' State Greens MP and member for Newtown, Jenny Leong, said "the arrogance of the Berejiklian Government knows no bounds". "We have seen tens of thousands of submissions from the community and experts opposing this (project). "The public appetite is there... to open up the books. "The community have put their concerns front and centre in this planning process." Ms Leong said the NSW Greens were pushing for more transparency. "We are urging the NSW Labor Opposition and the crossbenchers of the upper house to support the Greens' call for the exposure of the papers. We need to see transparency and accountability." SOURCE: ABC News 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:
 A NSW goldmine forced to shut down for three months last year after an earthquake has again halted operations following a dam wall breach.
The wall of a tailings dam at the Cadia mine, about 20km south of Orange, partially collapsed on Friday after there were two magnitude 2.7 earthquakes in the region on Thursday. Its operator Newcrest Mining says there is no threat to personal safety and it has secured the area around the dam. A "comprehensive geotechnical monitoring system" was implemented, the company said on Saturday. The material involved, which was contained within the southern dam, was described as "a slurry of finely ground rock, water and a low level of benign processing re-agents". The mine was forced to shut down after it was hit by a magnitude 4.3 earthquake in April 2017 and didn't return to partial production until July, causing a huge hit to the company's first-half profit. Source: The West Australian (AAP)  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. |
