Most of the attendees had not been inside the Mt Coot-Tha Quarry that sits virtually next door to the Brisbane CBD and Brisbane River. The size and magnitude were surprising, however, the key takeaway for me was the latest role that it played with the 513m long conveyor tunnel that has imported all the tunnel spoil from the Cross River Rail Project to the quarry to eliminate approximately 110,000 truck movements off the Brisbane roads. The tunnel portal has reached the end of its design life and has since been closed up.
Last week UPG (Ultimate Positioning Group) and Trimble Inc. were invited to the Australian Tunnelling Society ‘s Mt Coot-Tha Quarry Industry Day to showcase the latest monitoring, scanning, GNSS and UAV technology in the sector of tunnelling (above and below ground) and asset management. The applications in this market segment are wide and varied and range from measuring the thickness of sprayed shotcrete to calculating stockpile quantities and monitoring of settlement with prisms or sensors. After several hands-on sessions with a mixed audience of major contractors, consulting engineers and Road and Rail authorities, we headed over to the Botanical Gardens for lunch.
The two comprehensive presentations provided by Brent Dawson and Kieran Dinuzzo after lunch, covered the deliverables in 3D models, available to all key stakeholders on a project, post processing, of the point cloud data collected at the quarry. This incorporated the combined use of UAV, scanning and GNSS Trimble hardware utilising Trimble Business Centre office software, Trimble Access for field data collection and Trimble Connect for communication and collaboration between the right people to the right constructible data, at the right time.
