“Looking more closely at some of the key elements to efficient delivery, we can see how GPS technology and solutions like grade control on both dozers and more recently excavators, will play an important role. For example, data from the BIM model will be able to be processed and sent to numerous machines across the project. These machines will then be able to use GPS technology to make sure they dig and doze to the right depth or height respectively.
“This data in turn will then be sent back to a central hub and, if required, to a hand held device operated by the site manager, confirming the job has been done correctly. Similarly, when you are looking at productivity, once a job is done and registered, the equipment can be reassigned to other jobs.
“It is this effective management of equipment flow around a site that can really make a difference. In mining, when trucks are idling for an extended period
outside of a preset parameter, a site manager can get an alert and take action to solve a potential problem, or reassign the unit to other operations.
“When you are dealing with a much larger fleet of ADT’s, in the case of the HS2 project, having this focus on idling and work flow management can make a huge difference to fuel consumption and productivity. This is where site and workflow modelling comes into play. Site modelling is like extending the BIM model to incorporate items like haul roads, tips and the layout of the site itself. This is also a moving model that needs to incorporate changing site conditions through onsite surveys and trending data on machine productivity.
“With a large amount of plant expected to be hired it is the collaboration between all stakeholders that will be crucial and when it comes to plant performance the highly trained operator will be HS2’s most prized asset.”
