For surveyors and equipment operators, the earthwork undertaking was a potentially chaotic data management challenge that could have resulted in potentially missed, misplaced or inaccurate data and delays for approvals over the course of earthwork activities. At any given moment, for example, there might be over 270 pieces of earthmoving equipment in action on the job.
For the joint venture contracting team, these specs posed a considerable challenge. In the past, the project team would have used conventional methods for tracking and sharing material movement, namely spreadsheets and USB sticks. That methodology simply wasn’t going to work on a project of this size and with the need to share multiple design changes a day to ensure proper layer thickness and optimal material placement.
So the joint venture team, working with SITECH Solutions Pty Ltd and Trimble, developed a cloud-based survey, compaction, testing and conformance workflow.
The biggest advantage of the field-to-office-to-field workflow, according to the joint venture team, was that it allowed the foreman and machine operators to know where they could place fill and where they couldn’t, without physical stakes and survey marks, which enabled them to build the site with minimal traditional survey methods. There’s not one peg on the site—thereby improving productivity and safety.
“Without this digital workflow, the entire process would have been very laborious, and we would have lost the ability to keep surveyors off the site. We would have had to take a much more hands-on approach. Every material layout is accountable, so the quality of the job was the biggest improvement, as was our ability to maintain high production.” - Brett Hussey, project survey manager at ACCIONA.
