James Sharpe, Survey Manager, CPB Contractors, purchased the TinySurveyor line marking robot for the West Gate Tunnel Project that involves an upgrade of the existing West Gate Freeway and a new tunnel.
“It’s quite a major upgrade of an existing freeway in the western suburbs of Melbourne. It involves a complete reconstruction of the freeway, it’s not just a widening, we’ll basically be rebuilding the whole freeway in stages” said Mr Sharpe.
“The TinySurveyor will be used for all the road projects moving forward. There’s always an intensive road line marking component on all our road projects.”
Consistency and Repeatability in Road Projects
Another CPB Contractors Project team was already using the TinySurveyor so Mr Sharpe was able to run a trial, quickly deciding that his team also needed a TinySurveyor after experiencing the increased safety for team members and the speed at which it could complete tasks onsite. One benefit that surprised Mr Sharpe was the consistent accuracy the TinySurveyor offers.
“The TinySurveyor gets our surveyors out of the firing line and just the speed it is able to work at is impressive,” said Mr Sharpe.
“The thing we didn’t really know prior to trialling the TinySurveyor was the consistent accuracy, the repeatability of the setout line. We found that the TinySurveyor matched in well with our surveying equipment. We checked the TinySurveyor constantly during the trial and the results obtained were always within GPS accuracy. It also important to note that if there is an issue with the position of the TinySurveyor, the unit doesn’t work at all. So far we haven’t had a instance where we set out a line onsite that’s been incorrect.”
TinySurveyor Increases Efficiency of Line Marking
Tasks currently being completed using the TinySurveyor previously required two surveyors. Now with the TinySurveyor, these two surveyors are freed up to do other tasks with the TinySurveyor being controlled exclusively by the Traffic Team Supervisor on night shift.
This also increases the efficiency of the overall workflow because the Traffic Team Supervisor is able to move on to the line marking portion of the work as soon as they are ready without having to locate the surveyor on site. Additionally, the surveyors do not have to be present on night shift and can focus their skill sets on other tasks.
“We understand they are the traffic team and they’re not surveyors, but this is the beauty of the TinySurveyor. I wouldn’t do it any other way now. We can get so much more traffic setout done onsite in a much shorter space of time,” said Mr Sharpe.
“We’re always rushed on night shifts, we’ve got a very, very small window but the TinySurveyor can do it at least four times quicker than a surveyor. We’ve also cut out a part of the traffic line marking process because now the line marking contractor doesn’t have to pre-mark the lane lines.”
“It’s pretty mundane work doing line marking, you’re always stopping bending over, you get lots of paint on your fingers and your boots, it’s not the most exciting surveying I’ve ever done,” added Mr Sharpe.
Mr Sharpe is also using the TinySurveyor for marking out micro-piles that need to be cored in a part of the project where the ground conditions need to be improved.
“We were going to use the robot’s point set out capability to go out and mark out thousands of micro-piles,” said Mr Sharpe.
“We thought that this was a really awesome way to individually set out all these thousands of micro-piles. We can just set the TinySurveyor up and send it out to mark out each micro-pile location in the grid and our guys just follow in behind to install a nail with flagging tied on it.”
