PYBAR has been contracted by John Holland to supply a Jacon Maxijet robotic shotcrete rig with experienced operator/nozzleman for the Hume Highway underpass of Sydney’s Glenfield to Leppington Rail Line project.
PYBAR’s Shotcrete manager, Adam Crouch, comments, “We are looking forward to the chance to diversify outside our mining work, it’s not every day you get to help a large construction company like John Holland tunnel beneath an eight-lane highway.”
Patrick Dunne and Jeff Gayagay are working on the project for PYBAR. Patrick has worked on Brisbane’s Clem 7 tunnel and Airport Link where he sprayed temporary and permanent shotcrete to a very high standard, including areas with difficult geometries such as transition zones in the tunnel profile, substations and pump stations. Jeff joins this project from the shotcrete crew at CSA Mine at Cobar and is looking forward to being reunited with his family in Sydney.
The machinery being used on this job is the Jacon Maxijet rig. It has robotic boom technology, with 12 different functions in one remote control allowing the nozzleman to maintain a safe working distance from unsupported ground during shotcrete application.
