Gladstone group well-grounded in technology

Gladstone group well-grounded in technology VAC Group and Earth Radar’s Mike Meade, Dave Ross, Lee Henderson and Tony Simpson.

Gladstone-based VAC Group has developed a new Ground Penetrating Radar (GPR) device to detect underground services and disturbances.

“Knowing exactly where various utilities lie beneath the surface is vital to ensure construction or maintenance can be undertaken safely and productively without unnecessary delays,” operations supervisor Lee Henderson said.

“With that in mind VAC Group and subsidiary Earth Radar have invested in the very latest GPR and developed their own armoury of technologies including satellite location and integrated surface line scan cameras.

“It’s the only product in Australia that can integrate surface with subsurface data and enable 3D visualisation of underground assets. The Computer Aided Radar Tomography (CART) enables us to detect other metal pipes, non-metal pipes and other unknown utility assets that would not be found using other industry standard technologies like electromagnetic induction.”

Mr Henderson said the new technology allowed the VAC Group to reduce the uncertainty associated with the reliance on old, incomplete, missing, ambiguous or unavailable utility data, by locating underground services to a high degree of accuracy.

“The older version of the technology only allowed a single channel but with the new equipment developed by Earth Radar it records 16 channels at once,” he said.

“That allows us to do a wider scan at more frequent intervals in the direction of travel to give us a 3D grid image of the subsurface.”

The GPR scanned the subsurface in conjunction with capturing surface imaging, he said.

“We then use GPS to pinpoint location and track where it has been as well as the capabilities to download all the information to create a Computer Aided Drawing (CAD).”

Gladstone Engineering Alliance chief executive officer Carli Homann said VAC Group’s innovation and expertise was just
another example of how Gladstone companies could deliver quality design and management.

“This is another great example of how a highly skilled supply chain can be sourced in Gladstone not only with expertise we can provide here in Gladstone but globally as well and the VAC Group have proven, like many companies, that they can play on a world stage,” Ms Homann said.
