GBG was originally a consulting company established in the UK in 1982, specialising in the application of geophysical techniques for geotechnical, environmental application and engineered structures across Europe.

In the following years, it has expanded as a multinational enterprise basing themselves in Australia as GBG Australia and GBGMAPS, and in the USA as GBGUS. Together the offices provide services stretching from the single pre-stressing strand in a concrete slab to a mine-scale exploration geophysical investigation.


GBG Australia originally began as a joint venture with CMPS&F and GHD before becoming a standalone company in 2003.

Over the next 15 years, GBG Australia grew to became the largest geophysical consultancy on the East Coast of Australia.

They have employed engineers and geophysicists of extensive experience, and have provided advanced tailored investigation solutions for geotechnical and environmental investigations and non-destructive investigations of structures for a wide variety of clients from all industries.


GBGMAPS, formed in 2008, is a joint venture between GBG Australia and MNG (formerly McMullen Nolan Group/McMullen Nolan and Partners).

The joint venture recognises the need for alternative surveying services in relation to the environmental geophysical services of GBGMAPS.

In the last eight years, GBGMAPS has established themselves in Perth to collaborate with MNG’s industry-leading survey and spatial information services with their geophysical expertise in and beyond Western Australia.
