About IGS

The Business

IGS is a specialist in situ testing and sampling contractor, recognised both nationally and internationally as 'one of the best.' We are physically based and staffed in Brisbane, Melbourne & Perth. We also operate 'virtual bases' in Sydney, Newcastle, Launceston, Townsville and PNG. IGS is 100% Australian owned, run and staffed.  

The company started in Brisbane in 2000 under the vision of its founder, Allan McConnell (an experienced geotechnical engineer), to introduce up-to-date in situ testing & direct-push sampling technology to the Australian market, with the clearly-expressed mission of helping clients to 'reduce geotechnical uncertainty.'

Including our founder Allan McConnell, who these days is focused on mentoring and training, in a transitioning phase, IGS is managed by three very experienced geotechnical engineers and two long-experienced Project Operators. No-one can claim to better understand our clients in situ testing and sampling needs and to know how to satisfy these.
