Established in 2015 by three forward-thinking engineers, Civil Geotechnical Consultants (CGC) emerged with a shared vision: to pioneer a company that not only tackled geotechnical challenges with ingenuity but also left an enduring positive mark on the community. At the core of CGC's mission is a resolute commitment to forging robust partnerships, devising innovative solutions for clients, and building strong foundations in both engineering and the lives of vulnerable young people within our community.


In 2019, CGC achieved a significant milestone by attaining certification as a social enterprise from Social Traders - the first engineering company in Australia to do so. This formal recognition underscores our unwavering commitment to positive social change. We invest half of our profit into initiatives specifically designed to improve opportunities for young people.

CGC provides specialised engineering services for critical transport, energy and civil infrastructure projects across Australia. Our involvement in these projects is a testament to our proven expertise, backed by extensive experience, deep knowledge, and the highest geotechnical accreditations.


With strategically located offices along the Eastern Seaboard, CGC is well-positioned to deliver smart, practical, and cost-effective engineering solutions. Our geotechnical engineering expertise span all project phases across design and analysis, site investigations, construction services, advisory, value engineering and aerial mapping.


Through our geotechnical expertise and unwavering dedication to social impact, CGC creates stronger foundations through engineering solutions and commitment to community.
