GGC is headed by a dedicated team of people who bring together a wealth of knowledge and experience to cover every aspect of geotechnical engineering and enable us to deliver unparalleled quality and service.

Everything we do at GGC is guided by our values – they shape our company culture, our interactions with people and our approach to every project.



We’re open, honest and consistent in our principles and conduct, so we’re able to build trusted relationships with our clients and partners.


We always assume responsibility for our actions and make decisions in line with our economic, social and ethical obligations.


We treat everyone with respect and dignity and develop relationships founded on understanding and trust.


We pursue excellence in everything we do, challenging ourselves to look beyond the obvious and ensure ongoing improvement.

Our approach is the sum of our values, people and unwavering commitment to deliver the best outcomes for our clients.

Close collaboration is the backbone of every project we undertake. Our directors and staff work as a team together with external architects, planners and other consultants appointed by the client. Throughout the entire project, we maintain open lines of communication and foster positive relationships with everyone involved.

Occupational Health and Safety is a responsibility we take very seriously at each level. We’re committed to providing a safe and healthy working environment for all of our staff, clients and contractors, and reinforce our safety message at all relevant GGC meetings. To ensure our procedures are constantly updated and improved, we have an Occupational Health and Management System accredited to AS/NZ 4801.

We embrace innovation and engage industry-leading technology and practices to ensure that our engineering solutions are of the highest standard. We follow strict quality control measures and have attained ISO 9001:2008.

We value the sustainability of the natural and social environments, and operate with an ISO 14001 accredited Environmental Management System (EMS).

The quality of our work is matched by the high level of service we provide. We aim to anticipate our clients’ needs and develop appropriate and timely engineering solutions that exceed their expectations. We offer consistent, personalised service and handle every project with the utmost attention and importance.

We have a proven track record of employing and retaining talented, experienced professionals, and enjoy a low staff turnover. For our clients, this means always dealing with people who are deeply involved in and knowledgeable about their project. We employ engineers, geologists and support staff who share our company values and make meaningful contributions to the work we do.

We stay abreast of issues and developments in the geotechnical community and contribute to its future through active involvement in several industry bodies.
