The Geotechnical Consulting Group LLP (GCG) was founded in 1983 by Professor Lord Robert Mair, Professor David Hight and the late Professor Peter Vaughan to provide geotechnical consulting services employing state of the art research and developments in our understanding of soils and rock. GCG has established a reputation for developing innovative geotechnical solutions to technically demanding engineering problems, and is widely recognised as one of the world's leading independent geotechnical consultants. Our capabilities draw on the latest developments in engineering theory, research and practice from around the world.
We are an independent Limited Liability Partnership (LLP), providing expert advice to a wide range of clients including consultants, contractors, government departments and agencies, private and public companies, legal practices and research organisations.
GCG staff serve on professional and specialist committees and are closely involved in implementing new methods of design and analysis.
Our people are pioneers within the geotechnical community giving many prestigious named lectures (including Rankine (7Nos), Geotechnique (5Nos), Harding (2Nos), Terzaghi (1No) and Glossop (1No)) and chairing several professional bodies (e.g The British Geotechnical Association (BGA), Engineering Group of the Geological Survey (EGGS), and Construction Industry Research and Information Association (CIRIA)). Lord Mair, a founding partner, is a former President of the Institution of Civil Engineers (ICE). Eight members of the GCG team are Fellows of the Royal Academy of Engineering. Members of GCG have published hundreds of technical papers and major state-of-the-art reviews.
GCG are members of the Association of Geotechnical & Geoenvironmental Specialists (AGS) and core members of the Construction Industry Research and Information Association (CIRIA). Our Staff and Associates regularly participate in workshops, and are actively involved in developing industry best practice guidance for geotechnical issues.
GCG operates an effective and efficient quality, environmental and occupational health & safety management system. GCG’s management system has been assessed and approved, by a UKAS Accredited Certification Body, as meeting the requirements of BS EN ISO 9001:2015, BS EN ISO 14001:2015 and ISO 45001:2018.
GCG is registered on the SSIP (Safety Schemes In Procurement) Accredited Registered Scheme.
GCG maintains strong links with world class universities (notably with Imperial College, Cambridge, City, Oxford, Dundee, Barcelona, Kobe and Tokyo Universities and the National Technical University, Singapore) to enable early implementation of state-of-the-art research and development into engineering practice.
