Industry leadership

CGL’s people are specialists in their chosen areas and are drawn from engineering, geological and environmental backgrounds. They provide a holistic approach to construction problems that delivers the cost-effective solutions for which we are known. 62% of our technical staff have Masters or PhD degrees and 40% are chartered professionals. This high level of qualification underpins our work, our capabilities and the convictions of our recommendations to clients.

CGL’s senior staff are heavily involved in delivering technical excellence to our clients. Our engineers are actively involved in developing the industry and are authors of technical papers on geotechnical and geoenvironmental engineering. They are also often invited to speak at conferences and are continuously updating their skills.

CGL started up in 1994 as Card Geotechnics Limited but that was only half the story as a lot of our work was in the emerging geoenvironmental market.  In 2011 we rebranded to CGL and in 2020 CGL was acquired by Construction Testing Solutions, a leading provider of testing, calibration and consultancy services with an ethos and values aligned to CGL. The shared technical capabilities and regional reach bring added benefits to our Clients as CGL continues to develop its service offerings and provide innovative value-engineered solutions for our many clients.
