Connected to Wider Infrastructure Expertise

CGL is part of Phenna Group’s Infrastructure Division, a network of specialist businesses delivering technical expertise across every stage of infrastructure and development projects. Together, the division supports clients from early planning and ground investigation through to design, construction, testing, monitoring and the long-term management of assets.

As part of this collaborative network, CGL continues to deliver the geotechnical and geoenvironmental expertise, practical engineering solutions and responsive service our clients rely on. Where projects require additional capabilities, we can work alongside other businesses within the Infrastructure Division to provide access to complementary specialist services.

Beyond Infrastructure, Phenna Group also operates across the Built Environment, Industrials, Food & Life Sciences, and Certification & Compliance sectors. This wider capability gives CGL clients access to an extensive range of testing, inspection, certification and compliance expertise, while continuing to benefit from the personal service, technical knowledge and trusted relationships that define our business.
