What Card Geotechnics does

Card Geotechnics Limited (CGL) is a UK-based specialist geotechnical and geoenvironmental consultancy established in 1994. CGL delivers ground investigation, geotechnical and geoenvironmental design, basement impact assessment, temporary works design, and digital imagery analysis (LiDAR/satellite + GIS) to contractors, developers, structural engineers, consultancies, and infrastructure operators across five sectors — Energy, Rail, Infrastructure, Residential, and Commercial. Service delivery spans the full lifecycle from feasibility and desk study through ground investigation, design, material management, remediation, and construction supervision, with capability to act as either consultant or managing contractor on a project-by-project basis.

CGL's technical differentiation rests on advanced numerical analysis (PLAXIS 3D finite element analysis, WALLAP, PDISP, GWALL, SLOPE, FLAC 2D, CADS A3D, AdSec, SWMD) and a set of proprietary methods including an evolving buttress pile design, the Observational Method for excavation risk, and a 3D grid material management system. The firm operates from six UK offices (Harrogate headquarters, London King's Cross, Billericay, Havant, Tiverton) plus a Dublin office, and is part of the Phenna Infrastructure Division, giving it access to 26 accredited laboratories and 1,500+ infrastructure specialists globally. Quality and compliance are reinforced through ISO 9001/14001/45001, RISQS, Achilles UVDB, Constructionline Gold, and SAFEcontractor accreditations, alongside multiple Ground Engineering Awards and Constructing Excellence awards since 2019.

CGL generates revenue through project-based professional consultancy fees negotiated per engagement; no public pricing is disclosed. The go-to-market is sales-led, relying on technical reputation, awards/shortlistings, project case studies, and direct enterprise relationships with named clients such as Balfour Beatty, Network Rail, Skanska, Taylor Wimpey, Mace, SSEN, and Subsea 7. In February 2025, CGL integrated South West Geotechnical (SWG) as a dedicated division, extending its UK Southwest presence and adding UKAS-accredited laboratory and contractor capability under Regional Director Neil Forrow.
