      Experience Working Near Railways

      Our experience adjacent to operational railways
      CGL has worked on major rail projects and associated infrastructure for well over a decade.  As a pragmatically oriented
      consultant, CGL brings experience of complex ground movement studies, interpretation of ground models, plus value
      engineering of foundations and support for existing infrastructure and structures, to facilitate construction and maintain
      serviceability in such projects.  Through its work in the energy sector, CGL has considerable experience of extensive linear
      cross-country ground investigations, plus the challenges that they present for access. CGL brings this experience with
      knowledge of the buildability of tracks for plant to remote sites to meet such challenges.

      Through an associated and experienced specialist consultant CGL can also provide advice on the rail asset interfaces for
      CEM/CRE when required, providing input at all stages of the GRIP process.

      Some of the more relevant projects which CGL have completed in the rail sector are summarised below.
