COVID – CGL Working Arrangements

From the initial lockdown in late March CGL has continued to work within government and industry guidelines to maintain as near “normal” working as can be achieved.  Staff are in the main either working from home or they are on site working within either our own or overarching client requirements as appropriate.  Our offices are open to support colleagues but on a reduced attendance basis and of course we remain available for meetings and conference calls through the likes of Microsoft Teams or Zoom and traditional phone lines/mobiles.    

We are being careful to source suppliers who will work to our own, and client requirements, in what is proving to be a busy time for us all.  Sometimes that requires a little patience to achieve and we are grateful to clients in recognising these impacts as we organise our work for them.

We continue to provide the ground solutions are clients expect of us and wish to thank all our clients both old and new for working with us to deliver their needs in these unusual days.

Leadership in Ground Engineering

“We can help you to manage risks, forecast and contain costs, or turn marginally viable proposals into profitable opportunities.”

CGL is the UK’s biggest independent specialist geotechnical and geoenvironmental consultancy, delivering leading edge services for a wide range of clients. We provide advice and design solutions on a broad range of ground-related issues, working directly with site developers or their design and construction teams.

Our strengths are our core engineering knowledge and broad perspective incorporating both geotechnical and geoenvironmental expertise. Our deep understanding of ground and contaminant behaviour means we can give you cost effective advice on complex site conditions. We can provide value engineered solutions for difficult sites that often turn marginally viable developments into profitable opportunities.
