Hazardous Ground Gas - An essential guide for housebuilders

Are you up to date with current best practice to manage hazardous ground gas? Do you know how to identify a high-risk site and what action to take? Could you confidently identify a minimal risk site to avoid unnecessary gas protection?  

These are some of the issues experts tackle in this report, commissioned from the Environmental Protection Group and Buro Happold.  

The expert advice ranges from initial investigations and assessment of ground gas, to gas protective measures. It applies to all sites, small or large, straightforward or complex. Adoption of the good practice procedures described in the report will lead to better quality practice, cost savings and a greater understanding of specific issues around detailing, construction and verification.  

More specifically, the guidance will help you to:  

• recognise high risk sites and the appropriate action to take 

• avoid unnecessary gas protection on low/minimal risk sites 

• appoint appropriate competent professionals at the right stage 

• complete the process of assessment, design, implementation and verification 

• implement monitoring strategies suitable for the size, complexity and gas risk of the site. 

The report guidance also addresses the current gap between the conclusions and recommendations of ground investigation reports and the structural design of buildings where gas protection measures are not always included.
