How good are ground gas protection measures on buildings?

Dr. Geoffrey Card will be Chairing and Speaking at the CIRIA conference event “How good are ground gas protection measures on buildings?” tomorrow in London.  The average life of a commercial building is 30 years and a residential building is about 100 years.  Many do not have adequate (or rather old) gas protective measures in place.  Even if they have, as increasing rainfall and severe weather events become more frequent due to climate change, the existing gas mitigation can be adversely affected.

Dr. Geoffrey Card will:

  • Review guidance for existing development;
  • explain the problems with retrofitting gas measures for developments (residential, commercial and industrial) for both above ground (for people living and working in the buildings) and below ground situations (e.g. in basement);
  • explain the pros and cons of the available mitigation options and provide examples on how these can be done successfully

Geological faulting under Wimbledon Stadium

Galliard Homes is currently developing the former Wimbledon Greyhound Stadium, with the car park being redeveloped for high-rise residential usage and the stadium also being demolished and re-built to create the new home for AFC Wimbledon.   GB Card & Partners has recently managed the ground investigation and provided planning and design support for the 6-hectare brownfield redevelopment.

Landfills & Part 2A Liability

The liabilities associated with purchasing a potentially contaminated site are far from straightforward and the Court of Appeal judgement in the case of Powys County Council v Mr. Price and Mrs. Hardwicke highlights this better than any.  The recent refusal of permission to appeal by the Supreme Court cements the original Court of Appeal ruling.  Those who own potentially contaminated sites (such as former landfills) and their advisors need to be aware of the ramifications that this judgement has regarding contingent liabilities (i.e. a liability that may occur subject to the outcome of a future event).
