Risk assessment for ground gases

10 September 2008, Birmingham

The problem

With the government pushing for more redevelopment on Brownfield sites, many house builders
have been forced to build in close proximity to landfill sites or other sites where underground gases, are a potential threat. There is often a great deal of uncertainty regarding the extent of ground gas investigations required, the form that risk assessments should take and the choice of the most appropriate protection methods for developments.

A solution

This workshop will describe current best practice in the investigation and assessment of ground gases. It will enable construction professionals to make rational and informed decisions regarding developments on gassing sites.

Who should attend

local authority contaminated land officers, planners, environmental health officers
consulting engineers and environmental consultants
contractors
developers
landowners
house builders
other regulators
researchers and academics
