CIRIA C735 Report, Highly Commended

The recently published guidance document CIRIA C735 – Good practice on the testing and verification of protection systems for buildings against hazardous ground gases won a ‘Highly Commended’ accolade at the recent Brownfield Briefing awards in the Best Scientific (or Verification) Advancement category. Against a strong field of over 70 projects, the guidance was one of only 4 to receive the award.

The report, which was jointly authored by EPG Ltd, Burro Happold, MEC Environmental and Arup is the first guidance on the installation of gas protection systems for buildings was published in the early 1990s. Since then the frequency of installation and variety of systems has increased considerably. However, there is evidence that the installation of many of these systems has failed to meet an acceptable standard.

This publication provides good practice guidance for the designer, installer, verifier and regulator on the verification and integrity testing of gas protection systems. It sets out a flexible, risk based and practicable framework that can be adapted to provide sitespecific advice on the need for and scope of verification activities (including any integrity testing).

Recommendations are presented for the promotion of the good practice described in this publication and for recognition of the important role that local authority (LA) regulators play in its increased acceptance and application throughout the industry.
