CIOB statement on Reinforced Autoclaved Aerated Concrete
In response to the issues surrounding Reinforced Autoclaved Aerated Concrete (RAAC), which emerged in August this year, Eddie Tuttle, Director of Policy, Research and External Affairs at the Chartered Institute of Building (CIOB), said: “The CIOB has agreed to respond to the RAAC Crisis in collaboration with other industry bodies and we support the recent statement from the Construction Industry Council (CIC) and Construction Leadership Council (CLC) on the need for alignment across the construction industry.
“CIOB has joined a panel of technical experts to fully understand the impact of RAAC, to support the Government in its response, and to develop appropriate guidance that can be issued to the wider construction industry as well as impacted building owners.
“We also recognise that the emergence of RAAC showcases the pressing need for the creation and maintenance of the golden thread of information related to fire and structural safety of buildings.
“While this process is ongoing, anyone concerned by the potential impact of RAAC on their buildings should visit this website.”
