Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many and what proportion of (a) barracks, (b) service family accommodation and (c) training facilities are affected by the presence of reinforced autoclaved aerated concrete; and if he will make an assessment of the potential impact of reinforced autoclaved aerated concrete on the structural integrity of those buildings.

Surveys are currently being conducted to identify buildings which may have been constructed with Reinforced Autoclaved Aerated Concrete (RAAC). Following this, specialist suppliers will confirm presence of RAAC. If identified, a risk assessment will be conducted and discussed with the appropriate site teams to ensure appropriate mitigation is applied and monitored. Where RAAC is suspected, but not confirmed, a risk assessment and mitigation will be put in place anyway.

Until surveys are complete, it is not possible to provide a breakdown of barracks, service family accommodation and training facilities which might have been constructed with RAAC.
