Question to the Ministry of Justice:

To ask His Majesty's Government whether they have any plans to audit all prison buildings constructed between 1950 to 1990 for the presence of reinforced autoclaved aerated concrete; and, if so, what is their timescale.

Departments have been asked to report on the current picture of suspected and confirmed Reinforced Autoclaved Aerated Concrete (RAAC) in their estates as soon as possible. This will be updated on a regular basis as new buildings are identified and surveying and remediation are carried out. The Government published lists of education settings confirmed as having RAAC on Wednesday 6 September and committed to providing further updates.

The potential mitigating actions for prison buildings will be to monitor them, prop them up or replace them, in line with Institute of Structural Engineers guidance.
