For now, the focus is on bringing together the information we hold about the Government estate into one place. This work is being coordinated by the Office for Government Property.

Surveys are currently being conducted to identify buildings which may have been constructed with RAAC on Ministry of Defence (MOD) land.

The Defence Infrastructure Organisation Infrastructure Management System has been used to determine what Ministry of Defence (MOD) buildings might potentially contain Reinforced Autoclaved Aerated Concrete (RAAC) material, based on the period in which they were constructed and their construction type. HMNB Clyde including Coulport has been included within the assessments to ascertain if they have been constructed with RAAC.
