Demolition and rebuilding agreed for RAAC properties
Council homes affected by RAAC (Reinforced Autoclaved Aerated Concrete) in Aberdeen are to be demolished on safety grounds – followed by a rebuilding programme. Read more here.
Various concerns have been raised about the use of a type of concrete in the construction of public buildings known as RAAC (reinforced autoclaved aerated concrete). RAAC is a lightweight material which was used mostly in flat roofing between the 1950s and 1990s.
Aberdeen City Council has been aware of concerns about the use of this product and has previously conducted a range of surveys and inspections of buildings to assess whether these buildings have this material present. This work has identified several properties which have RAAC within their construction.
The Council has concluded the RAAC roof surveys throughout the wider council housing estate. We can confirm that the only properties containing RAAC are those previously reported in the Balangask area of the city.
Several long-term options were explored for local authority properties:
Option 1: not viable (Adding timber runners to extend the bearing length at the support walls).
Option 2: Install a support timber frame under existing RAAC roof panels.
Option 3a: Removal of RAAC panels and replace roof only.
Option 3b: Removal of RAAC panels, replace roof and refurbish homes to modern energy efficient standards.
Option 4a: Demolition only.
Option 4b: Demolition and build new homes.
On Wednesday 21 August 2024 a detailed appraisal (item 9.1) was considered by Council, alongside an overview of feedback from the recent engagement with council tenants, private tenants, owners and the wider community, and associated survey work.
In light of the decision to demolish and rebuild taken at the meeting, the FAQs below will be revised and updated. The aim of rehoming all council tenants on safety grounds by the end of 2024 is unaffected.
