With recent concerns regarding Reinforced Autoclaved Aerated Concrete (RAAC) in schools, STRATUS9 CONSULTING LTD has stepped up to conduct vital inspections in educational establishments. This blog aims to provide essential knowledge about RAAC and guide schools in addressing related issues.
Understanding RAAC in Schools:
RAAC, a lightweight cementitious material used between the 1950s and mid-1990s, differs from traditional concrete due to its lack of coarse aggregate and reinforcing material. It was primarily used for roofs, floors, and walls in building construction. However, its limited durability and susceptibility to damage make it a potential risk in school buildings.
Identifying RAAC Panels:
RAAC panels have distinct features that set them apart:
- Size: Typically 450mm to 600mm wide and 2.4m to 3m long.
- Shape: Slight chamfer on each edge.
- Color: White to pale grey.
- Texture: Aero-like interior makeup.
- Ease of Gauging: Can be easily dug into with a screwdriver or similar tool.
Five-Stage Approach for RAAC Management:
The Department for Education (DfE) advises a structured approach:
- Information Collection: Gather relevant data about the building.
- Initial Assessment: Identify potential RAAC elements.
- Appoint a Specialist: Engage qualified professionals for a detailed check.
- Detailed Assessment: Conduct thorough investigations if RAAC is suspected.
- Management and Remediation Strategy: Develop a plan to address identified RAAC issues.
Dealing with RAAC in Schools:
If RAAC is suspected or identified:
- Engage a qualified professional for initial checks.
- Follow the professional’s advice for next steps.
- Contact the DfE for guidance and support.
- Explore funding options like the school rebuilding program, condition improvement funding, and urgent capital support.
Contextual Perspective:
While over 150 schools have been flagged for potential RAAC presence, the number is relatively small considering the total number of schools in England. However, the closure of four schools due to RAAC issues underscores the importance of addressing this matter proactively.
