Learn how to identify, assess, manage and remediate reinforced autoclaved aerated concrete (RAAC) defects in buildings.

To be able to advise clients on RAAC in their buildings, it is necessary to have a detailed understanding of its properties and common issues and how to deal with defects. 

The course is made up of 3.5 hours of video content and delivered by experienced practitioners. Using case studies and examples, the course provides a detailed understanding of RAAC’s properties, the possible defects, how to investigate, assess and report on it and how to manage or remediate it. 

Course outline 

  • Module 1: History, design standards and defects of RAAC 

  • Module 2: Surveys and investigations, assessment, reporting, health and safety, report writing 

  • Module 3: Remediation, monitoring, and risk mitigation 

Each module contains bite-size recorded presentations from our expert contributors, which can be stopped and rewound at any point. Altogether, it takes half a day to work through all three modules. However, each module can be completed in stages, so you can work at your own pace. 

Learning outcomes 

By completing this course, you should be able to: 

  • Describe what RAAC is, its properties how it was historically designed and manufactured 

  • ​Understand where RAAC may be found and how to identify it 

  • ​Investigate, assess and report on RAAC

  • Apply best practice for ongoing management and remediation 

  • Recognise the role of the engineer in managing risk 

Intended for 

  • Structural engineers wishing to increase their understanding of RAAC 

  • Engineers engaged in the assessment and management of RAAC in buildings, wishing to refresh their knowledge 

  • Built environment professionals and working with Structural Engineers involved with RAAC
