// Overview
The project involved the inspection and structural assessment of RAAC panels within an existing building. The works focused on identifying the presence, condition, and extent of RAAC elements, alongside evaluation of their structural behaviour and support conditions. The assessment considered known characteristics of RAAC, including its low density, limited durability, and susceptibility to moisture ingress and long-term degradation. Observations were combined with current UK guidance to assess the likelihood of failure and determine appropriate intervention strategies.
// The challenge
RAAC presents inherent structural risks due to its brittle behaviour, limited reinforcement anchorage, and potential for sudden failure without significant visible warning signs. Assessing its condition required careful inspection and interpretation, particularly in areas where access was limited or where deterioration was not immediately apparent. The project also required alignment with evolving UK guidance on RAAC management, ensuring that recommendations reflected current best practice and risk-based decision making.
// The outcome
A clear and structured risk assessment was delivered, identifying areas of concern and categorising the level of structural risk associated with the RAAC panels. Practical recommendations were provided, including monitoring strategies, temporary safety measures where required, and long-term remediation options. The outcome enabled the client to make informed decisions regarding safety, maintenance, and future intervention.
