Reinforced Autoclaved Aerated Concrete (RAAC) panels: investigation and assessment

This guidance provides identification and remediation solutions for Reinforced Autoclaved Aerated Concrete (RAAC) planks. RAAC has been used in building structures in the UK and Europe since the late 1950’s, most commonly as precast roof panels in flat roof construction, but in the 1990s structural deficiencies became apparent. This report has been prepared to improve awareness of RAAC amongst the wider structural engineering community and share recent findings to assist those who are asked by clients to advise on the management and mitigation of RAAC panels. It is recommended that the reader also familiarises themself with the 2019 SCOSS alert and the other key references at the end of the report.</p

Reinforced Autoclaved Aerated Concrete (RAAC) investigation and assessment – further guidance

This report provides further guidance on the critical risk factors associated with RAAC panel construction. It includes a proposed approach to the classification of these risk factors and how these may impact on the proposed remediation and management of RAAC. This report is designed to assist with the approach to RAAC assessment amongst the structural engineering community. It is intended to be adopted by structural engineers who will be responsible for quantifying, appraising and providing reasoned assessments of RAAC panel construction on a case-by-case basis using their own engineering judgement. It is recommended that a reader familiarises themselves with the 2019 SCOSS Alert, the previous IStructE report and the references in Section 8.</p

MOESM13 of BMC Ecology Image Competition 2016: the winning images

Additional file 13. “G407 is an immature gannet that was fitted with a unique colored band and a GPS logger, which is just visible on the tail. Steve Votier and I tagged this bird as a part of project run by University of Glasgow’s Jana Jeglinski, which investigates the movements of gannets before they settle down to breed, as very little is known about this 4–5 year period. These solar-powered loggers ‘text’ GPS data via the mobile phone network, so the bird can be tracked in real time until the bird naturally shed the tag as she replaced her tail feathers. After leaving RSPB Grassholm Island in West Wales, a colony of 36,000 breeding pairs, she travelled to Ireland, Cornwall and France!” Attribution: Bethany Clark (University of Exeter, UK)
