This Digest provides an overview of the advice given in BRE Report 511 entitled 'Handbook for the structural assessment of large panel system (LPS) dwelling blocks for accidental loading'. It gives guidance to professional engineers and owners on the structural assessment of an existing LPS dwelling block for accidental loads. It explains the fundamental aspects of undertaking such a structural assessment, describing the technical requirements, the objectives, and the sequence of technical activities involved.
