The following note has been prepared by Mr. T. N. W. Akroyd, MScTech, LLB(Hons), CEng, FIStructE. MICE (Vice-President), who appeared as an expert witness for the London Borough of Merton when the claim was heard for damages and consequential loss arising from subsidence damage at the block of flats in South West London. In the event, as readers may recall, the parties settled the case out of Court. Mr. Akroyd's review emphasises again the responsibilities of the chartered structural engineer. They have always been onerous; recent cases have neither added to nor subtracted from them.
