    Shopping Centre Water Ingress – London

    Client: Building Owner

    This matter involved the refurbishment of a 1960s mixed-use retail, residential and cinema development with basement car-parking in central London.  Various issues including ponding and water ingress were affecting the development.

    The Building Owner initiated a claim against the Developer and the Design & Build Contractor, and engaged WJM&P to determine the cause of ponding and leaks, the likely scope of remedial works required, and the roles of the various parties involved.  We carried out detailed surveys of the leaks and inspections of exposed areas of the construction to analyse the adequacy of the construction and pattern of the leaks.  We also commissioned laboratory tests to analyse the composition of various construction materials and deposits, and engaged specialist drainage consultants to analyse the siphonic drainage system used.  We prepared advice on the appropriate remedial works and commented on an extensive programme of works by others.  We conducted extensive reviews of industry guidance, archive documents, witness statements and other evidence and prepared an expert report for exchange.  We attended experts’ meeting as part of a Mediation.

    The matter was settled in negotiations following the Mediation.
