Building contract – Construction claim. The Technology and Construction Court allowed the defendant engineering firm's application for an order requiring the claimant to answer a request for further information concerning advice given by the claimant's expert at the time when it had decided to undertake remedial work in respect of a luxury development near Harrods. The claimant had brought proceedings against the defendant, alleging that it had failed adequately to design basement walls for the development. The court held that the claimant should answer the request where it was at least arguable that some of opinions of the claimant's litigation expert had been taken into account by the firm of engineers, upon whose opinion the claimant had based its decision to carry out the remedial work.
