Book review: How to be a party wall surveyor: a guide to practising under The Party Wall etc Act 199

This month's letters reflect on the Genoa bridge collapse and ask how many other pieces of infrastructure may be unsafe; consider the subsidence problems that may arise from a hot summer; discuss the importance of retaining old building records; and call for better promotion of the industry and careers in engineering through the media.

Sarah Williamson came to structural engineering a few years later than most, but since starting her career she has forged her way to being one of the key minds responsible for delivery of the multibillion-pound main civils work contract at Hinkley Point C nuclear power plant. Jackie Whitelaw went to meet her.

This month's teaser from reader Richard Hollamby concerns a cantilever beam subjected to a uniform live load.
