I’ve worked with Andrew Derbidge for over 15 years , on multiple projects. The projects ranged from residential alterations and additions, through to public buildings for local government. 
In every instance Andrew provided concise and considered structural Engineering solutions, that were not only practical, but respected the architectural design intent. When it came to justifying a structural approach to a client or builder, Andrew would often go the extra distance and provide thoughtful and clear explanations. I can highly recommend his services.
