I've been at Arup for just over 25 years.' For the first 10 of those years, I was a mechanical designer.' I then gradually transitioned into sustainability, although still with a strong focus on engineering.' I worked for several years in our Building Performance team, focusing mainly on performance improvement for existing buildings and portfolios.' This time working on buildings in an asset management context was invaluable, and something I would advocate for all building services designers to spend time doing.' It gave me a very different take on the design process having seen how buildings are operated and used, what works well and most importantly what doesn't.' The culmination of this period was a research project that I led, working with experts both from Arup and from the FM industry, looking at how digital technology could revolutionise facility management.'
