The surveying profession has already weathered 145 years, even if few members of the general public could tell you exactly what they do. The Royal Institution of Chartered Surveyors (est.1868) has not, however, made it this far by being complacent. It commissioned a report looking at how the world around it might change over the next 30 years, which points out that 25 years ago, the Berlin wall was still standing, the internet was a distant dream and hardly anyone was talking about globalisation. Conversely, we have no idea which of our current preoccupations – from climate change and the collapse of global economic structures, to Building Information Modelling and higher university tuition fees – will have the greatest impact in the decades to come. For the danger-themed April issue of the RICS’ magazine, Modus, I interviewed six senior surveyors about the threats facing the profession, confronting prolonged recession, technological obsolescence and even extinction.
