Why Saudi Arabia’s The Line is a terrible idea | Katie Kelleher: ‘Yes, women can operate cranes’ | Robot prints plans right on the floor

Welcome to the third episode of the 21CC podcast, brought to you by the Chartered Institute of Building (CIOB). This month we explore why a line is the worst possible layout for a planned new city in the desert. Pioneering female crane operator Katie Kelleher tells how she started out in construction and explains why women are just as capable. And we visit a construction site using a robot to print plans right on the concrete floor. Digital twins is the topic for this month’s Jargon Buster.
