We've recently been using optimisation tools. They're called genetic algorithms and they are used to optimise multifaceted problems. When you applied them to some mundane jobs, it wasn't groundbreaking, it didn't change the whole project, but it did make a marginal gain - it knocked off 10% reinforcement. If every job did that, that's a huge saving in embodied carbon for our industry. It needs to start from education, the way people teach you to be an architect, teach you to be an engineer, teach you to be a surveyor. It's still traditionally, not digitally, led. So, when people enter the industry they start to do it in an old-fashioned way as there is not the digital skillset.
