I think innovation, which is important for the public sector, is often centred on the things I'm talking about. Building something so that it survives the two years until you walk away as a builder is a whole different mindset from designing something that you know you're responsible for, for 30 years. We innovate to ensure that we achieve a whole-life view of the asset. I think that's the important area of innovation.
There are also design innovations regarding better functionality of the facilities as well. That's another area that we work hard at.
