Mr. David O'Brien:

We have well-established reporting structures on costs as a project is developed through the different review gates. Digital will also be a key component in building information modelling to have the data-handling capacity because, obviously, on a construction project there will be myriad different materials. It is hand in hand between the digital adoption, which we have also commenced this year starting with large projects, along with the reporting structures and the increased level of data that will come on stream between the regulatory obligations and as we start to incrementally apply this.
