Tristan McDonnell served for many years on the buildingSMART International Infrastructure Room. We discuss this as well as his responsibilities being a Director at ARUP. We recall the experiences developing openBIM standards for infrastructure and the positive impact that IFC 4.3 is going to have on the industry. We also cover the importance of aligning to the bSI Strategic plan and the role this community has with industry thought leadership. And Tristan shares his experiences of selecting, then applying, robust sustainability solutions to an aging home.
