This presentation will discuss the design and of University College London Hospital Proton Therapy Center – one of the first developments of its kind in the UK. Both CampbellReith and Scott Tallon Walker have been working on this project from the earliest days and Bouygues was chosen as the Main contractor in 2015. As this project has matured, so has the BIM environment and consequently the client BIM requirements. From the beginning this has been an ambitious BIM project – attempting to have a fully coordinated building with models from MEP, Structure, Architecture, Façade manufacturer, Drainage, Specialist Proton therapy supplier, Contractor and more. There have been many challenges along the way, both in terms of construction and design, but in working together as a team we have addressed them to deliver on the client’s brief. We will discuss the architectural, structural, and construction challenges we have faced along the way and how we have addressed and resolved these. We will discuss the data outputs and how we have addressed the developing client brief to ensure we are delivering to client requirements without impacting on deadlines or coordination. Speakers: Chad Bedard – CampbellReith (Consulting Engineers), Michael Earley (Scott Tallon Walker), Lewis Wenman (Bouygues).
