Two of these features are the distillery’s removable roof and walls. “The client was concerned about the environmental impact of the eventual replacement of the fermentation units,” says Buckingham. With help from Autodesk BIM solutions, AECOM created a unique, flexible structure that will allow Diageo to remove the walls and the roof when the time comes to replace the fermentation units. This involved creating a combined 3D model of the structure, architectural façade, building services, and processes to help see if that the fermentation units could be removed in the future with minimal disruption.
