This paper is discusses the need for the construction industry to embrace digital technologies and how Building Information Models (BIM) provides a collaborative framework for project delivery, construction and in operations management that can be used throughout the entire life-cycle of a project. It considers the concept of the digital twin and the British approach to the three levels of BIM, from level 0 through to level 3. Level 0 is the traditional unstructured and paper approach to design and construction. Level 1 is supported by simple Computer Aided Design (CAD) and uses lines, shapes and text to produce 2D drawings and text schedules. BIM level 2 builds on level 1 CAD but incorporates additional information associated with objects, including cost and time. BIM level 3 is expected to provide fully intelligent, interoperable and integrated design, delivery and asset management in 3D. The digital twin concept is explained in the paper and how this will support BIM level 2 and 3, as the virtual model of a project will be a replica of the real world facility. The digital twin will allow us to test and evaluate scenarios in a safe environment and better predict the outcome of changes, whether manufactured or naturally occurring.
