Short Overview of Initiative How does this initiative work A commitment to delivering the M1 J19 to solve the issue and how was it put into in a BIM environment was made by practice? Skanska and Jacobs. That Why was a different way of commitment was to deliver a single 3D doing things seen as model as part of the new design necessary/a good idea? process to take place. What did you do differently? The objective of the single 3D detailed design model is to provide a final design of all Civil works that incorporates and integrates all the individual design elements (alignment, fencing, safety barrier, drainage, lighting signs, etc). Each individual design layer can be overlaid in the 3D model at any time and checked for clashes. Using BIM as an overall approach to design (full 3D models shared and coordination throughout the design process, based upon BS1192) gave better visibility to other design disciplines and to the other members of the delivery team. A review of clashes at key gateways has been replaced with continuous formal and informal design review processes based entirely upon BIM. The term Clash Prevention has been used to reflect this change in approach. The sharing of the 3D models throughout the design team and the delivery team gave early visibility to Design Options from all disciplines. These are continuously checked against existing assets and against all elements of the design. Rather than waiting for key design gateways to share design proposals, 3D models have enabled rapid and better informed decision making to
