When BIM is described as a process, it translates into VDC. VDC = Virtual Design and Construction VDC is a âverbâ or taking action on BIM. From Mortenson's perspective, VDC is simply a visual management methodology using BIM as part of our proven construction analysis and work processes. Design teams use BIM and Construction teams use VDC right? Wrong... The design team utilize VDC as part of their work processes such as lighting or engineering analysis. The construction team core work processes are scheduling a project, estimating a project and analyzing the design for constructability. Plan the Work, Work the Plan There are two areas of focus for VDC. One is the use of BIM as a virtual prototype to plan work.
