Virtual design and construction (VDC)
Also: Virtual design & construction
Quick definition: A project management method that uses integrated, multidisciplinary models of the product (the facility), the organization and the process to plan and control a project against explicit, measurable objectives.
Explanation
Beginner explanation
BIM describes the building; VDC uses that description, along with a model of who is doing the work and a model of how and when it will happen, to run the project better. A VDC team sets clear goals — for example "reduce RFIs by 30%" — and measures progress toward them every week.
Technical explanation
The term was developed and formalised at Stanford University's Center for Integrated Facility Engineering (CIFE). In the CIFE framework, VDC uses computer-based models of the product, organization and process (sometimes abbreviated POP) that share data, so that a change in one is reflected in the others. Models are used to predict performance, and predictions are compared with measured performance against publicly stated business objectives.
In practice, VDC programmes typically combine BIM with collaborative planning (often lean methods such as pull planning), integrated concurrent engineering sessions, and metrics tracked at project and production level. Many general contractors use "VDC" as the name of the department that runs BIM coordination, 4D scheduling, quantity take-off and field technology; that organisational use is broader and less precise than the CIFE definition.
Practical example
A general contractor building a hospital wing sets three VDC objectives: complete MEP coordination two weeks before each level's rough-in, keep model-based quantities within 3% of procurement quantities, and cut coordination RFIs by a quarter compared with the firm's previous hospital. Weekly coordination meetings review clash trends, a 4D model checks crane and laydown sequencing, and the metrics are reported to the owner monthly.
Why it matters
Without explicit objectives and metrics, model-based work can become an expensive deliverable with unclear value. VDC ties the modelling effort to measurable project outcomes such as schedule reliability, cost certainty and safety.
Common confusion
VDC is often used as a synonym for BIM, especially by contractors. The distinction worth keeping is that BIM concerns information models of the asset, whereas VDC adds organization and process models and a management cycle of objectives, metrics and improvement.
Historical context
CIFE researchers John Kunz and Martin Fischer documented VDC themes, case studies and implementation suggestions in CIFE Working Paper WP097, which went through several revisions.
