BIM-based incentive system for construction projects developed

In major projects, design changes are hard to track across many model states and thousands of components. For a major healthcare project, Competitio developed a BIM-based method that makes design changes objectively measurable.

At its core, a change rate is computed from the planner's BIM model states. Components of two model states are matched automatically and checked for relevant changes to shell and façade; purely formal software artefacts are filtered out. On this basis, design stability can also be anchored contractually – for example through a bonus model tied to the measurable change rate rather than expert opinion or negotiation.

The method was validated on real building models with more than 15,000 components and combines contract design, game theory and BIM data analysis into a practical tool for project owners.
