What is 5D BIM?
5D BIM connects the model to cost: quantities extracted from model elements link to unit prices so the estimate updates as the design changes. Cost is the fifth dimension, after 3D geometry and 4D time.
In practice
The promise is live cost feedback during design; the practical constraint is model quality — 5D is only as good as the modeling discipline behind it. Model-based estimating tools automate the quantity-to-cost mapping.
