5D BIM represents the evolution of information modelling, integrating project cost data alongside geometric (3D) and temporal (4D) parameters. By linking detailed cost information directly to the individual elements of the model, it enables the automatic generation of bills of quantities (BoQ) and commercial cost estimates. This approach allows for dynamic, real-time cost control that updates instantly in line with any design revisions. Consequently, 5D BIM ensures the fully integrated, reliable management of quantities, timescales, and expenditure across all phases of the asset lifecycle.
