5D BIM

5D BIM describes a BIM dimension, which refers to the level of information stored alongside or integrated within a modelling environment. 5D BIM describes a modelling environment beyond basic 3 dimensional geometric model on the X, Y and Z axis, over and above allowing 2D information or drawings to be produced with associated information, from cut-throughs of the 3D model. 5D BIM has other information related to the construction project itself, in particular costs information.

5D BIM includes 4D BIM information but also stats that include (to varying degrees) construction quantities and cost information, thus allowing better costing estimates and in turn the promise of better cost management. It is important to establish the basis and responsibility of the cost information within the project set-up, such as establishing if costs are pre-tender estimates or a record of as-built costs, what methods are used and if operational costs are included.

Today where 3D BIM as an industry standard, with 4D BIM as the next step followed by 5D in the context of models of increasing complexity before 6D BIM and 7D BIM. There are also potentially 8D, 9D, 10D and 11D, though these are not generally formalised or standardised and as such recognised as known dimensions.
