Cost estimating is yet another aspect of the building process that can benefit from computable building information. Computable building information supports numerous building design and construction activities: structural analysis, MEP system modeling, building energy analysis, and specification management, to name just a few. As such, it can be scheduled or quantified as a wall: a building assembly made of real materials. A wall for example, "knows" what it is and how to react to the rest of the building. Model-based Estimating A purpose-built BIM solution like Revit features computable building information that enables a model to be understood by a computer as a building. The paper outlines approaches used to link BIM and costing solutions, and then provides examples of firms who are using Revit ® software products in conjunction with various cost estimating solutions, offering insight as to how information from BIM is benefiting architects, quantity surveyors and cost estimators, and builders-as well as their clients.
This white paper explores how the reliable information held within a building information model can be used to support cost estimating.
