One of the most important features of estimating in BIM is its capability to explain building data through a 3D visual model. This representation gives its users a clearer understanding of a building project and reduces the chances for missing or misrepresenting components. Traditional costing applications by their nature have been text‐oriented – listing, tabulating, and calculating lists of component assemblies.
In the current market, improved estimating applications are available for BIM‐based costing that offer a robust interface for visually manipulating the model and its components for costing purposes. The estimating software application needs to build in a Revit’s visual interface to compose a graphic interface for interactive costing analysis.
The capability to visually select objects to quantify or display building components by user‐defined
groups (be it CSI formats, phase, or composition) with colour coding offers the estimators a power tool to perform more informed decisions and investigate multiple what‐if scenarios. Contrary to being replaced by technology, cost estimators will find their roles enhanced, freed from the tedium of quantifying with more time to perform higher level duties.
