A purpose-built BIM solution like Revit features computable building information that enables a model to be understood by a computer as a building. A wall for example, "knows" what it is and how to react to the rest of the building. As such, it can be scheduled or quantified as a wall: a building assembly made of real materials. 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. Cost estimating is yet another aspect of the building process that can benefit from computable building information. Assessing the cost to build it is the domain of estimators. In general, the architect’s scope of work doesn’t extend to material take-offs or cost information. That’s left to the estimator who can use REVIT to calculate Costs.
Unit 1: Introduction How Models can be used for costing
Unit 2: Definitions, Tagging and Cost setup Defining AREAS, ROOMS (by their names e.g. kitchen, dining etc.) Tagging all Walls, Windows, Doors Setting cost of wall and floor per area, setting cost of material per area, setting cost of door, window
Unit 3: Using Schedule Quantities, Formulae Material Take off and Quantification Using SCHEDULE QUANTITIES Creating formulae to create the tables of QUANTITIES and COSTS of all walls, windows, doors, floors etc. MATERIAL TAKE OFF: Calculate the cost of walls and floors per material area QUANTIFICATION: Calculate the costs per areas and export the data in MS EXCEL Formatting
Engineers, People working with cost estimates in the construction industry and Quantity Surveyors

· Define, tag and setup cost for various elements
· Use Schedule Quantities
· Create formulae for cost calculation
· Use the Material Take Off and Quantification Menu
· Export Costs in Excel
