Material TakeOff : this option allows to measure all different materials included in a certain category or even all Revit categories by a Multi-Category table.Using quantities table is not a good a idea to select Multi-Category table because you will only be able to add common parameter to all Revit categories (which are very f ew). Quantities Table : it can measure different categories elements and its parameters.To generate all the quantities there are two differentiated options: All through the modelling process you should be thinking about quantity TakeOff for budget so you take coherent decisions, Revit families and elements should be thought to be measurable and budgetable. When using a Revit model to generate Quantities you need to have developed a consistent model with enough construction elements definition. Procedure 1 Creating Quantity or Material TakeOff Schedules We will explore how to use a model-based estimating workflow to provide useful cost feedback to the project team and inform decisions during all phases of design, from inception through construction.įirst step in the project is to get conceptual estimates and compare the cost of proposed alternatives, and prepare preliminary estimates based on quantities of key building elements to confirm cost feasibility and evaluate proposed design changes. txt file exported that can be opened with a Microsoft Office© tool like Excel©. On this Guideline we will describe the workflow from Revit Material TakeOff and Quantity Schedule to. User fully understands data structure in models (category > family > type > instance).User has basic skills in BIM modelling with Revit Software, and understands the language used.Understand that Quantity TakeOff can be bi-directionally from model to external schedules and if necessary from them to the model with extra information.Understand workflow to generate Quantity TakeOff from Model without using any other Software than Revit and Excel Office ©.
Understand how to use preliminary Cost Estimates to study different project design options by comparing conceptual masses estimates.
