For each mass floor, the software calculates the floor area, exterior surface area, volume, and perimeter.

You can use mass floors to divide a mass based on defined levels. In addition, to generate a quick building cost estimates you can use conceptual mass to create a simple model which allows us associate mass construction elements to a tabulate key quantities to generate first approach to budget. You can also do this operation using the spaces volume in which case the cost value will be more accurate.

Using spacesĪ easy way to generate a first approach to cost estimation is to create building spaces and add a new space parameter you can name Cost per Unit Area, and then a calculated value which will be the result of multiplying this new parameter (defined by established cost tables estimations) and the area of the spaces. For this reason, cost estimates based on the area or volume of a proposed conceptual design and comparison to historical data for facilities with similar functions and programming are especially valuable for confirming that the design is accurate and in accordance with the owner’s proposed project budget. Rough cost estimates for the exterior of the building, based on linear dimensions or surface area.Ĭost analysis is most beneficial in the early design stages of a project, when design decisions have the less impact on the project and they are easier to implement.The best mix of uses (such as retail, residential, and office space) for the building.You need to be careful using this kind of table and ensure materials are correctly applied to families and categories.ĭuring the early planning stages of a building project, you can analyze the conceptual design in several ways and for various purposes: 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 how to use preliminary Cost Estimates to study different project design options by comparing conceptual masses estimates.
  • Understand the process to generate Quantity TakeOff from the model in order to generate the project budget.
