Here’s a brief project description on how we model and take quantities in Revit for a Building Information Modeling (BIM) project:
- Project Setup: Starting by setting up project in Revit. Define the project location, units, and any other necessary project information.
- Import AutoCAD Files: Start by importing the AutoCAD files (.dwg) that contain the architectural and other relevant information into Revit project. Revit provides tools to import and link AutoCAD files, allowing us to leverage existing drawings and information.
- Architectural Modeling: Begin by modeling the architectural elements of the building such as walls, floors, roofs, doors, and windows.
- Structural Modeling: If the project includes structural elements, model these in Revit as well. This may include columns, beams, slabs, and foundations.
- Systems Modeling: Model mechanical, electrical, plumbing, and other systems within the building. This could involve ductwork, piping, electrical conduits, and fixtures.
- Family Creation: Create custom families or components as needed for specific elements that are not readily available in Revit's default library.
- Detailing: Adding furniture, fixtures, equipment, and other elements to complete the design.
- Parameterization: Assign parameters to model elements to capture relevant information such as dimensions, materials, and quantities. This information will be crucial for generating accurate quantity takeoffs.
- Quantity Takeoff: Once the model is complete and parameterized, We use Revit's scheduling tools to generate quantity takeoffs. Create schedules for different categories of elements (e.g., walls, doors, windows) and extract quantities based on the parameters assigned to each element.
- Validation and Review: Review the quantity takeoffs to ensure accuracy and completeness. Make any necessary adjustments to the model or parameters if discrepancies are found.
- Documentation: Use the quantity takeoff data to generate project documentation such as bills of quantities, material lists, and cost estimates. This information will be valuable for procurement, construction planning, and project management.
