BIM & Autodesk Quantity Takeoff
OMAR SELIM
BASIC CONCEPTS AND PRINCIPLES• The 2D CAD platforms mostly use lines to represent all elements, as shown in
the figure.
CAD project created using 2D lines and curves
• In Autodesk Revit, you can create a building model using 3D elements such as walls, floors, doors, and windows, as shown in the figure.
Autodesk Revit project created using parametric building elements
BIM
• Keep documentation coordinated and consistent with parametric change management technology.
Introduction
What is Autodesk Quantity Takeoff?
Autodesk Quantity Takeoff allows mix of old and new practices Old: Manual takeoff, tracing and measuring New: Automated takeoff, extract intelligent data from BIM
Manual Takeoff and Automated Takeoff workflows can be combined in a single project with ease.
Takeoff Catalogs can be saved and reused across projects.
Various reports readily available.
Introduction continued
Quick and easy creation of assemblies and override of values in an Excel like manner.
Automatic cross referencing of elements across model and sheets
Export to DWF/DWFx including full BOM
DEMO 1: Manual Takeoff – tracing & measuring
Here you will be introduced to the following concepts
Reuse of catalogs Setup of raster image for accurate measurement Quick measurement of lengths and areas, plus counting of elements Adjustment of values in workbook with
Direct overrides Formula
Creation of new takeoff assemblies Saving back the augmented catalog
Approx time 20 minutes
DEMO 2: Starting to use intelligent data
Here you will be introduced to the following concepts
Navigating and previewing model in Autodesk Quantity Takeoff
Perform quick takeoff by picking individual elements Grouping similar elements using a targeted search Performing takeoff on entire model and subsets of model
Navigating sheets and model using cross-referencing of elements provided by above techniques
….
DEMO 2: continued
….
Overriding data explicitly or modifying with formulas
Using assignments for vastly improved productivity
Approx time 20 minutes
DEMO 3: Adding richness to the data
Here you will learn about
Defining types for model takeoff Manipulating assemblies to get real world quantity values Adding cost data for
Materials Equipment Labor
Approx time 20 minutes
DEMO 4: Sharing Your Results
Here you will learn how to
Apply Legends Publish to DWF/DWFx with full BOM data Generate Material Reports Exporting data to other applications
Approx time 10 minutes
Takeoff in minutes automatically—Perform a takeoff on an entire building information model (BIM) in just minutes through integration of 2D and 3D design data.
Greater flexibility than typical databases or spreadsheets—Perform interactive examination of 3D models for material cost estimating purposes.
Dynamic counting—Count and quantify design data quickly and easily.
More efficient manual takeoff—Supports the takeoff of JPG, TIF, PDF, and other “nonintelligent” image formats.
Share, query, and clarify—Generate quantities linked to specific objects. Mark up and “round-trip” your comments.
Faster and more insightful quantity reports—Create summaries and detailed quantity surveying reports quickly and easily.
