1. BIM & Autodesk Quantity Takeoff
OMAR SELIM

4.  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

5. •
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

6. BIM

7. •
Keep documentation coordinated and consistent with parametric change managem

11. 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.

12. 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

13. 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

14. 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

….

15. DEMO 2: continued

….

Overriding data explicitly or modifying with formulas

Using assignments for vastly improved productivity
Approx time 20 minutes

16. 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

17. 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

18. 
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.
