Digital Takeoff

How to perform digital takeoff with ViewCompanion

Digital takeoff, also known as electronic takeoff or digital quantification, is a process in construction and related industries where measurements and quantities from construction plans are performed digitally using specialized software. This is a departure from traditional manual methods, where estimators and construction professionals would use paper plans and manually measure quantities.

You can use the annotation measurement tools available in ViewCompanion to perform a digital takeoff and export the result to Excel.
In this short tutorial we will show how to do a takeoff based on a floorplan, and we want to measure the area for each room.
The picture below shows ViewCompanion displaying our floorplan with the markup tab active where you will find all the available annotations tools:


Floorplan

Before you can begin to measure you will need to setup the correct drawing scale. The floorplan above was created with a 1:40 scaling and this is as you can see selected in the status bar at the bottom of the screen. If the scaling is not displayed somewhere on the drawing, you can also use the calibration tool, please open the help by clicking F1 inside ViewCompanion for more information about calibration.
The measurement unit (metric or us) can be selected in the status bar. For this tutorial we will use meter as our measurement unit.
Just above the status bar you will see a pane named Markup Element List, and when you start to add annotations, they will all be listed here. Additional information like date, text, area and more will be listed too.
To the right of the screen, you will find the markup property pane. In this pane you can setup additional data that will be added to created annotations. In the picture above we've setup the height to 2.70 meter. This value is useful if you want to calculate wall area and volume for added measurement areas. You can define your own category here as well if needed, and You can use the markup layers to separate annotations, for example using a layer for net area and one for gross area.

Commonly used tools for takeoff are the measurement area and count tools. To add a measurement area, you press the Measure button, and then select one of the following tools:

Measurement polygonal area
  
Measurement rectangular area

The first tool to the left is used to draw a polygonal area. The tool next to it, is faster to use if you're measuring a rectangular area, for example a room. If your drawing is of PDF, DWF or PLT file format you will also be able to make use of snap to drawing geometry for higher accuracy.
In the picture below we've used the measurement area tools to measure all the different rooms, and the markup list at the bottom will show information about all the areas.

You can check the summary for the currently measured areas by clicking the Measurement Summary button in the Markup Element List toolbar, this tool has the following icon:

Measurement Summary

The dialog shown below will then be opened. Here you can see the summary of all the areas based on selection. It is possible to include all measurements, only those on a specific layer or only those belonging to a certain category. Categories are user defined, and you can use the Markup Properties settings (see above) to add this information while you add the areas.


Measurement summary dialog

Use the Save Report button found at the bottom right of the dialog to export to Excel and then open the created XLSX file in Excel:

How to count items

You can use the annotation counter tool to count items in the drawing, for examples items like doors or windows.
To start a count, you select the counter tools found in the Markup Tab:

Measurement counter tool

After selecting the counter tool, the following dialog will appear:


Counter settings

Using this dialog you can select the color, shape and size used for the count indicators. You can also add a label that can be used to identify what you're counting. In the picture below we've counted two different types of doors found in the floorplan using different colors, shapes and labels:
