What is a Deviation Report?

A Deviation Report is a convenient way to quickly identify how your staked points align with the design. Deviation reports can be used in many ways, but a good example where they are commonly helpful is when users are verifying anchor bolt locations for steel: are the embedded anchor locations in the correct location? Before steel gets installed, a report can be made indicating which anchors are in or out of tolerance.

Below are other common ways deviation reports are useful:

1. Quality Assurance and Compliance (obtaining as-built data)
2. Early Detection of Errors (correct issues before they escalate)
3. General Documentation (track progress)
4. BIM Integration (integrate as-built information into digital designs)

How to Prepare for a Deviation Report

For a deviation report to be possible to obtain, first you must have "staked" data within your file.

Staked data is achieved when you are in point layout and you press the "measure" button after laying out a point. As you "stake" each point, the staked data of that point is saved in the background for you to export via a deviation report, or when exporting general point information.

See this article to understand point layout (staking points), and this article to understand how to import and export point information, in general.

 Below is the measure button you must press during point layout in order to ensure staked data is obtained:

How to Export Deviation Reports:

Step 1: Navigate to the Reports Tab

Find the Deviation Report export available under the reports section:

Step 2: Assign your Preferred Template

You have the ability to edit the template and export type of your deviation report

Step 3: Edit your Template (if needed)

You have the ability to press the "edit template" button to edit information found in the header and footer of your deviation report:

Step 4: Export the Deviation Report

Simply press the green check marks until you are able to save the deviation report at a location of your choosing on the tablet.

How to Understand the Data in a Deviation Report

The data is organized to quickly see errors:

• Points that are staked are labeled with a "_Stk" in their suffix
• Both the layout point and the staked point's coordinates are easy to find and compare
• Red text with yellow triangles appear for any point that is staked outside of your designed tolerance
  • Please see this article to understand what tolerance is and how to set it.
• When exporting this as an excel file, you can adjust and format the data as you please.

In the below screenshot example, the tolerance was 8mm on layout, and 11mm on height. The software identified the errors where my points were staked out of tolerance compared to the design:
