What Is Quality Control in 3D Scanning — Explained Simply

Imagine you're building a house or installing equipment. You've already spent money, time, and energy. But suddenly you realize a pipe is in the wrong place, a wall opening is off, or a structure has sagged.
Quality control is how you make sure everything is done right — before something goes wrong.

What Is Quality Control in 3D Scanning?

It's the process of using a 3D scanner to capture the real-world condition of a structure or object,
then comparing it to the design drawings or BIM model.

Where things are off

By how much

And whether it meets the design intent

Where Is It Used?

s

MEP installations:

Verifying pipes, ducts, and HVAC alignment

Construction:

Checking wall, slab, beam, and opening positions

Miscellaneous 103 expandlines

Manufacturing:

Ensuring components match spec

Restoration:

comparing real-world conditions to historical drawings

Prefabrication:

scanning modules before they are shipped

How Does the Process Work?

1

We scan the object after the work has been completed

2

We compare it with the design model (e.g., in Revit or IFC)

3

We analyze where deviations occur (± mm)

4

We generate a report (PDF or interactive viewer)

5

We deliver the results to the client with highlighted problem areas

What Does the Client Gain?

Clear proof that things are done right

Early detection of potential problems

Cost

Less rework = less cost

Business Vol.2

Documentation for contractors, inspections, or future reference

FAQ

Is this only for large projects?

No. We perform quality control for both large factories and small apartments — whenever precision matters.

What if deviations are found?

We show you exactly where the deviation is and how big it is. Then you decide — to fix it, adjust the plan, or proceed.

Can I compare the scan to a PDF or a 2D drawing instead of a BIM model?

Yes. We can compare your scan to DWG, PDF, or even a sketch. But BIM gives the most accurate results.

Do I need special software to view the results?

No. We can deliver a PDF report or send you a web link to view everything in your browser — no installation needed.

How long does the quality control process take?

From a few hours to 1–2 days depending on the project size and how much detail needs to be checked.

Can 3D scanning-based quality control be used to accept work from a contractor?

Yes. It’s an objective way to verify whether the completed work matches the design. The client gets digital confirmation, and the contractor receives a clear evaluation.

3D scanning-based quality control is a fast, visual, and highly accurate way to verify work.
It saves money, time, and stress — and adds confidence to your project.
