A New Approach to Floor Construction Inspections with Imerso

Ensuring quality in floor construction is a crucial aspect of any building project, whether it's a commercial complex, industrial facility or residential home. Imerso’s Surface Analyser lets you conduct inspections on floors and concrete slabs routinely in a more accurate, precise and faster way than ever before. 

In this guide, we’ll show how to use Imerso’s Surface Analyser tool to simplify your process of surface inspection and documentation. 

Ready? Then let's begin!

Eliminate Floor Construction Risks for Projects Success

Defects or any out-of-tolerance elevations and depressions can lead to dramatic problems and costs that worsen further throughout the building's life cycle.

Addressing floor construction risks early in the project will help you to:

  • Improve your teams’ efficiency and productivity, and eliminate delays.
  • Prevent accidents, injuries, and property damage.
  • Avoid legal consequences, including penalties, fines and potential litigation. 
  • Reduce the financial burden associated with worker compensation claims, medical expenses, insurance premiums, and potential project delays. 
  • Ensure high building quality standards for the entire building lifecycle.

By establishing a proactive risk management strategy, you can reach significant cost savings both during the construction phase and in the long run.

Traditional Floor Construction Inspections are Outdated

Manual inspections with level, straightedge rulers, total stations, or similar methods require a lot of time and resources and are often inaccurate or with sparse information. Things get even harder if a project must comply with strict international standards such as the DIN18202 for surface analysis, which require measurement of floor slabs in very specific ways.

Sounds familiar? Well, this problem is very common. 

Months back, our friends and client at Drees & Sommer struggled with this challenge and reached out for our help. They looked for an easy and relatively quick solution to this problem. 

We found it!

We named the tool Surface Analyser, and made it a standard feature in the Imerso intelligent platform for all our clients, as everyone is super excited to use it. 

Surface Analyser leverages accurate As Built data captured from the site in the form of 3D scans (also known as point clouds) and automatically verifies work quality and floor surface compliance. This includes both colour-coded heatmap visualisations of elevations and depressions above your tolerance parameters and DIN18202 measurement grids.

Imerso’s 3-Steps For Ensuring Quality in Floor Construction

Step 1: Load Your Scans into Imerso

To use the Surface Analyser, log into your project and load the scan data of the area you wish to check.

You can check surface flatness against scans made with any scanner, including Leica BLK360, RTC360, Trimble X7, Faro Focus, NavVis VLX or similar.

With the scan data loaded into the Imerso 3D Viewer, you can isolate the floor slabs using the Sectioning tool.

Step 2: Check Your Scans vs BIM: DIN 18202, Slope and Scan Deviation Grids

Now you can start measuring surfaces via:

  • DIN 18202 grid method, which highlights out-of-tolerance segments, so you can focus on and report areas where the floor isn’t as flat as expected. The DIN18202 mode displays a value on each grid segment, highlighting the out-of-tolerance measurements.

  • Slope grid, where both slopes and height differences are shown on the grid. This method allows checking both the flatness and levelness of a floor.

  • Scan deviation grid, a visual method which colour-codes differences between scans and BIM models. One can check whether the surface is misplaced, out-of-level, or uneven. Overlaying the coloured surfaces with a grid measurement makes it easy to report the findings.

For example, with the DIN 18202 grid, you can set tolerance limits to the regulatory standards. If following the DIN18202 protocol, this limit will depend on the stage of construction: 15 mm in grids of 1x1 meter, for unprepared concrete slabs.

Step 3: Document and Report Discrepancies with Details For Fast Resolution in Seconds

Surface Analyser not only checks deviations of your surfaces but also streamlines your documentation process. In the event of problematic surface discrepancies, you can document and report the case in seconds, simply by creating a new issue card directly within the viewer. 

This feature enables seamless collaboration and easy sharing of surface inspection findings with your team. Use it to save valuable resources, and ensure accurate documentation by eliminating the need for time-consuming site visits.
