Why Verify the Slab Elevation Profile?
Verifying the slab profile immediately after the pour can help avoid costly rework, delays, and wasted material during flooring and partition installation due to under- or over-poured areas of the deck.
What Documentation is Required?
For optimal results, a 3D Model of the finished slab profile should be provided. Accepted file formats include: .rvt, .dwg, .obj, .stl
Note: If the project does not have a model, a reference elevation can also be provided for Siteaware to verify against the scan results.
When should the scan be performed?
The scan should be performed after the pour as soon as the concrete is set enough to be walked on
What scan equipment is required?
The achievable accuracy depends on the scan method and surveying tool, as shown below:
| Capture Method | Total Station GCP Survey | RTK GCP Survey |
|---|---|---|
| Drone | ½” | 1” |
| Lidar | ¼” | ¾” |
Note: The Z (Elevation Coordinate) provided as part of the GCP coordinates MUST be in the same coordinate system as the model or reference elevation provided for verification.
Otherwise, Siteaware will only be able to provide a topographical map of the slab profile.
How long does it take to process a Slab Elevation Scan?
Scan results will be provided before the next business day
How will the report be delivered?
Results will be posted on the Siteaware platform to the Core Overview page
