This is Digital Construction

Users define the tolerance parameters they want to use, and Imerso applies those values to the inspection tools.

You can set custom tolerances levels for different element types (eg. structural objects, HVAC, or MEP objects) in your Imerso inspections.

Imerso also allows users to modify the tolerance value during the inspection, and the results will update automatically.

No — You don't need the highest accuracy 3D / laser scanner to use Imerso.

Most of our customers typically run routine construction inspections with tolerances ranging 10-25mm — depending on the object classes they're checking.

New generation devices like the BLK360 scanners from Leica Geosystems (1st and 2nd versions) deliver scan data with 5mm accuracy. These are quite affordable devices and extremely effective and fast to cover 99% of your construction quality verification needs. 

Be aware that higher accuracies and capture ranges in scanning hardware come at a cost. Not just of a higher price, but also of a slower and less agile scanning process onsite. This will hamper your teams' ability to do this as a frequent routine.

From our experience, you'll get much more value from prioritising scanning frequency and agility. So that your teams could easily do it throughout the project. Instead of doing it once or twice with top-of-the-line equipment that only 3rd party experts can handle.

You aren't alone here. The misuse of the terms "accuracy" and "precision" is a constant battle in the surveying community.

For simplicity, you can read that number as the level of "Noise" in the captured scans.

If you capture a wall in your scan, the 5 mm accuracy value of your scanner doesn't mean that the wall object itself is misplaced by that value. Rather, it means that each of the millions of individual point representing that wall may be misplaced from reality by +- 5mm. The lower the accuracy, the more "noisy" the resulting scan.

As a result, capturing larger objects such as structural walls and large HVAC elements is less impacted by this variance. Conversely, capturing small objects like electrical cables and rebar will be more challenging with lower-accuracy devices.

We've built Imerso as a cloud-based platform. This allows our customers to leverage infinite on-demand scaling of servers and computation speed, without investing in expensive local server systems and powerful computers.

This also allows our team to constantly push new feature releases and software updates to keep all Imerso customers on the newest version.

For customers needing a local deployment due to strict security requirements, we can arrange a custom implementation at an agreed fee.
