Who's Scanning?

Guess I'll go first, EllisDon is scanning and processing point cloud data and has been doing so for years now. Really hope there are other like-minded companies out there.

We don't scan ourselves currently, but we have used it on a couple projects for different reasons. One was to coordinate a complex geometric entrance to a building. The steel was scanned and then modeled in its exact position. We then used that model to build up the architectural portion to help the fabricators. We have also had mechanical rooms scanned to inform us of the as-built condition. Scanning is much more accurate than measuring by hand, and you don't miss anything. You can always open the data and tour the site virtually, which is very beneficial.

Hi

Thanks for starting this thread.

We focus on developing Asset Information Models (as-built BIM data) here in Switzerland (BIM Facility AG). We use laser scanning as well as drones and other surveying methodologies. I've personally been working with laser scanning and developing workflows for building graphical data from point clouds since 2001. I've worked in UK and Switzerland. It would be interesting to share some workflow ideas for scan to BIM. Are you using laser scanning for capturing Survey Information of existing assets and are you also using it for BIM 2 Field applications (or capturing the as-built geometry during the construction Phase)?

Kind regards

Patrick

Hi Patrick,

Yes to both of your questions, we've been scanning for many years now and are always on the lookout for new/better ways to squeeze every last drop of potential out of the data. Existing conditions scanning (with or without scan-to-BIM), as-built conditions scanning during/after construction, etc.

I worked for a metal siding/cladding company, and we installed aluminum composite panels. Had some problem using laser scanning, because sales representative told me to go look for the two endpoints of the distance I wanted to measure in the software, and well this was not precise enough, because once you zoom in, in a group of points to pick the point, it’s not clear what you are measuring, and there are just too many points clustered together so you don’t know which one to pick. I would love to hear from you guys which applications you use to adapt the information from the scan to a 3D model so that it can be a true representation of the built environment. It’s important to mention that I was looking for a 1 to 2mm precision.
