You’ve probably been hearing a lot about Building Information Model and GIS lately. Our senior consultant Robert Krisher shares what CAD data extracted from a BIM application looks like in a GIS database.

After taking a look at the datasets and having a few conversations with the POWER team who had built the BIM model, we were able to come up with a workflow that would allow the engineer to export information out of their BIM system (in this case Bentley Smartplant) in a format we could then load into spatially-referenced feature classes in a GIS database.

We started with a series of CAD drawings of various systems from within the facility, here’s an example of one of the drawings we imported:

We then imported all of these CAD files into ArcGIS, making sure to input the spatial reference of the file along with an insertion point for the file:

After that I then took some additional attribution from the files and used it to populate several attributes on the GIS features that I could use to symbolize or query on:

Finally I was able to take a spreadsheet that contained the locations of various pieces of equipment and get that loaded up into ArcGIS Pro as well. Unfortunately because this data was loaded from a spreadsheet I had to symbolize the features using generic ArcGIS symbology:

At this point I was so happy with how things were looking I ended up doing a little extra credit with some of the folks in our asset management department, and we built a few tools in ArcGIS Pro (and a web application) that allow users to create or view work orders in Cityworks that are associated with these 3-D assets:

I hope you enjoyed taking a look at some of this 3-D data.
