<p><b>Point cloud to Revit - TRANSCRIPT</b></p> <p><b>Robert Bourdages</b>: My name is Robert Bourdages, I work in the Buildings group at Stantec. I’m a discipline lead, and I have over 30 years of experience in the structural design of buildings.</p> <p>We used to make as-built drawings, which are a reflection of what the real conditions are, by two people going out to a site and measuring with tapes, so we’d measure horizontal control and vertical control.</p> <p>Accuracy as good as you can pull a tape and read it. And, uh, you’re only taking selected areas, so you might have sampling errors as well. So reasonably accurate, but not great.</p> <p>Laser scanning is a big improvement because what you’re doing is you’re capturing every two or three mils on every surface, as opposed to taking select, random samples of dimensions, and also because the tolerance is so great, up to two or three milimetres in accuracy, so you get <i>terrific</i>, very accurate documents.</p> <p><b>Matt Falacinski</b>: The Point cloud-to-Revit translation process is all about bringing in the information into Revit accurately, understanding what it represents, and being able to trace the points and convert them to 3D model elements.</p> <p>We’ve used this process for a Ben and Jerry’s factory down in Vermont.</p> <p>We’ve done this for an Anchorage Airport where they were looking to do renovations</p> <p>The Calgary Police Station, we were doing renovations to their central office, so we were able to send our teams out there to collect all the data, that data gets sent back to us here in Edmonton, and we were able to use that data and convert it into a revit model, and then we sent that out to the architects so they could demonstrate what their plans are for the renovations.</p> <p><b>Robert</b>: The vast majority of the work that we do now is used with this point cloud technology, because it’s faster, it’s more accurate, it’s less cost, more reliable.</p> <p><b>Matt</b>: I think point cloud-to-revit translation is a no-brainer when it comes to doing renovation projects. If there are any projects that you need to capture interior dimensions, exterior dimensions, and convert that into a revit model, this is the quickest, most accurate way possible to do it.</p> <p><b>Robert</b>: I believe that the reason that many architects don’t use it is because they don’t know that the technology exists, they may not understand the technology, they may not know the cost of it, and I think once they would understand how it is available and what it can do, I think many more people would use it.</p>
