Leica UC Day 2

I had hoped to get this out yesterday but the “red eye” did me in. The quality and breadth of presentations continued on day 2, along with the outstanding networking opportunities.

One of the most sophisticated uses of laser scanning in the construction arena was discussed by Samir Emdanat, Director of Virtual Design and Construction at Ghafari Associates LLC. As his title implies Samir and Ghafari are leaders in the application of 3D technology as well as in the use of IPD – Integrated Project Delivery, BIM and lean business practices.

They see laser scanning as a risk management tool and 3D as way to increase certainty. Their goal is to build the 3D model by making construction a process of assembly. Unfortunately they stated that 3D is not working very well, but change of this magnitude takes time. They are using Navisworks to do the analysis.

John Russo, CEO and Founder of Architectural Resource Consultants is in the building survey business. He creates what he calls laser as-builts. John pointed out the challenges of working with today’s CAD software that only understands ideal “ortho” walls, floors and ceilings. He noted that BIM authoring tools are limiting the level of accuracy that can be delivered.

Adam Horn from HNTB presented their use of laser scanning in a water treatment plant. He noted that the high level of detail that laser scanning produces is often not desirable – it is overkill. He likes the ability to show people rather than tell them about a field issue. This is where they are finding real value.

Kelly Cone from Beck Architecture discussed the challenges his group and the others who have the GSA laser scanning IDIQ are facing. He believes that the GSA has decided that they cannot afford to use laser scanning. He was suggesting the use of alternative methods of data collection such as the use of digital photography for those applications that do not require the high accuracy of laser scanning. His bottom line was to reduce costs you need to reduce the number of scans.

Next time a look at BlueView Technologies a company that is doing underwater 3D imaging.

  • Gene: great to meet you at the conference. I just wanted to clarify one thing in your summary related to 3D. I don’t think we ever intended to say that 3D is not working very well. None of what was achieved on the project would have been possible without 3D technologies. The tools are very sophisticated and capable. Our point was that the various 3D tools evolved to serve specific needs and solve specific problems but the industry can benefit greatly from more integration and interoperability among the various discipline tools.
