Hexagon 2012 – Day 2

Day two of Hexagon 2012, and the conference has started literally with a bang. I was blown away by the opening pyrotechnics, lasers and blue/green men; one of whom sneaked up behind me and made me jump out of my skin! The message of embracing change, speed of life and technology came across very clearly and, I think, resonated with the people in the room who are looking to push their own businesses on to survive and hopefully prosper.

Having kicked off the HDS track at 13:30 with my own presentation, I was able to relax and watch the other presentations. Mark McGuire, Campbell & Paris looked at his workflow and decided on putting engineers in Australia, South Africa and USA to enable 24-hour working. Having his engineers spread out with eight-hour time zone differences meant deadlines could be met and timelines shortened.

Brad Adams of Woolpert reinvented the wheel – adding them onto his tripods to knock minutes off the scanning workflow and also having the added benefit or avoiding alligators by scanning with Asus tablets and operating the scanner remotely. On a more serious note, he stressed that he has seen benefits in quality and programme by using Leica Geosystems TruView and hyperlinks in AutoCAD to raise the bar on communication – nipping problems in the bud before they proliferate.

A great example of scan to BIM was detailed, creating Revit models of the Atlanta state Federal building: 432 HDS C10 scans, 15,000,000 points – rooftops, facades and walkways, saving hours by shaving minutes off each scan. Getting an efficient workflow can make or break a project and enable saving for clients and profits for users.

Mike Stroud of Straub Surveying bought a scanner last year and started scanning 400-foot-tall offices in downtown Cleveland. Using the scan data to analyse verticality of building faces and quality assure floor slabs, looking at fine deviations

Last up was Craig Fries, CEO of Precision Simulations Inc., talking on Forensics and using scan data to create a definitive data set, document physical evidence and reconstruct incident scenes, attaining a 100% admissibility record to get 3D data into the courtroom and prevent the evidence. The presentation included some very high quality animations based on physical evidence, scan data and reconstruction – all measurement, not conjecture, being backed up by knowledge of the potential errors. Larry from the IAFSM, the International Association of Forensic & Scientific Metrology (http://www.iafsm.org/), stressed that Leica Geosystems was also willing and able to act as an expert witness in support of a recent case, critical for getting laser scanning data accepted into court.

Overall, there were some great presentations today – all using HDS techniques and equipment to attain:

Higher speed

More detail

Better reliability

Improved communication

Lower costs

Shorter time

Fewer errors

Faster decision making

Agile workflows

For those deciding to get into 3D laser scanning, if you watched these presentations, it’s a “no brainer!”
