If you love construction like I do, then the World of Concrete in Las Vegas, NV is the place to be next week. Standards for the use of 3D laser scanning to measure concrete tolerances are being addressed.
The annual World of Concrete conference, running from January 22-25 will attract 60,000 visitors and 1,600 exhibitors.
I will be making a short presentation on some work that I have been doing for the American Society of Concrete Contractors and the American Concrete Institute involving the use of 3D laser scanning to measure concrete tolerances.
One of the major challenges in using 3D laser scanning is accuracy. The tolerances for concrete floor slab flatness and levelness in the booming world of constructing fulfillment centers are very tight, like an 1/8″ to 1/4″. That does not leave much room for all of the other elements of the error budget, nor does it take into account the issue of having the survey control be an order of magnitude better than the laser scanner survey.
