We then took two final shots on the inside of the 84-inch diameter pipe and we had what we felt was everything we needed.” In total, for the exterior of the structure, we did six different setups. “Then we set up the GLS-2000 and started the scanning session.
“We built the structure using existing control points and localization that ties us into state plane coordinates,” he says. Capable of capturing point cloud data at a rate of up to 120,000 points per second at a distance up to 350 m (varied and user-selectable), and offering a simple one-touch operation, the instrument did not disappoint, according to Wise. The solution to which Wise refers, a Topcon GLS-2000 compact high-speed 3D laser scanner, offers them a wealth of benefits which he feels will make many parts of their job faster, safer and more cost-effective.

“The big plus for us, is that we now have more than five million points to look at from any given angle and from which to gather info - not just today or next year but long down the road.” That’s the first time we’ve ever faced that, but I sense it won't be the last the technology and the solution it provides are making huge inroads.” “That project, the massive South Florida Water Management District’s C-44 canal near Lake Okeechobee, came with a prerequisite that, to even bid on the job, a company must either have a scanning capability or subcontract to a firm that did. “For a different job we will be starting not far from here, we had recently purchased a Topcon GLS-2000 laser scanner,” he says. Wise knew there had to be a better way and suspected that the solution they needed was already in their inventory, it just hadn’t been tried yet. From that info, we would have to interpret all the data that lies in between those few shots. In the past, once we were at a point where we needed an as-built, we would call in surveyors and they would take a shot on each corner and a shot on the invert of the pipe, that was it. “It was on one of those that we decided to go a step further than we normally do in generating our as-builts. “Our part of the overall project for the FWMA includes the construction of 12.5 miles of levee, and within that levee, we are building several structures that allow water to pass through in a controlled manner,” he says.

According to Jay Wise, manager of BGC’s GPS and technical department, they’ve been involved in a series of projects in that area since about 2008 but this latest component is a bit of a departure. John’s River Basin Project, including one called the Fellsmere Water Management Area (FWMA) located about 25 miles west of Vero Beach, Florida. When complete, the FWMA will add an additional 10,000 acres of restored wetlands to the headwaters of the St. Because of both its south-central Florida location and excellent reputation, BGC has been successful at landing a series of projects associated with the Upper St.
