TECHNOLOGY TOOLBOX iCON Robotic Station Cuts Manpower Needs in Half BY DEBRA WOOD FASTER, MORE ACCURATE LAYOUTS ARE POSSIBLE with robotic total stations designed for the construction industry. The iCON robotic total station, from Leica Geosystems with its U.S. headquarters in Norcross, Ga., allows a single operator to complete construction layouts and asbuild checks. Gary Frame, job superintendent at T.U. Parks Construction Co. of Chattanooga, Tenn., an AGC of East Tennessee member, is using the Leica system at a 190,000-square-foot remodel and new construction project for Memorial Hospital’s Glenwood Campus South in Chattanooga. “It eliminates a man and makes things progress more quickly,” Frame says. “It saves money. You have a man making $30,000, and you can do away with that man and save $30,000.” The iCR50 robotic total station allows one-man layouts. The iCR50 robotic total station is part of Leica’s iCON suite of intelligent construction and machine control hardware, including GPS antennas and data collectors, and software. The portfolio works seamlessly with all of the other iCON products. “The same software on one of the new data collectors will control a mechanical or a robotic total station, as well as the new iCG60 GPS antenna,” says Carl Singleton, Leica product manager for the building segment. The iCON software wirelessly passes information from the field to the office or from instrument to instrument. Contractors fi nd surveying with an iCON total system easy, because workflows, vocabulary and data needs are set for construction not professional surveying fi rms, says Pat Smith, building and construction segment business manager for Leica Geosystems. Greater use of building information modeling has increased the use of robotic total stations, says Smith. Contractors are able to download an architect’s or an engineer’s design to the data collector, a handheld tablet computer that communicates with the total station and can be used to begin staking out the required points. “The drawings are put on a tablet and [the operator] can pull up the drawings and have a better feel for what he’s doing,” Frame says. Contractors often use the system for placing the building on the property, and identifying the location of steel in the foundation, anchor bolts for columns and other elements. They can choose points or lines directly from a map, without entering numbers or scrolling through lists. Frame says that having only one man responsible for the layout “cuts down on mistakes. That one guy can trust what he is doing.” The contractor levels the instrument and takes a couple of basic orientation T.U. Parks crew members onsite with the iCON robotic station. shots, working off reference or control points established onsite. Smith added that the instrument will know where it is on the jobsite. “Once you know where you are relative to the design, you can do anything on the job you want, in terms of putting in grade stakes or stakes for excavation,” says Smith. The robotic station will follow the person with the prism pole around the jobsite. Smith estimates one person using the robotic system can layout 400 to 600 points per day in a commercial building compared with 200 per day with conventional tools. With integrated tolerance checks, the accuracy of all those points laid out improves as well, Singleton says. “It’s a powerful instrument,” Smith admits. “And we’ve made it easy for contractors to work with.” The iCON robotic total station with data collector costs about $30,000. Manual total station packages begin at less than $10,000. But additional costs for the robotic system can be recouped, Smith says, with increased productivity. “Doing away with a man, using robotics and carrying the drawings on the table with you is a big deal,” Frame admits.
