By his own admission, Roger Croft is not easily impressed with most of the new machine-control products that come out for today's construction professional. The veteran sales technician from equipment supplier Lengemann of Florida says he has seen products come a¡d go, and often the end result falls far short of the promises made by the manufacturers. In recent years, however. he has seen such products become increasingly sophisticated-better able to cope with and adapt to changing site conditions.
Olin Ellsworth may be “twenty-something,” but he still considers himself “old-school” when it comes to construction work.
So when the heavy construction manager for Ronald Franks Construction of Savannah, TN, initially considered how he might successfully land the Reedy Creek Dam project, his first thought was a conventional, total station approach.
"You're not going to believe it!"
Murray Lodge, vice president of construction for Topcon Positioning Systems (TPS), is talking about the job site results of Topcon's 3D-MC² system and reporting productivity gains more than twice that of regular 3D machine control systems.
When the Utah Department of Transportation (UDOT) set out to rebuild Interstate 15 south of Salt Lake City, the department needed accurate one-foot contour interval mapping and a digital terrain model (DTM). With accurate maps and models of the 20-mile stretch of freeway, designers could calculate precise earthmoving quantities. Those in turn would lower UDOT's risk of disputes over actual earth moved.
A principios de este año John Deere y Topcon Positioning Systems sorprendieron al mercado mundial de equipos de construcción con una máquina excavadora que realiza trabajos de nivelación y excavación a una velocidad sorprendente. El equipo tenía un accesorio especial: el sistema de control más rápido del mercado, el 3D-MC² de Topcon Positioning Systems.
The most commonly cited benefits of Global Navigation Satellite System (GNSS)- enabled machine control are grading and excavation productivity and the cost savings that result from a reduction in manual tasks such as excavation depth verification using conventional surveying methods. The use of this technology on recent underground utility work for a state vehicle maintenance facility outside of Phoenix, AZ, demonstrates that it has something in common with the Construction Management at Risk (CM at Risk) project delivery method, in which cost control is a major priority.
Accuracy improvements and cost reductions in the surveying field have both accelerated rapidly in recent years, driven by changes in work procedures that combine different instruments and techniques. Sensor integration for positioning and precise navigation is the principal innovation responsible for these advances.
"Companies embracing increased productivity through technology will drive the world's economic recovery."
President and CEO of Topcon Positioning Systems Ray O'Connor, said the statement above is what drives top-ranked technology companies to continue to support strong research and product development efforts.
