A leader in laser scanning applications on projects around the globe, Langan Engineering & Environmental Services recently purchased the new, advanced Leica ScanStation P20 for the scanner’s data acquisition speed and accuracy.
Joseph Romano, PLS, vice president of Surveying & Mapping at Langan Engineering & Environmental Services, says, "As surveyors, we preach accuracy above all things—and we all know that we cannot make data any smarter or more accurate than the first time it’s gathered. Leica Geosystems has a long standing reputation for delivering highly accurate survey grade instrumentation. The Leica P20 is no exception. With it, we get more data, faster and with great accuracy."
The Leica ScanStation P20 is one of the most accurate scanners Leica Geosystems has developed to-date, offering 3 mm precision at 50 meters and 6 mm precision at 100 meters with a combination of highly accurate, low-noise angular and range measurements. Built on an innovative combination of time-of-flight range measurement and modern Waveform Digitizing (WFD) technologies, the scanner can achieve 1 million points per second scan speed plus sub-millimeter range noise at its maximum range of 120 meters.
Romano adds, “Versatility is an added bonus of the Leica P20. Our client base is global, so we need the ability to transport survey equipment easily and then operate in wider range of conditions including harsh, inaccessible or unsafe areas. It’s so important to collect as much data with as much accuracy as possible in any given situation.”
Designed to master demanding environments, the Leica ScanStation P20 is able to operate at temperatures from -20ºC to +50ºC, and with IP54 protection. The Leica ScanStation P20 is also the industry’s first laser scanner to include an onboard Check & Adjust routine, which allows users to perform electronic instrument field checks and adjustments.
“The Check & Adjust routine is an especially welcome addition,” says Romano. “We regularly send units out for adjustments and cleaning annually, which takes them out of the hands of our survey teams. Now, we have the ability to do checks, adjustments and calibrations of the Leica P20 in the field, keeping the scanner at the ready for any opportunity. Through our extensive experience with laser scanners, we’ve learned that the applications of scanning data are limited only by our surveyors’ and our customers’ imaginations. The Leica P20 will open up even more opportunities.”
Romano expects to keep the new scanner busy on a range of projects beginning in early 2013. Langan owns four other scanners that include the Leica ScanStation, Leica ScanStation 2, the Leica HDS6000 and the Leica ScanStation C10, which have been used on projects such as St. Patrick’s Cathedral, Madison Square Garden and the U.S. Court of Appeals of the Armed Forces. At any given time, all four of the scanners are in operation on various projects, from large infrastructure surveys to building information modeling (BIM) for existing conditions to documentation of a historic structure; sometimes Langan has even had to rent scanners to meet project deadlines. Joseph Romano is a member of the U.S. Institute of Building Documentation’s Leadership Team, a group focused on developing standards, guidelines and best practices in data gathering and application.
