Introduction d’une nouvelle dimension dans la capture de la réalité et redéfinition de la numérisation laser 3D.
Leica TS20 and AP20 AutoPole bring accuracy and efficiency to a challenging bridge construction project.
My name is Joni Tenhunen, and I work as a Survey Manager at MittausGroup. We are currently working on the Junatie metro bridge project, where an old metro bridge is being demolished and replaced with a new one. It is a major project that will take more than two years to complete.
I have used Leica Geosystems surveying equipment for most of my career. At times, I have also worked with solutions from other manufacturers. However, for the past six years, Leica equipment has been my primary choice.
Our company uses several Leica Nova MS60 MultiStations and TS16 total stations, as well as the RTC360 laser scanner. Our latest investment is the Leica TS20 robotic total station.
We have been using the TS20 since the beginning of June, and our first impressions have been extremely positive. The instrument feels lightweight, accurate, and easy to use. It works particularly well with the Leica AP20 AutoPole.
Setting up the pole is quick, and the measurement accuracy has been impressive. We often check measurement results against previously marked points, and even with a long pole, we typically achieve accuracy within approximately 5 mm.
The greatest benefits of the TS20 and AP20 combination are especially apparent in complex construction projects and in confined or difficult measurement environments.
For example, I have used the system when measuring a waterfront retaining wall, where taking measurements between reinforcing bars would have been much more difficult using traditional methods. The AP20 also makes work easier in environments with numerous obstacles.
On a project like this, there is a lot of traffic, along with poles, vehicles, and other line-of-sight obstructions. Thanks to the tilt capabilities of the AP20, the survey pole does not have to remain perfectly vertical at all times, which speeds up the work and makes surveying more flexible.
I can highly recommend the Leica TS20 total station, particularly for concrete construction projects. One of its strongest features is its highly effective surface measurement capability, an area where Leica instruments have traditionally excelled.
In addition, prism tracking works reliably, making day-to-day field work easier. Overall, the Leica TS20 has proven to be an accurate, efficient, and modern surveying instrument that meets the demands of challenging construction sites.
