Vermessung AVT-GmbH has been active in the Allgäu region for more than 10 years and emerged from the surveying office Martin Köhler, respectively Geosigma GmbH.

As part of the AVT Group, we have over 50 years of experience in engineering geodesy!

In addition to alpine operations, our tasks also include road construction, housing and industrial construction projects. For monitoring measurements accurate to the millimeter, our entire know-how is used to always be able to provide reliable data. Depending on the purpose, we always use the most optimal technical equipment....

For the evaluation of the survey data, the most modern software packages of the companies BriscCAD or IDC EDV are available in the office. With these program packages, as-built plans, deformation evaluations, 3D models, DTM calculations, rental area determinations or construction settlements can be processed competently and in high quality.

We are your reliable partner

Ownership of land is characterized by high security of value.

To ensure that everything is geometrically correct before, during and after construction, we accompany your construction project from project to completion and assure you of accurate and timely completion of surveying tasks for all project phases.

The changeover of the official reference system in Bavaria to UTM32 on January 1, 2019 presents new challenges for all parties involved. For example, distances and areas calculated from UTM coordinates deviate from the real measurements (=natural dimensions). In Bavaria, this can amount to a difference of up to 12cm per 100 m of measured distance!
This is to be considered with exact planning / border distances etc. in any case!

We will be happy to work out a solution for your project that has been coordinated with all parties involved.

Due to the registration in the list of "Prüfsachverständige für Vermessung im Bauwesen" of the Bavarian Chamber of Engineers (Bau), Dipl.-Ing. (FH) Martin Köhler is also able to carry out control tasks of the lower building authority or to survey the new building also for the transfer into the digital cadastral map.
