About the Surveying Bureau
The Gantzert Surveying Bureau is a publicly commissioned surveying office (ÖbVI) founded in 2007, located in Groß-Bieberau at the gateway to the Odenwald. The owner, Dipl.-Ing. Markus Gantzert, is authorized as an organ of the public surveying service for official real estate surveys and also offers engineering surveys. The scope of services includes real estate surveying (dismantling/division surveys, boundary determination, building surveying, construction site planning), technical surveys for planning, construction execution, and monitoring (setting out, elevation and inventory plans, volume calculation, billing plans according to REB, utility cadastres, industrial surveying, settlement and deformation measurements, GIS), as well as airborne surveying using UAV drones including photogrammetry, point clouds, and orthophotos. Customers include the construction industry, municipalities, industry, and private landowners; the service area ranges from the Rhine-Main area and Odenwald and beyond.
