In 1996 Georg Rothbucher was visiting a customer at a construction site who was facing a difficult problem. Two thousand square meters of concrete had been poured incorrectly for the Finished Floor Level (FFL) of a new building. This surveyor was trying to recover the original reference point used to set the FFL – a chalk mark, pencil line or a nail.

Through it all, Berntsen is right beside surveyors, providing trusted, innovative products – including our Rothbucher line. These products are designed to streamline surveyor’s work by ensuring that all measuring points represent clear, permanent, and unmistakable records – for boundaries, monitoring, construction, mining, roads, rail lines and more.
