Smart Targets, Datums & Reflectors

Available from Berntsen International Inc

Berntsen International, Inc., is the first United States source for Rothbucher Systeme’s full line of permanent precision survey markers. Designed to facilitate precise building, site layout, and monitoring, all Rothbucher survey markers and control points are made of tough, UV resistant materials and are intended for discreet, long term, highly precise control monumentation.

The Rothbucher System includes 20 specialized markers for placement on buildings, bridges, towers, roads, railroad tracks, and anywhere else precise, repeatable control is needed. Rothbucher markers typically include a reflective surface for use with most total stations, and a bull’s eye or level line (or ledge) for accurate targeting. When placed on building axes or other critical dimensions, Rothbucher control markers can be used by most of the trades associated with large construction projects. They can be attached to important reference points by adhesive, threaded inserts, or can be set directly into concrete. One set of markers can be attached to formwork, and leaves a negative impression in concrete that can then be used for an elevation reference during the life of the entire project. Another set has a built-in ‘roof’ that protects the target from any concrete applied to the structure after control has been placed.
