The precision levelling and the associated measuring equipment must be adapted to the accuracy requirements (1st order, standard deviation SS for one kilometre double levelling ≤ 0.4 mm/km, permissible distance contradiction: ZS=0.5*S+-1.5*SQRT(S) taking into account local conditions. At least two measurement teams must be deployed daily for the levelling. In addition, a reserve measurement team must still be available for leveling.
For height transmission with large and different target distances, classic current transition levels must also be observed. Corresponding special equipment from Zeiss can be provided free of charge by the Federal Institute of Hydrology (BfG).
There is no marketing work. The further processing of the levelling data as well as the calculation of the final heights is carried out by the client.
Measurement sketches, some photo sketches and point lists will only be provided after commissioning.
Please refer to the tender documents for a detailed description of the services to be provided.
