Abstract

The paper presents a procedure to estimate benchmark’s stability by adjustment of free geodetic elevation base network. The  changes of adjusted heigh by software “ CBSC1” for free networks consisted 3,4,5 benchmarks  are 0.1-0.2 mm  when to compare this method with a method one benchmark is unchanged in height  and  method the mean of heigh for benchmark group is unchanged . So, we can use this method for estimation of benchmark’s stability when to measure settlement for engineering constructions.
