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 " CBSCI" 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.
