Sažetak
The actual object movements can be examined by well designed and carefully performed observations and measurements. The processed and adjusted data are a precondition for analysis and interpretations of short and long-term predictions of object functionality. Beside periodic deformation observations, experimental measurements could be performed on selected objects. The purpose of such work is to determine the accuracy and improve the applied methods of measurement based on the analysis of theoretical errors and actual values of the facility shifts on a daily basis. On the business tower "Zagrepčanka" the GNSS measurements in relation to the nearest reference station from CROPOS (Croatian Positioning System) network were performed, combined with geometric levelling and gravity measurements. Analysis of measurement results that are presented in this paper provides an answer to the question to what extent one method can be controlled by another, or to what extent the application of a combination of different surveying methods affects the quality of the interpretation of the results.
