Summary:In road construction, construction machines are used for levelling and adjusting the earth's surface. These modern construction machines use a 3D GNSS levelling system to achieve the projected shape and elevation of terrain with the required accuracy within permitted setting-out deviations according to the project. In the area of interest were realized geodetic check measurements. The aim was to objectively assess and evaluate the practical applicability of connection between a construction machine and precise surveying instrument for determination of position and height in real time. Check measurements were based on the same reference points as were used for the construction machine in surface adjustment. The surveying instrument used for check measurements provided surveying results of required accuracy. Subsequently, the obtained data were used to compare the projected and the realized state. Height deviations of check points and deviations of the cubic content of laid material of individual sections were defined.
