In complex engineering objects such as dams, bridges, viaducts and other objects, deformations occur on them over time as a result of the external factors and the size of the objects themselves. In order to avoid potential disasters, these objects in certain time periods are supervised for potential deformations. There are a range of different methods of deformation analysis through which displacement of objects is determined. In this research a practical application of the Method of Mihajlovič is applied for determination of horizontal deformations of the “Mantovo” dam with the aim of analyzing the conducted results. In practical implementation two epochs of measurements are used, the first epoch from the year 1978 and the second epoch from the year 2008. From the conducted calculations it is confirmed that this methodology has its disadvantages in determination of the stable points that also affect the determination of the points that are located in the dam itself. This issue is overcome by setting more stable points when developing the network, these points should not be dislocated over time, but of course in natural environments this is difficult to achieve. The inability of determining the stable points is a major drawback that limits the practical implementation of this methodology.
