The correct determination of displacements, mainly vertical ones, of the buildings and other building objects is necessary for the statement of changes in construction of these buildings and working out the security rules and forms, allowing for the avoidance of the building catastrophes. The geodetic vertical displacement measurements ought to be performed with high accuracy. For that reason, the most appropriate method of their determination is the precise geometric leveling. This method is characterized by not very long time of realization, but on the other hand there are some inconveniences, caused by doing works in unfavorable terrain conditions (road, vehicular and pedestrian traffic, variable lighting conditions). As a consequence, it is advisable to use for displacement measurements the measurement equipment of high precision parameters, preferably with the automatic registration of the measured elements. In this work there are presented the outcomes of the vertical displacement measurements for the five annual cycles of the Wroclaw University of Environmental and Life Science’s buildings, situated in the area of Grunwaldzki Square. The measurements have been carried out between the years 2006-2010. Because of the statement of abundant cracks of the walls of these buildings, the terrain works have been carried out there. Taking into consideration the localization of the cracks in the area of the ice-marginal valley of the Oder River and their time formation, there has been assumed, that the floods in years 1997 and 2010 are the main reason for the cracks occurrence as well as earthworks associated with doing deep, wide-spatial pits of new building objects . The terrain measurements are performed mainly by third-year students of land surveying in frame of the terrain classes within the Engineering Geodesy course. The terrain data for computations have been prepared by students in frame of their master's thesis works under the authors' of this paper guidance.
