The construction project includes all the activities of conceiving, defining and executing the constructjon and commissioning of a building that meets the needs of the client. Planning is a procedure in which the events and activities of future processes are predicted, and then, based on known data and background documents, as well as set technology and work organization, their connection, dimensioning, and scheduling are carried out. The thesis analyzed the literature related to work execution plans, mostly describing state-of-the-art of construction planning. Also, Croatian construction regulations related to the work execution plan were analyzed, After that, a case study was carried out describing the approach to creation of the execution plan for the project of reconstruction of the public building, the palacin student dormitory. Finally, a comparison of the practical approach from the case study with the best practices described in the literature was made. The conclusion is that the regulations are respected, but also that the state-of-the-at practices in planning are more detailed and of better quality than what is done in Croatian practice, and that there is room for improvement when creating execution plans.
