This paper deals with the problem of positioning a tower crane and facilities on construction site for masonry works. The introductory part describes the problem of positioning the tower crane and facilities on the construction site and defines the purpose of this paper. In the second chapter there is a brief overview of the literature dealing with the optimization of the tower crane location and the authors' approaches are explained with a brief overview of the extent to which the field has been reached. The third chapter presents a mathematical model for optimization problem. All the necessary equations for modeling and solving optimization problem have been set up, a objective function is specified and model constraints are set. Also, the assumptions that were introduced in the model were explained in order to facilitate the approach to solving. In the fourth chapter, the mathematical model was applied on the practical example of a residential building in Osijek. All input parameters for solving optimization problem have been written, modeling is explained and then an algorithm is chosen to solve this problem. In the fifth chapter, the obtained results were analyzed. It is explained what are the advantages, but also the weakness, of the presented optimization model and also the considerations for further development of the model. The results showed that this method has the potential to make significant savings of main resources - time and money.
