The basic concept of this final paper is the project of organizing the construction of the sports hall of the 6th elementary school in Varaždin. In this paper I have developed a plan and technology for the execution of works, calculations and a timetable for the execution. The analysis of the organization of the construction I made on the basis of the main project obtained from the contractor of the Hidroing company in Varaždin. The technical description of the hall is followed by the construction work technology, which describes in detail and specifies how the works are performed and with which machines. Also for added visualization some pictures are added. Further, I have analyzed in detail the construction site scheme, obtained by the company. The calculations or the analysis of prices that I have made through the books of standards, which are presented in this paper in a table, make an important part. I also calculated the duration of each activity by date, and finally received the total period required for the building to be built. I used the Microsoft Project software tool when creating the Gantt chart. The estimated cost is 4.679.022,92 kn, while the total required duration will be 298 days. The necessary input data used in the preparation of this work were collected from the project documentation of the contractor, professional literature, the Internet, notes from the course Organization of Construction, bids and prices from suppliers of building materials and other materials and equipment required for this construction. In this paper of organization construction is finally analyzed: the technical description and purpose of the facility, the technology of construction works, the calculation and analysis of unit prices, the scheme of the construction site and the timetable for the execution of works.
