The purpose of this paper is to approximate the procedure for obtaining a building permit. Namely, in this process in which we participate as designers, clerks, auditors, investors, etc., there is a certain order that we must follow in order to achieve maximum efficiency and economy. It is our duty to act in the interest of the investor when obtaining a building permit and to advise him in which direction to go. We must acquaint him with his rights and obligations and try to fit his wishes into the framework of the law. We need to pay attention to details that can speed things up. We can speed up certain parts of the design by keeping in mind the steps that follow and obtaining the necessary documentation in the initial stages of design. This will not only save much needed time but will also further insure against difficulties that could be caused by a factor that we did not pay attention to when starting the design. It is important to note that due to changes in the Construction Act, which states that the Geodetic Project is an integral part of the Main Project, one should carefully select the office that will lead the entire process of obtaining a building permit. It is best to hire an office that has all the necessary authorized persons (surveyor, architect, mechanic and statician). It is possible that such an office will not be able to start the project immediately but will stick to the agreed timeframes. It is also possible to hire each individual authorized designer/technician from several smaller offices, but the obstacle is the coordination between offices. When designing, all available technology should be used, which will facilitate the process of designing and obtaining a building permit. E.g., “eDozvola” is a transparent platform for submitting the necessary documentation and for issuing all necessary permits for access to construction. With the help of the platform, we can request the issuance of special conditions and connection conditions for the construction in question, issuance of location permit, issuance of building permit, etc. We can at any time see the status of the submitted object through the platform and quickly complete / submit the necessary documents. „Informacijski sustav prostornog uređenja“ (ISPU) with the help of location information obtained from investors can bring us closer to the spatial plan in force, show whether the plot is in the desired class for construction, whether a plan is planned in the interest of the municipality, etc. It is useful a tool that can approximate the framework in which it can be built (indicate what kind of terrain it is) and which refers to the legal acts to which we must pay attention. Depending on the level of the authorized user, you can see the issued permits on a particular plot, report irregularities or illegal construction, see contracts for the sale of real estate, issued energy certificates, etc. There are various programs that started with the BIM way of displaying an object. BIM stands for Building information modeling. With these tools we can get an insight into the 3D appearance and the amount of material needed to build the object. The advantage of this program is that it provides insight into possible problems in the design phase and more detailed preparation for them. With the help of this technology, it is possible to elaborate the course of construction in more detail and make a more accurate Gantt chart of obtaining the necessary documentation of the building. In this paper, I will describe the process of using these platforms and their advantages. Of course, all these platforms are not complete and, in some cases, it is necessary to check the information read from them. It should be noted that these platforms are becoming more and more harmonized every day and are becoming a very useful tool in obtaining various permits.
