The basis for this graduation thesis was a finished project documentation for a complete reconstruction of an apartment building in Trnovo. The reconstruction includes an energy and anti seismic renovation of the building, the construction of a new garage, the construction of habitable spaces in the basement and the attic, as well as a comprehensive reconstruction of the yard with a construction of a new steel terrace and a new entrance into the building. In this thesis, I present my idea for the organisation of the construction site, the execution method of construction works and a suggestion for a time plan of the execution of a renovation project of a family house on Finžgarjeva street. Due to the size of the renovation, only those works that require more engineering and organisational knowledge are described in detail from an execution point of view. Other works are only briefly presented and described. In addition to this, the graduation thesis also includes a description of the current state of the building and the garage, based on a personal visual tour with a detailed list of insufficiencies and damages. In a separate chapter, a future state of the building is also presented. Due to an inadequate survey of the project documentation that did not include all of the phases of the reconstruction and calculation of costs of the investment, I prepared a revised survey of works with a correct cost calculation of the renovation investment.
