The diploma thesis is focused on the determining the fees of designers, engineers and technicians in construction engineering. The introduction of the thesis defines the fee, the eligible costs, the fee zones or the budget. In order to determine the fee, historical and current expert publications were presented in detail, according to which the calculation of fees is determined. Based on the publications, these methods were applied to three model examples and then the results were compared. In addition, a short questionnaire is included in the thesis, where asked designers, engineers or technicians present a calculation method or a combination of the methods they use to determine their fees. On the basis of these facts and findings, an overall evaluation of the fees is made.
