Sažetak
This paper analyses the problem of quantifying the significant risk factor influence on contracted construction time extension by applying the mathematical method of multivariant regression analysis. It can be said that the Bromilow „time-cost“ model significantly simplifies the problem, even to the extent which sometimes can not be considered as satisfying because it does not take into consideration the number of circumstances which lead to the event realization in the specific way. Under series of circumstances which lead to the specific event occurence those that are of the greatest significance must be proven in the exact way. The appropriate mathematical procedure is the multivariant regression analysis. Its application enables the detection of the joint influence of several independent variables on the observed dependent one (the construction time overrun) in which process the number of measurements is considerably larger than the number of variables in question. This paper analyses 28 hydraulic engineering structures (water supply structures) in the context of modeling the significant risk factor influence on the construction time overrun. By applying the SPSS9 software the regression equation is to be obtained and the joint influence of risks on construction time overrun is then defined. However, it must be pointed out that the obtained equation is applicable to the research area only because the risk factors are specific in natural, economic and other circumstances for each research area.
