In paper are presented results of bioclimatic model Wet bulbe globe temperature (WBGT) for the area ofthe city of Bijeljina, for the period of 10 years, from 2009 to 2018. The city is located in the north eastpart of Bosnia and Herzegovina and has a moderate continental climate. Results were obtained bycalculation of meteorological data in software program Biklima 2.6. They show the presence of all fivevalues defined with the WBGT index. Results differ in during the year, and seasons and have differentnumber of days with the Unlimited (<18) being the most common value and Activity should be stopped(>30) the least presence. Some years have the high number of high values (over 30) and present apotential danger for a human organism if exposed to physical activities. Number of consecutive days withhigh value rises and presents danger for human organism.
Before joining the European Union, Serbia faces a big task related to the treatment and purification of wastewater. The capital of Serbia, Belgrade, and some larger cities do not have wastewater treatment plants. Although there are no plants in larger cities in Serbia, they still exist on the territory of the state itself. However, either they are not in good condition, or they do not work with the projected capacity or they do not work at all. This paper presents the model for risks quantification for the planning and design processes of wastewater treatment plants in which the risks are divided into 6 categories: legal, financial and economic, logistics, environmental protection, management and design risks. 37 risks have been defined, analyzed and evaluated by the experts participating in the Delphi method. Experts in various fields dealing with the planning, design or construction of wastewater treatment plants were selected to assess the risks through 2 rounds of Delphi methods and reach the consensus on major risks. By using statistical methods, it is determined that the experts reached the consensus after which each risk received its own relative weighting coefficient. Risk model has been initially verified by experts from Delphi team on two projects during construction phase. This model is important in the initial phases of the project, when the investor starts the project, as well as in the design phases.
The construction of plants for desulphurization fluegases at The Thermal power plant Ugljevik 1, is planned within modernizations The Thermal power plant in according with enviromental rules. The plant is constructed of more objects, which will be founded directly with existin object of The Powerhouse. The complexity of geological terrain construction and the selectio of optimal parameters for objects foundation. The conducted researchs are in according with The Eurocod 7 rules, but the budget have been differently carried, for shallow and deep foundations. The shallow foundations is in according with The Code of practice technical norms for building construction foundations, but the deep foundations are in according with The Eurocod 7. There is a common choice of parameters for the separated geotechnical enviroments and their setting in appropriate models. The obtained values are the base for the development geotechnical projects for the foundation of plant facilities.
In this work one example of civil engineering research conducted with the Delphi method is shown. The Delphi method is one of the most popular scientific methods for research of problems with lack of known data. For this research, researcher must form the team of experts and analyze their answers on questions asked during the research with controlled feedback. In this article researcher wanted to prove hypothesis for making risk assessment model for planning and design processes of wastewater treatment plants. This research was conducted with Classical Delphi method is shown step by step.
