Preliminary risk assessment model of wastewater treatment plant construction

Abstract

Predmet ovog istraživanja je formiranje modela preliminarne procjene rizika za proces građenja postrojenja za prečišćavanje otpadnih voda (u daljem tekstu PPOV). To podrazumijeva identifikaciju, analizu i evaluaciju, tj procjenu i ocjenu značaja pojedinih rizika građenja PPOV. Na osnovu dobijenih podataka formira se model preliminarne procjene rizika za proces građenja. Da bi se došlo do neophodnih podataka za formiranje modela koristi se Delfi metoda (metoda ekspertske ocjene).  Eksperti predstavljaju tim formiran od grupe eminentnih stručnjaka iz različitih oblasti značajnih za izgradnju objekata za prečišćavanja otpadnih voda. Ovi stručnjaci su birani na osnovu definisanih kriterijuma i klasifikovani kao eksperti. Eksperti u Delfi metodi treba da postignu konsenzus i nakon toga je potrebno verifikovati predloženi model prelimarne procjene rizika za proces građenja PPOV. Takav verifikovani model može da se uvrsti u procedure upravljanja rizicima u okviru upravljanja projektima izgradnje PPOV.The subject of this research is proposing of a new model of preliminary risk assessment of wastewater treatment plants construction (hereinafter WWTP). This implies identification, analysis and evaluation, ie. assessing and evaluating the importance of the risks during construction of WWTP. Based on the data obtained, a model of preliminary risk assessment for construction is formed. In order to get the necessary data to form a model, the Delphi method is used (the method of expert assessment).  Expert team is formed as a group of eminent experts from different fields important for the construction of wastewater treatment facilities. These experts were elected based on defined criteria and classified as experts. Experts in the Delphi method should reach a consensus and after that it is necessary to verify the model of proposed preliminary risk assessment of WWTP construction. Such a verified model can be included in risk management procedures as part of the management of WWTP construction projects
