Secondary title: Construction process supervision risk management
Secondary abstract: Management of risks related to the construction project costs, timing, and quality of work carried out is permanent activity in the construction process. In order to manage this complex activity with significant financial inputs and environmental impacts, appropriate risk management is required. The investor, as key participant in the construction process, has to supervise the construction process in order to adequately manage those financially and technically demanding activities. The role of supervision is very complex, but one can identify its key function - reduction of risks, that could lead to the development of a construction project in an inappropriate way, resulting in project performance failure. In order to ensure more systematic and better decision-making process, and improved risk management in the construction process, a comprehensive risk management framework that could be applied for supervision of building construction was analysed. The main intention of my work was development of conceptual framework enabling quantitative analysis in risk identification and management. During the development of such framework a register of risks which should be managed during the construction supervision was drafted. After that a basic analytical framework, which can be used for quantitative management of uncertainty and risks in construction, was developed. During the development of those analytical tools important missing element for the adequate quantitative risk management was identified: there is no available information or register containing the history of identified unforeseen events and their consequences, which is probably the main obstacle that hinders the shift to quantitative risk management. Despite the lack of data a decision-making model was developed with a scope of validation of the approach. It was developed for a complex set of uncertain events. It is based upon the conditional probabilities using Bayes' Theorem. As a practical example of quantitative conditional probability network, taking into consideration evidence-based statistic, a model was set for uncertainty management in concrete placing.

Abstract (ePrints): Obvladovanje tveganj, vezanih na stroške gradnje, časovne okvirje izvajanja projekta in kvaliteto izvedenih del, predstavlja stalnico v procesu graditve objektov. Da bi lahko obvladovali vso to kompleksno dejavnost z velikimi finančnimi vložki in posegi v okolje, je potrebno ustrezno upravljanje s tveganji. Investitor mora kot ključni udeleženec v procesu graditve za izvedbo finančno in tehnično zahtevne dejavnosti vpeljati v proces gradnje nadzor nad izvedbo del. Vloga nadzora je večplastna, poenotimo pa jo lahko v njegovi ključni funkciji – zmanjševanju tveganj, ki bi vodila v neustrezne načine izvajanja projekta. V okviru naloge sem iz potrebe po zagotovitvi bolj sistematičnega in ustreznejšega sprejemanja odločitev ter večje obvladljivosti tveganj pri gradnji objektov analizirala celovit okvir obvladovanja tveganj v procesu graditve, ki jih nadzor obvladuje. Vodilo je bil namen, da se postavijo osnove za pristop h kvantitativni analizi obvladovanja tveganj. V procesu izdelave takšnega celovitega okvira sem pripravila register tveganj z vidika izvajanja dejavnosti gradbenega nadzora in opredelila osnovni analitični okvir, s katerim se lahko kvantitativno obvladuje negotovosti oziroma tveganja pri graditvi objektov. Pri tem se je izkazalo, da je odsotnost podatkov o preteklih (že realiziranih) nepredvidenih dogodkih osnovna ovira, zaradi katere je težko preiti na kvantitativno upravljanje s tveganji. Kljub pomanjkanju teh podatkov sem opredelila model odločanja za kompleksne negotove dogodke v prihodnosti, ki slonijo na teoriji Bayesove pogojne verjetnosti. V nadaljevanju sem za potrebe praktičnega prikaza tega orodja na primeru modela odločanja za obvladovanje negotovosti na področju vgrajevanja betona pokazala, kako bi lahko kvantitativno upravljali s tveganji.
