Construction process supervision risk management |
Sekundarni povzetek: |
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. |

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. |
