Otoyol projeleri büyük yatırım projeleri olup birçok risk faktörünü içerisinde barındırmaktadır. Bu risk faktörlerinin kapsamlı bir risk yönetimi stratejisi ile yönetilmesiyle proje başarısını etkileyebilecek olumsuzlukların azaltılması mümkündür. Bu çalışmada otoyol projelerinde karşılaşılan risk faktörlerinin önem derecelerinin belirlenmesi amaçlanmıştır. Otoyol projelerinin sözleşme, tasarım ve yapımında karşılaşılan risk faktörleri literatür taraması yapılarak belirlenmiştir. Belirlenen risk faktörleri riskin kaynağına göre 7 ana başlıkta sınıflandırılarak ilgili risk faktörünün otoyol projesinin hangi aşamasında hangi alt risklerle ortaya çıktığı araştırılmıştır. Risk faktörleri otoyol projelerinde tecrübe sahibi ve konusunda uzman kişilerce anket yöntemi ile değerlendirilip, karar matrisi yöntemi kullanılarak risk analizi yapılıp önem dereceleri belirlenmiştir. Elde edilen sonuçlar ekonomik ve politik riskler başlığı altındaki ekonomik kriz riskinin en önemli risk faktörü olduğunu ortaya koymuştur.

Risk Analysis Application in Highway Projects

Öz

Highway projects are large investment projects and have many risk factors. It is possible to reduce the problems that may affect the success of a project by managing such risk factors through a comprehensive risk management strategy. In this study, it was aimed to determine the significance levels of risk factors faced in highway projects. Risk factors seen in agreement, design and construction stages of highway projects were specified by carrying out a literature review. The specified risk factors were classified under 7 main titles according to the source of risk, and emergence of the relevant risk factor at which stage of the highway project along with which sub-risks was investigated. Risk factors were evaluated by administrating questionnaires to the individuals experienced in highway projects and specialised in their fields. Later on, risk analysis was performed using the decision matrix method and their importance levels were determined. Obtained results suggested that the risk of economic crisis under the title of economic and political risks was the most important risk factor.
