Libya Petrol Endüstrisinde Gerçekleştirilen İnşaat Projelerinde Gecikme Nedenleri ve Sonuçlarının Analizi

Bir projenin performansı genelde üç boyutta ölçülür: süre, bütçe ve kalite. Bu üç boyut birbirinden bağımsız olmadığı için, genellikle projede bir gecikme aynı zamanda bütçenin aşılmasını ve kalite problemlerini de birlikte getirir. Bu nedenle gecikmeye neden olan faktörlerin projeye başlanmadan önce belirlenmesi son derece önemlidir. Bu araştırmanın amacı, güvenlik, düzensiz piyasa ve kırılgan hukuk sistemi gibi zorluklarla yüzleşen Libya petrol endüstrisinde gerçekleştirilen inşaat projelerinin gecikme neden ve sonuçlarını değerlendirmektir. Bu amaçla Libyada petrol sektöründeki aktif proje sahipleri, yükleniciler ve danışmanlar ile bir anket çalışması yapılmıştır. Anket sonuçlarına göre en önemli üç gecikme faktörü; güvenlik faktörü, malzeme/ham madde yetersizliği ve kullanılan inşaa metodu olarak tespit edilmiştir. Bunun yanında gecikmelerin sebeb olduğu sonuçlar, maliyet artışları, süre aşımları, ihtilaf, projeden çekilme ve hakeme başvurma şeklinde sıralanmaktadır

An Analysis of causes and effects of delays in construction projects in Libyan oil industry

Performance of a project is usually measured in three dimensions: time, budget, and quality. Since these parameters are interdependent, delay often means also budget overrun and quality problem. Hence, identification of delay factors before execution of project is of paramount importance. The purpose of this research is to assess causes and effects of delays in construction projects conducted in Libyan oil industry where security issues, deregulated market, vulnerable legal framework are challenges waiting in front of construction sector in the country. To identify the most essential factors, a survey is conducted among clients, consultants and contractors involved in projects in Libya. Findings reveal that the top three delay factors are: security factor, shortage in material, andconstruction method. On the other hand, cost overrun, time overrun, disputes, total abandonment, and arbitration are the main effects of delays.
