Identifying the Risk Impact on Cost and Time of the Egyptian Non-Residential Buildings Projects

Abstract

Construction projects in Egypt were typically influenced by multiple risk factors which have various impacts on both cost and time objectives that lead to project cost overruns and time delays. This paper presents the results of an investigation study concerns with the identification and assessment of risks associated with the Egyptian Non-Residential Buildings Projects (ENRBP). The study explores risk factors probability of occurrence and their effects on cost and time of these projects. A field survey was conducted with professionals in the construction projects in EGYPT for a purpose of collecting the required data of the risk factors characteristics. Based on results analysis, several risk factors were identified and categorized into fifteen risk groups as well as they were prioritized based on their effects on cost and time. A high agreement for ranking risk factors among contractors, consultants and owners was acquired. The list of the major risks included many factors such as: dramatic changes in the materials prices and Adopting direct attribution system rather than tendering and bidding systems. The most expected average increase of the cost overruns and time delays was more than 20% of the project planned budget and schedule. Finally, the analysis and findings showed that risk factors were very close in their impacts on both cost and time of ENRBP.
