Abstract: Delays in Construction Projects are one of the major challenges faced by all Projects Stakeholders. Therefore, it is important to review and analyze the published papers in the leading construction management journals. The objective of this paper is to compare the findings of the published papers based on the causes of delays from different geographical locations. The Severity Index (SI), Relative Important Index (RII), and Spearman rank correlation factor had been used across all these published papers to measure and rank the impact of each causal factor. The findings of this paper intended to provide summarized causes of delays in construction projects which already have been provided. Keywords: Delays; Delays on Construction Projects; Causes of delays in Construction; Severity Index; Relative Important Index.
1. INTRODUCTION Most contractors and owners believe that the delays on construction projects are one of the biggest challenges faced during the project life cycle. All around the world many construction projects face one of the biggest construction problems which is the delay, delays differ from one country to another, from one construction project to another, and from construction type or cost to another due to every project circumstance Sullivan and Harris [20]. Therefore, the aim of this paper is to provide an insight into highlighting the major causes of delays from different geographical locations
2. RESEARCH METHODOLOGY The methodology that has been used in this review paper is based on the use of publicly available digital databases such as Google Scholar. In addition, these papers have to be published in the leading construction management journals such as the International Journal of Project Management (IJPM), Alexandria Engineering Journal (AEJ), Procedia Computer Science (PCS), Malaysian Construction Research Journal (MCRJ), Journal of Civil Engineering and Management (JCEM), Journal of Management in Engineering (JME) and Procedia Engineering (PE). The selection of these papers had to go through a gate of primary filtration. Specifically, any papers written earlier than 2011 were not considered in this paper. In addition, the category of these journals must be checked, and it should be at least in a Q1 or Q2 category. Moreover, a syntax was used to find specifically the topic for instance “Causes of Construction delays,” and “Analyzing factors affecting construction delays.”
3. CAUSES OF DELAYS The cause of delays is gathered through literature review and of several resources and categorized then in three common themes between papers as follows: 3.1 Causes identified as the risk of project delays Exploring Delays in Victoria-based Australian Pipeline Projects Paper discusses the delays on the pipeline project in Victoria Australia and identifies the causes and the risk and suggests a risk mitigation plan and how to control the outcomes of the project with no impact.
