Evaluation of the reasons of delay for construction projects under terrorism risk

Abstract

One of the most common issues in the construction industry is the delay problem. The majority of the researchers have been focused to study the delay reasons in the implementation phase while few of them adopted to discuss the delay reasons for the early phases for the project planning and design phases. Therefore, this paper aims to study the reasons of the project delay in the planning and design phases as well as the implementation phase during the period of terrorism. A questionnaire included the delay reasons for the three phases that have been sent to the questioners of engineers who are working in the public and private Iraqi construction industry. The valid responses have been tested using Chi-Square Test to indicate the validity and reliability of the results and the relative importance index (RII) to show the average repetition of delay happening. The results showed that the main direct reason causes a delay in the planning phase is the unavailability of the fundamental data for the. Whereas, projects the design phase the analysis of the questionnaire results specified the owner’s financial issues was the significant delay reason. Moreover, the most effective delay’s reason in the implementation phase is the terrorist acts and cut off roads.
