Abstract
The construction sector plays a vital role in the development of the country’s economy and infrastructure. But a construction project delay is a significant problem for project success. The main objective of this paper was to analyze the cause and effect of construction project delay with particular reference to Ethiopian Airlines. This study adopted a descriptive research design with a quantitative approach. The data were gathered from primary sources using structured questionnaires administered to Ethiopian Airlines employees, contractors, consultants, and other stakeholders in Ethiopian Airlines construction projects. The responses of 73 participants were examined using Statistical Package for Social Sciences (SPSS) to execute descriptive analysis, correlation analysis, and regression analysis. The analysis shows most common causes of project delays were contractor
related causes, client related causes, consultant related causes, shortage of materials, shortage of labor, and external causes such as inflation and regulatory delays. Contractor inefficiency, delayed decision making, poor planning, shortage of materials, and financial constraints were the major causes of delay. The study further revealed that project delays lead to time overruns, cost overruns, disputes between stakeholders, productivity loss, and hinder organizational growth. It concluded that project delays in Ethiopian Airlines construction projects were affected by several interrelated factors that need to be managed holistically. This suggests that improving project planning, collaboration among stakeholders, timely payment of funds, and improving contractor performance are key factors to reduce delays and increase the success of projects.
