Factors affecting delay of construction projects

Abstract

The research is aimed to 1) study the level and priority of the factors affecting the delay of construction projects and 2) provide suggestions in relation to the prevention of such delay. The sample is 520 people who were working for different construction projects. They were project managers, project engineers, field engineers, and foremen. The data were collected by using online questionnaires and analyzed to find out mean, standard deviation (SD), frequency, correlation coefficient, and confirmatory factor analysis. The findings reveal two significant aspects. First, those who were working in the construction projects concerned about the factors affecting the delay of the projects at high level. Respectively, the factors related to design, resource, external factors and others were taken into consideration. The factor regarding to work performance is regarded affecting the project delay at the highest level. Other factors, i.e., the design, external factors and others, and resource have the affects at the lower level. Second, the work-related factors can help prevent the project delay. In other words, the construction plan and methods as well as the project management should be well-implemented in accordance with the design. The construction site should be on inspection considering its drawing. Regarding the external factors and others, the public voices of those living around the construction site should be taken into consideration. Furthermore, the effective use of the resources can be carried out by sufficiently preparing all materials, tools, and equipment for constructing any project effectively as a consequence.
