ABSTRACT

This paper has attempted to review the research behavior of publications on factors causing time delays in construction projects. A total of 46 publications since 1985 have been selected and reviewed for reported delay factors. A rigorous methodology is adopted for consolidating factors indicated by different publications, to represent generic factors causing delay in construction projects. A total of 128 factors are consolidated under three basic project stages of feasibility, design, and construction. Each project stage is then further categorized under two levels to illustrate specific domains of a construction project. A discussion is then performed to analyze how publications through time have been changing their focus from one area of construction to other to address delay. It is identified that in earlier times, publications limit their focus to the site activates only to manage delay; but then with the passage of time other areas such as procurement, material inventory and logistics, project management etc. have become a focus of recent publications. A chronology of delay factors is then developed. This paper will help academic and professional researchers and industry professionals to understand the possible factors that can influence a construction project; and how all these factors have been historically envisaged.
