Delays are a common challenge in construction projects, often resulting in significant impacts on budgets and schedules. This research presents a case study investigating the efficacy of various delay analysis techniques in construction projects. Utilizing data collected from a live project, the study applies a range of techniques including CPM-Based As-Planned Technique, As-Built Technique, but-for Technique, Window Analysis and non-CPM-based Global Impact Technique. Through implementation and analysis, the limitations of each technique are identified, enabling a comparative assessment of their effectiveness. The study aims to choose the delay analysis method that is best for the particulars of the project., considering factors such as accuracy, ease of application, and comprehensiveness. By providing insights into the strengths and weaknesses of each method, this research contributes to enhancing delay management strategies in construction projects.
