Delays in residential construction projects are common issues in both developing and developed countries. This research aims to identify the key reasons behind these delays in Pakistan. When the projects run behind schedule, this can lead to problems such as exceeding the budget, reduced productivity at the construction site, and potentially lower quality work. The study involved a detailed survey using questionnaires that were addressed to industry professionals. Their responses were used to rank the critical factors causing delays. The most significant factors were found to be fluctuating material prices, financial challenges for contractors, underestimating project duration, poor site management, inexperienced contractors, ineffective project management, communication gaps among project stakeholders, shortage of skilled workers, changes in project design, unqualified contractors, and inadequate project planning. Identifying these critical factors through the Relative Importance Index (RII) method can help in addressing and preventing delays in Pakistan's construction projects, ensuring timely completion and better project outcomes in the future.
