Abstract
Project delays can arise from multiple sources, including weather conditions, logistical challenges, and unexpected site conditions. This study aims to identify the primary factors influencing the progress of highway construction, specifically focusing on the Ring Road Junction Improvement Project at Lebu Intersection. Through extensive data collection, including literature reviews and other research methods, a total of 59 delay factors were identified and categorized into five main groups: Planning, Management, Financial, Technical, and Material factors. Questionnaires containing these factors were distributed to 70 professionals involved in the Lebu Intersection Project, resulting in 67 successfully collected responses. The collected data was analyzed using both quantitative and qualitative approaches with SPSS and Microsoft Excel. The analysis, incorporating responses from Clients, Contractors, and Consultants, revealed that the most significant delay factor, with a Relative Importance Index (RII) value of 0.83, falls under the Management category. Based on these findings, the study recommends that project stakeholders prioritize selecting competent project managers and consulting firms. It also suggests proactive measures to address "Right of Way" issues before project commencement. Experienced engineers emphasized the critical role of rigorous supervision and control by all involved parties to enhance project performance and mitigate delays. Ultimately, understanding and mitigating these factors are essential for achieving successful outcomes in highway construction projects like the Ring Road Junction Improvement Project at Lebu Intersection.
