The performance of construction projects is a key factor in the success of modern infrastructure development, particularly in achieving cost, quality, and schedule targets. Road improvement projects at PT X face operational challenges, including delays in the delivery of prefabricated materials and extreme weather conditions, which may reduce daily work productivity. This study aims to identify the dominant factors affecting project performance, determine their relative importance using the Relative Importance Index (RII) method, and formulate appropriate control strategies. A quantitative approach was employed using questionnaires distributed to 30 project personnel, of which 28 valid responses were returned and analyzed. The questionnaire consisted of 15 variables related to factors affecting project performance. The RII values were classified into three importance levels: high, moderate, and low. Although three classification levels were used, the results showed that the analyzed variables fell only into the high and moderate categories. The two most dominant factors were the suboptimal internal quality management system, with an RII of 0.700, and the lack of coordination among parties in quality control, with an RII of 0.686. The proposed control strategies include conducting periodic quality audits, assigning dedicated supervisors at critical project stages, and strengthening integrated materials supply chain management. These strategies are expected to improve project implementation efficiency at PT X and provide a useful reference for future road infrastructure projects.
