Material delays remained one of the most critical challenges affecting the performance of construction projects in Sorong, Southwest Papua, where geographical isolation, limited logistics capacity, and supply-chain disruptions frequently extended project timelines. This study aimed to identify and validate a context-specific list of material delay risks by applying the Content Validity Index (CVI) to ensure that the selected risk indicators accurately represented the conditions of construction projects in the region. A descriptive–qualitative approach was employed, involving eight experts with a minimum of five years of experience in construction project management in Southwest Papua. Twenty-nine risk events and twenty risk agents derived from the literature were assessed using a 1–4 relevance scale. The results indicated that 14 risk events and 13 risk agents achieved acceptable validity, with I-CVI values ranging from 0.88 to 1.00. The high S-CVI/Ave (0.98) and S-CVI/UA (0.87 for risk events; 0.86 for risk agents) demonstrated strong consensus among experts and confirmed the robustness of the research instrument. These findings suggested that the validated risk list accurately reflected dominant material delay issues in Sorong and was appropriate for subsequent quantitative risk analysis. The validated items were further interpreted as essential inputs for the next phase of research, particularly in applying Failure Mode and Effect Analysis (FMEA) and the House of Risk (HOR) to prioritize dominant risk agents and develop targeted mitigation strategies. This study recommended broadening expert representation in future validations and integrating digital early-warning systems to strengthen material management practices in the region. The validated risk framework provided practical implications for contractors, policymakers, and supply-chain stakeholders in improving project reliability in Sorong.
