This study aims to evaluate and prioritize the supply chain performance of a public construction project in a remote region—namely, the eight-story office building of Bank Indonesia in West Papua. The research adopts a mixed-method approach integrating a quantitative assessment using the Green Supply Chain Operations Reference (Green SCOR) model with a qualitative weighting of indicators through the Analytic Hierarchy Process (AHP). Nineteen key performance indicators (KPIs) were evaluated across five dimensions: reliability, responsiveness, agility, cost, and asset management. Data were collected from 66 stakeholders—including project owners, consultants, contractors, and suppliers—who contributed expert judgment for the AHP analysis. The results indicate that the overall performance level is 58.68%, categorized as average, highlighting the need for optimization. The analysis identifies Cash-to-Cash Cycle Time as the most influential KPI, followed by On-Time Delivery of Materials and Total Supply Chain Management Cost. Due to the average performance level, a Root Cause Analysis (RCA) using the 4M + 1E framework was conducted to explore inefficiencies. The RCA revealed challenges in workforce competence, digital system adoption, material forecasting, supplier dependency, and environmental constraints. Practical implications include integrating digital platforms, AI-based forecasting, supplier diversification, and multimodal logistics strategies. This research contributes to Sustainable Development Goal 9 by promoting resilient, inclusive, and sustainable infrastructure systems in geographically isolated regions.
