This study explored the factors affecting material supply chain efficiency in road construction projects in Nueva Ecija, Philippines. Using a qualitative case study design, interviews were conducted with 10 key informants, including engineers, contractors, consultants, and government personnel. Data were analyzed using thematic analysis, resulting in six main themes: environmental challenges, impact on project timelines, regulatory and administrative challenges, coordination problems with agencies, strategies used by practitioners, and suggested improvements. Findings indicate that heavy rainfall, flooding, soft soil, and bureaucratic delays significantly affect supply chain efficiency. Practitioners adopt adaptive strategies such as soil stabilization, rescheduling, and early permit submission. Recommendations include digitalized permit processing, unified LGU–national agency guidelines, proactive planning, and inter-agency coordination. These measures aim to reduce delays, enhance efficiency, and improve overall project performance.
