abstract={Construction supply chains are often affected by inefficiencies, delays, material wastage, and carbon emissions, with implications for both project performance and sustainability. Although lean and green supply chain management (GSCM) approaches have been studied extensively, evidence on their integrated, project-level application in construction remains limited, especially in developing economies. This study proposes a comprehensive framework designed to enhance operational efficiency while promoting sustainability within the construction sector by integrating Lean and GSCM. The framework integrates Value Stream Mapping (VSM) to identify and redesign inefficient processes, with VSM-based Discrete Event Simulation (DES) to quantitatively demonstrate how lean interventions translate into environmental benefits across the construction supply chain. The proposed framework is validated through a real-world case study of a water supply pipeline distribution project in India. The results demonstrate that lean-driven supply chain redesign leads to an 8% reduction in total cycle time and inventory levels, while simultaneously achieving 7% decrease in carbon emissions. The integration of VSM and simulation enables construction practitioners and project managers to evaluate the operational and environmental implications of lean supply chain redesign in advance, reducing implementation risk and supporting informed decision-making at the project level. },
