Lean construction concepts prioritize optimizing project value while minimizing waste and unnecessary resources. This theory also applies to the critical domain of supply chain management. Construction projects can gain substantial enhancements in efficiency and cost management by incorporating lean technologies such as Value Stream Mapping (VSM), 5S, and Just-in-Time (JIT) delivery. By implementing VSM, 5S methodology, and JIT practices, construction projects can achieve improved transparency and management of their supply chains. The VSM methodology enables the identification of flaws and chances for improvement, whereas the 5S methodology assures an organised and efficient flow of materials. JIT delivery reduces inefficiency and improves inventory control. Construction projects can assess the efficiency of their lean supply chain processes by tracking key performance indicators (KPIs) such as lead times, inventory turnover, and rework rates. By utilising a data-driven strategy, it becomes possible to consistently enhance and pinpoint areas in which the supply chain may be further reinforced. This research aims to conduct a systematic literature evaluation and case study application to assess the efficacy of lean technologies in promoting sustainability in the construction supply chain. The results suggest that implementing lean principles such as VSM, 5S, and JIT can significantly enhance and optimize the green supply chains of construction projects. By employing these techniques, construction projects can effectively achieve sustainability, enhance project efficiency, and complete projects within the designated timeframe and budget.
