Advancing materials procurement processes in construction: A framework for optimising technology integration in SMEs' construction supply chains

Materials procurement is a key challenge for construction SMEs, often hampered by limited resources, manual workflows, and poor communication. This study introduces a scalable framework that leverages accessible digital tools—such as mobile apps, RFID, and cloud-based systems—to streamline procurement. A mixed-methods approach, including case studies, interviews, surveys, and observations, was used to evaluate the framework across six SMEs in various construction sectors. Results showed notable gains: a 34% reduction in order processing time, a 25% drop in material waste, and a 35% improvement in inventory accuracy. These improvements were statistically confirmed and attributed to the framework's components. The model's phased rollout eased financial and training pressures, while built-in feedback loops allowed SMEs to adapt procurement practices to evolving project and supplier demands. By addressing real-world implementation barriers, the study provides a practical, validated roadmap for digital transformation tailored to SME needs. The framework not only improves cost control and delivery timelines but also enhances competitiveness in a digital construction landscape.
