Abstract As buildings are now taller, larger, and more complex, it has become increasingly more difficult to secure stockyards for materials and to resolve the surrounding traffic problems, creating an increased need for Just-In-Time (JIT) delivery. To support JIT delivery, it is necessary to build a framework that can facilitate the collection and share of information on construction components and material flow throughout the whole supply chain process. Many researchers have suggested that radio frequency identification (RFID) and wireless sensor network technologies could improve the effectiveness and efficiency of JIT management. In addition, service-oriented architecture (SOA), the services of which enable the interfacing of a heterogeneous system environment of parties involved in the supply chain management process, is suggested in the manufacturing industry as one of the solutions for effective collection and sharing of information in supply chain management. However, the construction industry has limits in applying the framework suggested in the manufacturing industry since the supply chain process in the construction industry is extremely dynamic due to frequent changes in the design and plans of construction projects. Therefore, the objective of this research is to develop a seamlessly integrated information management framework that can provide logistics information to project stakeholders for their decision making. The pilot test of the framework developed in this research showed that it can improve time efficiency by about 32% compared to the traditional supply chain management. The result of this research is expected to be utilized effectively as a basic framework to manage information in RFID/WSN based construction supply chain management (CSCM) environments.

Research Highlights ► SOA and RFID/WSN-based information framework can improve constr. supply chain mgmt. ► 25 services are proposed to support SOA-based construction supply chain process. ► Smart management of equipment flow in the supply chain can improve its process. ► The test result showed the proposed system could improve 32% over the as-is process.
