This paper presented a cloud-based material tracking system for SMB contractors to improve supply chain visibility (e.g. fabrication, delivery, and installation processes). The system integrates not only RFID for automated tracking but also a barcoding system for backward compatibility and minimal interruption in the existing workflow. The selected cloud platform provided a cost-effective solution to overcome the errors and delays in information flow and enhance collaboration in the construction supply chain. The test results indicate that the proposed system is effective but there is room for improvements, particularly on the reliability of RFID system; however, this can be tackled by using more reliable RFID readers and tags and by finding good reader
and tag configurations for the working environment.
