Security of payment (SOP) issues still persist in the construction industry despite numerous investigations and incremental reforms. Various solutions and policies have been proposed and analysed in-depth in previous studies. However, limited studies have focused on the integration of advanced technologies to address SOP issues. The aim of this research is to develop a comprehensive framework that integrates practical advanced technologies to address SOP issues in the construction industry. A concurrent mixed-method design was adopted to (a) identify the industry's perspective on what advanced technologies can be accepted to address SOP issues through a questionnaire survey, and (b) identify the use of advanced technologies through a live construction project as a case study. Subsequently, a data flow diagram framework was developed to articulate the whole process flow of how the system delivers automatic payments to subcontractors upon the completion of their contractual obligations and work done. This research contributes new and practical insights into the application and integration of smart sensors, oracles, BIM, blockchain technology and smart contracts in addressing SOP issues in the construction industry.
