Purpose Despite extensive research on Internet of Things (IoT) applications in the construction industry, there remains a critical gap in understanding its systematic implementation and effectiveness, specifically within construction supply chain management (CSCM). This study aims to provide a systematic review of IoT applications in CSCM, highlighting their current applications, associated challenges and emerging integration pathways. Design/methodology/approach A PRISMA-based systematic literature review was conducted, drawing on 28 peer-reviewed journal articles and conference papers from Scopus and Web of Science for bibliometric and qualitative content analysis. Findings The review shows that IoT has moved from isolated tracking solutions (e.g. Radio Frequency Identification-based logistics) to integrated ecosystems that combine Building Information Modelling, blockchain and digital twins to enhance visibility, traceability and coordination. Applications span areas such as real-time tracking, logistics optimisation, risk management, sustainability reporting and automated financial trust mechanisms (e.g. IoT-enabled smart contracts). However, widespread adoption is constrained by technical limitations, data governance issues, trust and cybersecurity concerns, organisational inertia and uncertain return on investment (ROI). The findings of this study highlight that IoT’s transformative value lies in its integration with complementary digital technologies, creating interoperable, governance-driven systems that improve collaboration, resilience and sustainability. Originality/value This study consolidates fragmented knowledge on IoT in CSCM, offering a structured synthesis of the construction supply chain’s current landscape. This review contributes a foundational roadmap for researchers and practical guidance for industry stakeholders seeking to leverage IoT for enhanced transparency, efficiency and sustainability in construction supply chains.
