Safety Knowledge Management in Construction Industry: A Systematic Literature Review of Performance Measurement Indicators

The continuing rise of construction accidents reflects critical failures in safety knowledge and its transfer across project teams. Although knowledge management (KM) holds significant promise for enhancing safety practices, its implementation has not been systematically evaluated due to the absence of integrated performance measurement tools. This study addresses this gap by conducting a systematic literature review (SLR) using the PRISMA method. A total of 109 peer-reviewed articles published between 2009 and 2024 were retrieved from the Scopus database. The findings produced a comprehensive set of Safety-KM indicators consisting of two core dimensions: KM processes and KM enablers, covering nine variables and seventy-seven specific indicators. Additionally, this study explores the mechanisms linking KM processes and enablers in supporting safety knowledge across construction projects. The proposed Safety-KM framework and measurement indicators contribute theoretically by integrating fragmented KM components into an evaluation model. Practically, it provides actionable guidance for contractors and regulators to assess, implement, and improve KM practices, ultimately enhancing construction safety performance.
