Development and validation of a framework for improving health and safety risk management at informal construction sites in Tanzania

Purpose Although there are several established frameworks for health and safety in construction, there are inadequate health and safety conditions at informal construction sites, and no framework has been designed to address this problem. The purpose of this paper is to develop a validated framework for health and safety risk management (HSRM) in informal construction sites with the aim of supporting Sustainable Development Goals 3, 8 and 11 of the 2030 Agenda, which are to ensure everyone enjoys a healthy life and to create inclusive, secure, robust and sustainable cities and human settlements, respectively. Design/methodology/approach The study is based on HSRM questionnaire survey and interviews with construction workers working on informal construction sites in Tanzania. A total of 13 health and safety specialists in construction were specifically chosen to validate the proposed framework for HSRM in informal construction to determine its applicability, efficacy and adaptation. Findings The validation results demonstrated that all of the suggested metrics within the framework for HSRM in informal construction scored higher than the test value, proving the framework’s feasibility Originality/value This research adds to the body of knowledge on the issue in a never-before-seen setting. To the best of the authors’ knowledge, this study is the first empirical study in Tanzania to develop and validate a framework for HSRM in informal construction.
