Ghanaian Construction Workers’ Health and Safety Knowledge and Compliance

Purpose: This study seeks to assess the knowledge level of local construction workers regarding health and safety measures on construction sites. Design/Methodology/Approach: A quantitative research approach was employed, using interval Likert-type scales to measure data. A purposive sampling technique was employed for the study. One hundred and fifty questionnaires were distributed, with 122 returned and deemed valid for analysis. Descriptive statistics, relative importance index, Pearson Correlation, and structural equation modelling were utilised for the study. Data analysis was conducted using Amos 28 through structural equation modelling. Findings: The results indicate that the level of knowledge in construction health and safety practices directly and indirectly affects project performance and productivity. Higher levels of knowledge were associated with higher compliance with construction health and safety practices, leading to increased project performance and productivity. Compliance with health and safety measures directly influenced project performance and productivity. Additionally, the level of knowledge had a positive indirect effect on project performance and productivity. Research Limitations: Primarily, the sample was confined to construction workers within specific regions of Ghana, which may limit the applicability of the results to other geographic areas or contexts. Additionally, using self-reported data through questionnaires could introduce bias, as participants may respond in ways they perceive as socially desirable rather than reflecting true behaviours and knowledge levels. Practical Implication: Construction firms and authorities should prioritise safety training and tight safety regulations. Knowledge and compliance boost project performance and efficiency, making them a compelling financial case for investment. Companies could integrate advanced training modules and ongoing learning opportunities to maintain safety knowledge and compliance leading to more efficient and safer construction methods. Social Implications: The study shows substantial social consequences for construction worker health and safety. It emphasises the need for improved education, regulation, and compliance to reduce workplace injuries and fatalities. Originality/value: It contributes to understanding the relationship between project performance and productivity in a complex construction environment.
