Identifying the Key Factors Affecting the Success of Occupational Health and Safety Management during the Implementation of Construction Projects for NGOs in Sana’a, Yemen
The critical role of Occupational Health and Safety (OHS) management in supporting construction project success is especially evident in fragile contexts such as Yemen. This study identifies the key factors affecting the success of OHS management during the implementation of construction projects executed by non-governmental organizations (NGOs) in Sana’a and explores the main challenges that hinder effective implementation. A quantitative design was employed using a closed-ended questionnaire derived from the requirements of ISO 45001:2018, which was distributed to professionals involved in NGO construction projects. Participants were selected through purposive (non-probability) sampling methods. A total of 384 questionnaires were distributed, and 171 valid responses were received and included in the analysis, yielding a response rate of 44.5%. Data were analyzed using the SPSS software. The instrument demonstrated excellent internal consistency (Cronbach’s α = 0.972). The results indicate that top management commitment, strengthening the OHS culture, and allocating adequate resources are the most influential factors associated with successful OHS management. The most critical implementation challenges were related to the social and cultural context and the provision of personal protective equipment. This study recommends institutionalizing ISO 45001-based OHS management systems in NGO construction projects, strengthening leadership accountability, and ensuring adequate resourcing, training, and monitoring to improve OHS performance in construction projects in Yemen.
