Identifying and assessing the impact of 4M1E factors on construction project delays in Afghanistan using structural equation modeling

Construction projects in Afghanistan are often challenged by significant delays, posing severe challenges to their successful completion. This study aims to comprehensively assess the impact of various delay factors using the 4M1E framework Man, Machine, Material, Method, and Environment within the Afghan construction sector. By employing a validated Structural Equation Modeling (SEM) approach, the research investigates both direct and indirect effects of these factors on project delays. The analysis reveals that environmental and material factors are particularly influential, with environmental changes often exacerbating delays across other dimensions. The findings underscore the complex interdependencies among the 4M1E factors, highlighting the need for targeted strategies to manage the delay effectively. Practical recommendations are provided to enhance project management practices, with implications that extend beyond Afghanistan to other developing countries facing similar challenges. This study contributes to the academic discourse on construction delays, offering actionable insights for practitioners, policymakers, and stakeholders in the construction industry.
