The construction projects parties seek to successfully accomplish projects on schedule, within the budget, with high quality and in a safe manner and environmental limits. However, the execution of construction projects is subjected to several constraints and risks that limit their start or progression operations, which regularly have a significant negative impact on overall projects performance. Most research only considered the internal factors affecting the project performance and overlooked the external factors in spite of their importance. The aim of this research is to investigate the external factors effect on project performance. The literature is reviewed and found that most external factors can be represented by PESTLE factors. Consequently, this research provides a conceptual model for the PESTLE factors effect on project performance in terms of time, cost, and quality. External factors are unpredictable and may generate effects that cannot be easily remedied without significant losses; therefore, it’s more important to investigate their effects on construction project performance. Understanding the effect of these factors is key for nations to manage risks, control outlays, exploit and benefit from opportunities.
