Background: Substantial empirical research has shown conflicting results regarding the influence of organizational external factors on construction risk management, suggesting the necessity to introduce a moderator into the study. The present research confirmed whether rules and regulations matter on the relationships between organizational external factors and construction risk management. Methods: Based on discouragement and organizational control theory, this research examined the effects of organizational external factors and rules and regulations on construction risk management among 238 employees operating in construction companies in Abuja and Lagos, Nigeria. A personally administered questionnaire was used to acquire the data. The data were analyzed using partial least squares structural equation modeling. Results: A significant positive relationship between organizational external factors and construction risk management was asserted. This study also found a significant positive relationship between rules and regulations and construction risk management. As anticipated, rules and regulations were found to moderate the relationship between organizational external factors and construction risk management, with a significant positive result. Similarly, a significant interaction effect was also found between rules and regulations and organizational external factors. Implications of the research from a Nigerian point of view have also been discussed. Conclusion: Political, economy, and technology factors helped the construction companies to reduce the chance of risk occurrence during the construction activities. Rules and regulations also helped to lessen the rate of accidents involving construction workers as well as the duration of the projects. Similarly, the influence of the organizational external factors with rules and regulations on construction risk management has proven that most of the construction companies that implement the aforementioned factors have the chance to deliver their projects within the stipulated time, cost, and qualities, which can be used as a yardstick to measure a good project.

Abstract— Over the past years, construction risk management in projects execution is always associated with uncertainties because certain risk factors such as poor labour productivity, shortage of equipment, delay, cost overrun, time overrun are attributed to project delivery. These risk factors have been generating many research interests among the construction stakeholders and the policymakers, necessitating this present study. In addressing this issue, this study utilized Partial Least Squares- Structural Equation Modeling method to validate construction risk management (CRM) as a construct from the viewpoints of multi-national, local and national construction companies in Nigeria. Through a cross-sectional survey, data were collected from the construction companies with the use of a structured questionnaire. It was discovered that technology, political and economic factor have a significant influence on construction risk management (CRM) among the Nigerian construction companies. A substantial degree of convergent validity, discriminant validity and internal consistency reliability were also affirmed for each of these research constructs. It was also discovered that the indicators of organisational external factors dimensions (technology, political and economic factor) are important in evaluating these constructs for further exploration of the construction companies to enhance risk management practice in all stages of the project activities.
