Organizational learning stems from the synergy of human resources, using their qualification in the results of projects whose maturity may be assessed based on metrics that are still unavailable. These metrics are the first contribution of the present study. The analysis of two case studies of complex terminals, guided by the Front-End Load culture of gate approval for strategic advancement as a business organization, shows that audits are essentially able to measure the level of stakeholders in their consulting, inspection, management, and contractor roles, thereby assessing their productivity and, moreover, their ability to perform the contract without exceeding risks, costs, and deadlines. The analysis clearly shows that the audit should be used as a tool for project maturity certification in heavy civil construction based on this study.
