As a result of the review—which revealed the need for improvements and, in some cases, design modifications—INVIAS has significantly improved its environmental and social management systems and is currently implementing processes and specifications to ensure proper management and accountability in five key construction management areas: erosion, drainage control, and slope stabilization; criteria for the opening and restoration of access roads; worker health and safety; a registry for non-conformities, corrective actions, and their closure; and environmental and social indicators to monitor progress.
