High-capacity dam: obtain authorization for construction, modification, demolition or operating changes
Classify the dam and work, engage professionals, file plans and safety measures, then certify compliance.
Unauthorized work can endanger people downstream. For an anomaly or immediate risk, first apply emergency measures and notify the authorities.
Confirm the scope
Check the registry classification and whether construction, structural work, demolition, use change or closure requires prior authorization.
Prepare the information
Engage an engineer and gather project notice, plans, specifications, attestations, calculations, schedule and prescribed information.
Complete the process
Update the water-management and emergency plans when required and send the file to the Dam Safety Directorate.
Keep follow-up records
Await authorization, follow approved plans, give completion notice and submit the compliance attestation on time.
