The project involved the deconstruction of an upstream raised tailings storage facility (TSF) in Mexico, involving the relocation of 145,000 m³ of tailings. Due to missing construction records, a “digital twin” was created from field data to model the TSF, assess risks, and plan safe deconstruction. Tailings were moved using excavators and dump trucks with sealed tailgates. Engineers monitored the dam’s performance and collaborated with stakeholders to adapt deconstruction methods as conditions varied. Tailings relocation rates ranged from 820 m³/day to 1,810 m³/day, with challenges and adaptations discussed and addressed throughout the process.
