Bureau Veritas Mongolia successfully completed contributions to the Oyu Tolgoi Underground Mine project, one of the most largest and technologically complex mining projects globally.

In partnership with Worley, we were seamlessly integrated into the client's quality framework, entrusted with pivotal QA/Qc responsibilities and innovative solutions across various sectors and project phases.

Our comprehensive services at Oyu Tolgoi included: 

- Oversight of civil, structural, mechanical, piping and electrical works;

- Review and enforcement of Inspection & Test Plans (ITPs);

- Conventional and advanced Non-Destructive Testing (NDT) and welding inspections;

- Compliance audits adhering to ASME, AWS and ISO standards;

- Rigorous adherence to Health, Safety and Environment (HSE) and access protocols under Rio Tinto governance.

This collaboration underscores Bureau Veritas' capability to deliver exceptional support for large-scale, high-risk projects with a multi-disciplinary scope, aligning with government and critical infrastructure standards.

We extend our appreciation to the entire Mongolia team. Your hard work have been instrumental in achieving this remarkable milestone.
