Long-term coverage
Resident Inspectors in Vietnam
For manufacturing programs lasting several weeks or months, occasional inspection visits may not provide sufficient visibility over production progress, technical deviations and supplier performance.
Dilenza can provide resident inspectors in Vietnam who remain directly at or close to the supplier facility and continuously monitor critical manufacturing activities, inspection points, testing, non-conformities and corrective actions.
Resident inspection is particularly suited to:
- Large fabrication projects
- Shipbuilding programs
- Steel structures
- Industrial equipment
- Energy equipment
- Pressure equipment
- Piping systems
- Machinery
- Multi-stage manufacturing programs
Depending on your project requirements, coverage can be provided by one dedicated inspector, several technical specialists or a rotational inspection team.
