Responsibilities

Includes but not limited to the following:

Quality Assurance and Compliance

• Verify that the supplier’s Quality Management System aligns with ISO 9001 and project-specific QA/QC requirements.
• Review and approve manufacturing procedures, mix designs, prestressing records, curing process, and dimensional control reports.
• Ensure implementation of the approved ITP and witness points in accordance with the Project Quality Plan.
• Monitor periodic mold calibration, gauge verification, and test equipment certification.
• Verify the traceability of materials (cement, PC wire, aggregates, steel inserts, etc.) and their certificates of origin and compliance.
• Ensure full implementation of corrective and preventive actions (CAPA) for any nonconformities.
• Issuance of nonconformities, monitoring, follow-up, and closure.

Production Monitoring

• Supervise day-to-day sleeper casting operations, including batching, tensioning, curing, demolding, and finishing.
• Witness key hold points such as pre-tensioning, concrete pouring, and post-tension release.
• Confirm that sleepers meet all dimensional tolerances and visual inspection criteria before acceptance.
• Monitor production rates and alignment with the approved manufacturing schedule.

Testing and Documentation

• Witness routine laboratory and field tests: compressive strength, density, water absorption, static/fatigue load tests, and dimensional checks.
• Review all test results, ensure timely submission of reports, and verify statistical sampling compliance.
• Ensure that calibration certificates for measuring and testing equipment are valid and updated.
• Maintain comprehensive daily logs, inspection reports, and nonconformance records.

Coordination and Reporting

• Coordinate with the Supplier’s QA/QC Manager and Engineer, and Colas Rail representative during audits or inspections.
• Support factory audits, FAI, FATs, and third-party inspections (e.g., by ENG/DOTr).
• Issue daily, weekly, and monthly quality reports summarizing progress, test results, and quality performance indicators.
• Liaise with the Japanese stakeholder representative at the factory regarding quality alignment and continuous improvement measures.

Pre-Shipment Verification and Authorization

• Prior to shipment of PSC sleepers, verify that the packing list fully corresponds to the physically inspected and accepted materials, ensuring correct quantities, identification marks, and batch traceability.
• Confirm that all relevant inspection documents, test certificates, and acceptance reports are complete and properly referenced in the shipping dossier.
• Ensure that sleepers are properly handled, stored, and loaded in accordance with the approved logistics and packing procedure.
• Provide formal written authorization (“GO for Shipment”) only once all quality and documentation requirements have been satisfactorily fulfilled and duly recorded.
• Report any discrepancy or deviation to the trackworks project manager and quality team of MMSP.
