The Role
You'll own QA/QC delivery across the full lifecycle of a project — from material verification and fabrication inspection through pressure testing and final documentation — working closely with clients, PMT, subcontractors, and notifying bodies to ensure every weld, joint, and system meets code, spec, and Gradiant's own standard of quality.
Key Responsibilities
Inspection & Testing
- Perform visual, fit-up, and material inspections against drawings, WPS, MDR, and MIL certificates.
- Verify cutting plans against actual material cutting and monitor NDE coverage against project requirements.
- Review piping pressure test packs and compile weld and material summary reports.
- Conduct site inspections at subcontractor workshops and coordinate witness inspections with clients and third parties.
Quality Assurance & Compliance
- Ensure construction quality aligns with the approved Project Quality Plan, applicable codes, and client specifications.
- Raise NCRs for non-compliance, determine material disposition, and drive corrective and preventive actions to closure.
- Lead QA/QC audits and surveillance to catch issues early and prevent costly rework.
- Keep calibration records for measuring tools current and drawings at the latest revision.
Documentation & Reporting
- Maintain the full QA/QC record set — certificates, calibration logs, test results, inspection requests, and site instructions.
- Issue daily RFIs, compile final documentation for client acceptance, and submit weekly reports to the QC Supervisor.
Coordination & Stakeholder Management
- Represent Gradiant in construction and technical meetings, client quality walks, and daily toolbox talks.
- Liaise with the QA/QC Manager, notifying bodies, vendors, and subcontractors to keep quality aligned across every discipline.
- Deliver quality orientation sessions for piping to PMT, QC, and subcontractor teams.
Health, Safety & Environment
- Uphold HSE requirements on-site and contribute to weekly safety briefings.
