ASSISTANT MANAGER

Here’s an overview of Quality Control (QC) in EPC (Engineering, Procurement, and Construction) industries:

🔹 Role of Quality Control in EPC

In EPC projects—such as power plants, oil & gas, infrastructure, and industrial facilities—Quality Control ensures that engineering, materials, and construction meet required standards, codes, and client specifications. QC is a critical part of the wider Quality Management System (QMS) and directly impacts safety, reliability, and cost efficiency.

🔹 Key Objectives of QC in EPC

1. Compliance – Ensure all work complies with codes, standards (ASME, ASTM, ISO, API, IEC, etc.), and client specifications.

2. Defect Prevention – Detect and correct issues at the earliest stage (design, procurement, fabrication, or construction).

3. Risk Mitigation – Reduce failures, accidents, and rework during operations.

4. Documentation & Traceability – Maintain proper inspection reports, test certificates, and quality records.

5. Client Satisfaction – Deliver projects with zero defects and within timelines.

🔹 QC Activities Across EPC Phases

1. Engineering Phase

• Design document reviews (drawings, datasheets, specifications).

• Verification of engineering calculations.

• Independent design checks and approvals.

2. Procurement Phase

• Vendor evaluation and approval.

• Material test certificate (MTC) review.

• Factory Acceptance Tests (FAT).

• Inspection at vendor works.

3. Construction / Execution Phase

• Incoming material inspection.

• Welding inspection (WPS, PQR, welder qualification, NDT).

• Dimensional checks, alignment, tolerances.

• Electrical and instrumentation testing.

• Civil works quality checks (concrete strength, soil compaction, etc.).

• Hydrostatic, pneumatic, leak, and functional testing.

4. Commissioning & Handover Phase

• Pre-commissioning checks.

• System turnover packages with inspection reports.

• Punch list clearance.

• Final acceptance tests with client.

🔹 KPIs for QC in EPC

• % of inspections passed at first attempt.

• Number of NCRs (Non-Conformance Reports) raised and closed.

• Rework hours vs. total work hours.

• Material rejection rates.

• Client satisfaction & handover without penalties.
