Document review before fabrication starts prevents most of the non-conformities that would otherwise be found on site. Zen Teknik independently assesses the alignment of technical documents between designer, fabricator and client.
Documents we review
- Fabrication drawings: welding symbols (EN ISO 2553), joint preparation details, EXC/quality level assignments
- Welding plan and WPS list: range conformity (matching with WPQRs)
- Inspection and test plan (ITP): NDT percentages, acceptance criteria, witness/hold points
- Quality plan, material list and certificate requirements
- Painting/coating specification and procedures
- Pressure test, heat treatment and erection procedures
