What is an Inspection & Test Plan (ITP)?

Ada satu dokumen wajib semua inspector kena faham — Inspection & Test Plan (ITP). Pernah tengok, tapi tak ramai faham struktur & cara gunanya.

Inspection & Test Plan (ITP) ialah dokumen Quality Assurance yang menyusun semua checkpoint inspection & testing mengikut urutan kerja. Ini termasuk:

• Bila perlu inspect

• Apa perlu inspect

• Siapa perlu hadir

• Code & standard mana ikut

• Acceptance criteria

• Form/rekod yang perlu disediakan

  
  

Ringkasnya: ITP = pelan perjalanan quality satu projek.

Content Required in an ITP

Header / Project Information

• Project Name

• Project Number / Contract Number

• Package / System / Area

• Discipline (Piping / Welding / Mechanical / Civil / Coating)

• Document Title (Inspection & Test Plan)

• Document Number

• Revision No. & Revision Date

• Prepared / Checked / Approved By

• Company Name & Client Name

• Project Location

  
  

Ini memang standard EPC, vendor & fabricator.

Main ITP Table — Struktur Sebenar

• Activity / Process

• Reference Documents

• Code & Standard

• Acceptance Criteria

• Inspection / Test Method

• Inspection Level (H / W / M(S) / R)

• Responsibility (Contractor / TPI / Client)

• Records / Forms Required

• Remarks (jika perlu)

  
  

Setiap baris adalah satu checkpoint quality.

Understanding the ITP Codes

Maksud H / W / M(S) / R

• H – Hold Point: Kerja mesti berhenti sehingga Client release. Checkpoint paling kritikal.

• W – Witness Point: Client/QC diberi notis. Jika tak hadir ikut notis, kerja boleh diteruskan tetapi evidence wajib lengkap.

• M(S) – Monitoring / Surveillance: Spot check / pemantauan. Kerja tak perlu berhenti.

• R – Review: Semakan dokumen: MRIR, WPS, WQT, MTC, NDT report, drawing, dll.

  
  

Common Forms/Records Related to ITP

Material Receiving

• MRIR

• MTC/MTR

• Incoming checklist

  
  

Welding & Piping

• Fit-up report

• In-process & final VT

• Weld summary

• WQT record

• NDT request & reports

  
  

Hydro / Pneumatic Testing

• Hydro/pneumatic test report

• Test pack

  
  

Coating

• Surface prep checklist

• DFT report

• Holiday test report

  
  

Mechanical

• Alignment record

• Torque/tension report

• Installation checklist

  
  

Hand Over

• MDR

• As-built

• Final inspection report

• Punch list

  
  

Rule utama: Jika client bagi template, ikut 100%. Jika tidak, format standard seperti ini digunakan.

Common Mistakes to Avoid

Kesilapan Yang Biasa Terjadi

❌ Tak baca ITP sebelum mula kerja

❌ Tak faham maksud H/W/M/R

❌ Acceptance criteria ikut “agak-agak”

❌ Rekod tak lengkap

❌ Panik bila client dah sampai

Inspector power ialah yang faham logik setiap checkpoint, bukan yang hanya hafal.

Conclusion

In conclusion, understanding and implementing an Inspection & Test Plan (ITP) is crucial for ensuring quality in construction projects. By following the guidelines and avoiding common mistakes, we can enhance our inspection processes. Remember, the key to success lies in thorough preparation and clear communication.

Let's strive for excellence in our projects! 🌟
