8. What’s SATIP? What’s the information we can get from it?
Saudi Aramco Typical Inspection Plan: ITP is a document which gives a summary about how the quality of a particular element of the construction works is to be managed. It’s a part of the project Quality Management System and PQP.
As a minimum, each ITP shall include the following information:
- Process description.

- Notification requirements for Requests For Inspections (RFI) (minimum 24 hours for site work, 48 hours for weekend inspections, except when SAUDI ARAMCO personnel will require special qualifications.).
- Responsibilities.
- Applicable procedures.
- Acceptance criteria.
- Percentage of tests to be done (including increased inspection levels when performance requirements are not met.).
- Verifying documents.
- Review, Witness and Hold points.
9. What’s SAEP-1150, 1151, 1160 and SEAP-381 In detail?
SAEP-1150: (Inspection Coverage on Projects).
- This procedure defines the responsibilities and activities of the Inspection Department (ID) on all projects managed by Project Management including Third Party projects as per SAEP-50 and SAEP-21.
- This procedure covers only quality management system activities during the project life cycle.
SAEP-1151: (Inspection Requirements for Contractor Procured Materials and Equipment).
This document, together with the purchase order and appropriate project specifications define the minimum mandatory inspection requirements for project Contractor materials and equipment.
SAEP-1160: (Tracking and Reporting of Welding, NDT and Pressure Testing for Capital Projects).
This document establishes minimum requirements and responsibilities for the tracking and reporting of production welding (full penetration grove welds), welder performance, NDE tracking and pressure test verification associated with In-Kingdom construction activities at Saudi Aramco facilities.
SEAP-381: (Project Quality Issues Escalation Process).
This Procedure establishes instructions for escalation of unresolved quality issues in Saudi Aramco projects including delinquent quality concern notifications.
10. How Contractor INCR escalated to SANCR?
If it’s not closed within the ACD it will escalate to LBE if still no corrective action and not closed yet, it will escalate to SANCR.
Or if it’s not closed within 90 days from the initiation date.
11. What’s the violations degree?
MAJOR (If any one of the following applies).
Violations of company standards including GIs that put the quality and integrity of the facility including its workers and equipment at risk.
Actions that violate the Corporate values by submitting forged items & counterfeit materials.
MODERATE (If any one of the following applies).
Any violation to MSAER, project specifications and approved IFC drawings that if the next phase of work (critical path) is continued without correcting the violation, the structural integrity of the next phase will be jeopardized. Such violation if not corrected in a timely manner will lead to more severe damage or complexity.
Any violation to Schedule Q.
MINOR (If any one of the following applies).
Any violation to SAES, SAMSS, project specifications and approved IFC
drawings but the next phase of work is not dependent on the correction of
the violation.
12. What are Contents of WPS, PQR?

13. What’s SAEP-324? Levels of WRR in detail?
SEAP-324: (Certification Review and Registration of Project Welders).
This Engineering Procedure specifies the minimum requirements for certification review and registration of contractor welders working on In Kingdom construction and fabrication projects.

Contract Welders and Welder Operators performance criteria to meet 0.2% Linear and 5% joint basis, with linear being the over-riding factor. From the performance data the welders shall be categorized from the linear WRR criteria as follows:
A. 0 – 0.2% Level A
B. >0.2% – 0.4% Level B
C. >0.4% – 0.5% Level C
