WHRS PACKAGE - THAI OIL
Our objective was to develop comprehensive Inspection and Test Plans (ITPs) and issue final indexes for complex, multidisciplinary client projects. This required translating contractual specifications, engineering deliverables, applicable standards, and quality requirements into clearly defined inspection activities, acceptance criteria, hold points, and verification records. Close coordination among engineering, quality, construction, and document control teams ensured that requirements remained aligned as designs evolved and stakeholder comments were resolved. Final indexes were then reconciled against approved deliverables and supporting records to provide a complete, traceable basis for client review and project handover.
THE CHALLENGE
The principal challenge in developing ITPs and issuing final indexes was managing the volume and interdependence of requirements across multiple disciplines. Contractual specifications, design revisions, inspection criteria, and client comments often changed at different stages, making it difficult to maintain consistent hold points, acceptance criteria, and document references. Final index preparation added the challenge of reconciling approved deliverables with inspection records, revisions, and closeout documentation. Any gaps or inconsistencies could delay approval and handover, so resolving them required sustained coordination across engineering, quality, construction, and document control teams.

OUR APPROACH
Our approach combined requirements mapping, multidisciplinary review, and controlled document reconciliation to establish a reliable path from ITP development through final index issuance. We first examined contractual obligations, technical specifications, approved drawings, and applicable standards to identify inspection activities, acceptance criteria, witness and hold points, and the records needed to demonstrate compliance. These requirements were then incorporated into discipline-specific ITPs and reviewed with engineering, quality, construction, and client representatives to resolve gaps, overlapping responsibilities, and conflicting interpretations before approval.
As the project progressed, we maintained revision control over the ITPs and tracked changes in design, inspection scope, and client requirements against the associated verification records. For final index issuance, we reconciled the document register with approved deliverables, confirmed revision status and document references, and checked that outstanding comments and required closeout records had been addressed. This sequence created a traceable link between contractual requirements, executed inspections, and the final documentation submitted for handover.
