Project Quality Management System for Capital Projects & EPCM Programs

What is a Project Quality Management System?

A Project Quality Management System (PQMS) is the project-specific framework that plans, executes and evidences every quality activity on a capital project — from ITPs and third-party inspection to non-conformance control and the final turnover data-book.

Unlike a Corporate QMS, which persists across the enterprise, a PQMS is scoped to the contract, standards and lifecycle of one project. Its job is to make sure the completed asset can be handed over with a full, auditable trail of evidence — and that nothing that shouldn’t be there ever gets built in.

How Jags Assurance delivers it end-to-end

We mobilise before procurement: writing the Project Quality Plan, issuing ITPs, qualifying vendors, and standing up NCR and document workflows. Through fabrication and construction, our independent inspectors and lead auditors carry the plan into the shop and onto site. At handover, we deliver a certified data-book with every hold point traceable to a signed record.

Inspection test plans for modular fabrication and skid-built units

Modular and skid-built fabrication is a major driver of our PQMS work. We write inspection test plans (ITPs) that map hold, witness, review and monitor points to module drawings, weld procedure specifications and NDE plans before the first cut is made, then carry those ITPs through shop surveillance, pre-shipment release and site receiving.

Modular delivery compresses the window in which a defect can be economically corrected. Once a pipe rack, e-house or process skid leaves the shop, access to welds, supports and internals is largely gone. Our modular ITPs therefore front-load verification into the fabrication yard: material traceability and mill-cert review at receiving, fit-up and dimensional control against the module datum, weld mapping with NDE coverage per joint class, coating and insulation hold points, and electrical/instrument loop checks completed at the skid rather than at site.

Each module or skid carries its own ITP package and turnover dossier, so the completed unit ships with dimensional records, weld and NDE traceability, pressure and leak-test certificates, and a closed punch list. Multi-yard programmes are governed by a common ITP template with yard-specific annexes, keeping acceptance criteria identical across fabricators and letting the site team receive, set and tie in modules without re-inspecting work that was already verified and evidenced upstream.

• Material receiving: Mill certs verified to EN 10204 3.1/3.2, heat-number traceability to the module BOM.
• Fit-up & dimensional: Datum-referenced survey against module drawings before closure; tolerances agreed with the site set-out team.
• Welding & NDE: WPS/PQR and welder qualification to ASME IX; joint-class NDE coverage to ASME B31.3 or AWS D1.1, with RT/UT review as a hold point.
• Pressure & leak test: Witnessed hydro/pneumatic testing with signed test packs before insulation or coating.
• Coating & insulation: Surface prep and DFT checks to SSPC/NACE, held open until the substrate inspection is signed.
• Loop & functional checks: Instrument loop and E-house functional testing completed at the yard, not deferred to site.
• Pre-shipment release: Final walkdown, punch-list closure and turnover dossier issued before the module leaves the yard.

New to ITPs? Start with what an inspection & test plan is, with a worked example and template columns. Writing your own? Our step-by-step guide on how to prepare an inspection & test plan (ITP) walks through hold points, witness points, acceptance criteria and clause references. The records those hold points generate are compiled into the manufacturing record book issued at turnover, and the whole structure is governed by the project quality management plan.
