What is Supplier Data Management?

Supplier data management is the process of defining, collecting, validating, and integrating the technical data and documentation delivered by equipment suppliers and subcontractors during a capital project. It covers everything from manufacturer data reports and operation and maintenance manuals to structured equipment attribute data and inspection certificates.

Supplier data is the raw material of the project handover package. The quality of supplier data delivery is the single largest determinant of handover completeness and accuracy — and one of the most consistently underestimated risks in capital project information management.

What is a Supplier Document Requirements List (SDRL)?

An SDRL (Supplier Document Requirements List) is the contract document that specifies which documents and data a supplier must deliver, in what format, at which milestones, and to what quality standard. A well-written SDRL is the foundation of effective supplier data management — it removes ambiguity about what is expected and creates the contractual basis for rejecting non-compliant submissions.

Effective SDRLs for modern digital projects specify not just document types and formats, but also structured data requirements — for example, CFIHOS attribute data for each equipment class, in a defined template format.

Common supplier data quality problems and their impact

• Wrong equipment tag numbers: Supplier submits documentation against their own internal references rather than the project tag numbers — making it impossible to link documents to the correct items in the owner's systems
• Missing or incomplete O&M manuals: Manuals submitted without required content (e.g., missing spare parts lists, maintenance procedures not matching installed configuration)
• Data submitted in non-standard formats: Attribute data provided in PDF rather than structured templates — requiring manual extraction
• Late submission: Documentation not available at the time of mechanical completion or handover, delaying system population
• Incorrect revision management: Suppliers submitting updated data without revision identifiers, making it impossible to track what has changed

Structured supplier data: CFIHOS and data templates

Leading owner-operators increasingly require suppliers to submit structured equipment attribute data — not just PDF datasheets — conforming to CFIHOS or owner-defined data templates. This enables automated import of supplier data into the owner's asset management systems, eliminating manual data entry and its associated errors.

This requires suppliers to have the capability to populate structured data templates, and EPCs to manage the supplier data submission and validation workflow as a formal project process — not an administrative afterthought.

How to manage supplier data effectively on large EPC projects

• Define data requirements in SDRL at contract award, not at the start of detailed engineering
• Provide suppliers with standard templates and clear submission instructions from the outset
• Validate submissions against requirements early — reject and return non-compliant submissions rather than accepting them and hoping to fix them later
• Track submission and acceptance status by supplier, document type, and equipment tag through a centralised system
• Link accepted documentation to the correct equipment tags in the Master Tag Register as part of the acceptance process

What Is a Vendor Data Book (VDB)?

A Vendor Data Book (VDB) — also known as a Manufacturing Record Book (MRB) or Quality Dossier — is the documentation package an individual equipment supplier delivers at the end of a purchase order. It is the supplier's delivery against the SDRL: typically containing material test reports, factory acceptance test certificates, as-built drawings, inspection records, and declarations of conformity for that specific piece of equipment.

The VDB sits one level below the project handover package. Where the Document Handover Package covers the full EPC-to-owner-operator transfer at project completion, the VDB is a supplier-to-EPC deliverable — one per vendor scope. Validating VDB completeness against the SDRL for every purchase order is a core task in supplier data management on large capital projects.

Frequently asked questions about supplier data management

Who is responsible for supplier data management on a capital project?
Formally, the EPC, as the contractor responsible for the handover package. In practice, a dedicated information management or document control function within the EPC manages the SDRL, submission tracking, and validation workflow. Owner-operators who actively participate in SDRL definition and data validation during the project consistently achieve better handover quality.

What happens when supplier data is missing at handover?
Incomplete supplier data is typically managed through a handover punch list: outstanding items are tracked, and milestone payment or final acceptance may be withheld until outstanding data is received and accepted. In practice, many operators accept handover with outstanding supplier data and pursue resolution post-handover — a pragmatic but risk-bearing approach.

What is the difference between an SDRL and a Vendor Data Book (VDB)?

The SDRL is the contractual specification of what a supplier must deliver — document types, formats, and submission milestones. The VDB is the supplier's compiled delivery against that SDRL for a specific purchase order, assembled at the end of the vendor scope. The SDRL is set at contract award; the VDB is submitted at mechanical completion or handover.
