Vendor Documentation in I&C Projects – Why RFD Matters
In instrumentation and control projects, smooth execution depends heavily on timely and complete vendor documentation.
What is RFD?
RFD in simple terms: a shared list of documents that MUST come from the vendor, linked to project milestones.
No guesswork. No “I thought you were doing that”.
It ensures:
No missing documents
Clear responsibilities
Proper tracking with timelines
Typical Vendor Documents
For a typical package, you need at least:
Instrument datasheets
Wiring / interconnection and loop drawings
Cause & effect inputs and shutdown interfaces
Panel GA, I/O list, communication/interface details
Certificates, manuals, and tools/consumables list
Key Stage: Kick-off Meeting
This is where you win or lose the project control.
Must clarify:
Battery limits and responsibilities
Exact document list and revisions
Issue sequence (Engineering, FAT, SAT requirements)
Simple Tracking Method
For beginners, keep it simple:
One register (Excel is enough)
Document code
Title
Revision
Due date
Status
Not received
Under review
Approved
Review it with the vendor in every progress meeting
Why RFD is Critical
If you get RFD alignment early:
Avoid late surprises
Prevent engineering delays
Reduce rework and claim discussions
Without it:
Delays
Missing inputs
Commercial disputes
