Estimate PLC scope from a P&ID set during bid.

When a controls integrator gets an RFP with P&IDs attached, the estimator has 48 hours to produce an I/O count, card sizing, marshalling cabinet plan, and a bid number that survives senior review.

Workflow.

01
Upload the bid drawing set
Drop the entire P&ID PDF set into a workspace. You can start reviewing the first pages while the rest of the set is still coming through.
02
Review the I/O list with signal classification
Every instrument carries a control-system signal class, AI, AO, DI, DO regardless of which tag standard the drawing was authored in. Filter by class and export the count for card sizing. The SIS instruments are separated into their own subset so they route to a separate logic solver and cabinet.
03
Apply scope assumptions and export the bid package
Strip out tags marked future or vendor-supplied, set spare capacity assumptions, and export both the I/O list and a card-sizing summary as Excel for the bid response.

What you get.

I/O count by signal class
Card-sizing rollup for Siemens, Rockwell, and generic PLC families
Marshalling cabinet sizing suggestion based on terminal density
Excel bid package with audit trail of which page each tag came from

FAQ.

01How complete is the I/O count from an early bid drawing set.
It depends on the state of the drawings. A clean CAD-exported set reads more completely than a faded scan, and on a rough scan the count is a starting point you confirm against the sheets. Either way you get a structured I/O list you review and adjust before you lock the bid number, not a black-box figure you have to take on trust.
02Can I import the bid I/O list back as the project I/O list once we win.
Yes. The Excel and JSON exports carry tag, signal class, location, and source page metadata. Once contract is awarded you can promote the bid workspace to a project workspace and continue from there without re-typing.
