Specification to drawing consistency check
Reconciling what the specification requires with what the drawings and schedules show, item by item, with every mismatch traced to its clause and sheet.
Specifications and drawings are written by different people, at different times, and go out of step the moment either one changes. The specification says one thing about a product, the drawings show another, and the schedule shows a third. The check is a comparison every design manager knows they should run and few have time to, so it happens instead at tender queries, at submittal review or on site. Structured knowledge lets a team run the comparison across the whole set, with every mismatch traced to its clause and drawing, and keep the design manager on the decisions.
What the workflow involves today
Pick a package or a system and list every specification clause that applies to it.
Find each element on the plans, sections, details and schedules and note what they show: product, size, rating, finish, location.
Compare clause by clause and drawing by drawing, and record each mismatch with both references.
Check whether an RFI response, an instruction or a re-issue has already resolved the mismatch.
Decide which document is right, then issue the revised drawing or specification clause, or raise a TQ if the answer is not yours to give.
Repeat for the next package, usually only for the packages that have already caused a problem.
Where generic AI tools fail
General-purpose tools can read a specification, and they can read a drawing after a fashion, but they cannot hold both in view and compare them, because they have no way of knowing that a clause in the ironmongery section and a row in the door schedule are about the same door. Ask for a consistency check and you get a summary of each document with a sentence saying they appear broadly aligned, which is not a check.
Even where a tool finds a mismatch, it cannot tell you whether it still matters. An RFI response or an instruction may have resolved it weeks ago. Without the rest of the project record the tool reports stale conflicts alongside live ones, and the design manager has to re-check every one, which is the work the tool was supposed to remove.
What changes with structured knowledge
When the project record is structured knowledge rather than a set of separate files, the specification clause and the drawing element that describe the same thing are already connected, so the comparison runs across the whole set rather than one package at a time.
What the design manager receives is a list of mismatches, each with the clause, the drawing and the schedule row it was found on, the values the documents disagree about, and a note where an RFI response or an instruction has already resolved it. The list is grouped by package so that the right person sees the right items.
The design manager reads the live mismatches, decides which document is wrong, and issues the change. Time goes on the decisions, and every change carries the references that justify it.

This workflow reads specifications, drawings and schedules together and leans on RFI responses and instructions to know which mismatches are already resolved. It sits alongside drawing coordination review, which compares drawings with each other, and submittal review, which uses the same clause-to-drawing relationships.
Does it check schedules as well as drawings?
How does it know a mismatch has already been resolved?
How do we see it on our own drawings and specification?
