Drawing QA/QC and Review
What the module checks, what it cannot check, and how to work through a set of findings.
Drawing QA/QC reviews a drawing set the way a senior reviewer would: sheet by sheet for what is wrong on the page, then across the set for what is only wrong in company.
Every check runs from the PDF. No model is required.
Scope
Review is sheet-level. Bimiq reads what is drawn and annotated on each sheet, and compares sheets against each other. It does not open your model, and it does not know anything the drawings do not show, unless you connect a model separately for reconciliation.
The check families
On the sheet
| Rule | Finding | Severity |
|---|---|---|
| A1 | Sheet number missing from the title block | High |
| A2 | Sheet title missing | Medium |
| A3 | Scale not stated on a scaled sheet | Medium |
| B2 | Grid line has no label | Medium |
| B3 | Tag has no label | Low |
| C1 | Dimension has no value | Low |
Across the set
| Rule | Finding | Severity |
|---|---|---|
| D1 | A callout points to a sheet that is not in the set | High |
| D3 | The same sheet number appears twice | High |
| XD1 | Grid labels disagree between disciplines | Low |
D1 is the check that most repays the run. A detail callout pointing at a sheet nobody drew is invisible on the sheet it sits on, and it surfaces on site as an RFI.
Against your standards
Separately from the built-in checks, each sheet is checked against the rules extracted from the code documents on the project: your firm's drawing standard, the building code for the jurisdiction, or both.
Every project starts with the Bimiq Built-in QA/QC Standard, a generic drafting and coordination standard, so this runs before you have uploaded anything of your own. Replace it through Standards when you have your firm's real one. See Document types.
Working through findings
Open the set, work down the findings list, and check each one against the highlighted region on the sheet before acting.
Sort by severity when you are trying to get a set out of the door. Read the whole list when you are trying to judge the quality of a set you have just received from a consultant.
Findings you dismiss stay dismissed. A finding is a claim about the drawing, not a task, and dismissing it is a legitimate answer.
Deep XD
Deep XD is a second, heavier pass focused on cross-discipline coordination between sheets in the set. Run it when you have several disciplines in one set and want the coordination read rather than the compliance read.
Reconcile with model
Reconcile with model compares the sheets you uploaded against the live Revit model. It is on-demand, needs the Bridge running, and needs the model open.
It catches the drift between a model and the sheets that were published from it:
R1, a sheet in the set that no longer matches its view in the modelT1, title block data that disagrees with the modelG1, grids that disagree between the sheet and the model
This is the check that answers "are these drawings still the model?", which no amount of reading the PDF can settle.
What it will not catch
Be clear about the boundary, because acting on a false sense of coverage is worse than not running it.
- It does not know your design intent. A wall in the wrong place is only a finding if the drawing contradicts itself or contradicts a rule.
- It reads what is legible. Faint, rotated, or badly scanned annotation produces both misses and false positives.
- It is sheet-level, so anything that depends on the model geometry needs reconciliation.
- Findings are proposals. Nothing is corrected, issued or sent on your behalf.
Cost
Drawing checks are metered per sheet, so a 400-sheet set costs proportionally more than a 40-sheet one. Splitting the PDF is free; only Analyze is charged. See How credits work.
