Identify one physical opening across drawings
Build a record around the physical opening's building, level and wall location. Attach the corresponding plan, elevation and schedule references to that record. Multiple appearances are useful checks on one identity; they are not automatically additional quantities.
| Observation | Location evidence | Reconciled identity | Added quantity |
|---|---|---|---|
| W01 on plan | Main building, ground level, south wall | W01 | 1 |
| W01 on elevation | Same level, wall and location | W01 | 0 |
| W01 in schedule | Same mark and applicable drawing issue | W01 | 0 |
The three observations above produce one reconciled opening. If the wall, level or revision does not agree, record the conflict before deciding whether the items match. A repeated label by itself is insufficient evidence for a merge.
SolidTakeoff's counting workflow describes counting by type and cross-checking the schedule. The table here adds our own explicit record of which observations contribute a new physical quantity.
Separate repeated types from unique openings
A type groups openings that share a specification. It does not necessarily represent one occurrence. A grouped schedule with two type rows might describe five physical units. Count occurrences or use the stated quantities, according to the project's convention.
| Type | Physical opening marks | Quantity |
|---|---|---|
| T01 | A01, A02, A03 | 3 |
| T02 | A04, A05 | 2 |
| Total | Five distinct occurrences | 5 |
Do not add the type rows to the physical rows: three plus two is five, not seven. Do not assume two openings are duplicates because they have the same dimensions. These five-opening teaching records are independent of the eight-opening synthetic house PDF.
Use the mark and type legend to establish which convention your source uses before selecting a counting method.
Resolve uncertain identities
Keep an uncertain match on a review list. Record the candidate marks, source pages, building or level, reason for doubt and person responsible for clarification. Do not silently merge two observations when one could describe a second opening.
Typical checks include repeated floor layouts, similar elevations on different buildings, existing versus proposed work and superseded revisions. Mark the scope before adding quantities. An alternate design is not automatically part of the base quantity.
The AI output review workflow applies the same evidence standard to generated proposals. This guide describes a manual reconciliation method; it does not promise automatic deduplication.
Reconcile placed and unresolved counts
Compare the reviewed physical-opening list with the workspace's placed openings, unresolved proposals, context-only elements and schedule entries without an assigned opening. Those are different groups. An unresolved proposal may be an additional opening or another observation of an existing one; its status must be checked.
For the synthetic six-sheet house, the stated scope is six windows, one entrance door and one sliding door: eight distinct openings. That is the source's expected inventory, not a count to force onto every imported result.
Before handoff, explain outstanding identities alongside the preliminary quantity. Do not add placed and unresolved figures into an apparently approved total. Follow the PDF takeoff sequence to connect the source review, model and exported schedule.
