ISSUE 04 · REV C The Transom Set

Send the sheet number, the figure as drawn with its unit, and a link to a specific document that contradicts it; a sourced contradiction changes the sheet and moves its revision.

Mark-ups: how to argue with a figure on this set

rev A

issue 04rev Adrawn by The Transom Set (a named set, not a person)

A four-step flow showing how a mark-up is handled
A source that will not open changes nothing. Not to scale.
A table of the four fields a mark-up should contain
A change and a record are different outcomes.
A checklist of four edits this set will not make
No sheet is reworded to look fresher.

What to send

  1. The sheet number and its address. One sheet per message; do not batch.
  2. The figure you think is wrong, quoted exactly as the sheet draws it, with its unit.
  3. The document that contradicts it, as a link to a specific publication — not a home page and not a search result.
  4. Whether you want the figure changed or the disagreement recorded. Both are useful and they are different edits.

What happens next

If the document is specific and it contradicts the sheet, the figure changes, the revision letter moves and the issue date moves. If the documents genuinely disagree with each other, the disagreement is recorded rather than resolved, and it is recorded as a revision with the two positions side by side and the dates on both. If the document cannot be opened, nothing changes and you are told why.

What will not happen

  • No sheet will be changed to a figure that has no document behind it, however plausible it is.
  • No definition will be reworded to look fresh.
  • No product will be recommended, in either direction.
  • No mark-up will be applied anonymously on a sheet about somebody's building.

There is no form on this set and no analytics on this set, so the mailbox is the only channel. If the mailbox is not live yet, the set is not deployed yet and this sheet is the last thing to fix.

Documents this sheet is drawn from

  3. 3Thresholds [ADA Standards Section 404.2.5] - maximum height and bevel requirementssupports the maximum threshold height and bevel requirement quoted on that sheet

Each line points at one specific document, with its own title as the link text. No line is a home page and no line is a search result.
