Drawing Standards Audit

This is not a review of what the drawings show. It is a sweep for the things that make a set usable: that a reference lands somewhere, that the index matches the set, that a symbol means one thing. A set can be technically right and still generate a correction letter and forty RFIs because nobody could find anything.

Workflow

Step 1. Establish what the standard is

Ask, in one message:

1. Is there an office or project standard? Paste or point at it.
2. What is the set, and how is it supplied?
3. What phase, and is this a pre-issue check or a general audit?
4. Have consultants' sheets been included, and are they held to the same standard?
5. Is there a previous revision to compare against?

Where no standard exists, say plainly that the audit will check internal consistency and nothing else. That is still worth doing and it is a different claim.

Step 2. Index and sheet integrity

• Every sheet in the index exists in the set.
• Every sheet in the set appears in the index.
• Sheet numbering follows a sequence, with gaps reported.
• Sheet titles in the index match the titles on the sheets.
• Consultants' sheets are present and in the sequence the index claims.

This is first because everything after depends on knowing what the set is.

Step 3. References, in both directions

The most valuable pass, and the most tedious.

Reference	On sheet	Points to	Exists?	Kind

Check:

• Every detail, section, elevation and enlarged plan callout lands on a drawing that exists, on the sheet it names, with the number it names.
• Every drawing on a sheet is referenced from somewhere. An unreferenced detail is either an orphan or a missing callout.
• Every schedule reference resolves.
• Every reference to a specification section names a section that exists in the book.

Report broken references by kind and by frequency. Thirty broken references all pointing at one sheet is one problem.

Step 4. Title block and issue data

Across every sheet: project name, number, address, north point, scale, date, revision, drawn and checked, seal block, and whatever else your standard names. Report by field rather than by sheet, so a field missing on forty sheets reads as one finding.

Check the revision data against the revision history and against any cloud on the sheet. A clouded change with no revision entry, or the reverse, is a finding.

Step 5. Symbols, abbreviations, and one-word-one-meaning

• Every symbol used appears in the legend.
• Every symbol in the legend is used.
• Every abbreviation used appears in the abbreviation list.
• The same term is used for the same thing throughout. Two words for one thing, or one word for two, both get reported.
• Wall types, door marks, room numbers and finish codes follow one convention.

Step 6. Information appearing twice

Find anything stated in two places and check the two agree: a dimension on a plan and on a detail, an area on a plan and on a schedule, a rating in a legend and in a schedule, a note on a sheet and in the specification.

Where the two disagree, report both values and neither as correct. Where the two agree, report the duplication anyway, because duplicated information will eventually disagree.

Step 7. Report by frequency

Finding	Count	Systematic or isolated	Where

Order by count. Then:

• Systematic findings first, with the likely cause if one is visible: a template problem, a missing standard, a sheet set up by a different hand.
• Isolated findings as a list.
• What could not be audited, and why: a set supplied as images, a standard not supplied, consultants' sheets missing.

Step 8. Save, if asked

Ask whether to write the audit to a file and where. CSV where it becomes a task list.

Rules

• Never supply a standard. Yours, the project's, or internal consistency only.
• Check references in both directions.
• Report by field and by frequency, never sheet by sheet.
• Where two sources disagree, report both and rule on neither.
• Report duplicated information even when it agrees.
• Say plainly what could not be audited.
• Never fix anything.

Anti-patterns

• Reviewing what the drawings show. Different skill, different question.
• Listing four hundred findings sheet by sheet, which nobody acts on.
• Checking that callouts resolve without checking for unreferenced drawings.
• Auditing against a remembered office standard.
• Treating a missing title block field on every sheet as forty findings.
• Deciding which of two disagreeing dimensions is right.
• Skipping consultants' sheets because they are somebody else's.
