It is important sheeting numbering is set up early in a project so people know what numbers to use as they create sheets.
Although it is a trivial exercise in Revit to renumber and rename sheets (cross referencing automatically updates) it is bad professional practice to change the identifying numbers of drawings already issued to others.
It is also poor practice to issue drawings to anyone outside of the office without an identifying number. It is expected, and a legal requirement, that any thing issued is filed and can be retrieved on request.
The actual number system used is not that important, what is important is that there is one.
Below are suggestions for a quality numbering system. Always confer with the client and builder (if possible) to ensure they do not have their own requirements.
SHEET NUMBERING FOR TITLEBLOCKS
General format is:
prefix - disciplineNumber
e.g.
CD-A103
SHEET NUMBER PREFIX
Generally Sheet number prefix is the stage of the project:
But may also be for particular types of drawings:
The prefix may also contain letters describing a part of a project.
But should still be combined with the stage prefix.
e.g. CD-B1-A103
In Revit we normally place the sheet number prefix in a custom shared parameter separate the the sheet number.
This is so the prefix is not included in cross reference bubble (elevations, sections, call outs), which means these references can be kept smaller.
DISCIPLINE
Usually A, or AR, for Architecture.
SHEET NUMBER ORDER
Drawings sets are broken into sets of Series.
For small projects drop the last digit (e.g. 1300-1399 becomes 130-139).
SK
PR
Sketch
Presentation
SKETCHES
Sketches are drawings issued for particular purposes that are NOT part of the main documentation set.
They may be issued to assist discussion of design alternatives, coordination problems or to accompany RFIs.
By their unpredictable nature it is not possible to pre-establish drawing series or sequences. Therefore sketches are just numbered sequentially.
It is normal practice to set-up a spreadsheet where sketch numbers are recorded as they are created to ensure the same number is not used multiple times.
Revit requires all sheet numbers to be unique so sketches need to be identified within their sheet number.
To achieve this sketches can be part of a number series (e.g. 8000 series), or have the number prefixed with SK- or similar (e.g. SK-0001).
The method used will depend on whether you are limited or not in what you can do with drawing prefixes.
If you can place SK (or similar) adjacent to the sheet number include it as part of the sheet number, even if there is a prefix (italic is sheet number):
e.g.
SK-0001
or
AR- SK-0001
If not use a drawing number series:
e.g.
MPRB-SK-AR- 80001
