Civil Engineering Drawing numbering

Does anyone know of a generally accepted standard for numbering civil drawings? Any info would be appreciated.

Thanks

Wow, i have seen more schemes in my 40 years. However there are a few concepts to keep in mind on large jobs.

Keep flexibility in the scheme. That is room in the numbering scheme to add draiwngs without getting long, complex numbers. Each structure has a 100 series, say, so there is a possibility of 99 drawings for that structure. Its really OK to not have all the numbers available in the drawing index.

Prefix the number with a letter. S for structural; A for architectural, P for plumbing, etc.

Its much better to have to improvise latter in the project than early on. Keep the 'improv' for as late in the project as possible.

And, by all means, :::::: KISS.

I agree with keeping flexibility in the scheme. It is a pain to add/remove/renumber dwgs, so the fewer you have to do, the better. Decide on your groupings/ sheet-type order, then leave room for expansion everywhere.

Another tip - use "sub-letters."
Decide on the subletters up front, and use the same ones for sheets of the same category, i.e. all plan sheets are subletter A, all Profile sheets are subletter B, all details are subletter C, etc.
For instance, if your naming convention for Piping dwgs is usually something like projnumP-001 to projnumP-100, consider changing numbering to something like this: projnumPA-00 for Piping Plan sheets, then projnumPB-001 for Piping Profile sheets, then projnumPC-001 for Piping Detail sheets, etc. That way when you have to add/remove/reorder sheets, you can just deal with that series of the Piping Sheets, rather than renumbering 99 sheets just to add a Sheet 2...
Using the subletters, then Civil Detail sheets would start with projnumCC-001, Mech Detail sheets would be projnumMC-001, etc.
For the subletters, either pick something you think makes some sense, or just go for alphabetic order based on the order of the sheet types. If you go alphabetic, then maybe use every 3rd or 4th letter initially so you can add a subletter in the middle later if you need to.

Flexibility is definitely key.
And regardless of National CAD Standards, I think the sheet name should be in the CAD filename if possible. Otherwise, it just gets confusing if you have a lot of sheets.

 

1, 2, 3, 4, 5, 6, 7, 8, 9, 10,.....you get the idea....

drawings? Any info would be appreciated.
