- Organize sheets according to disciplines
- Organize sheets according to facilities
Organizing sheets according to disciplines is typical for projects with a single facility. However, when two or more facilities are needed it is often advantageous to organize the sheets into subsets containing each discipline's sheets for a specific facility. Organizing sheets according to facilities helps save time because information for each facility is kept together instead of being scattered throughout the drawing set.
Sheets in the drawing set can be organized according to each facility as follows: First, assign a letter to each facility, usually starting with A, followed by B, and so on. Then, assign the same letter as a suffix to the sheet numbers that make up the subset for each facility. The sheets within each facility subset are organized according to the NCS discipline hierarchy.
The following list of sheets is an example for projects containing more than one facility:
OFFICE BUILDING LIST OF SHEETS (Buildng "A")
S-101A: Office Building Structural Foundation Plan
A-101A: Office Building Floor Plan
A-201A: Office Building Exterior Elevations
A-401A: Office Building Enlarged Plans and Elevations
P-101A: Office Building - Waste & Vent Plan
P-103A: Office Building - Domestic Water Plan
M-101A: Office Building - Mechanical HVAC Plan Area 1
E-101A: Office Building Power Plan Area 1
E-103A: Office Building Electrical Lighting Plan Area 1
E-601A: Office Building One-Line Diagram & Panelboard

One challenge to organizing drawing sets according to facilities is to find a place for sheets that are not specific to a single facility. These may include: regulatory information, site plans, phasing plans, common details, and schedules. Sheets like site plans and phasing plans should usually be located ahead of the subsets for facilities because they contain information and overall views that apply to entire project. Sheets containing sections, details and schedules that are shared by more than one facility should be located after the facility subsets and are organized according to NCS discipline hierarchy.
Tips for assigning letters to each facility: Avoid the letters I and O because they will get confused with numbers when used as the suffix of the sheet number (i.e., A-101O, S-501I). When possible, assign facility letters according to the actual name of the facility - such as S for storage buildings, P for pump stations, etc., because it will make it more intuitive for users to associate the sheets to the facility.
For an example of a list of sheets for projects with multiple facilities, please send me an email and I will provide one to you (crgreen@wilsonco.com).

Although this solution does segregate the buildings, it does NOT easily help in organizing the drawing index. Your plan still mixes up the buildings because the drawings will put all of the A- together then all of the S- together etc. On page UDS-01.18 it allows for an optional prefix. Could we instead of using S-101 use A-S-101 where A is the first building or work area on my site?
A-S-101 does not work because it is not NCS compliant. The page number azerarden is referring to (UDS-01.18) is for file naming - not sheet numbering. User defined prefixes for sheet numbering are not allowed by the NCS
The sample drawing list I've provided keeps all the disciplines for each building together (that was the task at hand) - and a user-defined PREFIX assigned to each building type is the most efficient and intuitive way to achieve that.
I would like to point out that your solution has two problems. First it is also NOT NCS compliant. (You forgot the hyphen)UDS-01.14. Second you have not really made it easy to sort the set per workarea with placing the suffix on the end. The only way around this is to add dual sheet numbering and put 1 of 200 etc. That way we can alphabetize the drawing set easily by workarea. This also has problems because you need to make sure NOT to duplicate the base numbering system from NCS. We could write up a ballot item and get it voted on next year in the NCS5 ballot. That way we could have this fixed by March of 2011.
According to UDS-01.14, the suffix "may be comprised of three user-defined designators." Even though hyphens are used as the first designator in each of the examples, they are not mandatory. We need to clear this up in NCS v5.0 by providing an example without a hyphen - thanks for helping us identify that clarification.
I am not quite sure I am following your point with regard to "sort the set." The list of sheets on Sheet G-001 will identify sheet order within the drawing set. Prior to final printing, I strongly recommend including 1 of 200, 2 of 200, etc. in the Sheet Identificaton Block for all drawing sets because it is very helpful to organize the set and establish the total sheet count for printing - this feature is already in the NCS (UDS-02.16).
