CSI, together with other organizations, developed the Uniform Drawing System (UDS) as part of the National CAD Standard. The UDS provides:
Standard sheet identification and discipline designations
A recommended order for drawing disciplines within a set of contract documents
Consistent organization to help all project participants find information efficiently
The UDS discipline order groups drawings by discipline in a typical sequence, for example:
General (G) – often includes Cover Sheet, Sheet Index, Life Safety
Civil (C)
Landscape (L)
Architectural (A)
Interiors (I)
Structural (S)
Mechanical (M)
Electrical (E)
Plumbing (P)
Fire Protection (FP)(and additional disciplines as needed)
The order given in the question:
Cover Sheet, Sheet Index, Life Safety, Demolition, Civil, Landscaping, Architectural, Interiors, Structural, Mechanical, Electrical, Plumbing, Fire Protection
matches the intent of the Uniform Drawing System discipline grouping and ordering:
The initial items (Cover Sheet, Sheet Index, Life Safety, Demolition) fit within the General / Architectural front sections.
Then the disciplines follow in a sequence consistent with UDS recommendations: Civil → Landscape → Architectural → Interiors → Structural → Mechanical → Electrical → Plumbing → Fire Protection.
Therefore, this is an example of UDS-based drawing set organization, which corresponds to Option B – Uniform Drawing System.
Why the other options are incorrect:
A. Traditional drawing set organization“Traditional” is vague and not a CSI-standardized system. The sequence in the question clearly follows a recognized CSI / NCS discipline order, not just an informal tradition.
C. AIA CAD Layer GuidelinesThe AIA CAD Layer Guidelines address layer naming conventions in CAD files, not the order of sheets in a printed / published drawing set.
D. BIM ImplementationBIM is about digital building information models and processes. It does not by itself define a sheet order; the sheet organization is still typically based on CSI / UDS discipline sequence, even on BIM projects.
