Generate a complete drawing sheet index per AIA/CSI conventions. Enable disciplines, set sheet counts, and get a full sheet list with standard numbering — ready to import into Revit or export as CSV.
This tool generates drawing sheet indexes following AIA (American Institute of Architects) and CSI (Construction Specifications Institute) numbering conventions. Select your project disciplines, configure sheet counts, and get a complete numbered sheet list — ready to import into Revit's Sheet Index schedule or export to CSV for BIM 360 transmittal logs.
The AIA CAD Layer Guidelines and BIM Protocol documents establish a standard discipline-prefix system for construction drawing sheets. Each sheet number begins with a single (or double) letter code for the discipline: G (General), C (Civil/Site), A (Architectural), S (Structural), M (Mechanical/HVAC), P (Plumbing), E (Electrical), FP (Fire Protection), T (Technology/Low Voltage), I (Interiors), L (Landscape). The prefix is followed by a three-digit number where the first digit typically indicates the drawing type: 0xx = General/Notes, 1xx = Plans, 2xx = Elevations or Demolition, 3xx = Sections or Enlarged Plans, 4xx = Details or RCPs, 5xx = Schedules or Equipment Plans, 6xx = Diagrams, 7xx = Details, 8xx = Specifications or Special Plans, 9xx = Reports or Calculations.
In Revit, the Sheet Index is a standard View Schedule. Go to View → Schedules → Sheet List. The default fields include Sheet Number, Sheet Name, Drawn By, Checked By, and Issue Date. The Sheet Number field in Revit stores the full sheet number (e.g., "A-200") — the prefix and number are stored together, not separately. When setting up a new Revit project per the AIA numbering system, use this generator's output as your baseline: create all sheets in Revit with the generated numbers and titles before beginning modeling. This ensures the sheet index is organized from day one and won't require renumbering mid-project when coordination sets are issued.
For multi-user projects with Revit worksharing, sheet creation should be restricted to the BIM Manager's account by setting the Sheets workset to not be editable by default, preventing duplicate sheet numbers from being created simultaneously.
In BIM 360 (now Autodesk Construction Cloud / ACC), the Sheet index integrates directly with Revit sheet publishing. When you publish sheets from Revit via the BIM 360 Revit plugin or Design Collaboration, the sheet number and title become the document identifiers in ACC. A well-structured sheet index at project start means all published sheets are correctly identified without manual renaming in ACC. Use the CSV export from this tool to pre-populate an ACC transmittal log or document register. The CSV format (Sheet Number, Sheet Title, Discipline) can be directly imported into ACC's Document Management module or used as a basis for a Procore drawing log.
Healthcare and data center projects often have more complex sheet numbering due to the volume of drawings and multiple design phases. Common approaches: (1) Phase prefix — add a letter prefix for project phase: SD (Schematic Design), DD (Design Development), CD (Construction Documents). Some firms use: SD-A-200, DD-A-200, CD-A-200. (2) Area/zone prefix — for large campus projects, prefix with the building or zone: A1-A-200 (Building A1, Architectural, Sheet 200). (3) Package-based numbering — issue packages get a prefix: BP01-A-200 (Bid Package 1). The generator produces base AIA numbers — add your firm's prefix convention as a prefix to the generated numbers. ASHRAE 90.1 energy compliance documentation and NFPA 101 life safety drawing sets for healthcare typically require dedicated T-series and FP-series sheets to document compliance calculations separately from design drawings.
The AIA (American Institute of Architects) drawing numbering standard uses a discipline-prefix system where each sheet number begins with a letter code identifying the design discipline (A for Architecture, S for Structural, M for Mechanical, etc.) followed by a three-digit number. The first digit of the number typically indicates the drawing type (1xx = floor plans, 2xx = elevations, 3xx = sections, etc.). This standard is referenced in the AIA CAD Layer Guidelines (AIA CAD Layer Guidelines, 2nd edition) and the AIA BIM Protocol Exhibit.
Yes. The generated sheet numbers follow AIA conventions and can be entered directly in Revit's Sheet Number and Sheet Name fields. Use the Copy to Clipboard button to copy the full list, then paste into a spreadsheet and use it as a reference while creating sheets in Revit. The CSV export format can also be used with Dynamo scripts that batch-create sheets from a data source — search for "Revit create sheets from Excel Dynamo" for scripts that automate this workflow.
G-series sheets are discipline-independent general project documents: G-001 (Cover Sheet — project name, address, design team contacts, project description), G-002 (Sheet Index — this generator's output, updated with actual sheet titles), G-003 (General Notes and Abbreviations — standard construction notes, material abbreviations), G-004 (Life Safety and Code Analysis — occupancy classification, construction type, fire protection notes), G-005 (Phasing Plan — if applicable). Some firms combine G-001 and G-002 on a single cover sheet. The G-series sheets are typically issued first in any partial permit or design development submission.
FP (Fire Protection) sheets cover both fire suppression (sprinklers — NFPA 13) and fire alarm systems (NFPA 72). Some firms split these into separate series: FP for sprinkler/suppression drawings and FA for fire alarm drawings. Electrical engineers may include fire alarm on E-series sheets (particularly the fire alarm riser diagram and panel schedule), while the floor plans are on FP or FA sheets. The convention varies by firm. This generator uses FP as a combined fire protection prefix — adjust your firm's prefix as needed.
A typical mid-size commercial office building (50,000–150,000 SF, 3–6 stories) might have: G (4–6 sheets), A (18–35 sheets), S (8–15 sheets), M (6–12 sheets), P (4–8 sheets), E (8–16 sheets), FP (4–8 sheets), C (4–8 sheets for site work). Total ranges from 60–120 sheets for construction documents. Schematic Design submissions are typically 20–35% of the final CD set. Design Development is 50–70%. Use this generator with conservative counts for SD/DD submissions and increase counts for the full CD set.
