Show building section graphics
- All building conditions and components at section line are shown: footings, foundations, walls, floors, ceilings, roofs, openings, decks, parapets, appendages, gutters
- Type, location and thickness of thermal insulation envelope is shown: ground floors, walls, roofs, exterior soffits
- Space is provided for thermal insulation at roof for ventilation
- Type, location and thickness of acoustical insulation is shown: walls, ceilings, floors
- Location of new and existing grades at section line are shown
- New grade slopes to drain or away from building
- Drainage components at section line are shown: drain lines, drainage fill, trenches
- Types and location of all firestopping are shown
Show building section dimensions
- Heights for all stories are dimensioned: floor-to-floor, floor-to-roof, floor-to-ceiling
- Sill and head heights of openings not shown elsewhere are dimensioned: doors, windows, louvers
Show code-required control lines
- All code-required control lines are shown: building height limitations, property lines, setback lines
- Control lines shown are sufficient to demonstrate that building conforms to code requirements
Show detail cross references
- Every unique wall and component detail not keyed in elsewhere is keyed in
Show other cross reference symbols
- All building section cut lines are keyed in
Show material identifications
- Every building material or component at section line is identified by abbreviation, keynote, or symbol: foundations, walls, floors, roofing, openings, appendages, insulation types
- Each material symbol identifies only one type of material
Show building section notations
- Every room name of room at section line is shown
Show sheet notes
- Sheet title is shown
- Building section titles and scales are shown
Do interference check
- Adequate vertical clearance provided for concealed building components: ducts, sloping sewer lines, light fixtures, structural members
Coordinate with office standards
- Format for notations conform to office standard: sheet notes, elevation names
- Every item is drawn on appropriate CAD layer, conforming to office standard
- Every keynote conforms to office standards
Coordinate with legend
- Every cross reference symbol is listed and described in legend
- Every material symbol is listed and shown in legend
- Every abbreviation matches definition in legend
- Only abbreviations defined in legend are used
Coordinate with other drawings
- Building section agrees with floor plans, elevations, structural drawings
- Existing grade conditions agree with survey
- New grade conditions agree with site plan, landscape, civil drawings
- Drainage components agree with mechanical, landscape, civil drawings
- Sheet title agrees with table of contents
- Every detail and other cross reference symbol refers to correct reference and sheet
- This is an incremental task. It's usually started in DD phase and completed in CD phase.
- Work prior to completing building sections, like laying out the sheet and adding title blocks are not included here. They will be covered under other tasks.
- Legend refers to list of symbols and abbreviations, usually on cover sheet.
