5.0 Drawing Development

5.1 general

  • Confirm with client on requirement of metric or imperial format, otherwise, concrete & steel buildings are metric, wood frame buildings are imperial
  • Titleblock sheet numbers to have two digits (A2-01, A3-01, etc)
  • Itemized door schedule completed in Excel, door/frame elevations completed in Autocad, and both inserted in the specification
 

5.2 Cover Sheet

  • project name, client
  • legal description and civic address
  • key plan if required
  • full project statistics
  • consultants’ list
  • drawing lists
  • project image
 

5.3 Site Plan

  • survey information and building grades to be converted for metric format (confirm)
  • start with survey plan, strip away non-applicable information or copy and paste required
  • information to new drawing, and flatten everything – never work over or snap onto survey drawing
  • review legal survey plan and draw lot lines from surveyor’s bearings and distances if necessary to ensure site closes
  • option 1 (office standard) – use world ucs from survey plan, and rotate floor plan to suit
  • option 2 (use only under special circumstances with P.L. approval) – rotate site plan to suit world ucs created in floor plan
  • place survey in CAD with bottom left hand corner property line at the 0,0,0 point.
 

5.4 Floor Plan (1:100)

only one plan per file

  • place bottom left hand corner of building, work point or grid intersection at 0,0,0 point (try to keepthe drawing on the positive side of the x and y axis)
  • include 1:100 (1/8”), 1:50 (1/4”) and reflected ceiling plan info, use separate tab layouts for each sheet
  • plans should be set with the north arrow (true north) oriented upwards between 0 and 180 degrees
  • option 1 (office standard) – set new world ucs using a location that will not change (corner ofproperty line, grid intersection), and set with main plan view orientation
  • option 2 (use only under special circumstances with P.M. approval) – ucs world to remain per survey plan, rotate plans to suit, create working ucs’s
  • set other ucs’s and views as required for working orientation
  • xrefs to include grids, building section markers, concrete columns, concrete core (excluding stairs/rails) and suites (excluding exterior walls)
  • lock the grid xref layer
  • small scale drawings (1:100) located before large scale drawings (1:50)
  • exterior dimensioning and interior centerline column dimensioning
  • common area door tags, including suite doors with an frr greater than 20 minutes
  • window tags
  • detail referencing
  • establish block/xref naming guidelines with team members at initial project meeting; naming should be simple and consistent throughout the project; xrefs should have prefix of ‘x-***’ and located in a separate folder; suggested name as follows:
  • grids: ‘x-grid’, ‘x-grid-100’ (representing 1:100 scale)
  • suites: ‘x-suite-A’, ‘x-up-01’ (up=unit plan)
  • columns/core: ‘x-cols-l1’, ‘x-core-l1 (l* referencing particular floor level or levels)
  • windows (not xref):
 

5.5 Floor Plans (1:50)

  • show detailed information for typical suites only, reference all others, including mirrored suites
  • interior suite and common area dimensions
  • suite door tags
  • suite and common area wall tags
  • no exterior wall tags, except for interior furring, all other assembly information shown on details
  • xref construction assemblies file (walls only); assemblies with graphics can be shown on separate sheet only under special circumstances with P.L. approval; roof and floor assembliesshould not be shown in the assemblies listing, rather show in sections and details
 

5.6 elevations and sections (1:100)

  • create separate ucs’s and views to wrap around floor plan (ie. use N for north and AA for section A-A)
  • each ucs to be defined off of datum, so building heights can be located accurately
  • typical elevation of a floor plate to be created as block
  • window to be created as block and xclipped around solid objects (guardrails, columns)
  • window tags to match those on floor plans
  • detail, wall section and section referencing
  • hidden portions of building should be elevated and shown as part of building section if applicable,if not shown in section, please elevate separately on elevation sheet
 

5.7 Reflected Ceiling Plans (1:100)

  • included in floor plan file, in a separate layout tab
  • all common area and typical suites
  • depending on amount of information shown, freeze plan information (doors, millwork, etc.) and add door headers
 

5.8 Vertical Circulation (1:50)

  • include elevator core
  • xref plans and building stair section into a separate file and offset from each other
  • dimensions, tags and text to be included in this drawing and not in base plan
  • include standard railing details
 

5.9 Window Schedule (1:50)

  • include in schedule file along with door schedule
  • use window blocks created for the elevations
 

5.10 Details

  • minimum scale is 1:5 (1 1/2”), with blow-up typical window/door head/jamb/sill at 1:2 ( 3”)
  • section details to be drawn in a separate file over top of the x-ref’d building section, miscellaneous details can be drawn off to the side
  • plan details to be drawn in a separate file over top of the x-ref’d floor plans
  • drawing sheet – number details from top to bottom, left to right (preferable but not mandatory)
  • detail book – xref the floor plans or building sections into separate files, screen the xref layers, and draw details over top
  • inclusion of smaller scale wall sections depending on complexity of project, and to be located before the details, at 1:20 scale
  • note exterior wall assembly only once, and reference location in all other details
  • terminology to explicitly follow the specification; review outline specification as early as possible
  • verify technical assemblies and products with P.L. as early as possible; note generic names, never product names
  • detail book numbering as follows:
  1. D100 - parkade and site details up to and including level 1, including podium
  2. D200 - plan details from level 2 and up
  3. D300 - section details from level 2 and up
  4. D400 - enlarged window/door details
  5. D500 - miscellaneous details
