BUILDING DRAWINGS CHECKLIST: ARCH ITECTW DRAWINGS*by

C.S. Strelka

PREFACEThis drawing checklist provides architects with a convenient t oo lfo r the f i n a l review of drawings prepared under t h e i r supervis ion,Since this l i s t is a general one, it cannot c l a i m to cover all thespecial situations which can o.ccur in practice; nevertheless it s h w l dprove helpful as a basic guide. Users o f this checklist are stronglyurged, before p u t t i n g it to use, to consult the Canadian NationalStandard CAN 3-H 78.3-M77 Building Drawings (published by and available

from the Canadian Standards Association, 178 Rexdale Blvd., Rexdale,Ontario) or the Manual on Metric Build ing Practice (published by andavai lable from the Divis ion of Building Research, National ResearchCouncil of Canada).Part I of this checklist, which i& presented in narrative form,serves as a remtnder of various items t o the person checking thedrawings. The matter of "crispness of drawing", for example, cannot beoveremphasized, particularly in plans drawn at 1:100 scale where

composite wall canstructf,on is envisaged.Part I1 presents, in tabulated form, a checklist sheet far everysheet in a traditional set of working drawings. These tables can bephotocopied and attached to the appropriate drawfngs during the checking

stage. Free space f s provided on most of the sheets fo r additionalitems. Using the tables will thus simplify the process of reprintingcheck sets and/or establishing permanent records of all verifications andapprovals. They can also supplement computer-aided design (CAD)sofmare.

The architect must critically revfew h i s own work before releasingit to a contractor f o r execution. It is his professional responsibility,an obligation t o his c l i e n t and the key to a good business reputation.

The author wishes to thank Dr. Alan 3. Wilson, of the LiverpoolFolytechnfc, England, for h i s many u s e fu l suggestions on the preparationof t h i s paper.

*The original title "BUILDINGS DRAWINGS CHECKLIST" has been changed todistinguish t h i s article from future ones i n the same series.

C B E CWNG DIMENSIONSThe dimensioning method should be consistent, meticulous and i naccordance w i t h the I-Jatforial Standards of Canada CAN 3-B 78.3-M77

Building Drawings.1.1 Linear dimensions should be expressed in millimetrres (mm) onbuilding drawings, and in metres (m) on site plans. According to

the standard convention 5n drafting, the unit symbol can be omittedif the f o l l m i n g requirements are m e t :a) a note indicating the u n i t used is displayed in a conspicuousplace on the drawing sheet;bl a l l l inear dimensions including those for spot levels and landelevation contours are given in one dimensioning u n i t only.

For easier readlng, group the d i g i t s in tr iads on both s i d e s of thedecimal marker (e.g., 123 456 789) . A l l dimensions shown in metres m u s tbe taken t o three d e c im a l places, even when a l l deciraals are zeros(e'g., 1.235, 1.000).1.2 Area dimensions should be expressed fa:

a) hectares (ha) for areas on survey plans, plans of subdfvLsfonsand l o t plans to three decimals (e,g, , 1 .234 ha).b) square metres (m2) for f loor areas of rooms, cross-sectton areasof earthworks, large glass panes, etc. , to two decimals ( e .g . ,

1.23 m2).c ) square rnillimetres (min2) for structural areas and othersections, bars, etc . , using no decimals.

Symbola of these units MUST ALWAYS 33 SHOWN on drawings whereappropriate.1.3 Volume dimn sions should be expressed in:

a) cubic metres (m3) for volumes of earthwork, excavations,concrete, f l u i d s i n large quantities, etc.b) litres (L) for volumes pertaining to containers of fluids orgases only.

Symbols of these units MUST ALWAYS BE SHOWN on the drawings.
