BUILDING DRAWINGS CHECKLIST:ARCHITECTW DRAWINGS*byC.S.StrelkaPREFACEThis drawing checklist provides architects with a convenient toolfor the final review of drawings prepared under their supervision,Since this list is a general one, it cannot claim to cover all thespecial situations which can o.ccur in practice; nevertheless it shwldprove helpful as a basic guide. Users of this checklist are stronglyurged, before putting it to use, to consult the Canadian NationalStandard CAN 3-H 78.3-M77 Building Drawings (published by and availablefrom the Canadian Standards Association, 178 Rexdale Blvd., Rexdale,Ontario) or the Manual on Metric Building Practice (published by andavailable from the Division 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 to the person checking thedrawings. The matter of "crispness of drawing", for example, cannot beoveremphasized, particularly in plans drawn at 1:100 scale wherecomposite 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 checkingstage. Free space f s provided on most of the sheets for 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)sof mare.The architect must critically revfew his own work before releasingit to a contractor for execution. It is his professional responsibility,an obligation to his client and the key to a good business reputation.The author wishes to thank Dr. Alan 3. Wilson, of the LiverpoolFolytechnfc, England, for his many useful suggestions on the preparationof this paper.*The original title "BUILDINGS DRAWINGS CHECKLIST" has been changed todistinguish this article from future ones in the same series.

CBECWNG DIMENSIONSThe dimensioning method should be consistent, meticulous and inaccordance with the I-Jatforial Standards of Canada CAN 3-B 78.3-M77Building Drawings.1.1 Linear dimensions should be expressed in millimetrres (mm) onbuilding drawings, and in metres (m) on site plans. According tothe standard convention 5n drafting, the unit symbol can be omittedif the follming requirements are met:a) a note indicating the unit used is displayed in a conspicuousplace on the drawing sheet;bl all linear dimensions including those for spot levels and landelevation contours are given in one dimensioning unit only.For easier readlng, group the digits in triads on both sides of thedecimal marker (e.g., 123 456 789). All dimensions shown in metres mustbe taken to three decimal places, even when all 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 lot plans to three decimals (e,g, , 1.234 ha).b) square metres (m2) for floor 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 dimnsions should be expressed in:a) cubic metres (m3) for volumes of earthwork, excavations,concrete, fluids in 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.

Operation InstructionsInstalling Mixer Bowls - All Models1. Place the bowl on the two arms to keep it in place. Insert the bowl pin into pin support located on frame.Carefully align holes on the bowl with the studs on the bowl arms. (Fig.1)2. Once the bowl is seated properly, swing the locking levers into position. (Fig.2)3. To remove the bowl, follow the instructions above in reverse order.Fig.1VFM10 / SP200SP300Fig.27
