Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are
subject to periodic review and are kept up to date by the issue of amendments or new editions as
necessary. It is important therefore that Standards users ensure that they are in possession of the latest
edition, and any amendments thereto.
Full details of all Australian Standards and related publications will be found in the Standards Australia
Catalogue of Publications; this information is supplemented each month by the magazine ‘The Australian
Standard’, which subscribing members receive, and which gives details of new publications, new editions
and amendments, and of withdrawn Standards.
Suggestions for improvements to Australian Standards, addressed to the head office of Standards
Australia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian Standard
should be made without delay in order that the matter may be investigated and appropriate action taken.
This standard was issued in draft form for comment as DR 84099.

PREFACE
This standard was prepared by the Association’s Committee on Technical Drawing. It
constitutes Part 301 of a new multi–part standard designated AS 1100, Technical Drawing,
which supersedes the 13–part standard AS 1100, Drawing Practice.
The following Parts have been published:
Part 101—General Principles
Part 201—Mechanical Drawing
Part 401—Engineering Survey and Engineering Survey Design Drawing.
Concurrent with this Part 301 is published Part 501, Structural Engineering
Drawing.
This Part 301, Architectural Drawing, supersedes AS 1100, Part 13–1978.
It was in 1976 that the above committee decided that rather than have a standard
of many parts it would be better if all aspects of technical drawing were
consolidated into fewer parts that would embrace the entire discipline.
The designation AS 1100 has been retained for this new multi–part standard since
it is already well established throughout industry and teaching institutions as the
Australian standard number for technical drawing. However, to identify these new
editions from the previous ones, the designation of 3–digit Part numbers has been
employed.
This Part 301 deals with architectural drawing and changes from the previous
edition, AS 1100, Part 13–1978, are relatively minor. There has been some
redrafting and rearrangement in order to align with Part 101. Colour–coding
provisions from the former AS CA25–1955 have been restored. Some additional
symbols are given. Dimensional coordination, which has not become as common
as previously expected, has not been included in this edition.
It must be remembered that an architectural drawing is essentially a means of
communication between all parties involved in the planning, design and
construction of the building represented. The aims in its preparation should include
clarity, consistency, ease of comprehension, freedom from ambiguity, and
completeness of information without superfluity.
Care should be taken not to confuse the symbols given in this standard with the
scaled plotting of features which should be the adopted practice where practicable.
Consideration must be given to line thickness, symbol height and lettering to
ensure that they are suitable for the drawing scale, sheet size and possible filing
method, e.g. microfilm.
This standard is intended to be suitable for both manual and computer–aided
drafting.
Supplement No 1 to this standard gives drawings illustrating the use of
conventions specified in the standard.

TECHNICAL DRAWING
PART 301 — ARCHITECTURAL DRAWING
SECTION 1. SCOPE AND GENERAL
1.1 SCO PE. This standard sets out recommendations
for architectural drawing practice. It is complementary
to AS 1100, Part 101.
This standard indicates methods of presenting drawings
of architectural work, before, during and after the
construction period.
The standard includes information on abbreviations
(additional to those in AS 1100, Part 101), the layout of
drawing sheets, line conventions, and conventions for
the cross-referencing of drawings, coordinates and
grids. Sample drawings are given in Supplement No. 1,
published separately.
1.2 APP LICATION . The principles given in this
standard are intended for adoption by architects,
engineers, drafters and builders in both Government
authorities and private enterprise throughout Australia.
The standard is intended as a basis for common
practice, upon which technical organizations can base
their own detailed rules or manuals for the preparation
and presentation of drafting work.
The application of this standard may require reference
to AS 1100, Part 201, Part 401 and Part 501, AS 1101,
Part 5 and AS 1102, Part 8.
1.3 REFERE NC ED DOCU MEN TS. The following
standards are referred to in this standard:

AS 1155 Metric Units for Use in the Construction
Industry
AS 2700S Colour Standards for General Purposes
SA A MH2 Metric Data for Building Designers
1.4 DEFINITIONS . For the purpose of this standard,
the definitions given in AS 1100, Part 101, and the
following apply:
1.4.1 Job datum — a clearly defined and accessible
marker which will be visible and unlikely to be disturbed
during the course of a job, from which the required
reduced levels of the parts of a building or its site can
be readily measured during construction.
1.4.2 Level — the height or depth of an object or point
related to a specified datum. Where possible, this
datum should be the Australian Height Datum.
NOTE: In engineeri ng survey drawing, the term ‘height’
instead of ‘level’ is used to defi ne verti cal positi on (see AS
1100, Part 401). However, in archit ectural practice, the term
‘height’ is used for a vert ical distance or interval, e.g.
fl oor- to-f loor height.
1.4.3 Reduced level (RL) — a level related to a
nominated datum.
1.4.4 Reflected plan — the plan of a ceiling or the like,
viewed from above as if reflected by the upper surface
of a horizontal plane of section below the ceiling.
1.4.5 Section — the projection of the cut in an object
made by a cutting plane on a plane parallel thereto.
1.5 CLASSIFICATION OF DO CUMENTS.
1.5.1 General. For clarity in communication and to
enable information to be found quickly, documents shall
be classified according to the type of information to be
presented.
Each should contain only information which is
appropriate to its category. Drawings should not contain
information which can be better conveyed by schedules
or specifications, and vice versa.
1.5.2 Document classification.
1.5.2.1 Types. For the purpose of classification,
documents may be identified as ‘drawings’ or ‘other
documents’, as outlined in Clauses 1.5.2.2 and 1.5.2.3.
1.5.2.2 Drawings.
(a) Drawings at design stage.
(i)
Schematic drawing — a preliminary design
drawing, sketch or diagram showing in
outline form the designer’s general intention.
(ii) Development drawing — a design drawing
developed to show the building and site as
envisaged by the designer and from which
production drawings can be produced.
(b) Drawings at production stage.
(i)
Location drawing — a drawing produced in
order that drawing users mayA.
gain an overall picture of the layout and
shape of the building;
B.
determine setting-out dimensions for
the building as a whole;
C.
locate and identify the spaces and parts
of the building, e.g. rooms, doors,
cladding panels, drainage; and
D.
pick up references which lead to more
specific information, particularly about
junctions between the parts of the
building.
COPYRIGHT
5
Each group of location drawings will almost
always include site plans, floor plans,
elevations, sections and, very often, drainage
plans, but there will be occasions when
further categories, such as joist layouts,
reflected ceiling plans or the enlargement of
complex areas may be necessary.
(ii) Component drawing — a drawing to show the
information necessary for the manufacture
and application of components. Information
on basic sizes, and system or performance
data are often also shown.
(iii) Assembly drawing — a drawing to show in
detail the construction of buildings and
junctions in and between elements and/or
components.
1.5.2.3 Other documents. Other documents identified
at production stage are-
AS 1100.301—1985
specification — a precise description of materials
and workmanship of a project or parts thereof
which are not shown on drawings or in schedules;
(b) schedule — tabulated information on a range of
similar items differing in detail, such as doors,
windows, etc; and
(c) bill of quantities — a complete measure of the
quantities of material, labour and any other items
required to carry out a project based on the
specification, drawings and schedules.
1.6 LEG END S. Where appropriate, legends shall be
provided in respect of items not represented by
standard symbols, such as the following:
(a) Existing work.
(b) Set-out lines.

SECTION 2. GENERAL APPLICATIONS
2.1 DIMENS IONING. Units and methods used in
dimensioning of drawings shall be in accordance with
AS 1100, Parts 101 and 201, and AS 1155. Dimensions
may be indicated in accordance with the following
conventions:
NOTE: The use of tolerances as in dimensional coordinati on has not been generally adopted
and therefore is not included in this editi on of the standard. Drawing off ices can still use this
method if desired. Examples of drawings are given in SAA MH2.
2.2 LINES.
2.2.1 Type of line. A type of line appropriate for each
application should be selected from Clause 3.1 of
AS 1100, Part 101, and used in accordance with
Table 2.1(B) herein.
2.2.2 Line thickness. Line thicknesses shall be
selected in accordance with Clause 3.2.1 of AS 1100,
Part 101, except that a continuous medium line may
also be used (designated M in Table 2.1(A) herein).
The examples shown in Table 2.1.(A) are taken from
line group 0.7 mm which is generally favoured. A line of
thickness 0.25 mm or less may be difficult to reproduce
in reductions, and is not recommended.

2.3 SYM BOLS. The symbols given in Table 2.2 should
be used to indicate relevant features on drawings
prepared for general or communication purposes, but
only where drawing to scale is impracticable.
NOTE: Symbol size and line thickness will depend on
drawing size and scale. Symbols given have therefore not
been dimensioned.

TABLE 2.2 (continued)
GE NER AL SYMBOLS
NOTE: It is recognized that numerous tr acing templates wit h dif feri ng symbols are available,
and that the increasing applicati on of computer-aided drafti ng packages will generate an ever
wider variation of symbols. The symbols given are examples of standard symbols that can be
drawn manually.
Where possible, the symbols should be drawn wit hout their associated abbreviati ons, to
minimize clutt er and improve clarit y. Abbreviations should not be required, for example, where
a larger scale drawing is cross-r eferenced, but may be required if there is a need for other
symbols of similar appearance.
Examples of other items not included are:
Refr igerator, dishwasher, clothes washer, clothes dryer, cooker, wall oven, cleaner’ s sink.
Most of these would be squares or rectangles (possibly wit h a diagonal through them) and the
associated abbreviation.
Cleaner’ s sink would look very similar to tub-single, therefore identi fi cati on lett ers would need
to be added to the symbol.
Some symbols shown in AS 1100, Part 401, are applicable to block and site plans.

2.5 DE SIGNATION AN D CODING OF SP ACE S AND
COMPO NEN TS.
2.5.1 G eneral. Rooms or enclosed spaces,
components, units of equipment and other items may
be numbered to facilitate identification, both on
drawings and on schedules.
2.5.2 Sequence of numbering. The numbering or
referencing should follow a logical sequence, the
method adopted being dependent on the nature of the
job. Generally, numbering should proceed clockwise.
2.5.3 Designation of levels. Where the use of
conventional terminology, e.g. basement, ground floor,
first floor, etc., could be confusing, building levels
should be numbered from the lowest level (Level 1)
upwards.
2.5.4 Designation of rooms and spaces. A
numerical sequence starting with 1 should be used to
designate rooms and other important spaces on each
level. Sm all cupboards should not be given a separate
number but be allocated the number of the room in
which they are situated followed by an appropriate
suffix.
Stairs, ducts, shafts, etc which are continuous through
two or more levels should be given the same number
on each level with an appropriate distinguishing name
or letter prefix, e.g. Stair 3 or Stair S3.
In written documents the room or space reference can
be identified by prefixing it with the level number on
which it occurs, allowing sufficient digits for
identification of all rooms and spaces. Thus, where
there are between 10 and 99 rooms —
AS 1100.301—1985
2.08 means level 2, room 8, (not level 20, room 8)
2.12 means level 2, room 12
10.01 means level 10, room 1.
2.5.5 Identification
of com ponents. Where
appropriate, suitable identification may be allocated to
each class of component or item of equipment. The
nomenclature adopted shall be clearly stated both on
drawings and on schedules. Numbering within each
class should be consecutive, starting from 1.
Additionally, a type number or letter may be shown if
this is desired. Numbering may start from 1 on each
floor or may be consecutive for the whole building, as
convenient.
When reference is made to a component or item of
equipment other than on the plan on which it is shown,
the appropriate level number should precede the
reference, as for spaces (see Clause 2.5.4).
2.5.6 Identification
of windows and doors.
Windows and doors should be cross-referenced to
drawings or schedules as shown in Appendix A,
item(e).
2.6 DRA WING SCA LES . Drawings should have a
minimum scale for joint details of 1:20, to allow for
reduction of prints to half-size.
2.7 LAY OUT OF DR AWING SHE ETS. The layout of
drawing sheets should comply with the examples given
in AS 1100, Part 101, except that additional widths of
margins may be provided to allow for the binding or
edging of drawings or for rough handling on site.

SECTION 3. INDICATION OF LEVELS AND GRADIENTS
3.1 EXP RES SION OF LEVE LS
and consist of the symbol + placed at the exact
spot to which the level applies, followed by the
numerals for the proposed and/or existing level,
thus:
3.1.1 General. Levels should be expressed to the
nearest multiple of 5 mm or 0.005 mm and the
numerals for the required level should be enclosed in a
drawn rectangular box. Where the level of an existing
feature is to be varied, the existing level should be
placed directly above the box containing the required
level, thus:
(c)
Where there is a possibility that levels might be
confused with other numerals on a drawing, e.g. room
numbers, linear dimensions or grid references the use
of the prefix RL (reduced level) or FFL (finished floor
level), as applicable, is recommended, thus:
Contour lines . Contour lines are used to indicate
the slope and shape of the ground surface. They
shall be drawn to pass through all points on the
site having the same RLs. The RL represented is
placed at the end of each line at the site boundary,
or in the case of large sites may be placed at
intermediate points in or on the line.
The type of line, in accordance with line
designating letters given in AS 1100, Part 101,
shall be as follows:
3.1.2
Levels on plan. There are three general
methods for the indication of levels on plan views, as
follows:
(a) Job datum level . The job datum level is indicated
by the symbol followed by the numerals for that
level, thus:
(i)
For existing surface, to remain unchanged
...continuous thin, type B or C.
(ii)
For existing surface, to be changed...dashed
thin, type E.
(iii)
For required finished surface....continuous
thin, type B or C.
NOTE: In engineering survey drawing, ‘height’ is
used instead of ‘level’ (See Clause 1.4.2.)
The position of the job datum should be clearly
marked on site plans together with a short
description and its assumed level which should be
such that all of the reduced levels specified for a
given job will be positive numbers.
3.1.3 Levels on section or elevation. Levels, existing
or proposed, should be projected clear of the detail by
means of an extension line and indicated as shown in
Fig. 3.1. A box is not required when a level is written
on such a line drawn in elevation.
(b) Spot levels . Spot levels are used to indicate the
required level for a specific point or limited area

3.2 EXP RES SION OF GRA DIENT.
For the
specification of vertical angles which are capable of
being established on-site by means of simple
measuring devices, the gradient (slope, pitch, fall or
incline) of surfaces, such as roofs, gutters, ramps, etc.
should be expressed in the form of a numerical ration
Y:X, where Y is the vertical dimension and X is the
horizontal dimension of a right-angled triangle the
hypotenuse of which is the slope (see Fig. 3.2).
For convention, the vertical dimension will always form
the first part of the ratio.
AS 1100.301—1985
Thus for gradients flatter than 1:1, the first number will
be unity e.g. 1:20, and for gradients steeper than 1:1,
the second number will be unity e.g. 5:1.
The use of angular measurement for slopes in degrees
or radians is still acceptable in certain cases where a
higher degree of accuracy is required.
3.3 ORIENTATION OF PLANS . A north point should
appear on every plan. Wherever practicable, all plans,
including the site plan, should be drawn with the same
orientation. The site location plan should be drawn with
the north at the top of the sheet irrespective of the
orientation of the other plans.

AP PE ND IX B
DIMENSIONING BY COORDINATES AND USE OF GRIDS
B1 DIME NSIONING BY COORDINATES. Dimensioning by coordinates can be used
where a building or structure is so set out that the faces or centrelines of its elements
coincide with, or can be related to, the intersection points and lines of a regularly spaced
three-dimensional grid. The elements can be located and dimensioned in relation to a
point of origin by a system of Cartesian coordinates. Care should be taken that the origin
is external to the space occupied by the site or structure and can be physically
established. Only points on the positive sides of the x, y and z axes should be used.
In this system, the coordinates of a point on plan view shall be indicated by the relevant
figures (in x, y sequence) enclosed in brackets and placed at the right hand side of the
point to which they refer. The height of a point on elevational views, i.e. on the z axis,
should be shown by means of a horizontal grid line, terminating with a circle and the grid
reference height above the point of origin prefixed by the letter ‘z’.
B2 USE OF GRIDS.
B2.1 General. A network of lines or planes may be used for reference on a drawing or
on a site. Its use may be for sheet reference only or for actual setting-out of the work on
the site.
Grids usually consist of straight lines at set distances apart. They can vary from linear to
three-dimensional reference.
B2.2 Types of grid.
B2.2.1 Types . The types of grid are as follows:
(a) Sheet reference grid.
(b) Planning grid.
(c) Structural grid.
(d) Reference grid.
(e) Modular grid.
B2.2.2 Sheet reference grid. See AS 1100, Part 101, Clause 2.4.4.
B2.2.3 Planning grid. The use of a grid for layout and planning is often an advantage,
especially where prefabricated sections form a repeated module. Such a grid is termed
a planning grid.
B2.2.4 Structural grid. A grid used for locating structures is termed a structural grid.
Planning and structural grids should be related to preferred dimensions where possible.
They need not necessarily be to the same module, or even be increments of each other
in a simple mathematical relationship.
The grid should be drawn on the most stable paper or plastics sheet available so that
when it is used as an underlay successive floor plans or levels can be accurately drawn.
Generally, grid lines pass through column centres both ways except where the column,
duct or lift shaft face is critical in which case the grid line may coincide with that face. The
grid plan is usually determined at the lowest level and any changes in column locations
at upper levels are shown on it. The grid plan dimensions become the basis for all other
work on the drawing.
The grid is repeated on all subsequent drawings (with any necessary adjustment of scale)
and forms the base to which all plan dimensions are related.
B2.2.5 Reference grid. A grid intended for reference only may be to any selected
dimension and the lines need not necessarily be equally spaced. They can be regular or
tartan pattern, to suit the function required.
B2.2.6 Modular grid . Where a method of building using a module is adopted, a
two-dimensional or three-dimensional grid based on the module may be used to combine
the functions of planning, structural and reference grids.
When the basic module of 100 mm is adopted, a grid showing each module is
recommended for assembly drawings and a grid showing multi-modules of 300 mm or
600 mm for general location drawings.
B2.3 Grid notation. Different methods of grid notation have existed in the past.
The method used should be consistent throughout a project. Either of the following
methods is recommended:
(a) When completely defining the location of points by their distance from the origin in
three dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . x, y, z coordinates.
(b) When using a two-dimensional structural grid (see AS 1100, Part 501) . . . . . . letters
for lines running down the sheet and numbers for lines running across the sheet.
