working drawings is

• Working drawings are usually
drawn in ink.
• Modern drawings are now
drawn by means of a
computer which produces
very accurate drawing much
quicker than before.

1
Block Plans
These are used to identify the site in relation to the
surrounding area
2
Block Plans
• The scale is usually 1:2500, 1:250 and is too
small to allow much more than an outline of the
site and boundaries, road layouts and the other
buildings in the near vicinity.
• The orientation of the site is always shown with
a suitable logo depicting north.
• The actual site should be outlined in red.
• It is not likely that dimensions would be added to
these drawings.
• Plans of this sort are usually based on the
Ordnance Survey sheet for the area however, if
such a source is used, permission should be
obtained for its reproduction.
3
Site Plans
These are used to show the position of the proposed
building on the site, together with information on
proposed road, drainage, and service layouts, and other
site information such as levels.
4
Site Plans
• The orientation of the site should be shown.
• Scales of 1:500, 1:200 are often used.
• The information on this drawing is used by both the
design team and the contractors.
• The drainage layout should be used in conjunction
with the drainage schedule, which will give details of
manhole construction, cover and invert levels, and
other relevant information.
5
Location Plans
These are used to show the size and position of the
various rooms within the buildings and to position the
principle elements and components.
6
Elevations
• Elevations consist of a
series of views of a building
or object.
• The views are front
elevation, side elevation
and rear elevation.
• They are drawn to a scale
of 1:200, 1:100, 1: 50
depending upon the detail
required.
• Elevations to scale of 1:200
will not show as much detail
as elevations to a scale of
1:50.
• Elevations show the
building as a finished
building from all directions.
• These drawings have a
limited amount of
information and dimensions
on them, this must be
obtained from other
drawings.
7
Plans
• These are cross
sectional views of a
building sowing the
position and size of all
rooms, toilets,
bathrooms, entrances,
the position of
windows etc.
• It also shows the
circulation routes and
overall character of
the building.
• These drawings are
drawn to a scale of
1:200, 1:100 and 1:50
and usually match the
elevations in size.
• Because of this they
are still too small to
show much
information or
dimensions.
8
Sections
• The sectional view of a building will show details which
otherwise would not be seen on the plans and elevations.
• These drawings can show a cross sectional view or a
longitudinal view of the building and can display either a full
cross section or a part cross section.
• A full cross section will show the full height of the building
and its respective floor and ceiling levels.
• Depending on the scale chosen, information will be
restricted to that which could not be found in other drawings.
9
Component drawings
• These are some times called range drawings. These show
the basic sizes of standard components such as doors,
windows and kitchen fitments.
• The scales most commonly used are 1:100, 1: 50, 1: 20.
• The drawing below shows a range of windows. These can be
obtained from any manufactures catalogue or from the
working drawings.
• All windows are referenced i.e. W1, W2, W3 etc
• These refer to the working drawings and the window
schedule.
10
Detail drawings
• These show all the relevant information that is required to
manufacture various components such as doors and
windows etc
• These drawings will include every detail required to make the
product.
• The information from these details is used to manufacture
various components.
• These drawings are usually produced by the architect and
are produced in scales ranging from 1:1, 1: 5, or 1:10.

Assembly drawings
•
•
•
These drawings show in detail the junction between the
various elements and components of a building
These drawings are very important to the builder. They
show in detail how the architect requires the construction to
be constructed and what materials should be used.
The scales usually used for these drawings are 1:20, 1:10,
and 1:5 and should be fully dimensioned and annotated.
