Working Drawings Handbook
of small details on any project which it would be
pointless to draw in one corner of an A1 sheet and
which it would be confusing to attempt to collect
together on a single sheet (the ‘miscellaneous details’
approach which has been condemned earlier).
Where the format for the other drawings is A2 it is
probably worth wasting a little paper for the sake of
obtaining a manageable set of consistent size. Where
the general size is A1 however, a smaller sheet
becomes necessary and whether this should be A4 or
A3 is a matter for some debate.
A4 or A3? It may be helpful to set out the pros and
cons. The advantages of the A4 format are: A substantial amount of the project information
is already in A4 format—specification, bills
of quantities, architect’s instructions,
correspondence, etc.
Trade literature is normally A4 and if you wish to
include manufacturers’ catalogues as part of your set
(and why not?) then they are more readily absorbed
into the structure of the set if you already have an A4
