G(7–)001 1:100 Plan at level 1—Fixtures Self-explanatory, although it might be questioned what

G(8–)001 1:100 Plan at level 1—Loose equipment This coding seems to cover a multitude of omissions
002 2 — ,, in practice. Mirrors, notice boards, fire exit signs, fire
003 3 — ,, extinguishers—all tend to get added late in the life of

preferable to reserve an (8–) set of copy negatives
for eventual use.

Drawing number Scale Title Comments
provide will consist of, at the minimum:
1 Drawing category: i.e. general arrangement,
assembly, component or schedule.
2 Drawing element: its CI/SfB number, or other coded
reference.
3 Drawing number: its unique identification within the
category and element.
4 Revision suffix.
5 Scale: not essential to the record but can be helpful.
6 Size of sheet: because A4 and A1 drawings are
unlikely to be stored in the same container, and the
searcher must be told where to look. One test of the
effectiveness of a drawing retrieval system is that it
should always be quicker to locate the given drawing
in the register and then go to it straight away than to
leaf hopefully through the vertifile.
The date of completion and the dates of any revisions
are not included, for they will be recorded on the
drawings themselves. Neither is it desirable to use the
drawing register as a record of drawing issues. In the
first place this practice imposes an administrative strain
upon the drawing office, which is likely to act
unfavourably to seemingly bureaucratic procedures. In
the second place, there is really very little to be gained
from such a record. A check on drawing issues should
be possible from other in-built procedures, such as
standard drawing circulation lists or drawing issue sheets.
A CAD user would almost certainly maintain the drawing
register in electronic format as a computer file.
Status coding
As has been noted earlier, many drawings perform
different functions at different stages in their life, and
some system of identifying their function at a given
moment is a useful adjunct to a coding system.
One such method is to use the letter reference of the
appropriate RIBA stage of work in conjunction with the
drawing number, as follows:
E:Detail design drawing. Any working drawing up to the
time it is frozen for issue to the quantity surveyor, when
it becomes:
G:Drawing reconciled with bills of quantities. That is the
stage at which the drawings form part of a tender set.
