The number of drawings required is likely to be influenced by the size of the
project, the procurement method to be adopted (i.e. who actually produces
the drawings) and the relative significance of drawn information in relation to
other contract documents.
Whatever drawings are produced it is important to be clear about their intended
purpose and the needs of the user of the drawing. Any drawing should provide
such information as shape or profile, dimensions (notional or finished), position,
composition and relation to other parts, including tolerances, fixing methods,
etc. On a simple project, where only a small number of drawings is necessary,
these might embrace the needs of all trades and suppliers and be annotated to
the extent that no other supporting document is required.
Conversely, more complex projects will require a considerable number of
drawings and schedules, each devised with a particular trade or element in mind.
Cross-referencing to other drawings will be required, which must be carried out
with great care.

Design drawing and schedule programme is given in Figure 4/1.
Schedules
Some information is more clearly and conveniently conveyed in schedule form.
Schedules commonly include:
• ironmongery (with location and fixings)
• doors
• windows (to include glazing)
• finishes (floor, walls, ceilings)
• precast lintels and sills
• inspection chambers and manhole covers
• colours.
Any elements or components which are repetitive or can be grouped may be
suitable for scheduling. The exercise is a good coverage check for compilers,
but information should not be repeated on the drawings as this might lead to
confusion and inconsistencies.
It is quite common for suppliers to provide schedules on the architect’s behalf,
but these should be thoroughly checked.
