The general arrangement drawing
Such references are useful in relating a point on the
elevation with its corresponding position on the plan,
but the elevation should never be regarded as the
primary source of reference for these components.
Regardless of whether or not they appear on the
elevations, it is essential that the references appear
on the appropriate general arrangement plans. The
references in 2.16are to the external openings
schedule.
2 They may be used to identify the type and extent of
external finishes; this is a useful device, for it is not
easy by any other means to indicate such things as
patterned brickwork, the change from one type
of bond or pointing to another, or soldier courses
(see preceding 2.14).
3 They may be used as both location drawings
and schedule for cladding panels or ashlar
facings (2.17).
4 They may be used to convey information about
external plumbing and drainage services above
ground level (2.18).General arrangement sections
General arrangement plans in effect constitute a
series of horizontal cross-sections through the
building, spaced out so that one is taken at every floor
level. This spacing is reasonable, since in practice the
appearance of the horizontal section is most likely to
differ from floor to floor and unlikely to differ between
floor and ceiling.2.16 Elevation as a secondary reference to window components. The reference S/31 leads back to the
external seconday elements schedule, where the components are listed and classified
