lines) on the 12-inch-wide units indicate that the
thickness of the wall beyond the pilaster is 8 inches.
Note how the extra 4-inch thickness of the pilaster
provides a center support for the girder, which, in
turn, will support the floor joists.
Details are large-scale drawings that show the
builders of a structure how its various parts are to be
connected and placed. Although details do not use the
cutting plane indication, they are closely related to
sections. The construction of doors, windows, and
eaves is customarily shown in detail drawings of
buildings. Tyical door and window details are shown in
figure 2-18. Detail drawings are used whenever the
information provided in elevations, plans, and sections
is not clear enough for the constructors on the job.
These drawings are usually grouped so that references
may be made easily from the general drawing.

A schedule is a group of general notes, usually
grouped in a tabular form according to materials of
construction. General notes refer to all notes on the
drawing not accompanied by a leader and an
Item schedules for doors, rooms,
footings, and so on, are more detailed. Typical door
and window finish schedule formats are presented in
the next section.
Doors may be identified as to size, type, and style
with code numbers placed next to each symbol in a
plan view. This code number, or mark, is then entered
on a line in a door schedule, and the principal
characteristics of the door are entered in successive
columns along the line. The Amount Required
column allows a quantity check on doors of the same
design as well as the total number of doors required.
By using a number with a letter, you will find that the
mark serves a double purpose: the number identifies
the floor on which the door is located, and the letter
identifies the door design. The Remarks column
allows identification by type (panel or flush), style,
and material. The schedule is a convenient way of
presenting pertinent data without making the Builder
refer to the specification. A typical door schedule is
shown in table 2-1.
A window schedule is similar to a door schedule
in that it provides an organized presentation of the
significant window characteristics. The mark used in
the schedule is placed next to the window symbol that
applies on the plan view of the elevation view
(figure 2-13). A similar window schedule is shown in
A finish schedule specifies the interior finish
material for each room and floor in the building. The
finish schedule provides information for the walls,
floors, ceilings, baseboards, doors, and window trim.
An example of a finish schedule is shown in table 2-3.
