Understanding Schedules 233
9.5 GRILLE/DIFFUSER SCHEDULES.
Grille and diffuser schedules generally show the manufacturer and catalog/model number of each grille
and diffuser. They also show the dimensions of each as well as the volume of air in cubic feet per minute
(CFM) that each will handle, the quantity required, and the location for installation. A column for notes/re-
marks is typically included to facilitate the installation of the item.
9.6 LIGHTING-FIXTURE AND ELECTRICAL SCHEDULES
Lighting-fixture schedules are generally used to list the fixture types and identify each fixture type on the
drawing of a given project by number. The manufacturer and identification number of each type are given
along with the number, size, and type of the lamps for each. One can include a “mounting” column to in-
dicate whether the fixture is wall-mounted, surfaced-mounted on the ceiling, or recessed. Alternatively,
this information can be included in the “remarks” column. Also included in this column is information re-
lating to the mounting height above the finished floor, in the case of a wall-mounted lighting fixture, or
any other pertinent data for the proper installation of the fixtures (Figure 9.9).
Electrical general notes are placed on the first and subsequent sheets of the electrical drawings.
They contain items that are common to all electrical items and may also include information regarding
coordination of other trades with the electrical trades
Electrical notes are normally contained on each sheet as required and are relevant to that particu-
lar sheet only. They are also used to give specific location and direction regarding electrical issues.
9.7 PANEL-BOARD SCHEDULES.
Panel-board schedules are generally found on electrical drawings and are used mainly to indicate rele-
vant information on the service-panel boards within the building. A panel-board schedule should provide
sufficient data to identify the panel number (as indicated on the drawings) and the type of cabinet
(whether surface-mounted or flush). It should also provide relevant data regarding the panel main bus
bars and/or circuitbreakers as well as the number and type of circuitbreakers contained in the panel
board and the components fed by each. This type of schedule, however, does not furnish detailed infor-
mation for the individual circuits (e.g., wire sizes or number of outlets on the circuit); this information
needs to be shown elsewhere on the drawing, such as in the plan view or power-riser diagrams.
9.8 MISCELLANEOUS SCHEDULES AND NOTES.
Other types of schedules used depend on office procedure and the type of project in hand. Material
schedules are used usually to list the approximate quantities of materials needed to complete a project.
These schedules are often used for estimating small construction projects such as residential buildings
and should not be taken to reflect the exact amount of materials needed. Material schedules are mainly
used for guidance.
