General notes may also refer to all of the notes

MAIN DIVISIONS OF
Generally, working or project drawings may
be divided into the following major categories:
civil, architectural, structural, mechanical, elec-
trical, and fire protection. In SEABEE construc-
tion, however, the major categories most
commonly used are as follows: CIVIL, ARCHI-
TECTURAL, STRUCTURAL, MECHANICAL,
and ELECTRICAL sets of drawings.
Regardless of the category, working drawings
serve the following functions:
. They provide a basis for making material,
labor, and equipment estimates before construc-
l They give instructions for construction,
showing the sizes and locations of the various

between the different ratings.
l They complement the specifications; one

Civil working drawings encompass a variety
of plans and information to include the following:
Site preparation and site development
Rigid and flexible pavements for roads and
Environmental pollution control
