partitions at the particular floor level. It also shows
the number, dimensions, and arrangement of the
rooms, the widths and locations of doors and
windows, and the locations and character of
bathroom, kitchen, and other utility features. You
should carefully study figure 2-12. In dimensioning
floor plans, it is very important to check the overall
dimension against the sum of the partial dimensions
of each part of the structure.
Elevations
The front, rear, and sides of a structure, as they
would appear projected on vertical planes, are shown
in elevations. Studying the elevation drawing gives
you a working idea of the appearance and layout of
the structure.
Elevations for a small building are shown in
figure 2-13. Note that the wall surfaces of this house
will consist of brick and the roof covering of
composition shingles. The top of the rafter plate will
be 8 feet 2 1/4 inches above the level of the finished
first floor, and the tops of the finished door and
window openings 7 feet 1 3/4 inches above the same
level. The roof will be a gable roof with 4 inches of
rise for every 12 inches length. Each window shown
in the elevations is identified by a capital letter that
goes with the window schedule (which we’ll discuss
later in this chapter).
Framing Plans
Framing plans show the size, number, and
location of the structural members (steel or wood) that
make up the building framework. Separate framing
plans may be drawn for the floors, walls, and roof.
The floor framing plan must specify the sizes and
spacing of joists, girders, and columns used to support
the floor.
When detail drawings are needed, the
methods of anchoring joists and girders to the
columns and foundation walls or footings must be
shown. Wall framing plans show the location and
method of framing openings and ceiling heights so
that studs and posts can be cut. Roof framing plans
show the construction of the rafters used to span the
building and support the roof. Size, spacing, roof
slope, and all details are shown.
FLOOR PLANS.— Framing plans for floors are
basically plane views of the girders and joists. Figure
2-14 is an example of a typical floor framing plan.
