PLANS, SPECIFICATIONS, AND COLOR CODING
LEARNING OBJECTIVE: Interpret basic plans, drawings, and specifications in
construction operations. Recognize crew leader responsibilities and safety color-
In the day-to-day work as a Utilitiesman, you will
be installing, assembling, inspecting, and
troubleshooting many types of utility systems. To do
these jobs properly, you must read and interpret plans
and drawings. You may also have to read specifications
that contain additional information on the details of
construction and installation. Plans and specifications
help you in doing the job correctly and safely.
After studying this topic, you should be able
to read and interpret simple drawings and sketches
as well as using the specifications to help you with
more complex plans. Additionally, you should be
able to draw simple shop drawings and specify the
hazards associated with each color code for piping
and compressed gas containers.
LEARNING OBJECTIVE: Identify the
arrangement of a set of project blueprints and
types of plans and drawings.
You will be working with several types of plans
and drawings. These may range from simple shop
drawings and sketches, made perhaps by your
immediate supervisor, to construction blueprints
created by engineers. For the most part you will be
working with plans created by architects and
engineers. In Seabee construction, a complete set of
plans for a project consists of civil, architectural,
structural, electrical and mechanical plans, or
drawings. You will be spending the majority of your
time with mechanical drawings, but you will need all of
these plans together to obtain a full picture of your part
of that project and how to accomplish it.
Civil plans, or site plans, encompass a variety of
drawings and. information. They furnish essential data,
such as land contours, roads, utilities, trees, structures,
site preparation and development, and significant
physical features, on or near the construction site (fig.
Architectural plans show the architectural design
and composition of a building. They include floor
plans, exterior elevation plans, and door and window
schedules (fig. 1-2).
Structural plans show the support of the building or
structure, including walls, columns, beams,
foundation, roof, and deck slab. They also show their
relationship to each other (figs. 1-3 and 1-4).
Electrical plans contain the electrical distribution
system plans, interior wiring drawings, and electrical
component schedules for a building, or structure. They
show wiring circuits, light switches, receptacles, light
fixtures, and equipment (fig. 1-5).
Mechanical plans include layouts and details for
systems of plumbing, heating, ventilating, air
conditioning, and refrigeration (fig. 1-6). These
systems vary, depending on whether they are for a
permanent installation with the most modern fixtures
and equipment or for a temporary installation where
less complex equipment is used. Whatever the job, you
