DRAWINGS
The construction of any structure or facility
is described by a set of related drawings that give
the SEABEEs a complete sequential graphic
description of each phase of the construction
process. In most cases, a set of drawings
shows the location of the project, boundaries,
contours, and outstanding physical features
of the construction site and its adjoining
areas. Succeeding drawings give further graphic
and printed instructions for each phase of
construction.
TYPES OF CONSTRUCTION
DRAWINGS
Generally, construction drawings are cate-
gorized according to their intended purpose. Some
of the types commonly used in military construc-
tion are discussed in this chapter.
PRESENTATION DRAWINGS
The purpose of the PRESENTATION
DRAWINGS is to present the proposed building
or facility in an attractive setting in its natural
surrounding at the proposed site. They often
consist of perspective views complete with colors
and shading. Since presentation drawings are
actually used to sell an idea or design concept,
an EA assigned to the drafting section is rarely
required to develop them.
SHOP DRAWINGS
SHOP DRAWINGS are drawings, schedules,
diagrams, and other related data to illustrate a
material, a product, or a system for some
portion of the work prepared by the construction
contractor, subcontractor, manufacturer, dis-
tributor, or supplier. Product data include
brochures,
illustrations, performance charts,
and other information by which the work will be
judged. As an EA, you will be required to draft
shop drawings for minor shop and field projects.
You may draw shop items, such as doors,
cabinets, and small portable structures (pre-
fabricated berthing quarters, and modifications
of existing buildings), or perhaps you may be
drawing from portions of design drawings,
specifications, or from freehand sketches given
by the design engineer.
MASTER PLAN DRAWINGS
MASTER PLAN DRAWINGS are commonly
used in the architectural, topographical, and
construction fields. They show sufficient features
to be used as guides in long-range area develop-
ment. They usually contain section boundary
lines, horizontal and vertical control data,
acreage, locations and descriptions of existing
and proposed structures, existing and proposed
surfaced and unsurfaced roads and sidewalks,
streams, rights-of-way and appurtenances, existing
utilities, north point indicator (arrow), contour
lines, and profiles. Master plan and general
development drawings on existing and proposed
Navy installations are maintained and constantly
upgraded by the resident officer in charge of
construction (ROICC) and by the public works
department (PWD).
WORKING DRAWINGS
A WORKING DRAWING (also called project
drawing) is any drawing that furnishes the infor-
mation required by the craftsmen to manufacture
a machine part or by a builder crew to erect a
structure; it is prepared from a freehand sketch
or a design drawing. Complete information is
presented in a set of working drawings, complete
enough that the user will require no further
information. Project drawings include all the
drawings necessary for the different SEABEE
ratings to complete the project. These are the
drawings that show the size, quantity, location,
and relationship of the building components.
