written data, another drawing, or any combination of
these. Any error or omission of information in these
sources will result in inaccuracies in the drawing;
therefore, the first check is to make sure that the source
accurately provides everything needed to make the
drawing. Editing means that you are inspecting the
drawing to make sure that the procedures and
conventions prescribed in relevant NAVFAC
publications and military standards are followed. It
might be said that editing begins as soon as drawings
begin-meaning that you must constantly edit drawings
to ensure that proper procedures and conventions are
followed at the time the drawings are made.
When checking and editing a detail drawing, the
checker ALWAYS uses a print of the drawing, rather
than the original. That way, any corrections that need to
be made can be marked with a colored pencil or pen on
the print without disturbing or destroying the original.
The detail drafter then uses the marked-up print to make
corrections to the original drawing. After all of the
corrections have been made, the checker compares a
print of the corrected drawing with the originally
For a thorough job of checking and editing, you
should first make an overall check with the following
questions in mind:
1. Does the drawing reproduce well? Any poorly
defined or weak line work and lettering must be
2. Does the size and format of the drawing conform
to the MIL-HDBK-1006/1 requirements for Naval
Facilities Engineering Command (NAVFACENG-
COM) drawings? As specified in that publication, the
project drawings should be prepared on flat C-, D-, or
F-size paper. It also specifies that a vertical title block
format is mandatory for D-size drawings and optional
for F-size. Examples of both horizontal and vertical
format title blocks can be found in MIL-HDBK-1006/1.
3. For a set of drawings, is a different drawing
number assigned to each sheet and are all of the drawing
numbers correct? Is the set of drawings arranged in the
correct order as specified in MIL-HDBK-1006/1. That
is, are they arranged as follows:
a. Title sheet and index of drawings (only for
projects containing 60 or more drawings).
b. Plot and vicinity plans (including civil and
utility plans). This sheet should include an index for
c. Landscape and irrigation.
f. Mechanical (heating, ventilating, and air
i. Fire protection.
If the overall check is satisfactory, proceed with
more detailed questions, such as the following:
1. Is the method of projection appropriate?
2. Are the views shown the minimum number
required to show all the data?
3. Are sectional views constructed correctly and
is the section lining correct?
4. Are line conventions and symbols consistent
with the requirements of appropriate and current
standards? Are all symbols (especially nonstandard
ones) explained in a legend?
5. Are proper scales used for the drawing and are
the scales shown? Appropriate scales for construction
drawings are as follows:
a. Floor plans and elevations: 1/4", 3/16", 1/8",
or 1/16" = 1´ O".
b. Architectural details: 3/4", 1 1/2", or
3" = 1´ 0´.
c. Molding sections and similar details: full
scale or half scale.
d. Mechanical and electrical details: 3/8", 1/2",
3/4", or 1" = 1´ 0´.
e. Structural details: 3/8", 1/2", 3/4", or
1" = 1´ 0´.
f. Structural erection drawings (such as
structural floor and roof framing plans): 1/8" or
1/16" = 1´ - 0".
g. Site (plot) plans: 1" = 10´, 20´, 30´, 40´, 50´,
60´, 100´, or 200´.
h. Utility plans: 1" = 20´, 30´, 40´, or 50´.
6. Are graphic scales shown as required by
7. Do the dimensions agree with those shown in
the data source? Does the sum of partial dimensions
equal the overall dimensions?
