The title block identifies each sheet in a set of
drawings. (See fig. 1-11.) Generally, the title block is
located at the bottom right comer of the drawing
regardless of the size of the drawing (except for
vertical title block). For further information on the
layout of title blocks, refer to the Engineering Aid 3.
The information provided in the title block is
important information that a Steelworker MUST
understand. The information includes the following:
Name of local activity
Code ID number (80091 NAVFAC)
Size of drawing
Scale of drawing
ABFC drawing number (if applicable)
There are many variations to title blocks.
Depending on the preparing activity (NAVFAC, NCR,
NMCB, etc.), all title blocks should contain the same
information listed above.
A Revision block contains a list of revisions made
to a drawing. The Revision block is located in the
upper right-hand corner. The Revision block can
include a separate PREPARED BY column to
indicate the organization, such as an architectural
engineering firm, that prepared the revision. Like title
blocks, revision blocks can vary in format with each
Graphic scales are located in the lower right-hand
comer of each drawing sheet, with the words Graphic
Scales directly over them. The correct graphic scales
must be shown prominent y on each drawing because,
as drawings are reduced in size, the reductions are
often NOT to scaled proportions. Remember, scaling
a drawing should be done as a last resort.
NOTES are brief, clear, and explicit statements
regarding material use and finish and construction
methods. Notes in a construction drawing are
classified as specific and general.
SPECIFIC notes are used either to reflect
dimensional information on the drawing or to be
explanatory. As a means of saving space, many of the
terms used in this type of note are often expressed as
GENERAL notes refer to all of the notes on the
drawing not accompanied by a leader and an
arrowhead. As used in this book, general notes for a
set of drawings covering one particular type of work
are placed on the first sheet of the set. They should be
