Each of the above divisions is further divided into
sections. You can find a discussion of the required
sections of Division 1 in Policy and Procedures for
Project Drawing and Specification Preparation,
The Division 1 sections,
sometimes referred to as boilerplate, are generally
common to all projects accomplished under a
construction contract. Divisions 2 through 16 contain
the technical sections that pertain to the specific
project for which the spec writer has prepared the
These technical sections follow the
CSI-recommended three-part section format. The
first part, General, includes requirements of a general
nature. Part 2, Products, addresses the products or
quality of materials and equipment to be included in
the work. The third part, Execution, provides detailed
requirements for performance of the work.
Usually, the engineer or spec writer prepares each
section of a specification based on the appropriate
guide specification listed in the Engineering and
Design Criteria for Navy Facilities, MIL-BUL-34.
This military bulletin (issued quarterly by the Naval
Construction Battalion Center, Port Hueneme,
California) lists current NAVFACENGCOM guide
specifications, standard specifications and drawings,
definitive drawings, NAVFAC design manuals, and
military handbooks that are used as design criteria.
As discussed earlier, when writing the specifi-
cations for a project, you must modify the guide
specification you are using to fit the project. Portions
of guide specifications that concern work not included
in the project should be deleted. When portions of the
required work are not included in a guide
specification, then you must prepare a suitable section
to cover the work, using language and form similar to
the guide specification. Do not combine work
covered by various guide specifications into one
section unless the work is minor in nature. Do not
reference the guide specification in the project
specifications. You must use the guide spec only as a
manuscript that can be edited and incorporated into
the project specs.
The preceding discussion provides only a brief
overview of construction specifications. For
additional guidance regarding specification
preparation, you should refer to Policy and
Procedures for Project Drawing
Preparation, MIL-HDBK- 1006/1.
