drapery, carpeting, furniture, and seating.
13. Special Construction. Such items as
prefabricated structures, integrated ceiling systems, and
swimming pools.
14. Conveying Systems. Dumbwaiters, elevators,
moving stairs, material-handling systems, and other
similar conveying systems.
15. Mechanical Systems. Plumbing, heating, air
conditioning, fire-protection systems, and refrigeration
systems.
16. Electrical Systems. Electrical service and
distribution systems, electrical power equipment,
electric heating and cooling systems, lighting, and other
electrical items.
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,
MIL-HDBK-1006/1. The Division 1 sections,
sometimes referred to as “boilerplate”, are generally
common to all projects that are 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 specification. 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.
Guidance
Usually, the engineer or spec writer prepares each
section of a specification based on the appropriate guide
specification listed in the most recent edition of
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 specifica-
tions for a project, you must modify the guide
specification you are using to fit the project. Portions of
guide specifications that concern work that is not
included in the project will 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 MIL-HDBK-1006/1.
