4. Masonry includes concrete masonry units, brick, stone, and mortar.

5. Metals include such items as structural steel, open-web steel joists, metal stud and joist systems, ornamental metal work, grills, and louvers. (Sheet-metal work is usually included in Division 7.)

7. Thermal and Moisture Protection includes such items as waterproofing, dampproofing, insulation, roofing materials, sheet metal and flashing, caulking, and sealants.

8. Doors and Windows include doors, windows, finish hardware, glass and glazing, storefront systems, and similar items.

9. Finishes include such items as floor and wall coverings, painting, lathe, plaster, and tile.

10. Specialties include prefabricated products and devices, such as chalkboards, moveable partitions, fire-fighting devices, flagpoles, signs, and toilet accessories.

11. Equipment includes such items as medical equipment, laboratory equipment, food service equipment, kitchen and bath cabinetwork, and counter tops.

12. Furnishings include prefabricated cabinets, blinds, drapery, carpeting, furniture, and seating.

13. Special Construction includes such items as prefabricated structures, integrated ceiling systems, and swimming pools.

14. Conveying Systems include dumbwaiters, elevators, moving stairs, material-handling systems, and other similar conveying systems.

15. Mechanical Systems include plumbing, heating, air conditioning, fire-protection systems, and refrigeration systems.

16. Electrical Systems include 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 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 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 and Specification Preparation, MIL-HDBK- 1006/1.
