FEDERAL AND MILITARY
SPECIFICATIONS
Federal specifications cover the characteristics of
materials and supplies used jointly by the Navy and
other government agencies. Federal specifications do
not cover installation or workmanship for a particular
project but specify the technical requirements and tests
for materials, products, and services. Federal
specifications dictate the minimum requirements
acceptable for use of all federal agencies. The
engineering technical library should contain all of the
commonly used federal specifications pertinent to
Seabee construction.
Military specifications are those specifications that
have been developed by the Department of Defense.
Like federal specifications, they also cover the
characteristics of materials. They are identified by MIL
preceding the first letter and serial number, such as
MIL-L-19140C (lumber and plywood, fire-retardant
treated).
Your main concern will be with project
specifications. Even if you do not see them, you should
know that they exist and what kind of information they
include.
PROJECT SPECIFICATIONS
Construction drawings are supplemented by
written project specifications. Project specifications
give detailed information regarding materials and
methods of work for a particular construction project.
They cover various factors relating to the project, such
as general conditions, scope of work, quality of
materials, standards of workmanship, and protection of
finished work. The drawings, together with the project
specifications, define the project in detail and show
exactly how it is to be constructed. Usually, any set of
drawings for an important project is accompanied by a
set of project specifications. The drawings and project
specifications are inseparable. The drawings indicate
what the project specifications do not cover; and the
project specifications indicate what the drawings do not
portray, or they clarify further details that are not
covered or amplified by the drawings and notes on the
drawings. Whenever there is conflicting information on
the drawings and project specifications, the project
specifications take precedence over the drawings.
The general requirements are usually the first
specifications listed for the structure, stating the type of
foundation, character of load-bearing members (wood
frame, steel frame, or concrete), type or types of doors
and windows, types of mechanical and electrical
installations, and the principal function of the building.
Next follows the specific conditions that must be
carried out by the constructors. These are grouped in
divisions under headings applying to each major phase
of construction, such as the following typical list of
divisions:
1. GENERAL REQUIREMENTS
2. SITE WORK
3. CONCRETE
4. MASONRY
5. METALS
6. CARPENTRY
7. MOISTURE CONTROL
8. DOORS, WINDOWS, AND GLASS
9. FINISHES
10. SPECIALTIES
11. EQUIPMENT
12. FURNISHINGS
13. SPECIAL CONSTRUCTION
14. CONVEYING SYSTEMS
15. MECHANICAL
16. ELECTRICAL
17. EXPEDITIONARY STRUCTURES
Sections under one of these general categories
sometimes begin with general requirements for that
category. For example: under DIVISION 16.—
ELECTRICAL, the first section might read as follows:
16.—0l.—General
Requirements.—
Electrical installation must conform to the
requirements of the National Electrical Code©.
This includes all temporary work and the
complete installation.
The service entrance
equipment must conform to the requirements of
the local electric utility company if it is the
source of electric power for the building or
facility.
Subsequent sections under DIVISION 16.—
ELECTRICAL would specify various quality criteria
and standards of workmanship for the different types of
electrical installation work; for example:
