INTRODUCTION
This document is the final report of a study conducted by the
Building Research Board's Committee on Assessing the Impact on Federal
Agencies of Use of Building Codes as Design Criteria. This committee met
during a period of about nine months, commencing in May, 1988 to evaluate
suggestions that federal agencies should replace some or all of their
building design criteria with state, local, or national model building
codes.
During the course of the committee's study, the U.S. Congress passed
into law the "Public Buildings Amendment Act of 1988.~2 This act
requires that federal building construction comply, to the maximum extent
feasible, with one of the nationally recognized model building codes.
Recognizing that the implications of this new law may differ substan-
tially from one agency to another, the committee undertook to look beyond
its original charge and to offer guidance on how federal agencies might
best respond to the law's requirements.
Origin of the Suggestions
Most private construction in the United States is regulated by state
or local government-enacted building codes and zoning regulations
intended to protect the safety, health and welfare of building occupants
and the community at large. Individual building owners establish their
own criteria, sometimes extensive, for a building's design, construction,
and operations, but in matters covered by government codes and regula-
tions, the building must meet requirements set by law and ordinance.
Consequently, few private building owners concern themselves directly
with the building characteristics covered by codes, and entrust to their
engineers and architects the responsibility to assure that code require-
ments are met, and these professionals in turn must work with responsible
local officials to assure code compliance.
Building code regulations are adopted by the governing body having
authority to do so in a particular jurisdiction. In most areas of the
United States, local government has been given the major share of that
authority. Some 16 states now exercise broad powers over building, in

the form of statewide codes, and most others impose regulations in such
areas as energy conservation and access for handicapped persons.
Buildings may be subject to additional federal or state regulations,
usually as a condition of funds used in construction of facilities such
as prisons or hospitals.
The majority of these many regulations are contained, directly or by
reference, in the local jurisdiction's official building code.3 The
building codes in many jurisdictions are based on one of the several
model building codes. While historic precedent has led to broad
similarity among building codes in nearby jurisdictions, codes found in
different parts of the country may differ substantially in their format
and substance. Even those jurisdictions using the same basic model code
may introduce differences in the specific provisions of their codes
through their dependence on different editions of the published model
code or their desire to protect the unique interests of their local
community or interest groups.
Federal agencies are exempt from these state and local building
codes (and from zoning laws as well), and are entirely responsible for
all aspects of safety and health in their facilities. As a result, most
of the 30 or more federal agencies with statutory authority to procure
construction and related professional services have included requirements
in their.criteria for design and construction requirements that address
the same concerns as local building codes, but may not apply the same
standards.
In recent years, suggestions have been made that federal agencies
should adopt applicable state or local codes in lieu of their own
criteria.5 The Council of American Building Officials (CABO) has taken
such a stance, for example, as have some local and state government
officials.
Federal policy6 encourages agencies to adopt product standards set
by the private sector when these standards are adequate for the agency's
needs. This policy has led to suggestions that agencies should use

to structure, fire protection, plumbing, electrical systems, and other
elements of buildings.

4Terms such as code and model code have particular meanings that are
sometimes confusing in discussions of these topics. The committee has
adopted the definitions presented later in this chapter.
5The Department of Housing and Urban Development (HUD) has in fact
substantially reduced the bulk of the agency's Minimum Property Standards
(MPS) and now accepts compliance with local codes in determining whether
housing is eligible for mortgage insurance or other assistance under
Federal Housing Administration programs. However, HUD is not an owner of
the resulting buildings and thereby differs substantially from other
agencies being considered here.

national model codes -- upon which almost all local building codes are
based -- in lieu of their own criteria.
Some Key Definitions
No standard terminology is universally accepted for discussion of
building codes and regulations. The committee found that even among
themselves there was a need to establish a consistent set of definitions
of key terms. Drawing primarily upon Standard Terminology of Building
Constructions issued by ASTM (formerly the American Society for Testing
and Materials), the committee adopted the following definitions:
Building -- a shelter comprising a partially or totally enclosed space,
erected by means of a planned process of forming and combining materials.
Buildings serve a variety of functions -- as offices, housing, storage,
or other uses -- that influence the performance characteristics required
of a building.
Building performance -- the behavior of a building in service, generally
described in terms of the ability of the building to support the
functions it serves.
Building life cycle -- an imprecise term of the period of time and course
of events of a building's construction and use. The life cycle may
extend for many years and include significant maintenance, repair, and
alteration activities. For purposes of design and economic analysis, the
life cycle is often defined as the time from completion of a building's
construction until the building is demolished or so completely rebuilt
that it is essentially a new building, typically 30 to 50 years.
Owner's requirements -- the characteristics of a building and the
building 's performances that an owner requires to assure that the
building serves the purpose for which it is intended. Owner's
requirements may depend on the owner's particular interests or mission,
including whether the owner expects to retain ownership beyond completion
of construction and to rent the building to others or to use it for his
own activities.
Criterion --an established precedent, rule, measure, or code upon which a
decision is based.
Standard -- a definite rule or measure adopted by recognized authority as
a basis for judging quality or quantity. Standards, termed "voluntary,"
may be promulgated by professional organizations, governmental agencies,
trade groups, or independent expertise, and may be adopted in owners'
criteria or codes. The committee estimates that more than 125 such

groups produce building standards. Among the more widely adopted
standards in building are those developed by the American National
Standards Institute (ANSI), ASTM (formerly American Society for Testing
and Materials), the National Fire Protection Association (NFPA), the
American Institute for Steel Construction (AISC), and the American
Concrete Institute (ACI). Such standards may also be termed '"consensus''
or ''industry" standards. Standards applicable to buildings may also be
established by legislation, for example with respect to energy conser-
vation, air quality, or exposure to hazardous materials, or by general
government regulations. These standards may be termed ''statutory
standards."
Design criteria -- the set of criteria established by a building owner as
factors for determining whether a building's design and construction are
acceptable. Design criteria are based on owner's requirements and
applicable government regulations. These criteria, also termed "owner's
criteria," may be adopted directly by the actual building owner or
indirectly by the owner's selected designer. Many owners and managers of
large numbers of buildings (such as major industrial firms, real estate
developers and managers, and federal agencies) have assembled and
formalized their building design criteria into design guideline docu-
ments or manuals. Design criteria generally incorporate a range of
criteria and standards intended to assure acceptable performance of a
building, which include implicitly or by reference applicable building
codes. However, owner's criteria include many items not covered by codes
and may include standards that exceed levels adopted in building codes.
Code -- a collection of laws, regulations, ordinances, or other statutory
requirements adopted by government legislative authority. Some profes-
sional and trade organizations have published advisory documents that
they term ''codes'' (see also model code) , but these documents do not have
the force of law (unless adopted by a government body) and therefore are
really collections of promulgated cri teria and s tandards , rather than
codes.
Building code -- a code applicable to buildings, adopted by a government
body and administered with the primary intent of protecting public
safety, health, and welfare; generally includes both review and approval
process requirements and specific technical standards.
Model code -- a proposed code that is established within the procedural
context of a group of knowledgeable people, often working within the
framework of a professional organization, and is designed for adoption by
responsible governmental authority. There currently are three major
organizations that have developed model codes that have been adopted --
often with modification -- as the basis for building codes in various
jurisdictions: the Southern Building Codes Congress International
(SBCCI), the International Conference of Building Officials (ICBO), and
the Building Officials and Codes Administrators International (BOCA).
There are other organizations that promulgate model codes that typically
are limited in scope.
