Setting the Standard for U.S. Building Codes
ICC Partners with ASTM to Improve Safety and Economy
by Mark Johnson
ASTM standards account for almost one-half of the standards referenced
in the building code regulations newly consolidated into the International Codes. Recently, in cooperation with ASTM, the International Conference of Building Officials (ICBO) published a compilation of all ASTM standards cited in
the I-Codes. ICBOs Mark Johnson writes about the importance of
standards to the I-Codes and the benefits of this new cost- effective
compilation.
Citizens of the United States witnessed an historic moment earlier
this year when the International Code Council® (ICC) released
the nations first fully coordinated and compatible set of building
code regulations. Six years in the making, the International Codesor
I-Codes, as they are often calledrepresent over 200 years of
combined experience on the part of the nations three model code
groups.
Founded in 1994 by Building Officials and Code Administrators,
International, Inc. (BOCA), the International Conference of Building Officials (ICBO), and
the Southern Building Code Congress International, Inc. (SBCCI), ICC was given a clear mandate to provide a better alternative
to the nations regionally-based regulatory systems by developing
a single, cohesive set of model building codes. While incorporating
the latest in building safety concepts, the I-Codes are founded
on the strengths of the three regional codes: BOCAs National
Building Code (NBC), SBCCIs Standard Building Code (SBC) and
ICBOs Uniform Building Code (UBC). Together, these codes have
assured the safety of our nations structures and their occupants
for the past 70 years.
Prior to the release of the I-Codes, nearly every state used one
of the three regional codes as the basis for its building regulatory
system. Notable exceptions were New York and Wisconsin, which
developed their own state codes, but even that is about to change
with the release of the I-Codes. Both states have reviewed the
I-Codes and have expressed the intention of adopting many of the
codes that make up the 11-volume set.
Codes and Standards
The ICC and its founding members have not been alone in their
efforts. Standards significantly support a building code by providing
the considerable expertise of individuals who participate in specialized
standards-writing activities, and the model codes have relied
heavily on the use of referenced standards since the first edition
of the UBC was published in 1927. With the issuance of the I-Code
family and its flagship volume, the International Building Code®
(IBC), reliance on standards has increased more than tenfold.
Of the nearly 500 standards referenced in Chapter 35 of the 2000
IBC, nearly 50 percent were developed by ASTM. The importance
of these standards is too often overlooked by users of building
codes.
On one hand, building codes are a set of regulations created for
the purposes of adoption and enforcement through the appropriate
local or state legislative and administrative processes. Standards,
on the other hand, are generally a set of requirements or conditions
to which a product or material must conform.
The standards promulgated by ASTM that are referenced in building
codes usually apply to engineering or testing procedures. They
normally contain definitions of terms, classifications of components,
delineations of procedures, specifications of dimensions, and
descriptions of fit and measurement size, as well as measurements
of quality in the description of materials, products, and systems.
The quality of a building product is covered by material standards;
the design of a product is covered by engineering standards. Testing
standards apply to methods for determining the performance quality
of materials or assemblies. Such testing often yields numerical
data for use in the comparison of one material or assembly to
another.
The importance of voluntary consensus standards cannot be understated.
Until they are adopted, building codes have no basis in law and
are much like any other standards that may or may not be referenced
by the designer of a building. It is critical to bear in mind,
however, that the codes typically contain a provision that mandates
simultaneous adoption of a series of applicable referenced standards.
Section 102.4 of the 2000 IBC, for example, states that codes
and standards referenced in this code shall be considered part
of the requirements of this code to the prescribed extent of each
such reference. While the IBC clearly states that the code takes
precedence, should conflicts or differences arise between the
language of the code and that of a referenced standard, this provision
in no way diminishes the fact that the referenced standards have
become, through their inclusion in the codes, as legally enforceable
as the code itself.
Fairness and Safety
In a market-driven society, manufacturers are often pitted against
one another in a quest to win over the hearts and minds of consumers.
The building industry is a particularly competitive one, with
manufacturers of both similar and alternative materials competing
head-to-head for a share of construction spending. If standards
like those produced by ASTM did not exist to support the building
codes, the quality of building products and materials could degenerate
to dangerously low levels. By setting standards and benchmarks
for quality, a level playing field is maintained while competitionthe
hallmark of our free enterprise systemis preserved. A grouping
of manufacturers, consumers, trade associations, or agencies can
develop a standard to suit its own purposes or aims, but only
when a standard is developed in accordance with clear-cut rules
of procedure and openness of process does it earn the stature
necessary for regulatory reference in building codes.
Codes and standards also help to neutralize powerful economic
entities wishing to preserve their hegemony by erecting barriers
to entry into the markets they serve. Section 104.11 of the 2000
IBC allows for alternative materials, design, and methods of construction
and equipment, subject to the approval of the building official.
A Silver Lining for Code Officials
At a cost in the thousands of dollars, the expense of acquiring
a complete, up-to-date set of all the standards referenced in
the IBC has proved challenging for the many jurisdictions whose
building departments budgets are already stretched to the breaking
point. Maintaining a complete set of referenced standards is an
outright impossibility in the vast majority of smaller jurisdictions.
In recognition of these challenges, ICBO has developed a book
under a special licensing agreement that collects all of the ASTM
standards adopted by reference in the 2000 IBC. Entitled the 2000
International Building Code ASTM Referenced Standards, the document
contains nearly half of all the standards cited in the IBC and
covers information on such topics as adhesives, cement, concrete
and concrete aggregates, fasteners, fire standards, wood, fire-resistance
testing, and many other topics.
The 2000 International Building Code ASTM Referenced Standards
is easily the most comprehensive document of its kind distributed
by any model code organization today, and ASTMs leadership in
partnering with ICBO to produce the cost-effective volume has
met with widespread approval from the code-enforcement community.
Conclusion
The ultimate objective of a modern building code is to coordinate
an extensive amount of information into an intelligible, structured
and responsive system that promotes the health, property, safety,
and general welfare of the public. The publication of the IBC-ASTM
Referenced Standards goes a long way toward accomplishing these
goals and is just one example of how ASTM and ICBO are working
together to set the standard for our nations model building code
system. //
