Special Inspections
Valuable tool of the building code
By: Paul Becker, P.E. and Jim Landau, P.E.
The nature of construction has evolved and changed greatly since the
turn of the century, not unlike other industries which serve the needs
of a capitalist society. New technologies and new materials are constantly
introduced to offer lighter, more efficient structures which reduce material
costs and offer the possibility of greater spans and larger volumes. With
the rapid changes in technology and mounting requirements prescribed by
building codes, structural systems for buildings have become more sophisticated
and in many cases, quite intricate.
The BOCA Building Code, widely used in Maine, recognizes that a fundamental
change has taken place in the building industry and that the need for
structural inspections has never been more critical. The 1996 edition
of the BOCA code requires the owner of a project to provide Special Inspections
of the structural portions of a construction project. These inspections
are to be performed specifically on structural components and assemblies
used within a project to verify their as-built compliance with design
documents. Special Inspections is a quality assurance procedure for the
benefit of the owner and the public.
Although the intent of the code is clearly to assure structural safety,
current terminology in the code permits someone other than the Structural
Engineer of Record (registered engineer responsible for the structural
design of the building) to develop and administer the Special Inspections.
Without the direct and continued involvement of the Structural Engineer
of Record during the special inspection process, sufficient assurance
of structural safety cannot be provided. The U.S. House of Representatives
investigated the problem of structural failures in the United States and
issued House Report 98-621 which stated in part: "The structural
engineer is one of the most important individuals in the construction
process. His regular presence on the construction site can prevent errors
which lead to structural failures and his absence can permit serious mistakes
to go unnoticed and uncorrected. The structural engineer is the person
most likely to observe defects on-site, for it is he and his associates
who make the calculations and review the project drawings as the construction
design is developed. The structural engineer is thus intimately familiar
with the details of the project when actual fieldwork begins; no other
person involved in the process shares this familiarity....". Clearly
code provisions should be revised to clarify and strengthen the role of
the Structural Engineer of Record.
Furthermore, although the BOCA Code mandates special inspections, compliance
is extremely low. The State of Maine has not adopted a State Building
Code. Without a single source code, many towns and municipalities are
using building codes which are 10 years old. Those which have adopted
more recent codes are not enforcing them. Without enforcement by code
officials, owners are unwilling to pay for special inspections although
the cost of conducting the Special Inspections is estimated at only one-half
of one percent of the construction cost. The benefit of the additional
cost is increased structural safety and a reduction in repair and maintenance
costs over the life of the structure. The question becomes, with the instrument
of Special Inspections available, how can we as citizens not demand that
our public safety be protected to the highest degree possible. We must
encourage Building Officials to execute their assigned duties by requiring
compliance with BOCA Section 114 and 1705. There should be a Statement
of Special Inspections on file for that new school or new office in your
neighborhood. See for yourself if there is compliance. Its right,
its smart and its time.
