Preface to the Third Edition
The major reason for this third edition, besides updating costs and
other information, is the new building codes—the 2000 International
Building Code (and the very similar NFPA 5000 Building Code). With
the IBC, a very good thing has happened. The three model codes in the
United States have come together to produce one national model code
(even though it is called “international”). The bad thing, to my think-
ing, is that it has grown in size and complexity by a factor of 10. I chal-
lenge anyone to read it (if you can), as I did, and not come to the same
conclusion. It is very difficult to grasp, and I believe it will become dif-
ficult to enforce. This will put anyone associated with it in jeopardy of
being accused of not adhering to or enforcing the law. The NFPA code,
though a little more user friendly, is not much better. I believe that
when laws become too complex and voluminous people simply no
longer pay attention to them. It should not be that way.
Therefore, I urge all design professionals and all others dealing with
building construction or code enforcement to solicit their professional
associations and other organizations to lobby for a simpler code—now!
K.I.S.S. (“Keep it simple, stupid”) is the answer.
How to Use This Book
The concept of this book is that of a personal tool that compacts the
20% of the data that is needed 80% of the time by design professionals
in the preliminary design of buildings of all types and sizes and of the
spaces between.
This tool is meant to always be at one’s fingertips (open on a drawing
board or desk, carried in a briefcase, or kept in one’s pocket). It is never
meant to sit on a bookshelf. It is meant to be used every day!
Because design professionals are individualistic and their practices
are so varied, the user is encouraged to individualize this book over
time, by adding notes or changing data as experience dictates.
The addition of rough construction costs throughout the book (mak-
ing this type of handbook truly unique) will date the data. But building
laws, new technologies, and materials are changing just as fast. There-
fore, this book should be looked on as a starter of simple data collection
that must be updated over time. New editions may be published in the
future. See p. 43 for more information on costs.
Because this book is so broad in scope, yet so compact, information
can be presented only at one place and not repeated. Examples of how
to use the information are provided throughout. Information is pre-
sented in the form of simple ratios or coefficients that replace the need
for commonsense judgment.
The whole book is laid out in checklist format, to be quickly read and
checked against the design problem at hand.
Where is shown, refer to p. 665 for further explanation of refer-
ences.
“Notes” pages appear throughout, on which the user is encouraged to
keep further information in the form of notes or sketches.
This book is not a substitute for professional expertise or other books
of a more detailed and specialized nature, but will be a continuing
everyday aid that takes the more useful “cream” off the top of other
sources.
