PREFACE TO FIRST LDITION
Tuss graphic and diagrammatic assembly of data, standards, and
information is for the use of those concerned with architecrore, building,
and their allird fields, This work was started some two yeers ago because of
the very definite lack of any convenient, concentrated source of such
matecial
To translate the facts most quickly for those accustomed to making
aud using drawings, we cliese the graphic form of preseatation, purposely
devoid of all design in the decorative sense. Those trained (s prasp a drawing
2t a plance can find thelr desired informarion immediately. Therefore rables
and eharts axc used only when such a medium is obvously the more concise.
The progression of the book folliws the wsual building constravtion
procedore from fonndation to furnitare, with those mosr-nceded miscclla-
neous dute sheets placed 2t the end
The nscfulness of the book is dependent vpon the nse given o the indesx,
hence irems have heen cross-indexed in several ways. Tor instance. βTead-
e may also be found under e captions, β Downspout,β Drains,ββ Deain-
2gs, Roof," * Raofing, Teaders,β *Copper, Teaders,β βZine, Leaders,β ete
An effort bas been made to present material that is standard where any
siandavds exist: if not, acceptrd methods or customary peactice is shawn.
The purprse s Us present ahe cure ur skelecan data usefol [or urcher develop-
ment, design, or impunvemene. We hape that the macesial will serve as a
yoint of deparrure for farther study or qualification
The material has been culled fiaun such a variery of souces that it is
often diffcult tn trace the origin. The architecrural hand-honks, reference
books, and maguzines have been carefully combed for data, Trade associa-
tions, the United States Bureau of Standards, the Amedican Standards
Associution, the Board of Undenwriters, have been consilred nd their
publicitions summarized where relevant. Trade journals, catalogucs,
βSweer's,β have been frecly consulted
βThe sheets were presented in many cases to those best qualified to give
constructive criticism in thefr field, and after surh coticism, changes and
additions were mude thereon, Whenever defiuite govenuoene or trade
standards have been used a note so stating appears at the hotront of the
shece. Were engineers ar others checked the material or furnished calcula-
tious 1heir uames arc appended 1o the sheet.
We veish to thank the ma fations, organizations, individaals, and
povernmene officials who have so generously given us their ussistance and
advice, without which this wark would nor exist
