FOREWORD
The development and use of abbreviations, acronyms and symbols, as a form of shorthand to convey
information, has grown enormously during the past half century. It has even been described as one of the fastest
growth industries in the world today. Designed to provide shortcuts in written material, drawings and speech,
abbreviations and symbols have proliferated in all languages. In the English language alone there are hundreds
of dictionaries and books devoted entirely to abbreviations, acronyms and symbols and their decoding and
encoding. Governments and their bureaucracies on one hand, and scientists and technologists on the other, have
been the main originators of new abbreviations and acronyms to replace lengthy terms with representative and
often catchy “miniwords”. Modern English even includes some words that started out as abbreviations or
acronyms. One of the best examples is the word laser which is a 5-letter abbreviation for the seven-word term
l(ight) a(mplification by) s(timulated) e(mission of) r(adiation), thus replacing 55 letters and spaces. Great efforts
have been made to standardize language-independent symbols internationally, for example symbols for units of
measurement, notation for physical quantities, chemical symbols, and other technical information symbols.
Contemporary literature, drawings and conversations continue to be filled with numerous, often undefined,
abbreviations, acronyms, appellations, contractions, initialisms, and a variety of letter-based and graphical
symbols as communication shortcuts. All too often readers, viewers or listeners have problems in interpreting
meanings expressed in abbreviated form and, at times, this can lead to real misunderstandings or even costly
errors. Not surprisingly, the shorthand used by one profession, discipline or industry is frequently completely
baffling to others outside that area.
The building and construction environment has always had a penchant for the use of shorthand in
communication, from the colloquial use of “reo” for reinforcement, “ag pipe” for agricultural pipe, and “RSJ”
for almost any kind of steel beam to a multitude of abbreviations and symbols on drawings and in text.
Abbreviations and symbols are even included in the titles of some Australian Standards, with typical examples
such as LP, PB, PVC, SI and UPVC, and the symbol kV.
Throughout its seventy-year history, Standards Australia has endeavoured to bring about the rationalization
of products, processes and services and establish quantitative as well as qualitative standards suitable for
nationwide adoption. In that undertaking, many standards-writing committees have acted in good faith, although
at times unilaterally, by contributing extensively to the catalogue of abbreviations and symbols. In line with other
efforts to rationalize and simplify communication, it is an opportune time for a nationally recognized “standard”
document on the use and interpretation of abbreviations and symbols in building and construction. Standards
Australia has embarked on the first stage of such a project by arranging for the extraction, from some nine
hundred national standards, of those abbreviations, acronyms and symbols that are relevant to the building and
construction industries. The extracted material has been presented in a form suitable as a desk-reference
handbook.
While there is a multitude of other English-language abbreviations, acronyms and symbols for use in building
design, construction, and related product manufacture or testing, it was decided that the first edition of this
handbook should concentrate entirely on abbreviations and symbols found in Australian Standards. Therefore,
every entry in the handbook can be traced back to relevant Australian Standards and, except for the listing of
metric (SI) unit symbols, all entries are accompanied by a cross-reference to the source standard or standards
unless there were too many different standards to allow individual identification. In a few instances, more than
one abbreviation or symbol may be found in which case preferences are indicated by showing the less preferred
form in parentheses. Guidelines for the development and use of abbreviations, and good practice in document
preparation, are also included. The handbook was prepared for Standards Australia by Hans J. Milton, B.Arch.
(Hons), M.Bdg.Sc., M.B.A., F.R.A.I.A.
This handbook is envisaged as a dynamic document and all constructive comment on its layout and contents
are welcome. Suggestions on additions or modifications to the range of abbreviations and symbols for
construction can be made in relation to individual standards or the collection presented in this handbook.
