Transcriber's note:

For Text: A word surrounded by a cedilla such as ~this~ signifies that
the word is bolded in the text. A word surrounded by underscores like
_this_ signifies the word is italics in the text. The italic and bold
markup for single italized letters (such as variables in equations) and
"foreign" abbreviations are deleted for easier reading.

For numbers and equations: Parentheses have been added to clarify
fractions. Underscores before bracketed numbers in equations denote a
subscript. Superscripts are designated with a caret and brackets, e.g.
11.1^{3} is 11.1 to the third power. Greek letters in equations are
translated to their English version.

Minor typos have been corrected.




PREFACE.


How best to perform construction work and what it will cost for
materials, labor, plant and general expenses are matters of vital
interest to engineers and contractors. This book is a treatise on the
methods and cost of concrete construction. No attempt has been made to
present the subject of cement testing which is already covered by Mr. W.
Purves Taylor's excellent book, nor to discuss the physical properties
of cements and concrete, as they are discussed by Falk and by Sabin, nor
to consider reinforced concrete design as do Turneaure and Maurer or
Buel and Hill, nor to present a general treatise on cements, mortars and
concrete construction like that of Reid or of Taylor and Thompson. On
the contrary, the authors have handled the subject of concrete
construction solely from the viewpoint of the builder of concrete
structures. By doing this they have been able to crowd a great amount of
detailed information on methods and costs of concrete construction into
a volume of moderate size.

Though the special information contained in the book is of most
particular assistance to the contractor or engineer engaged in the
actual work of making and placing concrete, it is believed that it will
also prove highly useful to the designing engineer and to the architect.
It seems plain that no designer of concrete structures can be a really
good designer without having a profound knowledge of methods of
construction and of detailed costs. This book, it is believed, gives
these methods and cost data in greater number and more thoroughly
analyzed than they can be found elsewhere in engineering literature.

The costs and other facts contained in the book have been collected from
a multitude of sources, from the engineering journals, from the
transactions of the engineering societies, from Government Reports and
from the personal records of the authors and of other engineers and
contractors. It is but fair to say that the great bulk of the matter
contained in the book, though portions of it have appeared previously
in other forms in the authors' contributions to the technical press, was
collected and worked up originally by the authors. Where this has not
been the case the original data have been added to and re-analyzed by
the authors. Under these circumstances it has been impracticable to give
specific credit in the pages of the book to every source from which the
authors have drawn aid. They wish here to acknowledge, therefore, the
help secured from many engineers and contractors, from the volumes of
Engineering News, Engineering Record and Engineering-Contracting, and
from the Transactions of the American Society of Civil Engineers and the
proceedings and papers of various other civil engineering societies and
organizations of concrete workers. The work done by these journals and
societies in gathering and publishing information on concrete
construction is of great and enduring value and deserves full
acknowledgment.

In answer to any possible inquiry as to the relative parts of the work
done by the two authors in preparing this book, they will answer that it
has been truly the labor of both in every part.
