This first edition of Construction Cost Analysis and Estimating provides the latest principles and techniques
for the evaluation of construction design. It is not a book about estimating only. Analysis and estimating must
abide together, and the one must precede the other. It is this emphasis that makes this text different.
The book begins with four chapters devoted to analysis of labor, material, accounting, and forecasting. Then
estimating is developed, and methods, work, and project chapters are given. An owner or contractor is concerned
with bid assurance, analysis, and contracts and ethics, and these chapters are provided. This book organization
develops the principles in a systematic way.
With the increasing importance of design over rote skills in contemporary construction courses, this text can
be used for a variety of teaching situations: for lecture only, for lecture with a laboratory menu, or with professional
mentoring with business, and with developed field trips. Courses that couple to on-line live or delayed video instruction
can use this text, as the author has personal experience with these delivery modes. Further, lifelong learning
programs for the professional in either formal or informal settings can use the text.
Academic requirements for this book/course may vary, and we believe that the text is suitable for a number of
teaching approaches. It has been written to appeal to engineering/technology/construction management settings.
The student needs a mathematical maturity of algebra and introductory calculus.
The instructor will notice internet requirements that search for information and apply it in practical contexts.
We provide internet addresses for numerous assignments. (Regrettably, these addresses may change from time to time.)
In the interactive environment of teaching, this book is a part of modern courseware. Word-processing and spreadsheet
skills are assumed, and some CAD ability is always helpful. It would seem that the student must have access to
a computer, and system requirements would be typical of more advanced personal or Pentium computers.
Various academic levels and backgrounds are appropriate, and the instructor find this text suitable to a variety
of teaching styles. The author attempts to rove the instructor in the leadership of many exercises, calling on
you, the instructor, to localize the assignments to your construction needs.
The book has more material than can be covered in one semester or quarter and thus chapters and sections can
be selected to meet the objectives of each c1« Chapter order can be adjusted. If the students already have
an understanding of statistics, then Chapter 5 material can be excluded, for example. Other sections can dropped,
depending on student preparation and course objectives. Some sections u identified as "Optional," allowing
instructor selection. The instructor will find that the text is versatile.
This text has a range of difficulty for Questions, Problems, More Difficult Problems, Practical Applications,
and Case Studies. Throughout the text, the author has tempted to give the instructor opportunity for outcomes evaluation
of student woe with these many exercises.
There are 124 Questions in the eleven chapters. They are qualitative and require back-reading and a response
of a few sentences for a thoughtful reply.
We stress construction as a design activity; therefore, the 237 Problems and 48 More Difficult Problems request
computations or sketches. Whenever the student is asked to prepare open-ended designs, much learning occurs. The
Problems have levels of difficulty.
We want the Problems and the More Difficult Problems to be tractable, either with calculator or spreadsheet,
where the emphasis is on teaching concepts. It is no our desire to cause excessive computation, which is so prevalent
in construction problems. Thus, this text ignores software encyclopedias that are found in construction for estimating
designs. Those software applications restrict the learning of principles. Nor do we give much attention to the
minutia of extensive take-off practices, as those temporal trade details can be learned on the job, if necessary.
There is an end-of-chapter addition, which we call Practical Application. The purpose of the Practical Application
is to uncouple the student from books, libraries. and the classroom. As will be seen throughout the book, Practical
Applications introduce the student to experiences in the real world. For example, they encourage; field trips and
communication through the internet to engineers, technologists, and other construction professionals. The instructor
will appreciate this experiential approach, allowing him or her to use Practical Applications in exciting ways.
The end-of-chapter Case Studies are open ended, perhaps having several solutions. Students are often disturbed
by this peculiarity, but instructors recognize that construction courses are unlike calculus courses with their
singularity of answer.
The book contains Picture Lessons�they describe important historical contributions of civil engineering and
construction. It is important that students have an appreciation of the grand heritage of our profession.
For the instructor, a comprehensive Solutions Manual is available. This manual can be requested from the Prentice
Hall college representative or from Prentice Hall directly.
The author is grateful to many people. Their advice and information have made this a much better text. In writing
a book of this magnitude, the author is aware that friends and colleagues are hidden but very important advisers.

Summary
The most current guide of its kind on the market, this essential book for today's construction managers and
engineers provides the latest principles and techniques for the evaluation of construction design by presenting
a balanced and cohesive study of construction cost analysis and estimation. Begins with four chapters on the analysis
of labor, material, accounting, and forecasting--then systematically segues into the area of estimating, with in-depth
discussions on how it applies to methods, work, and projects. Covers statistics for cost analysis, general cost
analysis and bidding strategies for construction (i.e., bidding, estimate insurance, engineering economy, benefit
cost, and life cycle), and the newest models and techniques for cost estimating. "Practical Applications" encourage
field trips and communication through the internet, and a variety of interesting open-ended case studies actively
engage readers in realistic scenarios and help develop critical thinking skills. Integrates an extensive array
of exercises, qualitative questions, and problems, and limits math to algebra and introductory calculus.
For professionals in construction, civil and environmental engineering, and architecture.
