This book was motivated by the desire to further the evolution of a concise
book on Construction Practice, Planning & Management. Keeping in focus
the importance of this subject in GATE and ESE, we have done a proper study
and thereafter developed the content of the book accordingly. This edition has
an expanded discussion of all relevant topics in the subject.
Initially, we compiled the perceptions of our students on their problems in GATE
and ESE while dealing with the questions from this subject. We identified their
various problems like- lack of fundamentals of the subject, difficulty in solving
simple solutions, shortage of a complete study package, etc. These strengthened our determination to
present a complete edition of Construction Practice, Planning & Management textbook.
The book addresses all the requirements of the students, i.e. comprehensive coverage of theory, fundamental
concepts, objective type problems and conventional problems, articulated in a lucid language. The concise
presentation will help the readers grasp the concepts with clarity and apply them with ease to solve problems
quickly. The books not only covers the entire syllabus of GATE and ESE, but also addresses the need of many
other competitive examinations. Topics like ‘Project Management and Network Theory, PERT and CPM, Crashing of
Network, Resource allocation and CPM Updating, Construction Management, Engineering Economy Engineering
Equipments, Quality Control, Safety Management and Legislations’ are given full coverage in line with our research
on their importance in competitive examinations.
We have put in our sincere efforts to present elaborate solutions for various problems, different problem solving
methodology, some useful quick techniques to save time while attempting MCQs without compromising the accuracy
of answers. A summary of important points to remember is added at the end of each topic. For the convenience
of readers, points to remember are specifically highlighted in the form of a note- both in theory as well as solved
examples. At the end of each chapter, sets of practice question are given with their keys, that will allow the readers
to evaluate their understanding of the topics and sharpen their problem solving skills.
Our team has made their best efforts to remove all possible errors of any kind. Nonetheless, we would highly
appreciate and acknowledge if you find and share with us any printing, calculation and conceptual error.
It is impossible to thank all the individuals who helped us, but we would like to sincerely thank all the co-authors,
editors and reviewers for putting in their efforts to publish this book. We also express our thanks to MADE EASY
publications for completing and publishing the book on time.
With Best Wishes
