b'From the author:Thismanualwaswritten and configuredwith many different readers inmind.Thegoalwas to present thetechnical theories and equations in a simple, understandable way.This manual is not intended to be a rigorous texton soil mechanics and engineering theory.The intent was to produce a manual that distills the theory down tomake it easy to understand and to be able reach the answer, or arrive at a technical solution in a timely manner.Thetechnicalinformationprovidedhereincanhelptheengineerwithabasicunderstandingof soilsandfoundation support designs.Unlike some other technical manuals, there is nothing left out of this ECP Design andTechnical Service Manual that prevents the reader from performing a design analysis and arriving at a workablesolution without calling to a manufacturer or a professional engineer for assistance.This does not mean that oneshould not consult a registered engineer to clarify something or to review your analysis and solution.Engineers: The theoretical explanations, the assumptions, and equations to arrive at solution were written withengineers mind.It is the goal here to provide sufficient technical data and guidance necessary to design typicalfoundation support or tieback systems.This book is not intended to be a thorough analysis of all aspects of thesubject, but rather a handbook for determining solutions to typically encountered design situations in the field.The dry, technical theory is there if the reader is interested in learning the subject matter more thoroughly, but thereader can find extensive use of tables and graphs in this edition which were designed to reduce the need to masterthe engineering theory or the need to perform difficult mathematical equations to arrive at a solution.Non-Engineers: This book is also written with non-engineers in mind; such as project managers, estimators,contractors; and foundation repair company owners, office supervisors and field superintendents who are in thebusiness of installing foundation support systems.-SolveOur unique methods for rapidly obtaining estimates are presented throughout the book. Quick designestimating allows non-engineers to arrive at a viable solution to a foundation support problem in a minimumamount of time without a lot of mathematics. The reader will find that the Design Examples presented in thismanual are solved two ways.First, engineering theory and equations are used to design a support system, and-Solvesecondly bydemonstratinghow anon-engineercanuseour Quick design estimating toarriveata-Solvebudgetary solution. These side-by-side comparisons demonstrate that the Quick methods shown in thismanual produce comparable solutions.The product lines are divided into relevant chapters.While some topics overlap, an attempt to make each sectionstand alone so that the reader can concentrate on only the subject of interest at the time.1.
