ing on the different cards the prevailing prices, or last purchase prices, the sources of supplies, reference to catalogues and any other information of importance for estimating.

Preparing the Estimate

In the chapters immediately following here, the reader will find the manner of taking off material from plans,

and in conclusion of each chapter a summarized form of estimate for the work treated in each chapter. There are many different forms used for the simimarizing of estimates; each having its advantages and disadvantages. This is, however, mostly a matter of personal convenience to the estimator. The principal idea with all forms used is to present the estimate in such shape that the items are clearly set forth, so that the figures can be readily checked off as to their correctness and allow easy reference to them at any future date. The writer prefers a sheet which has a margin at the left, which is used for arithmetic work, so that the broad space at the right is used only for itemizing cost items and computed figures*

Splendid estimate forms have been compiled, especially for heating work, and we refer the reader to other publications on estimating, in which niunerous scheduled estimate blanks adaptable for the sheet metal worker are reprinted.*

How ever valuable any information may be that the reader is able to gather from this book and other works on "Estimating," an essential requirement for estimating work is a thorough knowledge of elementary arithmetic and accuracy in figuring, which can be acquired only by diligent practice. Estimates should never be considered correct before same have been checked in all items, preferably by someone else than the person who prepared the estimate.

Uniform estimate sheets (not necessarily printed) should be used, and all basic information regarding the job should be set forth on the sheet, so that the estimate can be easily checked. The estimate is a fundamental part of successful business, and should be treated with all due regard of its importance.
