Excerpt from Estimating Sheet Metal Work: Tells in Plain English How to Figure the Proper Sizes of Articles, How to Take Off the Material Required From the Plans of Any Sheet Metal Job, How to Buy Material and Cut It to Advantage for Different WorkThe term Estimating in its general application means valuation of work or merchandise, based on no definite knowledge of cost. When the exact cost is known, the value can be stated instead of being Esti mated. Estimating, therefore, is employed before doing the work, while after the completion of the work, when values are known, the Cost is determined.It is generally necessary in conducting a business undertaking, to estimate or determine an approximate charge for work, when the exact values are not known. The estimator must therefore have an intense practical knowledge of the trade and should also be acquainted with the estimating methods which are employed, to determine the exact cost of business transactions, so as to be able to compile records of cost which give a posi tive basis for estimating of similar work to be per formed thereafter.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
