Certain fixed costs, including depreciation and sometimes interest charges, are omitted if they do not represent a cash payment. Bank excavation, intermittent ripping, basement digging of natural bed clays, sands, silts, gravels. The objective in developing a machine rate should be to arrive at a figure that, as nearly as possible, represents the cost of the work done under the operating conditions encountered and the accounting system in use. If fuel consumption records are not available, the following formula can be used to estimate liters of fuel used per machine hour. Long and short hauls.
