Estimating Labor Costs. In estimating labor costs the following data is to be made use of. The estimator will have to determine the hours per day and the scale of wages per hour paid in his locality, and make whatever changes in the data is necessary. He should also compare the quantity of work done by men he may observe with that given herewith. The time data herewith is based upon the work of one mechanic who has mastered his trade fairly well. With an efficient foreman and a selected group of workmen these time allowances can be reduced in many instances as much as one-half. Experience alone will determine the possibilities of such reductions with safety.
