First of all, the total expenses due to constructing each part of the sys-tem, including dam, tunnel, power house and lines, are compared. Theneach expense is itemized and further compared to show the relative mag-nitudes of labor, material, transportation and miscellaneous items. Asmight be expected, these data show that labor is the largest item in con-structing each part of the plant. In building the dams the cost of cement,miscellaneous expenditures and cost of quarrying are next in magnitude,representing about 31 per cent, of the total expense. The expense of quar- 222. 10 15 20 25 30 Percentage of Total Construction Expense Fig. 123.—Relative Costs of Constructing Each Part of aHydroelectric Plant PLANT, LINE AND SUBSTATION COSTS 223 rying may be offset by the cost of sheet piHng in country where the soil issuch that water may seep under the dam. The plant, reinforcement andsupervision costs are about equal per cubic yard of concrete laid. .^*^Ve> l/ilfLLff
