were not based on definitive criteria should not be included in the prep- aration of an estimate of cost of comparable domestic construction, Such an assumption would appear to be justified on the basis that communica- tions, timely procurement of materials and transportation of them to the Jobsite, and recruitment of labor present only relatively minor problems in a domestic construction job. On the basis of such an assumption, therefore, the net estimated cost of domestic construction of $13,442,523 should be reduced by ten per cent to eliminate contingency allowances, thus ylelding an estimated domestic cost of $12,098,271. Comparison of this latter figure with the total actual cost of construction at Eniwetok results in a multiplying factor of 2.043, On the basis of these computations, it will be seen that an average multiplying factor can be said to lie between 1.8 and 2.1. It should be remembered that such an average multiplying factor applies to the program of work performed and is not applicable to specific, specialized structures erec- ted at Eniwetok or to construction work involving the employment of extra- ordinary techniques, equipment or material, 12-28
