Request for Relief From Losses Suffered in Performance of Contract

The contractor requested relief for losses which allegedly were incurred in the performance of a fixed-price contract due to the need to use a foundry and pattern maker other than those originally intended. There was no basis for an equitable price adjustment of the contract, which contained no escalation provisions, since the factors causing the increased costs did not constitute undue interference by the Government as a contractor. The contractor's request for an increase in contract price based on an erroneous estimation of its costs was denied since the mistake was unilateral, and there was no basis to conclude that the contracting officer was on constructive notice of a possible error.
