ROBERTS, Justice.
This case involves the meaning and application of the terms of a standard form of Government construction contract.
The findings of the Court of Claims may be summarized. In 1931 the War Department asked bids for the construction of a levee on the east side of the Mississippi River. The respondent bid 14.43¢ a cubic yard on a section of the work involving approximately 3,881,600 cubic yards of earthwork. A paragraph of the specifications reserved the right to make such changes in the work contemplated as might be necessary or expedient to carry out the intent of the contract or to meet unanticipated conditions, but added that no such modification would be the basis for a claim for extra compensation except as provided in the regular form of contract to be entered into between the parties.
The respondent began construction at the south end of the project and proceeded northward. The length of the proposed levee was divided by stations one hundred feet apart and numbered from north to south. Sixty-eight per cent. of the construction between Station 5123 and Station 5113 had been completed when portions of the levee already constructed south of Station 5123 were found to have a tendency to subside. For this reason the Government contracting officer, on October 7, 1932, ordered the work stopped between the two stations while he sought to determine the cause of the subsidence. He concluded that the placing of an enlarged false berm, not called for in the original specifications, would prevent subsidence in the sector between the two stations. On October 18th he gave respondent a written order to construct such a berm; the order stated that respondent would be given one hundred per cent. credit for the earth placed south of Station 5123 where the subsidence had occurred and that payment for additional yardage required by the false berm would be made at the contract price per cubic yard. The additional yardage involved was about 64,000 cubic yards. The work covered by the change order was necessary for the completion of the project. The order was issued against the respondent's protest that an extra price should be allowed as the additional work would cost the respondent more than 14.43¢ per cubic yard, and that the order was not within the terms of the contract. The respondent asserted it would later present a claim for extra cost occasioned it by the additional work.
Article 3 of the standard form of construction contract signed by the parties provides: 'Article 3. Changes.-The contracting officer may at any time, by a written order, and without notice to the sureties, make changes in the drawings and (or) specifications of this contract and within the general scope thereof. If such changes cause an increase or decrease in the amount due under this contract, or in the time required for its performance, an equitable adjustment shall be made and the contract shall be modified in writing accordingly. * * * Any claim for adjustment under this article must be asserted within ten days from the date the change is ordered, unless the contracting officer shall for proper cause extend such time, and if the parties can not agree upon the adjustment the dispute shall be determined as provided in Article 15 hereof. But nothing provided in this article shall excuse the contractor from proceeding with the prosecution of the work so changed.'
'Article 15. Disputes. Except as otherwise specifically provided in this contract, all disputes concerning questions of fact arising under this contract shall be decided by the contracting officer or his duly authorized representative, subject to written appeal by the contractor within thirty days to the head of the department concerned, whose decision shall be final and conclusive upon the parties thereto as to such questions of fact. In the meantime the contractor shall diligently proceed with the work as directed.'
The respondent did not appeal from the order of the contracting officer to the head of the department concerned. After completion of the work, the acceptance of the Government's final payment was under protest. Thereafter respondent brought this action for its additional costs over the price of 14.43¢ paid it for the extra work and was awarded a recovery by the court below.
