after stating the case, delivered the opinion of the court.
The written contract between the parties in this case does not materially differ from the one before this court in
Martinsburg
&
Potomac Railroad Co.
v.
March,
*194 The only difference between that case and the present one is that the alleged mistakes of the engineer in the former were favorable to the railroad company, while in this case they are favorable to the contractors. But that difference cannot affect the interpretation of the contract. In the present case the agreement was that the work should be executed under the direction and supervision of the chipf engineer of the railroad company and his assistants, by whose measurements and calculations the quantities and amounts of the several kinds of work should be determined, and “ whose determination shall be conclusive upon the- parties.” Any decision of the chief engineer relating to the execution of the contract was to be “binding and final upo'n both parties.” His measurements and calculations as to excavations were made “ final and conclusive.”
• What are the substantial.facts found by the,'court below? The work was in four divisions, each division being in charge of an assistant or division .engineer, who acted under the general direction of the chief engineer. The agreement provided for monthly payments to the contractor, On the certificate of the engineer, “ for work done; ” ten per cent from the value thereof to be retained by the company until the whole work was completed in accordance with the contract. • The work was under the immediate supervision of the division engineer. On the first day of each month he made up and forwarded to the assistant chief .engineer an estimate of work done on each section of his division, according to quantities and classifications. Upon such estimates the assistant chief engineer ascertained the amount due the contractor to the beginning of the month. These monthly estimates were approved by both the assistant chief engineer and chief engineer. This course was ■pursued until the work was substantially completed, and was accepted and taken possession of by the company. Subsequently, without the knowledge or cooperation of the contractors, Baker, a-subordinate engineer of the railroad company, who had not supervised the work of the plaintiffs, reestimated and reclassified it, and upon such reestimate and reclassification, which were approved by the chief engineer, *195 the company claimed that the monthly estimates upon which the plaintiffs had been paid from time to time were much too large.
We are of opinion that the ultimate facts, as' found by the court, do not authorize the railroad company to go behind the estimates from time to time by its division engineer, which were approved and certified by the assistant chief engineer and chief engineer. Within a reasonable interpretation of the contract, the last monthly estimate of work done on division nine, (that being the only division here :in dispute,) followed by the acceptance by the company of the whole work, was a certificate of complete performance entitling the plaintiff to be paid in full according to the terms of the contract. While there was evidence tending to show that the estimates by the division engineer, upon which the last monthly certificate was based, were not made up from actual measurements on the ground, but from reports by subcontractors, there was, also, evidence tending to show that the remeasurements and reclassifications which the company caused to be made after the completion and acceptance of the work, and which it calls the “ final estimate,” were inaccurate. But there is no fact distinctly found indicating fraud upon the part of the company’s engineers, or such gross mistakes by them as imply bad faith. It is found only that the monthly estimates might, with reasonable care, have been made nearly accurate, and that, if the ^measurements and reclassifications were correct, the discrepancy between them and the monthly estimates, upon which the plaintiffs were paid from time to time, could be explained only upon the ground of negligence, ’incompetency or dishonesty' upon the part of the division engineer. But the court did not find that the monthly estimates were inaccurate, or that the chief or division engineer was dishonest, or that the subsequent remeasurement and reclassification were •correct. The mere incompetency or mere negligence of the division or chief engineer does not meet the requirements of the case, unless their mistakes were so gross as to imply bad faith.
We are of opinion that the judgment is supported by the finding of facts, and' it is Affirmed.
