The plaintiff company engaged by written contract to construct for the borough of Dubois, as part of a projected municipal water supply system, a section of the work designated in the plan as Anderson Creek dam or reservoir, in accordance with certain specifications, for the sum of $24,482.30. This price was based on estimates furnished by the borough as to the probable amount of work and material that would be required. Had there been no departure from the original plans and specifications, these estimates would have proved sufficiently accurate, and no controversy would have arisen. It rarely happens, however, that constructive work of this character is completed in exact accordance with the original specifications, for the reason that actual conditions below surface can only be known as the work is proceeded with, and disappointment with respect to these necessarily involves change in some degree. This contract contemplated such contingency, and, as we shall see, provided against it, both with respect to the rights of the borough, and the compensation to be paid the contractor. In the specifications furnished prospective bidders the work was classified according to the kind and character, as, for instance, grubbing, excavating, masonry, puddling, etc, each being made a distinct item, and with each item was given the approximate amount required under the estimates. The plaintiffs' bid specified in detail the rate price at which it would furnish the labor and mate
The contract provided that the plaintiff was to be paid in monthly payments based on estimates by the engineer of the value of the work done. These estimates were regularly made as the work was proceeded with, and the plaintiff was paid each in full, excepting the last for $1,995.15, which the defendant withheld under a claim of right to be considered. There is no finding by the court that questions in any way the accuracy of these estimates either with regard to the amount of work actually done or its value, if measured' by the scale of prices which was to govern for classified work. The amount in controversy is therefore reduced under our ruling to this sum. It was stipulated in the contract that the work was to be completed within five months from June 6, 1901, and that for each day it remained unfinished after the limit $15.00 should be deducted from the plaintiff’s compensation, as ascertained and liquidated damages for engineering and inspecting expenses. By agreement the time was extended for another five months; but the work was not completed for more than a year and a half after the expiration of the extension. For this breach of the agreement the defendant claims as damages what remained unpaid on the contract price. The findings of the court on this branch of the case are most meager and unsatisfactory. One is that the increase of the work made it impracticable, considering the difficulty attending it, for the plaintiff to complete it within the specified dates; another is that if it were extended in proportion to the cost of the increase no more time was taken by the plaintiff than it
