In this appeal we are asked to review the trial court's determination of the amount of increased compensation which a plumbing contractor was entitled to receive after the School District of the City of Philadelphia had temporarily advanced the date for completing a school construction

project. The trial court's award of additional compensation was determined by the difference between the contractor's actual labor costs and the amount of the estimated labor costs included in his original bid, plus 15 percent for profit and overhead. In addition, the court made an award representing a ten percent saving which the contractor might have been able to make on the estimated labor costs contained in his original bid.

upon by the Board and the contractor. If, however, unit prices are not applicable, and if the parties cannot agree upon a lump sum then additional compensation to be paid the contractor shall be determined by the actual net cost in labor and materials plus fifteen per centum (15%) for profit and overhead . . . .
