The Department may determine losses sustained by contractors engaged on State highway projects incident to the suspension of work on such project by a court injunction order and may compensate such contractors for the amounts of the losses so determined. But this authority shall be limited to the payment of actual and unavoidable losses, not to include anticipated profits. Should any contractor be dissatisfied with the determination of his losses by the Department, such contractor may bring suit against the Department in the court of common pleas for the determination of the reasonableness of the amount of the award for such losses.
