If an order of mandamus, a mandatory order, an injunction or a judgment or order for the specific performance of a contract is not complied with, then, without prejudice to its powers under section 39 of the Act and its powers to punish the disobedient party for contempt, the Court may direct that the act required to be done may, so far as practicable, be done by the party by whom the order or judgment was obtained or some other person appointed by the Court, at the cost of the disobedient party, and upon the act being done the expenses incurred may be ascertained in such manner as the Court may direct and execution may issue against the disobedient party for the amount so ascertained and for costs.
