17A.— Where a court imposes a fine or affirms or varies a fine imposed by another court for an offence under this Act in proceedings brought by a building control authority, it shall, on application of the building control authority (made before the time of such imposition, affirmation or variation), provide by order for the payment of the amount of the fine to the building control authority and such payment may be enforced by the authority as if it were due to it on foot of a decree or order made by the court in civil proceedings.]
