24. Whenever the Engineer shall be of opinion that any delay in the execution of any act or work specified in section 7 would be attended with grave danger to life or property, he may forthwith execute or cause to be executed such act or work: Provided that he shall without delay prepare or cause to be prepared the estimates, specifications and plans of such act or work together with a copy of the map as provided in section 7, and shall cause general notice to be given that the act or work mentioned therein has already been commenced; and thereupon such proceedings and inquiries shall be had as in and by Part II of this Act are directed.

25. Whenever it may have been determined in the final order to be passed on any such enquiry that anything done by the Engineer under the last preceding section was unnecessary, any person who shall have sustained damage by the execution of such works shall receive compensation from the Government or the Authority to be assessed according to the provisions contained in Part IV of this Act; and, on receipt of any application to that effect by the Engineer from any person so affected, the land or the embankments or drainage shall, so far as any alteration thereof shall appear to have been unnecessary, be, at the expense of the Government or the Authority, restored as nearly as possible to the state in which they were when the Engineer commenced to act under the provisions of this Part.

26. If any portion of the land likely to be affected by any work to be undertaken under this Part lies within another Division under the Water Wing of the Authority, the Engineer who causes the work to be executed shall, when commencing upon it, give notice of the same to the Engineer of such other Division under the Water Wing of the Authority; and the provisions of section 17 shall be applicable to all proceedings connected with the work and the cost thereof.
