(3) Upon signifying his approval or disapproval of the plans the engineer may specify any protective works, whether temporary or permanent, which in his opinion should be carried out before the commencement of the construction of the specified works to ensure the safety or stability of the canal, and such protective works as may be reasonably necessary for those purposes shall be constructed by the Executive with all reasonable dispatch:
(4) The Executive shall pay to the waterways board a capitalised sum representing the increased or additional cost of maintaining and, when necessary, renewing any permanent protective works provided under paragraph (3) above, but if the cost of maintaining the canal, or of works of renewal on the canal, is reduced in consequence of any such protective works, a capitalised sum representing such saving shall be set off against any sum payable by the Executive to the waterways board under this section:
