3U.K.The nominated undertaker shall carry out all operations for the construction of any tidal works with all reasonable despatch to the reasonable satisfaction of the port authority (and shall promptly remove all temporary works as soon as the same are no longer required) so that river traffic shall not suffer more interference than is reasonably practicable and the port authority shall be entitled by its officer at all reasonable times, on giving such notice as may be reasonable in the circumstances, to inspect such operations.
