Paragraph 5 I1

Any operations for the construction of any tidal work approved in accordance with this Order, once commenced, must be carried out by the Harbour Authority without unnecessary delay and to the reasonable satisfaction of the Conservancy Authority so that river traffic, the flow or regime of the river and the exercise of the Conservancy Authority’s functions do not suffer more interference than is reasonably practicable, and an officer of the Conservancy Authority is entitled at all reasonable times, on giving such notice as may be reasonable in the circumstances, to inspect and survey such operations.
