Paragraph 61 I1

If at any time after the completion of a specified work BPC gives notice to the undertaker informing it that the state of maintenance of any part of the specified work appears to be such as adversely affects the operation or use of any of BPC’s property (including the Port’s railway) in connection with carrying on BPC’s statutory undertaking, the undertaker must, on receipt of such notice, take such steps as may be reasonably necessary to put that specified work in such state of maintenance as not to adversely affect the operation or use of such property in that connection.
