Paragraph 107 I1

If at any time after the completion of a specified work or a protective work, not being a work vested in the Company, the Company gives notice to the undertaker informing it that the state of maintenance of any part of the specified work or protective work appears to be such as adversely affects the operation of HS1 property, the undertaker must, on receipt of such notice, take such steps as may be reasonably necessary to put that specified work or protective work in such state of maintenance as to not adversely affect HS1 property.
