Paragraph 6

At any time within a period of one month, or a period of 14 days in the case of trial holes or alterations, from the receipt by the Nominee of the plans referred to in paragraph 5 above the Nominee may by notice in writing to the undertaker specify any reasonable temporary or permanent works or measures (the “protective works”) which in its reasonable opinion should be carried out or taken by the undertaker before the commencement of or during the construction of the works in order to ensure the stability of the hydrant systems (shown where applicable on the drawings furnished by the Nominee under paragraph 4(2) above) or to protect them from injury (including injury by subsidence) and such protective works shall be constructed by the undertaker at its own expense and under the inspection (if any) of the Nominee.

Except in the case of protective works that the Nominee has informed the undertaker in writing may be carried out during the construction of the works, the undertaker shall not commence the construction of any work within fifteen metres of, or which may in any way affect, the hydrant systems until the protective works relating to that work have been completed to the reasonable satisfaction of the Nominee.

In the case of protective works of which the Nominee has informed the undertaker in writing as mentioned in sub-paragraph (2) above, the undertaker shall comply with all reasonable requirements of the Nominee arising from its inspection under sub-paragraph (1) above as promptly as practicable after the undertaker has been notified of such requirements.

Except in an emergency (when it shall give such notice as may be reasonably practicable) the undertaker shall give the Nominee not less than 14 days' notice of its intention to carry out any works for the repair or maintenance of the protective works in so far as such works may affect or interfere with the hydrant systems.
