Paragraph 9 I1

Nothing in paragraphs 5(5), 6(3), 7 and 8(3) and (4) authorises the Agency to execute works on or affecting the authorised development without the prior consent in writing of the undertaker.

Consent under sub-paragraph (1) must not be unreasonably withheld or delayed, and the undertaker is deemed to have given its consent if it has not refused consent within 2 months of receiving a written request from the Agency.
