Paragraph 71 Co-operationI1

Where in consequence of the proposed construction of any part of the authorised development, the undertaker or NGET or NGT requires the removal of apparatus under paragraph 64(2) or NGET or NGT makes requirements for the protection or alteration of apparatus under paragraph 66 or 67, the undertaker must use its best endeavours to co-ordinate the execution of the works in the interests of safety and the efficient and economic execution of the authorised development and taking into account the need to ensure the safe and efficient operation of NGET or NGT’s undertaking and NGET and NGT must separately use their best endeavours to co-operate with the undertaker for that purpose.

For the avoidance of doubt whenever NGET or NGT’s consent, agreement or approval is required in relation to plans, documents or other information submitted by the undertaker or the taking of action by the undertaker, it must not be unreasonably withheld or delayed.
