Such amendment and rectification shall have the effect that:
(a) Project Co's Proposals shall satisfy the Board's Construction Requirements; and
(b) following the amendment or rectification, the structural, mechanical and electrical performance of the Facilities will be of an equivalent standard of performance to that set out in Project Co's Proposals prior to their amendment or rectification (for the purpose of this comparison disregarding the fault which required the amendment or rectification to be made).
