53.—(1) Subject to sub-paragraph (2), nothing in this Order authorises the undertaker to—
(a)construct or maintain any specified work or protective work which would have the effect of exceeding the load bearing capacity of any part of the existing river wall which is not replaced by the specified work or protective work; or
(b)use any part of the river wall which is not to be replaced by the works as a load bearing wall or structure for any specified work or protective work.
(2) The provisions of sub-paragraph (1) do not apply where the GYPA has accepted the findings of a risk assessment carried out by the undertaker, including supporting calculations, that demonstrates that the load bearing capacity of the relevant part of the river wall would be adequate with or without specified reinforcement.
(3) The GYPA must not unreasonably withhold its acceptance of a risk assessment under sub-paragraph (2), must give its decision within 10 working days of the undertaker submitting its risk assessment, but may give its acceptance on terms that the undertaker must carry out any specified reinforcements.
