Article 5 Power to deviate
Subject to paragraph (3), in constructing or maintaining any of the scheduled works, the Agency may deviate—
laterally from the lines or situations shown on the works plans to any extent within the limits of deviation (if any) shown; and
vertically from the levels shown on the sections to any extent upwards or downwards.
Without limiting the scope of paragraph (1), in constructing or maintaining the scheduled works the Agency may, within the limits mentioned in paragraph (1)—
deviate from their points of commencement and termination as shown on the Order plans, and
deviate from the design shown on the Order plans.
The scheduled works must be constructed so that—
the unobstructed opening between the piers of the barrier, as shown on the Order plans, measures not less than 14 metres wide,
when not in operational use, the minimum height of the base of a vertical lift gate measures not less than 9 metres AoD, and
the minimum height of the base of the foot and cycle bridge measures not less than 9 metres AoD.
Nothing in article 4(3) (power to construct and maintain works) authorises the Agency to execute any works in contravention of the restrictions imposed by paragraph (3).
In paragraph (3), “AoD” means above ordinance datum.
