Article 6 Power to deviate
In constructing or maintaining the scheduled works, DLRL may—
deviate laterally from the lines or situations shown on the deposited plans within the limits of deviation relating to that work shown on those plans; and
deviate vertically from the levels shown on the deposited sections to any extent not exceeding 0.5 metres upwards or downwards.
Without prejudice to the generality of paragraph (1), in constructing or maintaining the scheduled works DLRL may, to the extent that it thinks fit—
deviate from their points of commencement and termination shown on the deposited plans; and
in relation to any intended viaduct, gantry or other structure or apparatus above ground level, deviate from the design shown on the deposited sections as it thinks fit, including by varying the number of any supporting piers, columns or other structures, the distances between them and the height or clearance above the level of the ground.
