Commentary on provisions of the Act Schedule 1: Scheduled works Construction requirements
Schedule 1 sets out the Phase One scheduled works, which are the main works authorised by the Act. Each of these works has a centre line (or in the case of a road widening, a limit of widening) shown for it on the deposited plans, with a limit of lateral deviation, and a level shown for it on the deposited sections. By virtue of paragraph 1(1), the scheduled works must be constructed in the lines or situations, and at the levels, shown on these. Some stations, depots and shafts also have an upper limit shown for them on the deposited sections, in which case the relevant works must be constructed within the limit.
	Paragraph 1(2) allows deviation laterally from these lines or situations, but only within the limits of deviation shown on the plans. It also allows unlimited deviation downwards from the levels shown, and deviation upwards of not more than three metres. This power to deviate upwards is subject to any upper limit applying to stations, depots and shafts.
