TGD M 2010 – 3.1.2.4 – Ramped access route

3.1.2.4 Ramped access route Where a ramped access route is necessary due to site constraints it should be designed to have the shallowest gradient practicable. For the purpose of this guidance document a gradient of 1:20 or steeper (but not exceeding 1:12) is considered to be a ramp. In addition to the general guidance given in 3.1.2.1 where a ramped access route is provided: (a) level landings should be provided between ramp flights or wherever a change in direction occurs. A level landing is considered to include gradients of 1:50 or less steep; (b) the length of all landings should be not less than 1200 mm exclusive of the swing of any door or gate, which opens onto it; (c) where the gradient is between 1:20 and not exceeding 1:15 the length between level landings should be a maximum 10 m; (d) where the gradient is between 1:15 and 1:12 the length between level landings should be maximum 5 m.
