TGD M 2010 – 1.1.3.3 – Gently sloped access routes
1.1.3.3 Gently sloped access routes The following guidance applies to gently sloped access routes in addition to the general guidance in 1.1.3.1 above. For the purpose of this guidance, a gradient steeper than 1:50 (but less steep than 1:20) is considered to be gently sloped. Where a gently sloped access route is provided: (a) the […]
TGD M 2010 – 2.3.4.4 – Internal ramps
2.3.4.4 Internal ramps The guidance in 1.3.4.4 should be followed except: (a) where it is not practicable to provide the minimum clear width in 1.1.3.4, it should be as wide as possible, but the minimum unobstructed width between handrails should be not less than 1000 mm; (b) where it is not practicable to provide ramp […]
TGD H 2010 – 1.3.4.1 – Pipe gradients and sizes
1.3.4.1 Drains should be laid to falls and have enough capacity to carry the flow. The flow depends on the appliances connected (see paragraphs 1.1.2.2 to 1.1.2.5 and Table 1) and the capacity depends on the size and gradient of the pipes (see Diagram 7).

2.1.3.4 Ramped access routes The guidance in 1.1.3.4 should be followed except: (a) where it is not practicable to provide the minimum clear width (between walls, upstands or kerbs) in 1.1.3.4, it should be as wide as possible, but the minimum unobstructed width between handrails should be not less than 1000 mm; (b) where it […]

TGD H 2010 – 1.3.2.1 – Layout
1.3.2.1 The layout of the drainage system should be as simple as possible. Changes of direction and gradient should be minimised and as easy as practicable. Access points should be provided only if blockages could not be cleared without them. Connections of drains to other drains or to sewers should be made obliquely, and in […]
TGD J 2014 – 3.6.3.1 – Concealed flues
3.6.3.1 Where a metal or plastic chimney system is routed within a void and consists of more than 2 joints, appropriate means of access at strategic locations should be provided to allow a visual inspection to ensure the following: – the flue is continuous throughout its length, – all joints appear correctly assembled and appropriately […]
TGD H 2010 – 1.3.8.4 – Clearance of blockages, Siting of access points:
1.3.8.4 Siting of access points: Access should be provided at the following points: – (a) on or near the head of each drain run; (b) at a bend and at a change of gradient; (c) at a change of pipe size (but see below if it is at a junction); and (d) at a junction […]
TGD M 2010 – 1.1.3.4 – Ramped access routes
1.1.3.4 Ramped access routes The following guidance applies to ramped access routes in addition to the general guidance in 1.1.3.1 above. For the purpose of this guidance, a gradient of 1:20 or steeper is considered to be a ramp. Ramped access routes should be designed to have the shallowest gradient practical. The preferred maximum gradient […]
