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 – 1.3.2.1 – 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 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 […]
