National Lottery specifications - the latest I have ---- and I quote
'The current maximum gradient for an accessible ramp is 1 : 12. This means
that for every 120mm one moves forward the gradient would rise by 10mm.
This however is the absolute maximum.
Existing ramps that meet this criteria can be considered accessible, however
any new or refurbished ramps should aim to be at a gradient of between 1 :
15 and 1 : 20 with level resting places (150mm deep) every 5m. In areas
where the installation of a ramp is impossible due to the location of the
building a platform lift could be considerered as an alternative'
Lottery ask for the maximum and questions are :
Are all ramps leading to and within the venue at a gradient of 1 : 12 or
shallower?
Are all new ramps leading to and within the venue at a maximum gradient of 1
: 20?
Do all ramps have an unobstructed minimum surface width of 1200 mm?
Do all ramps have handrails at heights of 900 mm (1000mm at landings) and
600 mm on both sides running their entire length
Do handrails extend by 300 mm at the top and bottom of ramps to guide people
safely to level ground?
Do all ramps incorporate a level landing length at the top and bottom of
1200mm length, clear of door swings?
Do all ramps have firm non-slip surfaces?
Hope this helps and good luck in the new job - it is rather an up hill
struggle! Keep your sense of humour near the surface! Regards, Loretto.
