Hi Steve,
It's really interesting to hear about treatments for existing buildings - something that hasn't really been covered in my architecture education - we're a bit obsessed by new builds I guess.
I was thinking if the surface is reflective and causes glare (which can be uncomfortable for people with a visual impairment) changing the type of light fitting or shading the daylight entering the space might help. The nosings seem to contrast really well with the stair so maybe you should advise that they take care to preserve the contrast when considering flooring treatments. Also, the importance of other indicators came up in our last discussion about tactile warning indoors and it looks just now like the handrail on the exterior wall doesn't extend 300mm horizontally beyond the top/bottom stair - this might be to stop it protruding into the circulation area although it looks in the 3rd photo like it could continue along the wall without protruding.
Hope my comments aren't too late!

Hi all
Interesting debate going on here.
I'm currently surveying a local train station that has an internal lift and staircase combined, with no tactile warning. The staircase is in a twisting formation with a hollowed out central core, with a tinted glass banister, metal handrail consisting of approximately 5 flights in all. The flooring is a smooth marbled almost polished affect tiling that is extremely slippy when wet.
Permanent 'slippery when wet' signs are everywhere and 'floor slippery' warning cones are strategically place every time it rains heavily.
Other than demolishing the entire structure, and based on others comments below regards pros and cons of internal stair tactiles, I'm wondering what the best advice might be in this situation/
Thanks Steve

Hi Vin
In the UK I agree, I was just informing this group what we are doing in Europe, I believe this is also the same in NZ, Australia & South Africa.
Which of us are behind the times them or us?? Just a question to start a debate not a criticism

That would be completely inappropriate - give an entirely wrong message and add an unnecessary hazard

Therefore, where possible, internal stairs should not be directly in line with an access route. Rationale: Due to the potential risk that people will not recognise the stairs in time".
