It is always good to do site visits with clients, and even the architect joined us today. The architect was quite young and intelligent, and didn't fall into the usual mindset of thinking that, as an architect, he knew all about access and the issues involved.
However, both client and architect were falling into the usual trap of only considering wheelchair access (whilst not even thinking about emergency egress). I realise that I must use the statistic with caution, but it can be useful to point out to people, like this, that only 4% of People with Disabilities (PWD) actually own a wheelchair, and of that % only half of us need to are a wheelchair all the time. Sure, wheelchair access is often the most difficult and expensive to "fix" but all too often people forget to design to include other impairments.
