It would be interesting if there was such a program. However, ADA
signs and wayfinding are very custom. The sizes have ranges, so not every
sign will be 5/8" text. Sometimes they want 2" and other times they want 1.5".
Then there is the consideration of are they including the clear mini
sign to allow more design freedom on the visible
sign. There are so many variables that even though a lot of items are repeatable, there are just as many (if not more) that are custom.
All we do are design and consulting for a large number of these types of projects and the secret sauce is experience (painful, painful experience, lol). It's also having a team with the ability to catch tiny details in projects with thousands of data points. Another factor to consider in these types of projects are local municipal code requirements. NYC wants 3" tall letters for their stair and elevator levels and naming, while NJ wants 2" tall letters & numbers for their stair and elevator levels and naming. While these are not part of ADA guidelines they are part of the IBC and NFPA guidelines. Then for fun you can also bring evacuation maps into the discussion. These have OSHA guidelines, that are not usually enforced, and local rules that may require them in these types of projects.
Lots of
sign companies are coming up with their own software and custom setups (we are too), and I still haven’t seen a turnkey solution that really works for projects like these.
