Interior Signage & Wayfinding
CSI Division 10, Specialties
Room numbers, directional signs, and ADA-compliant tactile and Braille signage installed throughout a finished building to help occupants and visitors navigate it, coordinated against the project's actual room numbering and code-required accessible signage locations rather than added as an afterthought once finishes are complete.
Why it matters
ADA sets specific requirements for tactile signage mounting height and location at each door, and getting that wrong after fabrication means re-fabricating and reinstalling every affected sign in the building rather than making one easy fix.
On a real project
An office building's signage package is finalized only after room numbers are confirmed against the as-built floor plan, with ADA-compliant tactile signs mounted at the latch side of each door at the code-required height.
Who this matters most to
A Facilities Manager often reviews the signage plan before fabrication, since these signs stay in service for years. A Carpenter or specialty installer mounts them once fabricated.
Where this goes wrong
A signage package is fabricated from an early floor plan before a late room-renumbering change takes effect. The installer mounts an entire building's worth of signs bearing the wrong room numbers, and the whole package has to be refabricated and reinstalled.
