I work for a University who is renovating a small area of the basement(15,000 square feet) in an existing 5 story library. They will be adding classrooms to the space. The build was constructed in the early 80's and retrofitted with a sprinkler system after Katrina 2005. The basement area has 3 means of egress as well as an area of refuge with two way communication. Do we have to add a special lift in order to meet ADA requirements from the basement? I thought the area of refuge would be sufficient.
