RISR1 This routine will calculate the different possible stair riser-count options given: - F2F in FIS (the finished floor to finished floor height)

Items calculated by this routine are: -

ADA Compliant riser details Typical Riser details Maximum Height Riser details Out of code Riser details

**NOTE: When plans are not clear, this is a good tool to use to quickly determine riser information for stair building.

As with all of these routines, the user is “prompted” to enter the required numbers so that the calculation can be performed.
