Mixed Combustible / Noncombustible Construction Type IV-HT (Sprinklered): Mass Timber
A shaft is defined by the IBC as “any enclosed space extending through one or more stories of a building, connecting vertical openings in successive floors, or floors and roofs.”
This applies to stairs, elevators, and mechanical/electrical/plumbing (MEP) chases in multi-story buildings.

*first two floors (below grade) are concrete construction (Type IA); timber construction begins on Ground Level
**if building is single story, maximum area for that story is allowed to be 102,000 SF; our building is multi-story, therefore each floor can’t exceed 76,500 SF
