Construction type (Type I, II, III, IV, V with subtypes A/B) describes the fire-resistance characteristics of the building’s structural elements (primary frame, bearing walls, floors, roof). More fire-resistive types generally allow greater height/area and provide more time for evacuation and firefighting. Type I is typically the most fire-resistive; Type V is typically combustible (e.g., wood framing).   Worked example(s) Example: A 5-story wood-framed apartment building over a concrete podium might be Type V-A above with Type I-A podium (a 'podium' configuration). The code has specific... Show more
