Types of Construction-Chapter 5 The IBC classifies all buildings into five broad types or categories of construction based on the fire resistance capabilities of the members used in their construction. 5 types given Roman Numeral classification – ranging from type I to Type V – most fire resistive to the least fire resistive Construction Types – Type I – Building elements are non-combustible – Type II – Building elements are non-combustible – Type III – mix of non-combustible elements(exterior walls) and combustible elements (interior) – Type IV – Heavy timber construction – Type V – Any material allowed, typically conventional light wood framed The five types of construction are subdivided into two additional categories – A and B, based on the inherent fire-resistance or combustibility of the materials Remember Table 503 - Height and area are predicated on the Occupancy group and the type of construction. Its our job to work with the three variables when making initial code analysis. The desired occupancy and size will determine the type of construction.
