Type I Construction vs Type IV Construction: A Building Code Perspective – A lot is known about Type I Construction (non-combustible) because it has been used for decades for multi-story construction. Although Type IV Construction (heavy timber) is not new, it is just now beginning to be used with greater frequency in multi-story construction. This presentation will provide an overview of the building code as it relates to Type I and Type IV Construction. Case studies will be used to demonstrate relevant code sections that apply to Type I and Type IV buildings using the current Minnesota Building Code including: Chapter 5 – Area and Height limitations of Type I and Type IV Chapter 6 – Fire Rating requirements for Type I and Type IV Chapter 7 – Fire and Smoke requirements, shafts, sound assemblies Chapter 9 – Fire and Life Safety requirements of Type I and Type IV Chapter 23 – Wood and heavy timber construction. In addition, materials and special inspections will be discussed for each type of building.
