- Type III (ordinary)—age of the building
- Type IV (heavy timber)—fire cuts
- Type V (wood frame/lightweight)—balloon or platform construction, including fire stopping

Process/Skill Questions:

- What types of building construction are found in the local area?
- What are the potential hazards with the five types of construction, and how do they affect firefighting efforts?
- What are the hazards associated with lightweight truss roofs?
