Heavy Timber (Type IV) buildings can be defined as those that have block or brick exterior load bearing walls and interior structural elements of a substantial dimension (greater than 8 inches/20 cm) in thickness and width. Type IV buildings are like Type III but larger dimension lumber is used and void spaces are minimized. (Incident Safety Officer, p. 65)

Industrial Era (Incident Safety Officer, p. 68)
List the 5 steps to predicting building collapse.
Divide the 5 steps into three “processes”
Step 1: Classify the building’s construction using the “type/era/use/size” approach
Step 2: Determine structural involvement (read the smoke and flames)
Step 3: Visualize and trace loads
Step 4: Evaluate Time
Step 5: Predict and communicate collapse potential (foundation for zoning).
Step 1 and 2 are the “identification process”
Step 3 and 4 are the “Analytical process”
Step 5 is the “decide and communication process”
