Fire stops
26
What’s is also known as heavy timber or Mill Construction
Type IV
27
What’s similarities does type IV have with Type III construction
Exterior walls are masonry and interior components are combustible
28
What are the distinctions between type III and Type IV construction?
Type IV beams/Columns/ floors/ roofs are solid or laminated with greater dimensions than Type III Concealed spaces no permitted in type IV
29
What subdivisions does type IV construction use instead of A and B ?

31
Heavy timber Construction (Type IV) construction requires what minimal nominal dimensions for lumber for floor construction?
Minimum nominal dimensions of 6 x 10 for floor construction
32
What’s the primary hazard of type IV construction?

What construction type allows all major structural components to be made of combustible material?
Type V wood frame
35
What fire resistance is Type V construction suppose for have for structural components in terms of hours?
1 hr fire resistance for structural components
36
How does type V construction add fire resistance to its construction?
Fire rated plaster or gypsum are used to protect combustible members
37
What’s the fundamental problem of Type V construction?
Concealed Void spaces
38
When does mixed construction occur
New structures are built onto existing structures of a different construction type
39
Building Construction and Occupancy classifications are used together in Building code to what?
