Study Notes
Building Codes and Construction Types
- Subcategory (A) corresponds to protected materials, while (B) denotes unprotected materials.
- Type 1 construction (made of steel and concrete) offers the highest fire resistance; Type 5 (primarily wood) has the least.
- Fire resistance ratings are measured in hours, designated as 0, 1, 2, or 3 hours.
- All buildings are categorized under specific construction types.
- Type 4 construction is primarily for residential buildings.
- All structural elements must meet minimum resistance ratings for the building's classification.
Fire Resistance and Materials
- Non-combustible materials include steel, iron, concrete, and masonry.
- Type 1 and Type 2 buildings can incorporate limited combustible materials.
- Wood is a combustible material unless treated for fire resistance or categorized as heavy timber based on diameter.
Fire Safety Regulations
- Firewalls are necessary to subdivide a building with multiple construction types.
- Occupancy classifications such as assembly, hazardous, and institutional necessitate more evacuation time due to occupant abilities or numbers.
- A high-rise building is defined as exceeding 75 feet in height.
Construction Type Specifications
- Type 1 and Type 2 construction do not require rated interior walls and partitions.
- Type 5 is the least restrictive construction type with the most lenient fire ratings.
- Most combustible materials can be treated for enhanced fire resistance.
- Compliance with the latest building codes is crucial for all buildings.
Building Proximity and Regulations
- The distance to adjacent buildings can influence the permissible size of new constructions.
- Fire resistant construction materials are unaffected by flames, heat, or hot gases.
- Load-bearing walls, columns, and shaft enclosures are considered building elements under codes.
- Heavy timber refers to wood characterized by a large diameter that grants fire resistance.
Construction Type Misconceptions
- Incorrect statement: Combustible materials are prohibited in Type 1 but allowed in Type 2.
- Type 3 construction has non-combustible exterior walls but allows combustible interior elements.
- Unencased iron and steel rapidly lose strength if exposed to fire.
Separation and Occupancy Classifications
- Buildings with multiple construction types must used occupancy separation walls or firewalls for distinction.
- Strictest construction types are required for assembly and institutional occupancy classifications.
- To determine suitable occupancy classification for a building, know its construction type, square footage, and sprinkler status.
Size Limitations and Increases
- A building's maximum size is limited by construction types, occupancy classification, and proximity to other structures.
- Adding more occupancy separation walls can expand a building's allowable area.
- Internal renovations, such as adding openings in structural walls, do not affect construction type.
