CD's Building Codes & Regulations Flashcards
when and who published Englands first building code?
1189 by Henry Fitz-Elyne Assize. Latter in 1666 after the great fire the Act of Parliament set forth requirements for the rebuilding of the city. This law set up different classes of buildings and described permissible materials.
what is the Metropolitan Building act of 1844?
an evolution of the 1666 building code where now they regulated heights, occupancies and building types.
when and where was the 1st recorded code in America?
1625 in NYC. it regulated the types of roof coverings to protect buildings from chimney sparks.
what is BOCA?
Building Officials Conference of America. created in 1915
what is the Uniform Building Code?
started in 1927
the standard building code?
started in 1945, published by the southern building code congress.
what are the three codes that merged to form the IBC?
BOCA, UBC, & Standard Building Code
what is NFPA?
National Fire Protection Association, first publication was in 2002.
whats the one companion code the ICC doesnt publish?
the NEC or National Electrical Code
what is the ANSI code that covers accessible design?
ANSI 117.1-1998
what are these standard writing organizations stand for? ASHRAE IES GA ACI AISI AITC
ASHRAE: American Society of Heating, Refrigeration and Air Conditioning Engineers.
IES: Illuminating Engineering Society
GA: Gypsum Association
ACI: American Concrete Institute
AISI: American Iron & steel Institute
AITC: American Institute of Timber Construction
what is the NFPA 5000?
its an alternative building code to the IBC
what does ANSI do?
it doesnt publish or develop standards, instead it approves standards developed by other organizations. It ensures industry consensus & avoids duplication.
what is NRTL?
National Recognized Testing Laboratory. Its an independant lab recognized by OSHA to test products & specifications
what is ASTM E-119?
its the Standards Methods of Fire Tests of Building Construction. This test involves building a sample wall and testing how it resists a fire. Its goal is to determine the temp at which the surface or adjacent materials on the side of the assembly will combust,
what is ASTM 252?
Fire tests of Door assembly. evaluates the ability of a door to resist the passage of flames & heat.
What is NFPA 257?
Standard on Fire for Window Assemblies.
What is ASTM E-84
Standard test method for surface burning characteristics of building materials. AKA Steiner Tunnel Test and it rates the surface buring characteristics of interior finishes.
flame test ratings Class: A B C
A: 0-25 most resistant
B: 26-75
C: 76-200 least resistant
ASTM E-119 is what?
the hourly rating for construction assemblies.
what is a fire partition?
its a wall with a 1hr fire resistance rating. They must be securely attached and extend continuously though concealed spaces.
used in the following ways:
- Wall separating dwelling units
- walls separating guestrooms in R-1 groups
- Wall Separating tenant spaces
- corridor walls
what is a fire barrier?
its a vertical or horizontal assembly that is designated to restrict the spread of fire or to allow safe egress. They must always be continuous to underside of deck. They may be req’d to have ratings over 1hr versus the partition that is only 1hr
used in the following ways:
- To enclose vertical exit enclosures (stairways), exit passages & incidental use areas.
- To separate different occupancies in a mixed occupancy bldg.
- to otherwise provide a fire barrier where specifically req’d by a code provision of the IBC
with a fire barrier how are openings restricted?
25% of the aggregate width of a wall and any single opening can’t exceed 120’ (unless bldg has sprinklers)
what is a fire wall?
it is a fire resistance rated wall that is used to separate a single structure into separate construction types or provide allowable area increases buy assembly what amounts to separate but attached buildings. they must extend from foundation threw the roof.
what is a smoke barrier?
its a continuous verticle or horizontal membrane w/ a minimum fire resistance rating of 1hr thats designated & constructed to restrict the movement of smoke. openings in this barrier must be 20m rated.
curtains and draperies need to conform to what flame resistant standards?
Groups A, E, I or R-1 & dorms in R-2. and pass NFPA 701.
what are the administration requirements of the bldg code?
its the procedures for building officials to follow.
what are the 10 different occupancy groups?
A - Assembly B - Business E - Educational F - Factory/ Industrial H - Hazardous I - Institutional M - Mercantile R - Residential S - Storage U - Utility
knowing the building occupancy is needed to determine what?
max area, the number of floors allowed & how the building may need to be separated, occupancy calc, egress design, interior finish requirements, fire detection/ suppression. Ventilation and sanitation req’mts.
how can you handle mixed occupancy bldgs?
Separate occupancy groups with a fire barrier. or permit under the most restrictive use.
what is an accessory area?
its a secondary use area that is used in conjunction to the main occupancy and does not exceed 10% of the floor area of the main use. These accessory do not need be separated from the main occupancy w/ a fire barrier.
what is an incidental area?
its an area that is incidental to the major occupancy & classified the same as a major occupancy portion of the bldg. These must be separated by a fire barrier per table 302.1.1 of the IBC.
Type I Type II Type III Type IV Type V
Type I: Non combustible Type II: Non combustible Type III:Combustible Type IV: Combustible Type V: Combustible
Describe the difference with the 5 construction types?
TYPE I-A–Fire Resistive Non-combustible (Commonly found in high-rise buildings and Group I occupancies).
TYPE I-B–Fire Resistive Non-Combustible (Commonly found in mid-rise office & Group R buildings).
TYPE II-A–Protected Non-Combustible (Commonly found in newer school buildings).
TYPE II-B–Unprotected Non-Combustible (Most common type of non-combustible construction used in commercial buildings).
Building constructed of non-combustible materials but these materials have no fire resistance.
TYPE III-A–Protected Combustible (Also known as “ordinary” construction with brick or block walls and a wooden roof or floor assembly which is 1 hour fire protected).
TYPE III-B–Unprotected Combustible (Also known as “ordinary” construction; has brick or block walls with a
wooden roof or floor assembly which is not protected against fire. These buildings are frequently found in
“warehouse” districts of older cities.)
TYPE IV–Heavy Timber
TYPE V-A–Protected Wood Frame (Commonly used in the construction of newer apartment buildings; there is no exposed wood visible.)
1 Hr. Exterior Walls
1 Hr. Structural Frame
1 Hr. Floor/Ceiling/Roof
TYPE V-B–Unprotected Wood Frame (Examples of Type V-N construction are single family homes and
garages. They often have exposed wood so there is no fire resistance.)
