23
Q

A

The minimum width for this component of a space plan is 44” (118mm), but a recommended width is 60” (1500mm)

24
Q

2. Palm Wood

25
Q

What does the Certificate of Occupancy (or Use and Occupancy) letter provide?

A

This letter is issued by the authority having jurisdiction and allows the client to occupy a building or portion of a building after the final inspection.

26
Q

What is the primary model building code used in the US?

A

IBC - The International Building Code is the primary code for this

27
Q

In the United States, what documents gives jurisdictions the basic authority to adopt and enforce building codes?

A

This basic authority for this comes from The Tenth Amendment to the U.S. Constitution. It gives police power to the states, which in turn either use that authority to adopt codes or pass that authority on to local jurisdictions.

28
Q

What two types of product labels does Underwriters Laboratories (UL) provide?

A
  1. Listed Labels

2. Classified Labels

29
Q

What is the Steiner tunnel test, ASTM E84?

A

This is a standard test for determining the surface burning characteristics of fifth materials and the smoke developed index of the same materials.

30
Q

According to the International Building Code (IBC), what is a fire partition, and where is it used?

A

The IBC define as a wall assembly having a fire-resistance rating of one hour, used in

  1. walls separating dwelling units
  2. walls separating guest rooms in group R-1, R-2, and I-I occupancies
  3. walls separating tenant spaces in covered malls
  4. Corridor walls
31
Q

What two situations require the constructions of a fire barrier?

A

This type of fire-resistance-rated wall is required as

  1. a separation where there are different occupancies
  2. an enclosure where there are vertical exits
32
Q

What is the maximum percentage of wall or ceiling area that combustible trim (such as trim made of wood) can occupy in a room?

A

In a room, this material type can occupy no more than 10% of a wall or ceiling area.

33
Q

What is an accessory occupancy?

A

This is a space or room that is used in conjunction with the main occupancy, but containing no more than 10% of the floor area of the main occupancy.

34
Q

What is an incidental use area?

A

This is a area that is ancillary to the main occupancy, but has the same classification. It must be separated from the main occupancy by a fire barrier, be equipped with an automatic sprinkler system, or both.

35
Q

What is fire-resistance-rated glazing?

A

This is glass or some other glazing material that has been tested according to ASTM E119 as part of a fore-resistance-rated wall assembly.

36
Q

In regard to interior design, what is a guard, and what dimension must it have in commercial construction?

A

This is a building components installed to prevent falls from an elevated area. Its required minimum height is 42” (1067m) above the floor.

37
Q

What are the three parts of a meas of egress?

A

Its three parts are

  1. Exit access
  2. Exit
  3. Exit distance
38
Q

What is an exit passageway?

A

This is a horizontal, fully enclosed, fire-resistance-rated portion of an exit that is used only as a means of egress to an exit distance or a public way.

39
Q

What is an occupant load factor?

A

This is the amount of floor space that a building code presumes is occupied by one person in a particular occupancy.

40
Q

How is the occupant load of a space calculated?

A

To calculate this value for a space, the total area in square feet (or square meters) is divided by the occupant load factor.

41
Q

What is a common path of egress travel?

A

This is the portion of an exit access that occupants are required to traverse before two separate and distant paths of egress travel to two exits become available.

42
Q

What are the two main factors in determining if a space requires two exits rather than just one?

A

The tow main factors that determine how many of there are required are the space’s occupancy and its occupant load.

43
Q

In a building that has been fully equipped with sprinklers, when two exits are required in a space, what is the minimum separation required?

A

The minimum separation required is one-third the diagonal distance of the space

44
Q

What is an exit access travel distance?

A

This is the distance an occupant must travel from the most remote point within a building to the entrance of the nearest exit.

45
Q

How is minimum exit width calculated?

A

This is calculated by multiplying the occupant load of a space by the appropriate factor given in the building code.

46
Q

For an occupant load greater than 50, what is the absolute minimum corridor width?

A

In this instance, the minimum corridor width is 44” (1118mm)

A

Within a meas of egress system, these are area that do not provide a protected path of travel and which lead to the entrance of an exit.
In the international Building Code (IBC), even fire-rated corridors are included in this category.

48
Q

A

The minimum clear width is 32” (813mm)

A

The maximum height of the former is 7” (178mm), and the minimum depth of the latter is 11” (279mm)

51
Q

Two materials that can be used for this application are tempered glass and laminated glass, but only if they pass the testing requirements of 16 CFR 1201 (Code of federal Regulations), category II.

52
Q

In regard to building codes, what are reference standards?

A

These are standards written by standards-writing organizations (rather than by the authors of a particular building code) that are made part of a code by specific reference.
