1

Fire extinguishers must be no more than how many feet/meters from the furthest occupant?

Fire extinguishers MUST be located no more than 75' (23 m) from the furthest occupant

2

In an accessible shower, on how many sides of the stall are grab bars required?

ALL accessible showers MUST have horizontal grab bars on three (3) sides mounted at a height between 33" (840 mm) and 36" (900 mm) AFF.

3

A thermostat can be mounted:

1. on a corridor wall providing there is adequate clear space

2. on a mullion

3. on or near glazing

4. at 60" AFF for accessibility

1. On a corridor wall providing there is adequate clear space

A thermostat should not be mounted on or near glazing, exterior walls or heat sources so that it registers temperature correctly. Standard mounting height is 48"AFF.

What is minimum clear width of the doorway and maximum size of an egress door?

32" & 48"

Source: 2015 International Building Code
1010.1.1 Size of doors.
The required capacity of each door opening shall be sufficient for the occupant load thereof and shall provide a minimum clear width of 32 inches (813 mm). Clear openings of doorways with swinging doors shall be measured between the face of the door and the stop, with the door open 90 degrees (1.57 rad). Where this section requires a minimum clear width of 32 inches (813 mm) and a door opening includes two door leaves without a mullion, one leaf shall provide a clear opening width of 32 inches (813 mm). The maximum width of a swinging door leaf shall be 48 inches (1219 mm) nominal. Means of egress doors in a Group I-2 occupancy used for the movement of beds shall provide a clear width not less than 411/2 inches (1054 mm). The height of door openings shall be not less than 80 inches (2032 mm).

See codes for exceptions

Which of the following requires flexible ducting that is connect to main ductwork:

1. supply air register

2. return air grill

3. sprinkler branch line

4. air handling unit

1. Supply air register

Supply air registers are often connected to the main ductwork with flexible ducting. This allows some adjustability in the exact location of an air register if its location conflicts with some other ceiling mounted item. The mechanical engineer should be consulted to determine how much the registers can be moved. On the Practicum - refer to your program instructions.

6

Which switching symbol indicates that a light can be controlled from two different areas or two different switches?

1. $2OS

2. $2

3. $DSS

4. $3

4. $3

$3 is the symbol for a 3-way switch, which means it is controlled from 2 (two) locations - NOT 3 (it has 3 terminals inside the switch).

7

Which type of lights can be switched together?

1. LED and fluorescent

2. none of these can be switched together

3. LED and halogen

4. LED and MR16

2. None of these can be switched together

Incandescent lights should generally be on a circuit separate from fluorescent lights. Incandescent lights are often on 120 V circuits and fluorescent lights are connected to 227V circuits. Lights on a dimmer should be on a separate switch.

On the Practicum, the program guide provides specific instructions for how lighting should be switched and typically requires the candidate to switch each type of light separately.

8

As the interior designer for a new tenant space in a non sprinklered building, you are determining the location of the two suite exits. If the diagonal distance between the two furthest points in the suite is 78 feet (24 m) what is the minimum distance needed between exits?

1. 39 feet (12 m)

2. 30 feet (9 m)

3. 26 feet (7.8 m)

4. 50 feet (15.3 m)

1. 39 feet

In a non sprinklered building the diagonal distance of the two furthest points is measured and divided by 2 to arrive at the minimum distance required between exits - 78' (24 m) divided by 2 = 39' (12 m).

Once the number of exits required for each room, space, or group of rooms is known, the arrangement and width of those exits must be determined.

When two exits are required, they must be placed a distance apart equal to or greater than one-half the length of the maximum overall diagonal dimension of the building or area to be served, as measured in a straight line between the exits.

In the IBC, there is a provision that reduces the minimum separation distance to one-third the maximum diagonal dimension of the room or area to be served if the building is fully sprinklered.

Your drawing solution includes a kitchen with an island and a second prep sink. Which electrical outlets must be GFI?

1. all those within 24" (600 mm) of the prep sink and any other water sources

2. all within 36" (900 mm) of the prep sink and any other water sources

3. all within 48" (1200 mm) of the prep sink and any other water sources

4. all within 60" (1500 mm) of the prep sink and any other water sources

2. all within 36" of the prep sink and any other water source

NCIDQ 7.2 ALL electrical receptacles located within 36" (900 mm) of a water source MUST be GFI. (from NFPA 70)

10

The controls for all accessible (barrier free) wall mounted restroom accessories must be located how many inches/mm AFF for a SIDE reach?

9" and 48"

NCIDQ 5.5 ALL accessible (barrier-free) wall-mounted controls MUST be located between 15" (380 mm) and 44" (1100 mm) AFF for a Forward Reach and between 9" (230 mm) and 48" (1200 mm) AFF for a Side Reach.

11

Upper shelves located above an accessible (barrier free) work surface must not exceed:

44"H

NCIDQ 5.7 ALL accessible (barrier-free) upper cabinets or shelves located above a work surface MUST NOT exceed 44” (1100 mm) AFF.

ADA.gov 308.2.2 Obstructed High Reach. Where a high forward reach is over an obstruction, the clear floor space shall extend beneath the element for a distance not less than the required reach depth over the obstruction. The high forward reach shall be 48 inches (1220 mm) maximum where the reach depth is 20 inches (510 mm) maximum. Where the reach depth exceeds 20 inches (510 mm), the high forward reach shall be 44 inches (1120 mm) maximum and the reach depth shall be 25 inches (635 mm) maximum.

12

Clearance around an accessible (barrier free) toilet must be at least:

60" (1500 mm) along the rear wall and 56" (1420 mm) along the side wall

13

Working under the IBC, a designer has calculated that a total exit width of 8 ft is required from a store.
What combination of door widths would meet most exiting requirements?

1. three 36 in doors remotely located

2. a pair of 32 in doors remotely located from one 38 in door

3. one 36 in door remotely located from a pair of 34 in doors

4. three 34 in doors remotely located

1. three 36" doors remotely located

14

You are working on a remodel of a public restroom and are required to bring it up to code when completing your work.
The toilet partitions are currently held off the ground 3 inches.

Based on this information, what design solution should you take to make sure these are partitions accessible?

Raise the toilet partitions to 9 inches minimum AFF at the front and at least one side of the stall.

Source: https://www.ada.gov/regs2010/2010ADAStandards/2010ADAstandards.htm, 306 Knee and Toe Clearance, Figure 306.2 Toe Clearance
All toilet stalls must have toe clearance below the front partition and below at least one side partitions. This clearance must be a minimum of 9 in (230mm) above the floor and extend a minimum of 6 in (150mm) beyond the compartment-side face of the partition. Standard partitions could remain at 3" hight off the ground.

The toe clearance under the toilet stall is literally for the TOES of someone in a wheelchair to be able to swing by/under if necessary. Think about sitting in a wheelchair (or any chair) and how your feet protrude further out than the rest of the chair. That little bit of extra clearance under the toilet partition will help if you are turning around INSIDE the stall.

For instance, if the partition or a solid wall went all the way down to the ground and did NOT have the minimum turning radius or 6" clear beyond the compartment-side face of that partition, if you turned around inside, you could possibly hit your toes on that lower portion of wall! OUCH!

Although toilets should be located 16-18 inches from centerline to wall, relocating the plumbing fixtures is not the correct answer because it does not have to do with the clearance of the partitions that the questions is asking.
