What would be the best combination of dimensions for a stair serving a sleeping loft in a condominium where space was at a premium and the floor-to-floor dimension was 9 ft 4 in?
- A.
7 in riser, 10 in tread
- B.
7 in riser, 11 in tread
- C.
8 in riser, 10 in tread
- D.
8 in riser, 11 in tread
Correct Answer
A. 7 in riser, 10 in treadExplanation
If space is at a premium and the floor-to-floor dimension is fixed, minimize the number of treads and the width of one so as to achieve the shortest possible total run. An 8 in riser cannot be used because the code maximum for residential uses is 73⁄4 in. The 7 in riser will work, so select the one with the narrowest tread, 10 in.Rate this question:

- A.
Building expansion
- B.
Seismic events
- C.

During space planning, the designer must locate a 36 in door leading from a corridor, where limited space is available, into another room. One option is to orient the corridor either perpendicular or parallel to the wall separating the corridor from the room and to swing the door in any direction. The door will have a latch only, with no closer. In order to provide for accessibility and minimize the width of the corridor, which of the following door orientations and approach directions would best meet the criteria?
- A.
Hinge side approach, door swings into room
- B.
Front approach, door swings into corridor
- C.
Latch side approach, door swings into corridor
- D.
Front approach, door swings into room
Correct Answer
A. Hinge side approach, door swings into roomExplanation
Required maneuvering clearances indicate that the side approach with the door swinging into the room only requires a minimum of 42 in (assuming the door has no closer). This would allow the use of a 44 in minimum corridor. The front approach (door swings into room) and latch side approach (door swings into corridor) both require a minimum of 48 in. The front approach (door swings into corridor) would require a 60 in corridor (a 36 in door plus 24 in of side clearance).Rate this question:

Correct Answer
A. Post consumer materialExplanation
Post-industrial refers to materials generated in manufacturing processes (trimmings or scrap) that have been recovered or diverted from solid waste. Also called pre-consumer material.

To specify an acceptable type of wall covering, which of the following tests should the designer require that the wall covering pass?
- A.
Steiner tunnel test
- B.
Smoke density chamber test
- C.
Methenamine pill test
- D.
Vertical ignition test
Correct Answer
A. Steiner tunnel testExplanation
The Steiner tunnel test (ASTM E84) is used to measure the flammability of wall finishes and is the test most often required in building codes. The methenamine pill test is for carpet. The smoke density test does not measure flame spread, which is of vital importance. The vertical ignition test is for window coverings.Rate this question:

Correct Answer
A. Corridor construction must be fire-rated.Explanation
The main thing to remember is that corridors are part of the exit access. This means that they are used for calculating travel distance, but they do not necessarily have to be fire-rated (although they usually are). Also, by definition they must be used exclusively for egress.Rate this question:

In specifying new window coverings and track to replace building standard window coverings, what coordination is LEAST important for the interior designer to undertake?
- A.
Asking the electrical engineer if the new light reflectance is detrimental
- B.
Verifying that the building owner does not care about the change in the building's exterior appearance
- C.
Determining if the mechanical engineer objects to the replacement plans
- D.
Checking with the architect to see that the new coverings do not adversely affect the heating of the glass
Correct Answer
A. Asking the electrical engineer if the new light reflectance is detrimentalExplanation
New window coverings can affect the exterior appearance of a building and the heat load, which affects the mechanical system. Also, they can put additional heat stress on glass, causing cracking or breaking. Although light reflectance might be affected, it would be minor and probably not affect the overall light quality in the room.Rate this question:

In creating drawings for paneling that will be suspended from a wall with cleats, the most important piece of information is the
- A.
Dimension between the panel top and ceiling
- B.
Thickness of the wood cleat
- C.
Width of each panel along the wall
- D.
Size of the base
Correct Answer
A. Dimension between the panel top and ceilingExplanation
Although all the information listed in the options needs to be included, the most important is the clearance provided near the ceiling to allow the paneling to be installed. The installation of the panel is not really affected by the thickness of the wood cleat or the size of the base.Rate this question:

In what order of importance should tables for a college library be purchased?
- A.
Durability, cost, then design
- B.

- C.
Finish, flammability, then cost
- D.
Flammability, design, then comfort
Correct Answer
A. Durability, cost, then designExplanation
Because institutional furniture takes much abuse and must last a long time, Durability is important. Quality can be considered a measure of durability. However, Cost is usually an important factor in furniture selection for this type of client, so durability, cost, then design is the best.Rate this question:

When selecting paint for a hospital, which of the following criteria is most important?
- A.
VOC emissions
- B.
Flammability
- C.
Chemical resistance
- D.
Abrasion resistance
Correct Answer
A. VOC emissionsExplanation
For any environment, but especially a healthcare facility, volatile organic compound emissions should be limited, and these can be found in paint and many other materials. Abrasion resistance is incorrect because if abrasion resistance were an important considerations, some material other than paint would be used. Chemical resistance is incorrect because for most areas of a hospital, chemical staining is not a problem. Flammability is incorrect because paint is so thin that it is not regulated; rather, the substrate would need to be flame resistant.Rate this question:

Information regarding standard test methods for evaluating a product can be found
- A.
Through ASTM
- B.
In Sweets Catalog
- C.
At CSI
- D.
On the internet
Correct Answer
A. Through ASTMExplanation
ASTM is the American Society for Testing and Materials and is the organization that writes the majority of standards used in the United States. Although ASTM standards can be researched and purchased on the Internet, "on the internet" is too vague to be an accurate option. CSI is incorrect because the Construction Specifications Institute does not write or distribute standards. Sweets Catalog is incorrect because Sweets Catalog is a source of product data, not standards information.Rate this question:

What should be called out on cabinet drawings to ensure a good fit next to existing construction?
- A.
Scribe pieces at cabinet edges
- B.
Spacers at cabinet backs
- C.
Reveals around all edges
- D.
Blocking, where necessary
Correct Answer
A. Scribe pieces at cabinet edgesExplanation
A scribe piece allows for field cutting so the edge of a cabinet or countertop can be trimmed to fit the irregularities of the wall exactly. A reveal can also be used to disguise the irregularities of the wall, but the question asks about a good fit, which implies direct contact between the cabinet and the existing construction. A reveal piece can also be a scribe piece, but the options include a scribe.Rate this question:

- A.
High-density foam
- B.
Low-density polyurethane
- C.
Combustion modified foam with a low ILD
- D.
Cotton batting
Correct Answer
A. High-density foamExplanation
A medical waiting area with high usage would benefit from a firmer cushion. Cotton batting and low-density polyurethane do not meet this requirement. Also, any material with a low ILD (indentation load deflection) implies a soft cushion.Rate this question:

Color rendering index
- B.
Apparent color temperature rating
- C.
Coefficient of utilization
- D.
Visual comfort probability
Correct Answer
A. Color rendering indexExplanation

- B.
An equivalent gauge of 1/6
- C.

- D.
A pile height that is almost 1/4 in high
Correct Answer
A. 8 surface yarns per inchExplanation
Pitch is the number of ends of surface yarn in a 27 in width. To convert this measurement to gauge (the spacing between stitches) divide 27 in into 216 stitches. This gives 8 stitches/in, or 8 surface yarns/in, so the gauge is 1/8.Rate this question:
