QUESTION: 9

What type of drawing communicates the design intent of a project but does not have the level of detail required for final construction documents?

Finish plan
Space plan
Bubble diagram

Answer(s): C

Explanation:

A bubble diagram is a conceptual drawing used early in the design process to communicate the design intent by showing relationships and adjacencies between spaces in a schematic, abstract form (e.g., circles representing rooms). It lacks the detail required for construction, such as dimensions or specific materials, making it ideal for conveying the overall concept. A finish plan (Option A) is a detailed drawing showing material applications, used in construction documents. A space plan (Option B) is more detailed than a bubble diagram, showing specific layouts and furniture placement, also closer to construction documentation.

QUESTION: 10

A designer has been asked to design a chair and table for a preschool.
Which human factor is MOST important to consider?

Biometrics
Proxemics
Ergonomics
Anthropometrics

Answer(s): D

Explanation:

Designing furniture for a preschool requires considering the physical dimensions and proportions of young children, which is the focus of anthropometrics--the study of human body measurements. Anthropometrics ensures that the chair and table are appropriately sized for preschool-aged children (e.g., seat height, table height) to promote comfort and safety. Biometrics (Option A) relates to biological identification (e.g., fingerprints), not furniture design. Proxemics (Option B) studies personal space and social distances, which is less critical for sizing furniture. Ergonomics (Option C) focuses on comfort and efficiency but is broader and less specific to sizing than anthropometrics, which is the primary concern for children's furniture.

QUESTION: 11

Which wayfinding strategy is recommended when designing a daycare facility?

Artwork throughout corridors
Epoxy flooring throughout the facility
Painted graphics outside classrooms
Not provided in the original question

Answer(s): C

Explanation:

Wayfinding in a daycare facility involves designing visual cues to help young children, who may not yet read, navigate the space easily and safely. Painted graphics outside classrooms are a recommended strategy because they provide clear, visual identifiers (e.g., animal shapes, colors, or symbols) that children can recognize to locate their classroom or other areas. This aligns with the developmental needs of preschool-aged children, who rely on visual and tactile cues rather than text. Option A (artwork throughout corridors) may be decorative but is less effective for specific wayfinding, as it might not provide clear directional cues. Option B (epoxy flooring) is a material choice for durability and safety but does not directly aid wayfinding. Option D was not provided, so it's not considered.
Verified Answer from Official Source:

The correct answer is verified using NCIDQ IDFX content on wayfinding and human factors in design. Exact Extract: The NCIDQ IDFX Reference Manual states, "In facilities for young children, such as daycares, wayfinding strategies should include visual cues like painted graphics or symbols outside key areas to assist non-readers in navigation."

QUESTION: 13

A designer is preparing a programming document for a tenant space.
Which technique would BEST confirm that the available space is adequate for user needs?

Equate the program area to the usable area
Equate the program area to the rentable area
Compare the program area to the building utilization rate
Compare the program area to industry standards for occupancy type

Answer(s): A

Explanation:

During the programming phase, the designer must ensure that the available space meets the client's needs as outlined in the program. The program area represents the total space required for all functions (e.g., workstations, circulation, support spaces). The usable area is the actual space available for occupancy, excluding structural elements and common areas. Equating the program area to the usable area ensures that the space can accommodate all required functions without over- or underestimating the space. Option B (rentable area) includes common areas like hallways, which inflates the space and is not accurate for functional needs. Option C (building utilization rate) is a broader metric for overall building efficiency, not specific to the tenant space. Option D (industry standards) is useful for benchmarking but not for confirming specific space adequacy.
Verified Answer from Official Source:
The correct answer is verified using NCIDQ IDFX content on programming and space planning. Exact Extract: The NCIDQ IDFX Reference Manual states, "To confirm space adequacy, the program area should be equated to the usable area of the tenant space to ensure all functional needs are met."

QUESTION: 15

Fabric for seating in a busy waiting room should have a MINIMUM of double rubs.

Martindale 15,000
Martindale 25,000
Wyzenbeek 10,000
Wyzenbeek 30,000

Answer(s): D

Explanation:

A busy waiting room requires durable upholstery fabric due to high traffic and frequent use. The Wyzenbeek test measures abrasion resistance in double rubs, while the Martindale test uses cycles.

For commercial spaces like waiting rooms, industry standards recommend a minimum of 30,000 Wyzenbeek double rubs for heavy-duty use. Option D (Wyzenbeek 30,000) meets this requirement. Option C (Wyzenbeek 10,000) is too low, suitable for light residential use. Options A and B use the Martindale test, but even 25,000 Martindale cycles (equivalent to about 18,000 Wyzenbeek double rubs) is insufficient for a busy waiting room, where higher durability is needed.
