NCIDQ Interior Design Qualification 5 — Questions and Answers
Question 1: A designer is coordinating with a mechanical engineer on HVAC diffuser placement. Which drawing should the designer reference to confirm ceiling device locations?
- Structural plan
- Mechanical plan overlaid with reflected ceiling plan (Correct answer)
- Site plan
- Foundation plan
Correct answer: Mechanical plan overlaid with reflected ceiling plan
Comparing the mechanical plan with the reflected ceiling plan ensures HVAC diffusers, light fixtures, and sprinkler heads are coordinated and don't conflict.
Question 2: The term 'fenestration' in building design refers to:
- The arrangement of furniture within a space
- The system of windows, doors, and other openings in a building envelope (Correct answer)
- A method of decorative plasterwork on ceilings
- The process of installing flooring materials
Correct answer: The system of windows, doors, and other openings in a building envelope
Fenestration encompasses all openings in a building's exterior shell, including windows, doors, skylights, and curtain walls.
Question 3: When a designer stamps and signs construction documents, this signifies that:
- The contractor approves of the design intent
- The designer takes professional responsibility for the documents' compliance with applicable standards (Correct answer)
- The client has made final payment
- The building department has reviewed the plans
Correct answer: The designer takes professional responsibility for the documents' compliance with applicable standards
A designer's seal on documents indicates professional accountability for the work's compliance with codes, standards, and professional practice.
Question 4: Which type of adhesive-backed flooring installation method is recommended for areas with radiant floor heating?
- Fully adhered installation using pressure-sensitive adhesive
- Floating installation (Correct answer)
- Double-stick tape installation
- Nailed-down installation
Correct answer: Floating installation
Floating installation allows the flooring to expand and contract with temperature changes from radiant heat without adhesive bond failure.
Question 5: In ergonomics, the standard seated desk height for most adults in the US is approximately:
- 24 to 26 inches
- 27 to 29 inches
- 28 to 30 inches (Correct answer)
- 32 to 34 inches
Correct answer: 28 to 30 inches
Standard desk height in the US is typically 28 to 30 inches, designed to accommodate a range of adult users in a seated position.
Question 6: A 'finish schedule' in construction documents is used primarily to:
- List the project timeline for finish installation
- Indicate the finishes applied to floors, walls, and ceilings in each room (Correct answer)
- Specify the contractor's payment milestones
- Document punch-list items at project closeout
Correct answer: Indicate the finishes applied to floors, walls, and ceilings in each room
A finish schedule is a chart cross-referencing room numbers with specified floor, base, wall, and ceiling materials and finishes.
Question 7: Which fire-protection system uses heat-sensitive bulbs or links to release water only at the sprinkler heads nearest to a fire?
- Deluge system
- Dry-pipe system
- Wet-pipe system (Correct answer)
- Pre-action system
Correct answer: Wet-pipe system
A wet-pipe sprinkler system keeps water in the pipes at all times, and individual heads activate when heat melts their fusible element.
