NCIDQ IDFX EXAM QUESTIONS AND ANSWERS
The principal consideration in acoustic control in large spaces is the sound absorptive
quality of the ________. - Answers- Ceiling
[Noise reduction within a space: In larger rooms, ceiling treatment is most effective,
while in smaller rooms, wall treatment is more effective.]
These are part of the HVAC system used for return air and generally have no movable
parts or slats for adjustment. - Answers- Vents
[Source: Qpractice NCIDQ Exam Guide, Structural, Mechanical and Plumbing Systems
-Diffusers have direction fins at different angles (sometimes adjustable) to distribute the
air throughout the space.
-Registers (in the floor or wall) can be open, closed, or adjusted somewhere in-between.
-Grilles often used for return air have no movable parts or slats for adjustment.]
In a new lifestyle hotel, the spa suites will have 4 poster canopy beds. How far away
from the sprinkler heads should the beds and panels be? - Answers- 20 inches
[The canopy would be considered an obstruction to discharge as defined in NFPA 13,
8.5.5 Obstructions to Sprinkler Discharge, which restricts continuous or noncontinuous
obstructions less than or equal to 18in (450mm) below the sprinkler deflector.]
What are the variables of noise reduction between two rooms? - Answers- The three
most important variables are the wall's stiffness, the transmission loss, and the common
area between rooms.
A client has requested that special security protection be provided for critical paper files
containing corporate trade secrets, but at a reasonable cost.
In designing the file room, the interior designer should suggest: - Answers- Card
readers at the doors leading to the file room
[Source: Interior Construction Detailing for Designers, Hardware, Electronic Hardware
Card readers would be the most cost-effective solution because they could provide
access control as well as notification if there was an attempt at unauthorized entry.]
The three most common types of metal doors are flush, sash and louvered.
Flush doors have a single smooth surface on both sides. Sash doors contain one or
more glass lights. Louvered doors have an opening with metal slats to provide
ventilation.]
Which of the following would be the correct way to number a fire protection plan in a set
of construction drawings for a high rise office space? - Answers- 5FP4.1
[In order to provide a logical way to organize and refer to the drawings a system of
numbering must be established. There are several ways to do this. The simplest method
uses single numbers beginning with 1.
, -For larger drawing sets where consultants are involved, numbers are preceded with a
capital letter designating the discipline involved. "FP" is used for fire protection.
-For large projects the drawings within each discipline can be grouped; for example:
floor plans could be group 1, The group number is followed by a decimal point then the
sequential numbers start with "1", example FP2.1 (fire protection group 2 page 1)
-For projects in a high rise with different sections the number is proceeded with the floor
number. For example 5FP4.1 (5th floor fire protection group 4 page 1).]
Which method of information gathering entails using photographs from different angles
to create a three-dimensional model? - Answers- Convergent photogrammetry
[Source: Interior Design Reference Manual, 6th Edition, Measurement and Drafting
Convergent photogrammetry entails using photographs from different angles to create a
three-dimensional model. This process takes a long time but is relatively inexpensive.
Stereophotogrammetry entails superimposing one photograph of a building over
another, creating an image that can easily be converted into a 3-D depiction. This
process requires special software and equipment.
Rectified photography is a technique for producing scalable images of building façades.
Orthophotography is a technique for aggregating digital photographs into a single,
three-dimensional image, using sophisticated computer programs.]
When creating a drawing that will be used for reproduction in a magazine, it is best to
use - Answers- a graphic scale
[Magazines and other publications typically reduce original drawings to fit the format of
the publication. Only a graphic scale would enlarge and reduce in the same proportion
as the drawing.]
What kind of drawing is the most common for complex ceiling systems in large
commercial projects? - Answers- Reflected ceiling plan
[Source: Qpractice NCIDQ Exam Guide, Lighting: Reflected Ceiling and Electrical Plans
The reflected ceiling plan is part of the overall architectural drawings and shows the
construction of the ceiling, the location of all the lighting, as well as the location of
sprinklers, smoke detectors, and any other objects in or on the ceiling, such as the
mechanical (HVAC) air diffusers and grilles.]
The circulation of a building is included in what square foot calculation total? - Answers-
Occupant area
[Source: Circulation Defining and Planning, Page 2
The occupant area includes the Net Area (NSF) or programmed areas, plus the
circulation area, including primary and secondary circulation.]
