NCIDQ EXAM QUESTIONS AND
ANSWERS ALL CORRECT
What is a dead load? - Answer- By definition, dead loads are usually permanent, non-
movable loads. Examples are the weight of the building, including the floor, pillars, or
the roofing structure. These are sometimes also referred to as static loads.
What is a live load? - Answer- Loads that are non-permanent, movable loads, such as
people, furniture, and equipment (like a dense filing system), and other more specific
types such as lateral and dynamic loads.
What is Lateral Load? - Answer- Loads that exert force from natural occurrences, like
wind and earthquakes (seismic), or even explosions. These usually exert force in more
directions than downwards.
What is a Dynamic Load? - Answer- Loads created from impacts include
moving/stopping elevators, snow loads, or a car driving across a bridge. The difference
is that these forces change more quickly than static or other types of live loads.
Most common stud size and spacing residential design - Answer- 2x4 wood studs, 16"
OC
What is the framing piece called at the top of an opening for door or window? - Answer-
Lintel or headers
Which of the following describes a "trimmer"?
a. A piece of timber laid horizontally
b. A wood member in a floor or roof used to support a header
c. A framing member that crosses and supports the ends of joists, transferring the
weight of the joist to parallel joists
d.A stud above a door opening or below a window sill - Answer- b. A wood member in a
floor or roof used to support a header
Most common sheet size for GYP - Answer- 4x8
What is the difference between type R gyp and type X gyp? - Answer- These are used
for fire-rated partitions and are more fire-resistive than Type R boards. The core in Type
X boards contains noncombustible fibers (fiberglass) mixed with gypsum. If subjected to
fire, they maintain their structural integrity for a longer time than Type R boards.
,Minimum slope for plumbing drainage - Answer- The minimum slope is 1/4 inch per foot
for pipes 2-1/2 inches (63.5 mm) diameter or less, and 1/8 inch per foot for pipes 3 (76
mm) to 6 inches (152 mm) in diameter.
How is wastewater removed through the sanitary sewer system?
a. vents
b. valves
c. gravity
d. pressurization - Answer- c. gravity
Low Voltage Systems - Answer- Use 50 Volts or less. Common Volts: 48v, 24v, 12v
fire containment - Answer- limits the spread of a fire through compartmentalization. The
aim is to contain a fire and limit its spread. The first goal of containment is to allow
occupants to escape the building. Next, containment protects the unaffected parts of the
building or adjacent buildings.
fire suppression - Answer- uses life safety equipment for fire detection, suppressing
smoke and flame, alarms, and extinguishers.
NFPA 72 - Answer- NFPA 72 sets specific requirements for installation, location, and
maintenance for smoke detection systems.
NFPA 101 - Answer- NFPA 101 specifies requirements for flame detection alarm
systems or radiant energy-sensing systems.
In residential design, where are smoke detectors required? - Answer- Codes require
smoke detectors within and outside of every sleeping room or area. They are also
required at the head of every stair, on every level, including the basement.
What is the typical sprinkler spread and what is the range of SQFT each head is
required to cover? - Answer- 12ft - 15ft diameter spread, 90-200 SQFT coverage
Fire Extinguisher max mounting height and weights - Answer- Up to 40 lbs (18 kg): top
a maximum of 5 feet (1524 mm) above the floor.
Over 40 lbs (18 kg): top a maximum of 3.5 feet (1067 mm) above the floor
Fire Damper - Answer- A device placed in a duct that is designed to automatically close
when subjected to a certain increase in temperature or with the detection of smoke.
Handrail mounting height ADA - Answer- 34-38" AFF
basement emergency escape window dimensions - Answer- Sill max 44" above floor
24" min clear opening height
, 20" min clear opening width
Articulation class - Answer- another measure of the finished ceiling's absorption and
reflection of sound, but specifically affects speech clarity in an open office environment.
Ceiling Attenuation Class - Answer- (CAC) is a ceiling system's ability to reduce sound
transmission (not absorption) from one room to another when the rooms share the
same plenum space.
Resilient channels - Answer- are used to improve the acoustical properties of a wall by
isolating the wallboard from rigid attachment to the framing.
The absorption of material is defined by the ratio of the sound intensity absorbed by the
material to the total intensity reaching the material is called the:
a. sound absorption average
b. noise criteria
c. coefficient of absorption
d. sound transmission - Answer- c. coefficient of absorption
In addition to analyzing space needs, the requirements for a client's work flow or
business process should be compared with the available space.
Which workflow type does not have strict organized method of work flow?
a. departmental
b. cooperative
c. network
d. linear - Answer- c. network
With a network workflow organization, there is no strictly organized method of workflow
A building that has a platinum rating has been designed and certified under which of the
following systems?
a. LEED
b. Institute for Market Transformation to Sustainability
c. National Association of Home Builders Green Standards
d. Green Building Initiative - Answer- a. LEED
When square footage needs have not been pre determined or pre defined, how can the
needs can be determined?
a. by the number of people that need to be accommodated
b. by an object or piece of equipment
c. by a specific activity that has its own clearly specified space
d. all of the above - Answer- d. all of the above
