Introduction
This comprehensive examination is designed to rigorously assess the knowledge,
skills, and abilities required of a competent Plans Examiner in the state of Nevada.
The exam evaluates a candidate's proficiency in interpreting and applying complex
building codes, understanding structural and life-safety principles, and ensuring
compliance with state and federal regulations. Utilizing a combination of multiple-
choice and scenario-based questions, this assessment emphasizes real-world
application and sound decision-making. Candidates must demonstrate a thorough
understanding of the plan review process, from verifying code compliance on
structural systems to evaluating MEP designs and accessibility features. Success on
this exam indicates a professional's readiness to protect public health, safety, and
welfare through diligent and ethical plan analysis.
SECTION ONE: QUESTIONS 1–50
,1. A designer proposes a new steel-framed office building in Reno. The building
is irregular in shape and has a lateral force-resisting system with significant
discontinuities in the vertical elements. Which analytical procedure is most
appropriate for determining seismic design forces?
A. Equivalent Lateral Force Procedure
B. Simplified Analysis Procedure
C. Modal Response Spectrum Analysis
D. Nonlinear Static Procedure
🟢 Correct Answer: C. Modal Response Spectrum Analysis
🔴 Explanation: For buildings with irregular configurations or significant vertical
discontinuities, a dynamic analysis procedure such as the Modal Response
Spectrum Analysis is required per ASCE 7. The Equivalent Lateral Force Procedure
is limited to regular structures meeting specific criteria.
2. In accordance with the International Building Code (IBC), which occupancy
classification is assigned to a facility used for the storage of hazardous
materials that are in excess of the exempt amounts?
A. Group F-1
B. Group H
C. Group S-1
D. Group M
🟢 Correct Answer: B. Group H
🔴 Explanation: Facilities that store, use, or handle hazardous materials in
quantities exceeding those listed in the IBC's exempt amounts are classified as
Group H (High-Hazard). This classification triggers more stringent fire protection,
containment, and construction requirements.
,3. A designer is specifying a continuous load on a 120-volt branch circuit. The
load is calculated to be 12 amps. What is the minimum ampacity the branch
circuit conductors must be sized to accommodate, considering the continuous
load requirement?
A. 12 amps
B. 15 amps
C. 16 amps
D. 20 amps
🟢 Correct Answer: B. 15 amps
🔴 Explanation: The NEC requires branch circuit conductors to have an ampacity
not less than 125% of the continuous load. For a 12-amp continuous load, 12
amps × 1.25 = 15 amps. The conductors must therefore be sized for at least 15
amps.
4. During the plan review of a commercial kitchen, you notice that the make-up
air system is interlocked with the exhaust hood. This interlock ensures that:
A. The make-up air operates at a higher volume than the exhaust.
B. The exhaust cannot operate without the make-up air.
C. The make-up air cannot operate without the exhaust.
D. Both systems operate independently for safety.
🟢 Correct Answer: C. The make-up air cannot operate without the exhaust.
🔴 Explanation: The interlock is designed to ensure that the make-up air system
is activated only when the exhaust system is operating. This prevents the
pressurization of the kitchen space and ensures that the exhaust hood is
, effectively capturing and removing grease-laden vapors and combustion
byproducts.
5. The minimum required fire-resistance rating for a fire barrier separating a
Group R-2 occupancy from an attached garage is:
A. 1 hour
B. 2 hours
C. 1/2 hour
D. 3 hours
🟢 Correct Answer: A. 1 hour
🔴 Explanation: The IBC requires a minimum 1-hour fire-resistance-rated
separation between a residential occupancy (Group R-2) and an attached garage.
This is a critical life-safety measure to slow the spread of fire from the garage, a
high-hazard area, into the living spaces.
6. In a concrete mix design, the water-cement (w/c) ratio is primarily
responsible for influencing which of the following properties?
A. Workability only
B. Compressive strength and durability
C. Setting time
D. Air entrainment
🟢 Correct Answer: B. Compressive strength and durability
🔴 Explanation: The water-cement ratio is the single most important factor
affecting the compressive strength and durability of concrete. A lower w/c ratio
