1. During a commercial building inspection, the primary purpose of
verifying that the approved construction documents are available on-
site is to ensure that:
A. The contractor has a copy for estimating purposes.
B. The inspector can compare installed work with the approved design
and code requirements.
C. The owner can make design changes during construction.
D. Material suppliers can verify quantities.
B. The inspector can compare installed work with the approved design and
code requirements.
Rationale: Approved construction documents serve as the official reference
for inspections. Inspectors verify that the work conforms to the approved
plans, specifications, and applicable building code requirements before
approving each stage of construction.
2. Which occupancy classification generally includes office buildings used
for administrative, professional, or service-type transactions?
, A. Group A
B. Group B
C. Group F-1
D. Group M
Rationale: Business occupancies include offices, professional services,
banks, government offices, and similar facilities where administrative and
service functions occur.

B. Ignore the deficiency if welding is complete.
C. Reject the work until corrective action is taken.

Rationale: Structural connections are critical life-safety components. Any
deviation from approved details requires correction before approval
because connection integrity directly affects structural performance.
4. The minimum number of required means of egress from a story
primarily depends on:
A. Roof slope.
B. Exterior wall finish.
C. Occupant load and building configuration.
D. Type of flooring.
Rationale: Building codes establish minimum exits based primarily on
occupant load, travel distance, and building layout to ensure occupants can

A. Improve sound insulation only.
, B. Limit the spread of fire and smoke for a specified period.
C. Support roof drainage.

slowing fire and smoke spread to protect occupants and allow emergency
responders additional time.
6. Which construction type generally provides the greatest level of fire
resistance?
A. Type V
B. Type III
C. Type II
D. Type I
Rationale: Type I construction requires the highest fire-resistance ratings
for structural elements and is commonly used in high-rise buildings and
large commercial structures.
7. An inspector should verify that emergency exit signs are:
A. Decorative only.
B. Installed only near elevators.
C. Properly illuminated and located along the means of egress.
D. Painted the same color as adjacent walls.
