QUESTION 1.
,A contractor discovers during installation that the concrete slab edge deviates from
the approved shop drawings by more than the allowable installation tolerance,
preventing proper curtain wall anchorage. What is the most appropriate initial
action?
A. Suspend installation in the affected area and submit the discrepancy for
engineering review.
B. Modify the anchor holes in the field without documentation.
C. Install oversized shims until the framing appears plumb.
D. Continue installation because finish materials will conceal the deviation.
Correct Answer: A. Suspend installation in the affected area and submit the
discrepancy for engineering review.
Explanation: Field conditions that exceed specified tolerances may affect structural
performance and load transfer. The discrepancy should be documented and
evaluated before proceeding. Unapproved field modifications or concealed
deficiencies may compromise code compliance, structural integrity, and warranty
obligations.

QUESTION 2.
An insulating glass unit (IGU) specified for a high-humidity indoor environment
primarily relies on which component to prevent moisture penetration into the cavity
over its service life?
A. Tempered outer lite
B. Secondary edge seal
C. Spacer color
D. Setting blocks
Correct Answer: B. Secondary edge seal.
Explanation: The secondary seal provides structural integrity and long-term
resistance to moisture and gas loss. While the primary seal assists with vapor
, resistance, the secondary seal is critical for durability. The remaining options have
little or no direct influence on long-term cavity moisture protection.

QUESTION 3.
During curtain wall installation, dead-load anchors are incorrectly installed at both
the head and sill of every vertical mullion. Which consequence is most likely?
A. Reduced condensation resistance only
B. Increased acoustic performance
C. Restriction of expected thermal movement leading to stress within the framing
system
D. Improved resistance to building movement
Correct Answer: C. Restriction of expected thermal movement leading to stress
within the framing system.
Explanation: Curtain wall systems are typically designed with one dead-load
connection and movement accommodations elsewhere. Improper restraint at
multiple locations can induce thermal stresses, distortion, or component failure.
The other options do not reflect the primary engineering concern.
────────────────────────────────────────
QUESTION 4.
A glazing crew receives laminated glass panels with minor edge damage that
appears outside the allowable fabrication tolerance specified in the contract
documents. What should the supervisor do?
A. Install the panels if the damage will be concealed.
B. Grind the damaged edge in the field.
C. Replace the damaged interlayer with structural silicone.
D. Reject or quarantine the affected panels pending evaluation by the supplier and
project authority.
, Correct Answer: D. Reject or quarantine the affected panels pending evaluation
by the supplier and project authority.
Explanation: Edge damage may reduce strength and increase the likelihood of
fracture. Materials that exceed specified tolerances should be evaluated before
installation. Concealing or modifying damaged glass without approval may create
safety and liability issues.

QUESTION 5.
Which condition most directly determines whether a framing member satisfies
allowable deflection requirements under design wind loading?
A. Finish color
B. Member stiffness and support conditions
C. Glass tint
D. Sealant curing time
Correct Answer: B. Member stiffness and support conditions.
Explanation: Deflection is governed primarily by structural stiffness, span, loading,
and support configuration. Surface finishes and sealant curing do not significantly
affect structural deflection calculations. Glass tint is unrelated to framing stiffness.
────────────────────────────────────────
QUESTION 6.
A specification requires compatibility testing before applying a structural silicone
sealant. What is the principal purpose of this testing?
A. Verify paint adhesion.
B. Confirm color uniformity.
C. Determine whether adjacent materials adversely affect sealant performance.
D. Increase sealant cure speed.
