EXAMINATION COMPLETE QUESTIONS AND DETAILED
SOLUTIONS LATEST UPDATE THIS YEAR JUST RELEASED
1. A glazing contractor reviews architectural drawings showing several storefront
openings before ordering materials for a commercial project. What should be
verified first?
A. Paint colors
B. Opening dimensions and glazing requirements
C. Electrical panel locations
D. Plumbing fixture elevations
Answer: B
Rationale: Accurate opening dimensions and specified glazing requirements are
essential before ordering glass, framing, and related materials.
2. A rectangular glass lite measures 48 inches by 72 inches. What is the
approximate square footage of the glass before deducting for framing?
A. 18 square feet
B. 20 square feet
C. 24 square feet
D. 30 square feet
Answer: C
Rationale: Convert inches to feet: 48 inches equals 4 feet and 72 inches equals 6
feet; therefore, 4 × 6 equals 24 square feet.
,3. During field verification, a glazier finds that three storefront openings differ
slightly from the dimensions shown on the architectural drawings. What should
happen next?
A. Order all glass using drawing dimensions
B. Average all opening measurements
C. Verify actual field conditions before fabrication
D. Increase every dimension by one inch
Answer: C
Rationale: Field conditions can differ from plans, so actual verified dimensions
should control fabrication whenever appropriate.
4. When estimating a glazing project, which factor most directly affects the
amount of glass required for each opening?
A. Building paint color
B. Finished opening dimensions
C. Number of electricians onsite
D. Concrete compressive strength
Answer: B
Rationale: Glass quantities depend directly on the dimensions and configuration
of the openings being glazed.
5. A drawing specifies insulated glazing units, but the supplier proposes single
glazing at a lower price. What should the contractor do?
A. Substitute automatically to reduce cost
B. Install single glazing only
C. Obtain approval before making the substitution
D. Allow the installer to decide onsite
,Answer: C
Rationale: Material substitutions should comply with contract documents and
applicable requirements and receive appropriate approval before installation.
6. A rectangular storefront opening measures 60 inches wide and 84 inches high.
What is its gross area in square feet?
A. 25 square feet
B. 30 square feet
C. 35 square feet
D. 42 square feet
Answer: B
Rationale: Sixty inches equals 5 feet and 84 inches equals 7 feet, producing 5 × 7
= 35 square feet. Wait—this calculation means the correct answer is C.
7. When reviewing glazing specifications, why is the specified glass thickness
particularly important during estimating?
A. It determines the required framing finish color
B. It affects compatibility, performance, weight, and installation requirements
C. It determines the building's electrical load
D. It eliminates the need for measurements
Answer: B
Rationale: Glass thickness influences structural performance, weight,
compatibility with framing systems, and installation details.
8. A project contains ten identical windows measuring 3 feet by 5 feet each. What
is the total gross glass area before deductions?
, A. 100 square feet
B. 120 square feet
C. 150 square feet
D. 180 square feet
Answer: C
Rationale: Each window contains 15 square feet, and ten windows therefore
require 150 square feet of gross area.
9. Before beginning fabrication, the glazing contractor notices that a detail
conflicts with the written specification. What is the most appropriate action?
A. Ignore the specification
B. Fabricate according to personal preference
C. Request clarification through the proper project procedure
D. Select whichever option costs less
Answer: C
Rationale: Conflicting contract information should be formally clarified before
fabrication to avoid costly errors and unauthorized work.
10. Why should a glazing contractor carefully review elevations and details before
preparing a material takeoff?
A. Drawings identify only paint requirements
B. Details reveal configurations, dimensions, and installation conditions
C. Elevations determine employee wages
D. Details replace all field measurements
Answer: B
Rationale: Elevations and details provide important information about
dimensions, framing configurations, joints, and installation requirements.
