Planning and Estimating
1. What is the primary purpose of reviewing masonry
plans before beginning construction?
A. To determine the color of the contractor's equipment
B. To eliminate the need for field measurements
C. To identify the scope, dimensions, materials, details,
and construction requirements
D. To determine the contractor's tax liability
Answer: To identify the scope, dimensions, materials,
details, and construction requirements
Rationale: Careful plan review helps the contractor
understand the complete scope of work, identify
required materials, recognize structural details, and
avoid costly omissions or conflicts.
2. A wall is 40 feet long and 8 feet high. How many
square feet of wall area does it contain?
A. 160 sq. ft.
B. 240 sq. ft.
C. 320 sq. ft.
D. 480 sq. ft.
Answer: 320 sq. ft.
,Rationale: Wall area is calculated by multiplying length
by height: 40 × 8 = 320 square feet.
3. A standard 8-inch × 8-inch × 16-inch CMU nominally
covers approximately how much wall area?
A. 0.50 sq. ft.
B. 0.89 sq. ft.
C. 1.25 sq. ft.
D. 1.78 sq. ft.
Answer: 0.89 sq. ft.
Rationale: The nominal face dimensions are 8 inches by
16 inches, or 128 square inches. Dividing by 144 gives
approximately 0.89 square feet per block.
4. Approximately how many standard 8-inch × 8-inch
× 16-inch CMUs are required for 1,000 square feet
of wall, before allowing for waste?
A. 750
B. 900
C. 1,125
D. 1,500
Answer: 1,125 CMUs
Rationale: Each block covers approximately 0.89 square
feet. Dividing 1,000 by 0.89 gives approximately 1,124
blocks, normally rounded up to about 1,125.
5. When estimating masonry materials, which factor
should generally be included in addition to the
calculated quantity?
A. Only the contractor's profit
B. Only transportation time
C. An allowance for waste and cutting
D. The customer's property tax
Answer: An allowance for waste and cutting
,Rationale: Breakage, cuts, damaged units, layout
adjustments, and other losses can increase material
requirements beyond the theoretical quantity.
6. A footing is designed to require six cubic yards of
concrete, but one cubic yard is left over. What is the
most appropriate handling of usable excess
concrete?
A. Wash it into a storm drain
B. Dump it into an unapproved excavation
C. Leave it on the street
D. Return it using the delivery process or dispose of it at
an approved location
Answer: Return it using the delivery process or dispose
of it at an approved location
Rationale: Concrete and cementitious materials should
not be discharged into streets, storm drains, or other
unauthorized locations.
7. Which document normally provides the detailed
requirements for materials, workmanship, finishes,
and installation procedures?
A. Daily time sheet
B. Project specifications
C. Equipment fuel log
D. Payroll register
Answer: Project specifications
Rationale: Specifications supplement the drawings by
describing required products, standards, workmanship,
finishes, and other project requirements.
8. What is the best reason to verify dimensions in the
field before ordering masonry materials?
A. To avoid reading the plans
B. To eliminate all waste
C. To confirm actual conditions and identify
, discrepancies with the drawings
D. To change the project scope without authorization
Answer: To confirm actual conditions and identify
discrepancies with the drawings
Rationale: Existing conditions can differ from drawings.
Field verification helps prevent incorrect quantities,
layouts, and costly rework.
9. A masonry wall is 25 feet long and 6 feet high. If
openings total 20 square feet, what is the net
masonry area?
A. 100 sq. ft.
B. 130 sq. ft.
C. 150 sq. ft.
D. 170 sq. ft.
Answer: 130 sq. ft.
Rationale: Gross area is 25 × 6 = 150 square feet.
Subtracting 20 square feet of openings leaves 130
square feet.
10. Which item is most important when estimating
labor for a masonry project?
A. The color of the contractor's truck
B. Wall height, layout complexity, production rate,
access, and material handling
C. The customer's preferred music
D. The age of the project plans
Answer: Wall height, layout complexity, production rate,
access, and material handling
Rationale: Labor productivity is strongly affected by
wall geometry, elevation, access, handling distances,
details, and crew production rates.
