1. A residential builder is laying out a new foundation on a site where
the soil contains substantial clay and is susceptible to seasonal
volume changes. Which construction practice is MOST important for
reducing the risk of differential settlement and structural
movement?
A. Eliminating all reinforcing steel from the footing
B. Placing footings at inconsistent elevations to follow the grade
C. Providing properly designed footings bearing on suitable, properly
prepared soil
D. Increasing the roof overhang without modifying the foundation
Answer: C. Providing properly designed footings bearing on suitable,
properly prepared soil
Properly designed footings must transfer structural loads safely to
competent bearing material. Unsuitable or poorly prepared soil can
,compress, expand, or shift, producing differential settlement and
cracking.
2. During excavation for a residential footing, the builder discovers
that the bottom of the excavation contains loose, disturbed soil
rather than firm undisturbed bearing material. What should the
builder do FIRST?
A. Pour concrete immediately to lock the soil in place
B. Remove or properly stabilize the unsuitable material and establish an
acceptable bearing surface
C. Add additional roof framing to compensate for the weak soil
D. Install drywall before proceeding with the foundation
Answer: B. Remove or properly stabilize the unsuitable material and
establish an acceptable bearing surface
Footings must bear on suitable material capable of supporting the
intended loads. Loose or disturbed soil should be corrected before
concrete placement rather than concealed by the footing.
3. What is the PRIMARY purpose of reinforcing steel in a reinforced
concrete foundation?
A. To eliminate the need for properly proportioned concrete
B. To increase concrete's resistance to tensile stresses
C. To prevent concrete from curing
D. To make concrete completely waterproof
Answer: B. To increase concrete's resistance to tensile stresses
,Concrete performs very well in compression but is comparatively weak
in tension. Reinforcing steel provides tensile capacity and helps control
cracking and structural deformation.
4. A builder is reviewing a concrete mix before placing a residential
footing. Which factor has the MOST direct effect on the strength
and durability of properly proportioned concrete?
A. Water-cement ratio
B. Color of the aggregate
C. Width of the excavation
D. Number of electrical outlets in the building
Answer: A. Water-cement ratio
The amount of water relative to cement strongly affects concrete
strength, permeability, shrinkage, and durability. Excess water generally
produces weaker and more porous concrete.
5. When installing wood sill plates on a concrete foundation, which
condition is MOST important for protecting the connection from
moisture-related deterioration?
A. Installing untreated wood directly against permanently damp concrete
B. Providing an appropriate moisture barrier between the concrete and
wood where required
C. Painting only the top surface of the sill plate
D. Leaving the sill plate completely unsupported
, Answer: B. Providing an appropriate moisture barrier between the
concrete and wood where required
Concrete can transmit moisture to wood in contact with it. Proper
separation and protection help reduce moisture absorption, decay, and
deterioration of the sill plate.
6. A wall opening is required for a large window in a load-bearing
exterior wall. Which component is generally required to transfer
loads around the opening?
A. Sole plate only
B. Header
C. Ceiling finish
D. Baseboard
Answer: B. Header
A header spans the opening and transfers loads from the structure
above to the supporting wall members at the sides of the opening.
7. Which framing defect creates the GREATEST concern when a load-
bearing stud has been excessively notched without approved
reinforcement?
A. Slightly uneven paint coverage
B. Reduced structural capacity of the member
C. Increased window glazing area
D. Improved thermal performance
Answer: B. Reduced structural capacity of the member
