Preparation & Study Guide
1. What is the primary purpose of a pier-type footing supporting a specialty
structure?
A. To provide decorative support
B. To transfer structural loads to the soil
C. To eliminate the need for anchoring
D. To provide roof drainage
Answer: To transfer structural loads to the soil
Rationale: A footing distributes loads from posts or columns into the supporting
soil and helps prevent excessive settlement.
2. Before excavating a footing, what should be established first?
A. The gutter size
B. The roof color
C. The exact location and layout of the footing
D. The screen mesh density
,Answer: The exact location and layout of the footing
Rationale: Proper layout establishes the correct position and alignment of
structural supports before excavation begins.
3. Which instrument is commonly used to establish and check elevations on a
construction site?
A. Tin snips
B. Builder's level
C. Pipe wrench
D. Utility knife
Answer: Builder's level
Rationale: A builder's level is used to establish elevations, check grades, and
maintain consistent heights.
4. What is the primary purpose of reinforcing steel in a concrete footing?
A. To change the concrete color
B. To increase tensile resistance
C. To reduce footing width
D. To eliminate curing
Answer: To increase tensile resistance
Rationale: Concrete is strong in compression but relatively weak in tension;
reinforcing steel helps resist tensile stresses.
5. What is a vapor barrier primarily intended to control?
A. Structural loads
B. Moisture migration
C. Wind speed
D. Screen tension
Answer: Moisture migration
,Rationale: Vapor barriers are used to limit moisture movement through building
assemblies where required by the design and applicable codes.
6. Why is proper compaction of soil important beneath a footing or slab?
A. It increases paint adhesion
B. It reduces the likelihood of settlement
C. It increases screen density
D. It eliminates reinforcing steel
Answer: It reduces the likelihood of settlement
Rationale: Properly compacted soil provides a more stable and uniform support
condition.
7. What is the principal function of a CMU kneewall in a specialty structure?
A. To provide a low structural wall or base
B. To serve as roof insulation
C. To replace all roof framing
D. To function as a gutter
Answer: To provide a low structural wall or base
Rationale: CMU kneewalls can provide a supporting wall section for enclosures
and related structural components.
8. Excessive water added to a concrete mix can generally result in:
A. Increased strength in all cases
B. Reduced strength and increased shrinkage
C. Elimination of curing requirements
D. Increased reinforcement strength
Answer: Reduced strength and increased shrinkage
Rationale: Excess mixing water can increase the water-cement ratio, which may
reduce strength and increase shrinkage.
, 9. Why is proper curing important for concrete?
A. It allows proper hydration and strength development
B. It eliminates reinforcement
C. It prevents all cracking
D. It makes excavation unnecessary
Answer: It allows proper hydration and strength development
Rationale: Proper curing maintains suitable moisture and temperature
conditions so cement hydration can continue and the concrete can develop its
intended properties.
10.What should be checked before placing a post in a footing?
A. The post's paint color
B. The footing location, dimensions, and anchor arrangement
C. The gutter outlet
D. The screen spline color
Answer: The footing location, dimensions, and anchor arrangement
Rationale: Proper positioning and anchorage are essential to transferring loads
safely from the structure into the foundation.
11.What is a primary consideration when fabricating a screen wall?
A. Wind loads
B. Carpet thickness
C. Interior paint sheen
D. Plumbing fixture size
Answer: Wind loads
Rationale: Screen enclosures are exposed to wind and must be designed,
anchored, and braced for applicable wind conditions.
