Complete Exam Prep & Study Guide
1. During a footing inspection, the inspector observes that reinforcing steel
has been placed directly on compacted soil with no approved supports.
What is the primary concern?
A. The concrete will cure too quickly
B. The reinforcement may not achieve the required concrete cover
C. The footing will automatically become over-reinforced
D. The concrete will have excessive slump
Answer: The reinforcement may not achieve the required concrete cover
Rationale: Reinforcing steel must be maintained at the specified location and
concrete cover. Steel resting on soil can lose the required cover and become
vulnerable to corrosion or reduced bond and durability.
, 2. A concrete mix design specifies a water-cementitious materials ratio of
0.45. The contractor proposes adding water at the site to improve
workability. What should the inspector do first?
A. Allow the addition if the concrete looks too stiff
B. Allow unlimited water if the slump remains below 8 inches
C. Verify that the approved mix design and applicable requirements permit the
adjustment
D. Require the concrete to be discarded immediately
Answer: Verify that the approved mix design and applicable requirements
permit the adjustment
Rationale: Additional water can increase the water-cementitious ratio and
reduce strength and durability. Any adjustment must comply with the approved
mix and applicable specifications.
3. A structural steel column is shown on the approved drawings with a
specified base-plate elevation. Field conditions require the column to be
raised by 1 inch. What is the most appropriate inspector response?
A. Approve it because the difference is small
B. Require the contractor to obtain an approved design clarification or
modification
C. Grind the column shorter
D. Increase the bolt torque
Answer: Require the contractor to obtain an approved design clarification or
modification
Rationale: A field change affecting structural geometry should not be approved
solely by the inspector. The design professional or authority having jurisdiction
must determine whether the change is acceptable.
4. Why are anchor bolts in a concrete foundation particularly important to
inspect before concrete placement?
,A. They control concrete temperature
B. They establish the final location and connection of structural elements to the
foundation
C. They eliminate the need for reinforcing steel
D. They prevent concrete shrinkage
Answer: They establish the final location and connection of structural elements
to the foundation
Rationale: Anchor-bolt location, projection, diameter, embedment, spacing, and
alignment affect the structural connection between the foundation and
supported construction.
5. A slab-on-ground is being placed over granular fill. Which inspection finding
presents the greatest concern?
A. The contractor uses a laser screed
B. The granular fill contains uncontrolled soft areas and has not been properly
compacted
C. The slab has construction joints
D. The contractor uses a bull float
Answer: The granular fill contains uncontrolled soft areas and has not been
properly compacted
Rationale: Poor subgrade preparation can cause differential settlement,
cracking, loss of support, and slab failure regardless of the quality of the
concrete placed above it.
6. During masonry inspection, the inspector finds that reinforcing bars in a
grouted cell are displaced significantly from their specified position. What is
the principal concern?
A. Mortar color
B. Reduction in effective reinforcement location and structural capacity
C. Excessive wall insulation
D. Increased brick absorption
, Answer: Reduction in effective reinforcement location and structural capacity
Rationale: Reinforcement must be positioned and supported as required so that
it develops the intended strength and bond within the grouted masonry
assembly.
7. What is the primary purpose of a construction joint in a concrete structure?
A. To eliminate all cracking
B. To provide a planned location for interruption of concrete placement
C. To reduce reinforcement requirements
D. To replace expansion joints in every application
Answer: To provide a planned location for interruption of concrete placement
Rationale: Construction joints accommodate planned interruptions in concrete
placement while maintaining the required structural and durability
performance.
8. An inspector discovers that a concrete placement continued after the
concrete exceeded the specified allowable time from batching. What
should be evaluated first?
A. Paint color
B. Whether the concrete remains compliant with the approved specification and
applicable requirements
C. The contractor's payroll records
D. The building's occupancy classification
Answer: Whether the concrete remains compliant with the approved
specification and applicable requirements
Rationale: Concrete workability, temperature, age, admixtures, and specified
placement limits can affect performance. The inspector should document the
condition and determine compliance rather than make an unsupported
acceptance decision.
