Questions & Answers with Detailed
Rationales | Complete Exam Prep &
Study Guide
1. What is the primary purpose of special inspection during construction?
A. To replace the contractor’s quality-control program
B. To provide independent verification that designated work conforms to
approved construction documents and applicable requirements
C. To approve architectural design changes
D. To determine the project’s final contract price
Answer: To provide independent verification that designated work conforms to
approved construction documents and applicable requirements
Rationale: Special inspection is an independent verification function. It
supplements, rather than replaces, the contractor’s responsibility for proper
construction and quality control.
, 2. Who typically establishes which building elements require special
inspection?
A. The concrete supplier
B. The special inspector alone
C. The applicable building code and approved construction documents
D. The equipment manufacturer
Answer: The applicable building code and approved construction documents
Rationale: Special inspection requirements originate from the adopted code and
project-specific construction documents, including the statement of special
inspections when required.
3. What is the best description of an approved testing agency?
A. An agency responsible only for preparing project estimates
B. An organization qualified to perform specified construction-material testing
and reporting
C. A contractor’s payroll department
D. A design-review committee
Answer: An organization qualified to perform specified construction-material
testing and reporting
Rationale: Testing agencies perform prescribed tests on construction materials
or systems and document the results in accordance with applicable standards
and project requirements.
4. During structural steel erection, which condition most clearly requires
immediate attention by a special inspector?
A. Minor paint overspray
B. A connection that does not conform to the approved structural details
C. A temporary office relocation
D. A contractor’s request for additional parking
Answer: A connection that does not conform to the approved structural details
,Rationale: Nonconforming structural connections can directly affect structural
capacity and must be identified and communicated promptly.
5. What is the principal distinction between inspection and testing?
A. Inspection evaluates conformity through observation or examination, while
testing evaluates properties or performance through prescribed procedures
B. Inspection is performed only after construction is complete
C. Testing never requires documentation
D. There is no practical distinction
Answer: Inspection evaluates conformity through observation or examination,
while testing evaluates properties or performance through prescribed
procedures
Rationale: Inspection and testing are complementary activities. Inspection
commonly involves observing construction, while testing uses standardized
procedures to determine material or system characteristics.
6. Why should an inspector review approved drawings before beginning field
inspection?
A. To determine employee wages
B. To understand the specified materials, details, tolerances, inspection points,
and acceptance criteria
C. To redesign the structure
D. To select the general contractor
Answer: To understand the specified materials, details, tolerances, inspection
points, and acceptance criteria
Rationale: Effective inspection depends on knowing what the approved
documents require. Inspectors should not rely solely on field conditions or verbal
instructions.
7. A concrete batch arrives with a delivery ticket showing an excessive elapsed
time since batching. What should the inspector do first?
, A. Automatically approve the load
B. Ignore the ticket
C. Compare the information with the applicable specification and project
requirements and document the disposition
D. Add water without authorization
Answer: Compare the information with the applicable specification and project
requirements and document the disposition
Rationale: Concrete acceptance depends on applicable requirements. The
inspector should verify compliance rather than make an unauthorized field
modification.
8. What is the purpose of concrete slump testing?
A. To directly determine compressive strength
B. To measure concrete temperature
C. To indicate the consistency or workability of fresh concrete
D. To determine cement fineness
Answer: To indicate the consistency or workability of fresh concrete
Rationale: Slump is an indicator of fresh-concrete consistency. It is not a direct
measure of compressive strength.
9. Why is concrete temperature commonly measured during placement?
A. Temperature has no effect on concrete behavior
B. Fresh-concrete temperature can affect setting, strength development,
durability, and placement requirements
C. It determines aggregate color
D. It replaces strength testing
Answer: Fresh-concrete temperature can affect setting, strength development,
durability, and placement requirements
Rationale: Concrete temperature influences hydration and setting behavior and
may be subject to project or code limits.
