Q1. A construction supervisor is reviewing a project where a structural change differs from
the approved drawings. What should the supervisor do first?
A. Allow the work to continue if it appears structurally sound
B. Document the discrepancy and verify the approved requirements before proceeding
,C. Ask the subcontractor to make the decision
D. Remove the completed work immediately
Answer: B.
Rationale: Construction work should follow approved plans and applicable code
requirements. A documented discrepancy should be resolved before proceeding with
potentially nonconforming work.

receive priority from the construction supervisor?
A. Increase the excavation depth gradually
B. Verify utility locations and required excavation precautions
C. Begin excavation using heavy equipment
D. Cover the utility corridor with additional soil
Answer: B.
Rationale: Identifying and protecting existing utilities before excavation helps prevent utility
strikes, injuries, service interruptions, and property damage.
Q3. When reviewing concrete placement plans, which factor most directly affects the
required structural performance of the finished concrete?
A. Color of the concrete surface
B. Concrete mixture specifications and placement procedures
C. Number of workers assigned to cleanup
D. Brand of finishing tools
,Answer: B.
Rationale: The specified mixture, reinforcement, placement, consolidation, curing, and

Q4. A supervisor discovers that a subcontractor is performing work contrary to the approved
construction documents. What is the most appropriate immediate response?
A. Ignore the issue unless an inspector notices it
B. Stop or control the affected work and determine the required correction
C. Permit completion and correct it after final inspection

Q7. Which condition presents a significant hazard when workers are operating around an
unprotected elevated edge?
A. Inadequate fall protection
B. Excessive natural lighting
C. Clean walking surfaces
D. Properly secured materials
Answer: A.
Rationale: Unprotected elevated edges can expose workers to serious fall hazards,
requiring appropriate protective measures.
Q8. When wood framing members are installed, why is accurate alignment important?
A. It improves structural fit and helps ensure walls and assemblies are constructed correctly
B. It eliminates the need for fasteners
C. It prevents all future maintenance
D. It determines the building's paint color
