EXAM 2026/2027 QUESTIONS WITH
VERIFIED ANSWERS & COMPLETE
RATIONALES
**1. When inspecting a construction site in a coastal zone, what
is the primary reason for verifying the elevation of the grade
adjacent to the structure according to the approved
construction documents?**
A. To check for landscaping aesthetics
B. To ensure proper drainage away from the structure
C. To confirm compliance with energy efficiency standards
D. To determine the soil composition for foundation design
**Correct answer:** B
**Rationale:** Verifying the adjacent grade elevation ensures
that water drains away from the structure, which is critical to
preventing moisture intrusion and potential foundation issues in
coastal environments .

**2. Which document should an inspector reference to confirm
that the floor elevation above the adjacent grade matches the
specified requirements for a coastal construction project?**
A. Soil test report
B. Approved construction documents

A. They must be made of pressure-treated lumber
B. They must be treated to resist decay
C. They must be at least 12 inches in diameter
D. They must be reinforced with steel
, 3 | Page
**Correct answer:** B

marine borers pose significant risks .
**4. How does an inspector verify that deep foundation piles are
properly installed?**
A. By visually inspecting the piles above grade
B. By reviewing certified pile reports to confirm installation to
design depth or point of refusal
C. By measuring the diameter of each pile
D. By testing the concrete strength
**Correct answer:** B
**Rationale:** The inspector must review certified pile reports to
verify that piles are installed to the design depth or to the point
of refusal of further penetration .
**5. What should an inspector verify regarding product
approvals in coastal construction?**
