Nevada C-7 Elevation & Conveyance Contractor exam
ACTUAL EXAM COMPLETE QUESTIONS AND CORRECT
ANSWERS LATEST UPDATE THIS YEAR
SUMMARIZED EXAM COVERAGE
The Nevada C-7 Elevation & Conveyance Contractor exam focuses on safe excavation practices, accurate
grading, and proper installation of drainage and conveyance systems. It emphasizes OSHA trench safety,
soil classification, and protective systems, alongside surveying techniques for establishing elevation and
slope. Candidates must understand pipeline installation methods, including bedding, compaction, and
alignment, as well as stormwater and sewer conveyance principles. The exam also evaluates knowledge
of equipment use, environmental protection, erosion control, regulatory compliance, and quality
assurance through testing and inspections.
MCQs (1–50) – Nevada C-7 Elevation & Conveyance Contractor Exam
1.
A contractor begins trench excavation without identifying soil type, which leads to unexpected
instability; what is the most appropriate corrective action?
A. Continue excavation
B. Classify soil and implement proper protective systems
, Page 2 of 93
C. Increase excavation depth
D. Ignore instability
Answer: B
Rationale: Soil classification determines trench safety requirements and protective measures.
2.
During grading operations, a slope fails to meet design specifications; what is the most appropriate
response?
A. Leave slope unchanged
B. Regrade using proper elevation control tools
C. Increase excavation depth randomly
D. Compact without leveling
Answer: B
Rationale: Accurate grading ensures proper drainage and compliance with design.
3.
Which instrument is most commonly used to establish elevation control on a construction site?
A. Hammer
B. Laser level or survey transit
, Page 3 of 93
C. Drill
D. Wrench
Answer: B
Rationale: Surveying instruments provide accurate elevation references.
4.
A trench deeper than OSHA limits is being excavated; what safety requirement must be implemented?
A. No protection required
B. Trench protection system such as shoring or shielding
C. Increase workers
D. Remove spoil piles
Answer: B
Rationale: OSHA requires protective systems for deeper trenches.
5.
Which factor most directly affects proper pipe flow in a gravity conveyance system?
A. Pipe color
B. Slope and alignment
C. Worker preference
D. Pipe packaging
, Page 4 of 93
Answer: B
Rationale: Gravity systems rely on correct slope for flow.
6.
Which hazard is associated with improper compaction of backfill around pipelines?
A. Improved stability
B. Settlement and pipe damage
C. Faster installation
D. Reduced cost
Answer: B
Rationale: Poor compaction leads to ground settlement.
7.
Which practice ensures compliance with excavation safety regulations?
A. Ignoring soil conditions
B. Using protective systems based on soil type and depth
C. Skipping inspections
D. Removing barriers
Answer: B
Rationale: Safety systems must match site conditions.
