1. What is the primary purpose of a utility contractor's
preconstruction site investigation?
A. To determine employee salaries
B. To identify existing utilities, site conditions, access, and
potential hazards
C. To eliminate the need for permits
D. To determine the project's advertising budget
Answer: B. To identify existing utilities, site conditions, access,
and potential hazards
Rationale: A thorough site investigation helps the contractor
identify underground conflicts, soil conditions, access
limitations, environmental concerns, and other risks before
work begins.
2. Before excavating near an existing underground utility, the
contractor should first:
A. Begin excavation with a backhoe
B. Obtain utility-location information and have utilities properly
located
,C. Remove all surface vegetation
D. Compact the area
Answer: B. Obtain utility-location information and have
utilities properly located
Rationale: Existing utilities must be identified and located
before excavation to reduce the risk of service interruption,
property damage, injury, or electrocution.
3. What is the primary purpose of trench shoring?
A. Increase water pressure
B. Prevent trench-wall collapse
C. Improve pipe color
D. Reduce equipment fuel consumption
Answer: B. Prevent trench-wall collapse
Rationale: Shoring and other protective systems protect
workers from cave-ins, one of the major hazards associated
with trenching.
4. Which condition can significantly increase the risk of trench
collapse?
A. Stable compacted soil
B. Water accumulation
C. Properly installed shoring
D. Adequate trench access
,Answer: B. Water accumulation
Rationale: Water can weaken soil and increase instability,
making trench walls more susceptible to collapse.
5. What is the purpose of bedding beneath a buried utility
pipe?
A. To provide uniform support
B. To increase pipe color
C. To eliminate the need for backfill
D. To increase excavation depth
Answer: A. To provide uniform support
Rationale: Proper bedding supports the pipe evenly and helps
prevent point loading, settlement, and damage.
6. Which material is commonly used for granular pipe
bedding?
A. Large concrete blocks
B. Properly graded sand or suitable granular material
C. Scrap metal
D. Organic debris
Answer: B. Properly graded sand or suitable granular material
Rationale: Suitable granular bedding provides uniform support
and allows proper installation around the utility.
, 7. Why should utility trenches be backfilled in controlled lifts?
A. To make excavation deeper
B. To achieve proper compaction
C. To increase pipe temperature
D. To avoid surveying
Answer: B. To achieve proper compaction
Rationale: Placing and compacting backfill in controlled lifts
reduces voids and minimizes future settlement.
8. What is the primary purpose of compaction testing?
A. Determine pipe color
B. Verify that backfill meets required density
C. Measure electrical voltage
D. Determine equipment speed
Answer: B. Verify that backfill meets required density
Rationale: Compaction testing confirms that soil has been
compacted adequately to support pavement, structures, and
other improvements.
9. What does a utility easement generally provide?
A. Ownership of all surrounding property
B. A legal right to install, access, or maintain a utility within a
defined area
