EXAMINATION COMPLETE QUESTIONS AND DETAILED
SOLUTIONS LATEST UPDATE THIS YEAR JUST RELEASED
1.
A contractor is preparing a bid for installation of a new municipal
sanitary sewer system. Which activity is most directly associated with
the Municipal & Utility classification?
A. Residential kitchen remodeling
B. Sanitary sewer installation
C. Interior painting
D. Commercial roofing
Answer: B
Rationale: Sanitary sewer construction is specifically within the scope
of Alabama's Municipal & Utility classification and is a common utility-
construction activity.
2.
Which of the following is specifically identified by Alabama as work
included within the Municipal & Utility classification?
A. Cabinet installation
B. Sewer projects
C. Residential framing
D. Interior flooring
,Answer: B
Rationale: Alabama's MU classification expressly includes sewer
projects along with water, gas, electric, telephone, paving, and related
municipal work.
3.
A utility contractor must excavate a trench for a new water main. What
should be the first major concern before excavation begins?
A. Selecting the final paint color
B. Locating existing underground utilities
C. Installing permanent pavement markings
D. Ordering interior fixtures
Answer: B
Rationale: Existing utility locations must be established before
excavation to reduce risks of utility strikes, service interruptions,
injuries, and costly damage.
4.
What is the primary purpose of utility locating before excavation?
A. Determine soil color
B. Identify existing underground facilities
C. Establish concrete strength
D. Determine asphalt temperature
Answer: B
,Rationale: Utility locating identifies existing underground infrastructure
so excavation can proceed safely and avoid damaging buried electrical,
gas, water, telecommunications, or sewer facilities.
5.
A trench becomes deeper while workers continue entering it without
protective measures. What is the contractor's greatest concern?
A. Asphalt appearance
B. Trench collapse
C. Concrete curing time
D. Pipe color
Answer: B
Rationale: Unprotected excavations can collapse suddenly, making
trench cave-ins one of the most serious hazards associated with utility
construction.
6.
Which condition can significantly increase the danger of trench
excavation?
A. Stable dry soil
B. Water accumulation
C. Properly installed trench protection
D. Adequate access
Answer: B
, Rationale: Water can weaken trench walls, increase instability, create
drowning hazards, and complicate safe excavation and worker access.
7.
Why should excavated spoil generally be kept away from the edge of a
trench?
A. To improve pipe color
B. To reduce surcharge loading and falling-material hazards
C. To accelerate concrete curing
D. To increase trench depth
Answer: B
Rationale: Spoil placed near trench edges adds loading to the soil and
may fall into the excavation, increasing collapse and struck-by hazards.
8.
A sewer pipe is installed with insufficient slope. What problem is most
likely?
A. Excessive water pressure
B. Poor gravity flow
C. Increased electrical resistance
D. Improved self-cleaning
Answer: B
Rationale: Gravity sewer systems depend on appropriate slope to
maintain flow velocity and reduce sediment deposition, blockages, and
operational problems.
