1. Which of the following best describes the primary role of a Maryland
Utility Construction Technician within underground and surface
infrastructure projects?
A. Designing structural engineering blueprints for highway bridges and
tunnels
B. Performing field installation, maintenance, and inspection support for
water, gas, electric, and telecommunications utility systems
C. Managing procurement contracts and budgeting for state transportation
projects
D. Conducting architectural design reviews for commercial building permits
B
The primary function of a utility construction technician is hands-on field
support involving installation, inspection, and maintenance of utility
systems such as water, gas, electricity, and telecommunications, ensuring
compliance with safety and engineering standards.
, 2. In utility construction environments, what is the most critical reason
for performing a “Call Before You Dig” (811) procedure?
A. To estimate project costs and labor scheduling
B. To request emergency utility repairs before excavation begins
C. To identify and mark underground utilities to prevent accidental strikes
D. To obtain building permit approvals from the county engineering office
C
The 811 system is used to locate and mark underground utilities prior to
excavation, significantly reducing the risk of damaging buried
infrastructure and ensuring worker safety and regulatory compliance.
3. Which safety standard is most directly associated with trenching and
excavation work in utility construction?
A. OSHA excavation and trench safety requirements
B. EPA hazardous emissions standards
C. NFPA electrical fire suppression codes
D. ASME boiler and pressure vessel regulations
A
OSHA excavation and trench safety standards govern protective systems,
soil classification, and safe entry procedures in utility trenching operations
to prevent collapses and injuries.
4. A utility technician is most likely to use which instrument to verify soil
compaction during pipeline installation?
A. Theodolite
B. Nuclear density gauge
C. Multimeter
D. Oscilloscope
B
,A nuclear density gauge is commonly used to measure soil compaction and
moisture content to ensure proper support for installed utility lines and
compliance with engineering specifications.
5. What is the primary purpose of utility mapping and locating in
construction projects?
A. To determine soil chemical composition for foundation design
B. To identify existing underground infrastructure before excavation begins
C. To calculate structural load distribution in pipelines
D. To design traffic detours for construction zones
B
Utility locating and mapping are performed to identify buried
infrastructure such as gas, electric, and water lines to avoid accidental
damage during excavation activities.
6. Which type of utility system is primarily responsible for distributing
potable water to residential and commercial users?
A. Stormwater drainage system
B. Sanitary sewer system
C. Water distribution system
D. Electrical transmission system
C
Water distribution systems deliver treated potable water through
pressurized pipelines to end users for domestic and commercial
consumption.
7. Which tool is most commonly used for detecting underground metallic
utility lines?
A. Ground penetrating radar (GPR) receiver
B. Infrared thermometer
, C. Barometer
D. Hygrometer
A
Ground penetrating radar is widely used in utility locating because it can
detect subsurface metallic and non-metallic objects without excavation.
8. What is the primary function of bedding material in trench
construction?
A. To increase electrical conductivity around buried cables
B. To provide uniform support and protection for installed pipes
C. To chemically treat wastewater before discharge
D. To reinforce asphalt pavement strength
B
Bedding material ensures proper support, alignment, and protection of
buried pipes by reducing stress concentrations and preventing damage
from surrounding soil loads.
9. Which hazard is most associated with confined space entry in utility
maintenance operations?
A. Heat reflection from asphalt surfaces
B. Oxygen deficiency and toxic gas accumulation
C. Excessive wind shear forces
D. Structural steel fatigue failure
B
Confined spaces such as manholes and utility vaults may contain
hazardous atmospheres, including low oxygen levels and toxic gases,
requiring strict safety protocols.
10. What is the primary purpose of shoring in trench excavation?
