,1. A contractor is installing a 12-inch ductile iron water main in a trench with a
depth of 8 feet in Type B soil. The trench is adjacent to a public roadway with
occasional heavy traffic. According to OSHA 29 CFR 1926 Subpart P, what is the
minimum required distance from the edge of the trench to the nearest wheels of a
loaded dump truck that must be maintained to prevent cave-in?
A. 2 feet
B. 5 feet
C. 3 feet
D. 4 feet
Answer: C. 3 feet
OSHA 29 CFR 1926.651(k)(1) requires that when mobile equipment is operated
adjacent to a trench, the distance from the edge of the trench to the nearest wheels must
be at least 3 feet for trenches 5 feet or deeper in Type B soil, unless the trench is
supported. This minimizes surcharge loading. Options A, B, and D are incorrect
because they do not meet the regulatory minimum for this scenario.
2. A contractor is planning to bore under a state highway to install a 6-inch gas
main. The Wisconsin Department of Transportation (WisDOT) requires a utility
permit. Which of the following conditions is most critical for the contractor to
include in the permit application to ensure compliance with WisDOT's standard
utility accommodation policy?
A. The bore pit must be located at least 50 feet from the highway right-of-way line.
B. The top of the casing pipe must be at least 5 feet below the existing pavement surface.
C. The contractor must provide a traffic control plan that includes a minimum lane width of
12 feet during construction.
D. The contractor must use a slurry-based boring method to minimize settlement.
Answer: B. The top of the casing pipe must be at least 5 feet below the existing
pavement surface.
WisDOT's Facilities Development Manual (FDM) typically requires that the top of any
casing or carrier pipe under a state highway be at least 5 feet below the pavement
surface to protect the integrity of the roadway structure. Option A is not a standard
requirement; the bore pit location varies. Option C is a general traffic control
requirement but not the most critical for a utility permit. Option D is not mandated;
various boring methods are acceptable if they meet specifications.

,3. During a utility construction project, a contractor encounters an uncharted fiber
optic cable that is marked as a 'non-energized' communication line. However, the
cable is located within the excavation zone of a planned electrical duct bank. The
contractor has not received a positive response from the utility owner after 48 hours
of notification. According to Wisconsin's Diggers Hotline law (Chapter 182, Wis.
Stats.), what action must the contractor take before proceeding with excavation?
A. Proceed with excavation using caution, as the cable is non-energized and the 48-hour
waiting period has expired.
B. Excavate only after visually verifying the cable's location by hand-digging within 24
inches of the marked path.
C. Cease all excavation until the utility owner confirms the cable's status or provides a
positive response.
D. Assume the cable is abandoned and remove it to clear the excavation path.
Answer: C. Cease all excavation until the utility owner confirms the cable's status
or provides a positive response.
Under Wisconsin's Diggers Hotline law, if a utility owner does not respond to a locate
request within the required timeframe, the excavator must not proceed until a positive
response is received. The law prioritizes safety and requires confirmation of the utility's
status. Option A is unsafe and illegal. Option B is not sufficient; hand-digging is
required only if the utility is marked, but here the status is unknown. Option D is
incorrect because the cable may still be active.

, 4. A contractor is installing a 24-inch sanitary sewer pipe by open-cut method in a
residential area with high groundwater. The contractor plans to use a well-point
dewatering system. Which of the following is the most important factor to consider
when designing the dewatering system to avoid damage to adjacent structures?
A. The discharge rate of the dewatering pumps must not exceed 500 gallons per minute.
B. The well points must be spaced no more than 10 feet apart along the trench.
C. The drawdown curve must be analyzed to ensure that the water table is not lowered
beneath existing building foundations.
D. The dewatering system must be operated continuously for at least 48 hours before
excavation begins.
Answer: C. The drawdown curve must be analyzed to ensure that the water table is
not lowered beneath existing building foundations.
Lowering the water table can cause soil consolidation and settlement of adjacent
structures. Analyzing the drawdown curve helps predict the zone of influence and
prevent damage. Option A is not a standard limit; discharge rates vary. Option B is a
general guideline but not the most critical design factor. Option D is not a requirement;
pre-drainage time depends on soil conditions.
5. A contractor is reviewing a utility plan that shows a proposed 15 kV underground
electric cable running parallel to a 2-inch gas main. The plans indicate the cable will
be installed in a joint trench with the gas main at a horizontal separation of 12
inches. According to the National Electrical Safety Code (NESC) and typical utility
standards, what is the minimum required horizontal separation between a 15 kV
electric cable and a gas main in a common trench?
A. 12 inches
B. 24 inches
C. 36 inches
D. 48 inches
Answer: B. 24 inches
The NESC and many utility standards require a minimum horizontal separation of 24
inches between electric cables operating above 600 volts and gas mains when installed
in a common trench. Option A is insufficient for safety. Options C and D are more than
required for this voltage level unless additional conditions apply, such as higher
pressure gas lines.
