**Question 1.** Which OSHA standard (29 CFR 1926) specifically addresses
requirements for excavation and trench safety?
A) Subpart C – General Safety and Health Provisions
B) Subpart P – Excavations
C) Subpart E – Personal Protective and Life Saving Equipment
D) Subpart M – Fall Protection
Answer: B
Explanation: Subpart P of OSHA’s construction standards contains the regulations
for protective systems, soil classifications, and safe access in excavations and
trenches.
**Question 2.** In a Critical Path Method (CPM) schedule, which activity
determines the minimum project duration?
A) Float activity
B) Critical activity
C) Lag activity
D) Lead activity
Answer: B
Explanation: Critical activities have zero total float; any delay to them directly
extends the overall project duration.

**Question 3.** When estimating concrete volume for a slab, which factor must
be added to the calculated volume to account for waste and spillage?
A) 0 %
B) 2 %
C) 5 %
D) 10 %
Answer: C
Explanation: The ACI recommends adding approximately 5 % to the calculated
concrete volume to compensate for over‑fill, spillage, and minor variations.
**Question 4.** Which of the following soil classifications has the highest bearing
capacity for shallow foundations?
A) Clay (CH)
B) Silty sand (SM)
C) Gravel (GP)
D) Loam (ML)
Answer: C
Explanation: Gravel (GP) possesses the greatest shear strength and therefore the
highest bearing capacity among the listed soils.

**Question 5.** The “Call Before You Dig” system in Nevada is administered by
which organization?
A) Nevada Department of Transportation (NDOT)
B) One‑Call Nevada, Inc.
C) Nevada Division of Environmental Protection (NDEP)
D) Nevada State Engineer
Answer: B
Explanation: One‑Call Nevada, Inc. operates the statewide 811 service that
coordinates utility locates before excavation.
**Question 6.** Which type of traffic control device is required at a temporary
work zone on a two‑lane highway with a speed limit of 55 mph?
A) Portable stop sign
B) Flashing amber beacon only
C) Advance warning signs, channelizing devices, and speed‑reduction signs
D) No device if work is less than 24 hours
Answer: C
Explanation: MUTCD mandates a combination of advance warning, channelizing,
and speed‑reduction signs for temporary work zones on high‑speed roadways.

**Question 7.** In the preparation of a hot‑mix asphalt (HMA) mixture, which
test determines the optimum moisture content for aggregate?
A) Sieve analysis
B) Marshall stability test
C) Proctor compaction test
D) Specific gravity test
Answer: C
Explanation: The Proctor test (or Modified Proctor for road work) identifies the
moisture content that yields maximum dry density for the aggregate blend.
**Question 8.** Which of the following is a primary advantage of trenchless pipe
replacement over open‑cut methods?
A) Higher installation speed for large‑diameter pipes
B) Elimination of traffic disruptions and surface restoration costs
C) Ability to install pipe in any soil type without limitation
D) Lower material cost
Answer: B
Explanation: Trenchless techniques avoid extensive excavation, thereby reducing
traffic impacts and the need for surface restoration.
