1. A public works department is evaluating a long-term pavement management strategy for a
network of arterial roads with high traffic volumes. The current pavement condition index (PCI)
averages 65, and the department has a limited annual budget. Which approach best balances
cost-effectiveness and performance over a 20-year horizon?
A. Perform routine crack sealing and chip seals on all roads annually.
B. Apply a thin overlay to roads with PCI between 50 and 70, and reconstruct roads below PCI 30.
C. Reconstruct all roads with PCI below 60 to a uniform standard.
D. Defer maintenance for five years to accumulate funds for full reconstruction.
Answer: B
Rationale: The correct approach is to apply preventive maintenance (thin overlay) to roads in fair
condition (PCI 50-70) and reconstruct only those in poor condition (PCI<30). This maximizes the
benefit of limited funds by extending the life of roads that are still structurally sound. Option A is too
generic and may waste resources on roads needing more intensive intervention. Option C is overly
aggressive and costly. Option D leads to accelerated deterioration and higher future costs.
2. A municipality is updating its stormwater management program to comply with the latest
NPDES Phase II requirements. Which of the following control measures is most critical for
addressing total maximum daily loads (TMDLs) for a receiving waterbody that is impaired by
sediment and nutrients?
A. Public education and outreach on pet waste disposal.
B. Construction site erosion and sediment control.
C. Post-construction stormwater management for new development.
D. Illicit discharge detection and elimination.
Answer: C
Rationale: Post-construction stormwater management (e.g., retention basins, green infrastructure) is
most critical for reducing long-term sediment and nutrient loads from developed areas. While all six
minimum control measures are important, TMDL implementation often requires structural controls to
achieve load reductions. Construction site controls (B) are temporary, and illicit discharge (D)
addresses different pollutants. Public education (A) alone is insufficient.
3. During a major flood event, the public works operations center loses primary communications.
The emergency operations plan designates a backup radio system, but it fails due to a software
glitch. The incident commander decides to use runners to relay messages between field crews and
the command post. This action demonstrates which principle of incident management?
Page 1
,A. Unity of command
B. Redundancy
C. Span of control
D. Resource typing
Answer: B
Rationale: Redundancy is the principle of having backup systems or alternatives to ensure continuity of
critical functions. The use of runners is a low-tech backup when primary and secondary communication
systems fail. Unity of command (A) refers to reporting relationships. Span of control (C) relates to
supervisor-to-subordinate ratios. Resource typing (D) is about categorizing resources by capability.
4. A public works director is evaluating a proposal to implement a managed lane (e.g.,
high-occupancy toll lane) on a congested freeway. Which of the following is a primary equity
concern that must be addressed in the planning process?
A. Potential reduction in overall traffic throughput.
B. Disproportionate impact on low-income drivers who cannot afford tolls.
C. Increased maintenance costs for the public works department.
D. Conflict with state environmental review requirements.
Answer: B
Rationale: Managed lanes that charge tolls can create equity issues by limiting access for low-income
drivers if alternative free lanes become more congested. Federal and state regulations often require
equity analyses. Option A is a performance concern, C is a financial concern, and D is a procedural
concern, but equity is a primary social justice issue.
5. A public works agency uses a computerized maintenance management system (CMMS) to track
work orders. The system generates a report showing that 60% of work orders are completed
within the target time, but 20% are overdue by more than 30 days. The director wants to improve
performance. Which metric is most directly actionable for the maintenance supervisor?
A. Mean time to repair (MTTR)
B. Overall equipment effectiveness (OEE)
C. Percentage of planned versus emergency work orders
D. Customer satisfaction index
Answer: C
Rationale: The percentage of planned versus emergency work orders indicates how reactive the
maintenance program is. A high proportion of emergency work often leads to overdue tasks. By
increasing planned maintenance, the supervisor can reduce backlogs. MTTR (A) is a reliability metric,
OEE (B) is a production metric, and customer satisfaction (D) is an outcome but not directly actionable
for scheduling.
6. A public works contract for a large infrastructure project includes a clause that allows the
owner to terminate for convenience. The contractor has completed 30% of the work when the
owner decides to terminate due to budget reallocation. The contractor submits a termination claim.
Which of the following costs is the owner likely obligated to pay?
A. Anticipated profit on the remaining 70% of work.
Page 2
,B. All costs incurred to date plus a reasonable profit on work performed.
C. Only costs directly attributable to the terminated portion, excluding profit.
D. All costs incurred plus a percentage fee for overhead.
Answer: B
Rationale: Under a termination for convenience clause, the contractor is typically entitled to all costs
incurred for the work performed, plus a reasonable profit on that work, plus costs of terminating (e.g.,
demobilization). Anticipated profit on unperformed work (A) is not allowed. Option C omits profit on
work done. Option D is not standard; overhead is included in incurred costs.
7. A city is considering adopting a complete streets policy. Which of the following design features
would be most effective in reducing pedestrian-vehicle conflicts at a midblock crossing on a
multi-lane arterial?
A. A painted crosswalk with no additional treatments.
B. A raised pedestrian refuge island and a rectangular rapid-flashing beacon (RRFB).
C. A traffic signal at the nearest intersection only.
D. Reducing the speed limit to 25 mph without enforcement.
Answer: B
Rationale: A raised refuge island allows pedestrians to cross one direction of traffic at a time, and an
RRFB significantly increases driver yielding. A painted crosswalk alone (A) provides minimal protection
on multi-lane roads. A signal at an intersection (C) does not help at midblock. Speed limit reduction
without enforcement (D) is insufficient.
8. A public works department is conducting a risk assessment for its water distribution system.
Which of the following threats is most likely to cause a widespread, long-term service disruption?
A. A single vehicular collision with a fire hydrant.
B. A cyberattack that gains access to the SCADA system controlling pumps and valves.
C. A localized water main break due to corrosion.
D. A temporary power outage at the water treatment plant.
Answer: B
Rationale: A cyberattack on SCADA can disrupt operations across the entire system, potentially causing
prolonged outages and contamination. A hydrant strike (A) and a main break (C) are localized and
typically repaired quickly. A power outage (D) may be mitigated by backup generators. Cyber threats
are a high-consequence, high-likelihood risk for modern utilities.
9. An engineer is evaluating two alternative designs for a new bridge. Alternative X has a higher
initial cost but lower annual maintenance costs. Alternative Y has lower initial cost but higher
annual maintenance. Using a life-cycle cost analysis (LCCA) with a discount rate of 4%, which of
the following additional factors is most critical to include for a fair comparison?
A. The aesthetic appearance of the bridge.
B. The expected service life of each alternative.
C. The political popularity of each design.
D. The environmental impact statement requirements.
Page 3
, Answer: B
Rationale: LCCA requires consistent analysis over the same study period; if service lives differ, residual
values must be considered. Aesthetics (A) and politics (C) are not part of LCCA. Environmental impact
(D) is separate. Without accounting for service life, the comparison may be biased.
10. A public works agency is developing a sustainability plan. Which of the following strategies
would most effectively reduce the carbon footprint of its fleet operations?
A. Switching all light-duty vehicles to hybrid models.
B. Implementing a GPS-based route optimization system for all service vehicles.
C. Installing solar panels on the maintenance facility roof.
D. Purchasing carbon offsets for all fuel consumed.
Answer: B
Rationale: Route optimization reduces total miles driven, directly cutting fuel consumption and emissions.
While hybrids (A) reduce per-mile emissions, optimizing routes can achieve larger reductions by
eliminating unnecessary trips. Solar panels (C) offset facility energy use, not fleet fuel. Carbon offsets
(D) do not reduce direct emissions.
11. A municipality is evaluating a 20-year-old landfill for closure under current Subtitle D
regulations. The site has a composite liner but lacks a leachate collection system. The groundwater
monitoring indicates elevated volatile organic compounds (VOCs) above background levels in the
uppermost aquifer. Which of the following is the most appropriate corrective action under RCRA
Subtitle D?
A. Install a groundwater extraction and treatment system to achieve MCLs within 5 years
B. Implement a monitored natural attenuation plan with periodic review every 2 years
C. Design and install a leachate collection system and cap the landfill within 3 years
D. Perform a corrective measures study (CMS) and submit a corrective action plan to the state
Answer: D
Rationale: Under RCRA Subtitle D, when groundwater contamination is detected, the owner/operator
must conduct a CMS to evaluate alternatives. Options A and B are premature without CMS; option C is
incomplete because the cap alone may not address existing contamination.
12. During a public works project, a contractor proposes using a construction method that deviates
from the approved plans but claims it will achieve equivalent performance. The project is funded
by a federal grant with specific Buy America provisions. Which of the following actions by the
public works official is most consistent with federal procurement requirements?
A. Accept the proposal if the contractor provides a sealed performance bond covering the change
B. Reject the proposal unless the deviation is approved via a formal value engineering change proposal (VECP)
C. Allow the deviation if the contractor signs an indemnity agreement holding the agency harmless
D. Approve the change if the new method uses domestic materials and reduces overall project cost
Answer: B
Rationale: Federal grants often require adherence to approved plans and specifications; deviations must
go through a formal VECP process to ensure compliance with Buy America and other provisions.
Options A, C, and D bypass required approvals and could jeopardize funding.
