Which of the following best describes the purpose of public works projects?
Provide and maintain public infrastructure and services
Develop private real estate property
Enforce criminal laws
Maximize shareholder profits
Public works projects focus on creating, operating, and maintaining infrastructure for public benefit rather than generating profit or law enforcement. This includes roads, water systems, and public buildings.
Which critical component is essential for assessing the structural integrity of a bridge?
Brand recognition study
Load capacity analysis
Customer satisfaction survey
Marketing analysis
Load capacity analysis evaluates how much weight a bridge can safely bear, which is central to its structural integrity assessment. The other options do not relate to engineering evaluation of bridges.
What type of document is required to demonstrate regulatory compliance before starting a public infrastructure project?
Stakeholder map
Business case
Marketing plan
Environmental Impact Assessment
An Environmental Impact Assessment is a formal report required to show compliance with environmental regulations. Marketing plans, business cases, and stakeholder maps serve different planning purposes but do not fulfill regulatory requirements.
Which cost estimation technique uses a top-down approach based on historical data and overall project scope?
Punch list estimating
Detailed bottom-up estimating
Earned value analysis
Parametric estimating
Parametric estimating applies unit costs derived from historical data to the overall scope, representing a top-down method. Bottom-up estimating breaks projects into detailed components, while earned value analysis is a performance metric.
Who is primarily responsible for ensuring safety standards are upheld on a construction site?
Financial auditor
Marketing manager
Site safety officer
Procurement officer
The site safety officer oversees adherence to safety regulations and conducts safety inspections on-site. Financial auditors, marketing managers, and procurement officers have different responsibilities unrelated to daily safety enforcement.
Which maintenance strategy schedules maintenance at predetermined intervals regardless of equipment condition?
Reactive maintenance
Reliability-centered maintenance
Preventive maintenance
Predictive maintenance
Preventive maintenance is planned at set intervals without regard to actual equipment condition. Reactive maintenance occurs after failure, predictive relies on condition monitoring, and reliability-centered maintenance optimizes processes based on reliability data.
In life-cycle cost analysis, which cost category includes disposal and decommissioning expenses?
End-of-life costs
Design costs
Operation and maintenance costs
Capital costs
End-of-life costs cover disposal, decommissioning, and recycling. Capital costs refer to initial procurement, operation and maintenance cover ongoing use, and design costs relate to planning and engineering.
The Americans with Disabilities Act (ADA) compliance in public infrastructure primarily ensures:
Labor safety standards
Environmental resource protection
Accessibility for persons with disabilities
Historic preservation
ADA requirements mandate accessible routes, ramps, and facilities for disabled individuals. Environmental protection, historic preservation, and labor safety are governed by different regulations.
Which stakeholder engagement technique involves small group discussions to identify concerns?
Focus groups
Online surveys
Mass mailings
Public hearings
Focus groups bring together a small, diverse set of stakeholders to discuss issues in depth. Public hearings are larger and less interactive, while surveys and mailings collect feedback indirectly.
What is the primary benefit of using Geographical Information Systems (GIS) in public works maintenance planning?
Conducting marketing campaigns
Accounting for material costs
Scheduling human resources
Spatial analysis of infrastructure assets
GIS enables mapping and spatial analysis of assets like roads and pipelines to optimize maintenance routes and priorities. It is not directly used for costing, staffing, or marketing.
What is the main purpose of a Regulatory Compliance Audit in public works?
Forecast project revenue
Determine marketing strategy
Evaluate employee performance
Verify adherence to laws and standards
A compliance audit checks that project activities meet legal and regulatory requirements. Revenue forecasting, marketing, and performance evaluation are separate management activities.
In cost estimation, which factor accounts for unforeseen work and errors?
Contingency allowance
Material price variance
Scope creep
Direct labor
Contingency allowance is a budget reserve for unknowns and estimation errors. Direct labor and material variances are planned cost components, while scope creep refers to uncontrolled requirement changes.
Which environmental standard requires measures to control stormwater runoff during construction?
OSH Act
ADA requirements
NEPA review
NPDES permit
The National Pollutant Discharge Elimination System (NPDES) permit regulates stormwater discharges. NEPA covers environmental review, OSHA covers safety, and ADA covers accessibility.
Reliability-centered maintenance focuses on:
Improving stakeholder satisfaction
Preserving system functions based on reliability data
Accelerating construction schedule
Reducing marketing costs
Reliability-centered maintenance uses data on failure modes to optimize maintenance tasks. It is not aimed at marketing budgets, stakeholder satisfaction, or schedule acceleration.
Which budgeting method estimates costs by aggregating individual work packages identified in the Work Breakdown Structure?
Three-point estimating
Rough order of magnitude
Parametric estimating
Bottom-up estimating
Bottom-up estimating sums the costs of each work package from the WBS for a detailed budget. Parametric uses historical rates, ROM gives a high-level estimate, and three-point uses best/worst/most likely scenarios.
A public works department must choose between reactive and preventive maintenance. Which scenario justifies reactive maintenance over preventive?
Safety regulations mandate regular checks
Equipment is inexpensive and failure has minimal impact
Failure can cause environmental damage
Downtime costs are extremely high
Reactive maintenance is cost-effective when equipment is cheap and failures do not critically disrupt operations. High downtime costs, strict safety rules, or environmental risks favor preventive approaches.
During cost control, earned value analysis shows a Schedule Performance Index (SPI) of 0.85. What does this indicate?
Scope has increased
The project is behind schedule
Quality targets are met
Costs are under budget
An SPI below 1.0 means less work has been completed than planned, indicating the project is behind schedule. Budget and quality metrics are assessed by other indices.
A proposed public infrastructure project will affect wetlands. Which regulatory requirement is most critical before proceeding?
OSHA hazard communication plan
Section 404 permit under the Clean Water Act
NEPA categorical exclusion
ADA accessibility guidelines
Section 404 of the Clean Water Act regulates dredge and fill activities in waters and wetlands, making this permit essential. NEPA review, ADA, and OSHA address other aspects of compliance.
In stakeholder analysis, what does a power-interest grid help determine?
Environmental impact thresholds
Engagement strategy based on stakeholder power and interest
Material procurement quantities
Project scheduling milestones
A power-interest grid categorizes stakeholders to tailor communication and engagement strategies. It does not define timelines, procurement amounts, or environmental criteria.
A public works budget forecast includes 5% escalation for inflation and a 10% contingency. If the base estimate is $2 million, what is the total budget?
$2.5 million
$2.1 million
$2.2 million
$2.3 million
Applying 5% inflation ($0.1M) and 10% contingency ($0.2M) to the $2M base yields $2.3M total. Other values omit one of these adjustments or miscalculate percentages.
