Which statement correctly describes the scope of Cost Engineering?

• A. It only covers budget preparation for projects.
• B. It concentrates solely on labor rates.
• C. It focuses only on the cost of materials.
• D. It applies scientific principles and techniques to estimation, cost control, business planning and management science, profitability analysis, project management, and planning and scheduling.

Answer: (D)

The main concept is that cost engineering is an integrated discipline that uses scientific and quantitative methods to manage costs across a project’s life cycle. It encompasses estimation, cost control, business planning and management science, profitability analysis, project management, and planning and scheduling, so decisions consider how costs interact with schedule, resources, risks, and returns. The other statements are too narrow: budgeting is only one part, focusing solely on labor rates ignores materials, equipment, and overall cost behavior, and concentrating only on materials misses the broader framework of estimating, controlling, and planning costs throughout the project.
