Cost engineering is "the engineering practice devoted to the management of project cost, involving such activities as estimating, cost control, cost forecasting, investment appraisal and risk analysis." "Cost Engineers budget, plan and monitor investment projects. They seek the optimum balance between cost, quality and time requirements."
Skills and knowledge of cost engineers are similar to those of quantity surveyors. In many industries, cost engineering is synonymous with project controls. As the title "engineer" has legal requirements in many jurisdictions (i.e. Texas, Canada), the cost engineering discipline is often renamed to project controls.
A cost engineer is "an engineer whose judgment and experience are utilized in the application of scientific principles and techniques to problems of estimation; cost control; business planning and management science; profitability analysis; project management; and planning and scheduling."
One key objective of cost engineering is to arrive at accurate cost estimates and schedules and to avoid cost overruns and schedule slips. Cost engineering goes beyond preparing cost estimates and schedules by helping manage resources and supporting assessment and decision making. "The discipline of ‘cost engineering’ can be considered to encompass a wide range of cost-related aspects of engineering and programme management, but in particular cost estimating,cost analysis/cost assessment, design-to-cost, schedule analysis/planning and risk assessment." The broad array of cost engineering topics represent the intersection of the fields of project management, business management, and engineering. Most people have a limited view of what engineering encompasses. The most obvious perception is that engineering addresses technical issues such as the physical design of a structure or system. However, beyond the physical manifestation of a design of a structure or system (for example, a building), there are other dimensions to consider such as the money, time, and other resources that were invested in the creation of the building. Cost engineers refer to these investments collectively as "costs".
Cost engineering, then, can be considered an adjunct of traditional engineering. It recognizes and focuses on the relationships between the physical and cost dimensions of whatever is being "engineered". Cost engineering is most often taught at universities as part of construction engineering, engineering management, civil engineering, and related curricula because it is most often practiced on engineering and construction capital projects. Engineering economics is a core skill and knowledge area of cost engineering.
