USING EARNED VALUE MANAGEMENT TO QUANTIFY ECONOMIC, ENERGY, AND ENVIRONMENTAL SUSTAINABILITY IN CONSTRUCTION ACTIVITIES

摘要

Earned value management (EVM) has long been used in the construction industry as a project performance measurement and feedback tool that identifies problems early on in order to make adjustments that keep the project on time and within budget. By following the plan-do-check-act approach of EVM, project managers are able to measure and manage the impacts of their decisions. EVM also provides a much-needed framework for linking together three critical aspects of construction sustainability - economics, energy, and environment - by defining the relationships between equipment cost, fuel use, and air pollution. The EVM sustainability framework presented here utilizes well-known construction planning techniques to allocate resources and schedule activities in order to plan, track, and control equipment costs, fuel use, and air pollutant emissions, thus achieving more sustainable construction activities.
