Acquiring, operating, maintaining, and disposing of an institutional or commercial facility or a facility system comes with costs. These facility-related costs usually fall into the following categories: Initial costs, including purchase, acquisition, and construction; utility costs; operation, maintenance and repair; demolition and disposal; replacement and refurbishment; residual values, including resale or salvage values or disposal costs; finance charges; and environmental or remediation. Of these costs, those for operation, maintenance, and repair are more than three times the cost of initial construction, and studies show these costs equate to 60-80 percent of a building’s life-cycle costs. The practice of design for maintainability can have a profound impact on an organization’s financial outlay for facilities, so maintenance and engineering managers need to ensure the beginning of construction projects includes a discussion of operations and maintenance issues in order to optimize the building’s life cycle

Managers also need to be sure the organization thoroughly explores the maintainability of a new facility, not only during construction and operations but during feasibility, planning, and design. Maintainability is inherent to building system design, and it ensures the ease, accuracy, safety and economy of maintenance tasks within that system. The purpose of maintainability is to improve effectiveness and efficiency of maintenance.
