Facilities operations and maintenance encompasses all that broad spectrum of services required to assure your building will perform the functions for which it was designed and constructed.
Operations and maintenance typically includes the day-to-day activities necessary for the building and its systems and equipment to perform their intended function.
According to the International Facilities Management Association (IFMA), the operating life cycle costs of a facility typically are comprised of 2% for design and construction, 6% for O&M and 92% for occupants' salaries. O&M of the elements included in buildings, structures and supporting facilities is complex and requires a knowledgeable, well-organized management team and a skilled, well-trained work force whether the functions are performed in-house or contracted.

To accomplish these objectives, O&M management must manage, direct, and evaluate day-to-day O&M activities and budget funds to support the organization's requirements.
