There are things facility managers can do to better position buildings for re-opening, according to an article from Building Operating Management on the FacilitiesNet website.
The overall objective associated with re-opening from a facility management and facility maintenance standpoint must be that of complete readiness with the building operations.
Everything from the lighting of the space to the security, HVAC, and janitorial operations must be performed within the strictest of procedures and industry protocols.
This effort is being performed in several ways that include a strict cleaning protocol recommended by the Centers for Disease Control and Prevention (CDC), as well as performing testing of employees entering a building with temperature scanners.
