There is a new trend, however, to extend the concept of “third-party commissioning” to include the commissioning of the facility’s management organization and associated operations and maintenance programs of critical facilities. This is not to be confused with what is typically referred to as “continuous commissioning,” which is focused on the nuts and bolts of critical infrastructure (which is of course a best practice). OPx is applying the commissioning process to the programs and staff required to manage and execute the day-to-day, week-to-week, and year-to-year activities necessary to ensure sustained operations for the life of the facility. Operational commissioning, or OPx, involves engaging third-party validators to oversee and manage the design, development, implementation, documentation, and staff training on the site specific facilities management processes and programs.
