Which process ensures that a facility's systems operate as intended?

The process that ensures a facility's systems operate as intended is commissioning. This comprehensive process is crucial in verifying that all systems, such as HVAC, electrical, plumbing, and other mechanical systems, are designed, installed, tested, and functioning according to the specifications laid out during the design phase.

Commissioning is a structured process that often begins in the design phase and continues through construction, testing, and occupancy. It involves the evaluation and validation of systems to ensure they meet the intended performance criteria, which contributes to the overall efficiency and effectiveness of building operations.

In the context of facility management and new construction, commissioning helps avoid future operational issues and maintains the expected performance levels. This proactive approach helps in identifying any discrepancies in system operation before the facility is fully operational, ultimately leading to cost savings through improved energy efficiency and reduced maintenance concerns.

The other processes, while relevant in the lifespan of a facility, do not focus on the assurance of systems operating as intended. The close-out process formally concludes the construction phase and documents project completion but does not entail the testing of systems. The warranty period relates to guarantees of work and materials after project completion but does not ensure performance during operations. Design development is primarily about finalizing designs and preparing for construction, rather than verifying
