If a system was designed to operate in lead/lag, but lead/standby was implemented, it would not be able meet the flow requirements during the highest load periods.

After 25 years, this will be my final contribution to Engineered Systems’ Commissioning column.

OPRs are intended to document, in clear, concise, and verifiable terms, the definition of success for the project.

The more automated and complex a building is, the more important it is to clarify control system technical requirements.

With proper planning early in the construction phase, commissioning activities do not need to significantly impact the critical path of construction.

The event is scheduled for May 2-5, 2023, at the Omni Fort Worth in Texas. 

The earlier the commissioning professional can review design documents and provide feedback on compliance, the less potential rework the design team may need to do.

If the owner is not committed to the success of commissioning, the commissioned project will not be as successful as it could be.

Regardless of how automated a system is, its optimal operation will depend on monitoring and human intervention.

Systems documentation is critical, because each building’s systems are unique and designed by different engineers for different purposes in different climates in different architectural enclosures in different code jurisdictions.
