What is the purpose of a pre-functional checklist?

The purpose of a pre-functional checklist is to verify that system components are installed and operational prior to testing. This checklist serves as a critical tool in the commissioning process, ensuring that all equipment and systems are correctly set up and functioning as intended before they undergo further performance testing. By using this checklist, commissioning technicians can make sure that all necessary components are in place, properly connected, and ready to perform their designated tasks. This step is essential in identifying and addressing any issues early in the process, thereby avoiding complications that could arise during later stages of commissioning or system operation. The focus on operational readiness is what makes the pre-functional checklist a vital aspect of ensuring the reliability and efficiency of building systems.
