The Contractor shall include the commissioningactivities in the master construction schedule.

1.3 DEFINITIONS

A. Commissioning: The procedures used to assist the Owner and the Architect/Engineer in monitoring the

installation of and facilitating the successful start-up of the building systems verifying their installationperforms as designed and specified; assisting with the permanent transfer of the operation andmaintenance responsibilities of the electrical systems to the Owner and the Owner’s operatingpersonnel. The installation is then “officially” placed into service and becomes the property of theOwner.




B. Start-Up: The initial activation or energizing of equipments or systems for the purpose of demonstrating completeness of installation, utility connections, performance, system operations, andability to perform for it’s specified purpose.

C. Prefunctional Testing: The process of starting the equipment and systems utilizing vendor/contractorstartup and installation checklists in coordination with the CxA's prefunctional documentation toensure systems are operating in compliance with the contract documents, specifications and buildingautomation system sequences, prior to functional validation by the CxA.

D. Functional Performance Test: The process of checking and testing all components, systems, sub-systems, and interfaces between systems to determine if they perform in accordance with the contractdocuments. In this context, “function” includes all modes and sequences of control operation, allinterlocks and conditional control responses, and all specified responses to abnormal emergencyconditions.
