Comprehensive Commissioning (Cx)

Commissioning Plan: The Cx Plan provides guidance in the execution of the commissioning process. It outlines the organization, schedule, allocation, resources, and documentation requirements for the Commissioning Process.
 

Owner’s Project Requirements (OPR): a document that details the requirements of a project and the expectations for how it will be used and operated, including project goals, measurable performance criteria, cost considerations, benchmarks, success criteria, training requirements, documentation requirements, and supporting information.
 

Basis of Design (BoD): a document that records the concepts, calculations, decisions, and product selections used to meet the OPR and to satisfy applicable regulatory requirements, standards, and guidelines. The document includes both narrative descriptions and lists of individual items that support the design process.
 

Commissioning Specifications: Commissioning specifications outline the detailed requirements, roles, responsibilities, and processes for verifying that building systems perform as intended during the commissioning phase of construction projects.
 

Design Reviews: a review of the design documents to determine compliance with the OPR, including coordination between systems and assemblies being commissioned, features and access for testing, maintenance, and other reviews required by the OPR and Cx Plan.
 

Pre‑Functional Checklists, Testing and Start‑Up: Pre-functional checklists and testing/start-up are essential early steps in the commissioning construction phase to verify equipment installation and readiness before integrated functional testing.
 

Test, Adjust and Balance (TAB) Report: Documents the verification, measurement, adjustment, and final performance of HVAC or hydronic systems to meet design specifications.
 

Controls Check Out: Verifies the correct wiring, calibration, configuration, and operation of building automation system (BAS) components, such as sensors, actuators, controllers, and sequences of operation, prior to integrated functional testing.
 

Functional Performance Testing (FPT): A dynamic, integrated evaluation of building systems—such as HVAC, electrical, BAS, and life safety—to confirm they operate correctly under simulated real-world conditions, sequences, and failure modes per the Owner's Project Requirements (OPR).
 

O&M Manuals and Warranties: Occurs during project closeout and warranty periods, compiling comprehensive documentation and ensuring contractor obligations for system reliability post-handover.
 

Training Plan: A written document that details the expectations, schedule, budget, and deliverables of the Commissioning Process activities related to training of project operating and maintenance personnel, users, and occupants.
 

Commissioning Report: a document that records the activities and results of the Cx and includes an executive project summary, lessons learned, confirmation of receipt of all major required deliverables, and resolution of all major issues to the satisfaction of the Owner, no later than the expiration of the warranty period.
 

Systems Manual: A system-focused composite document that includes the Commissioning Record, operating manual, maintenance manual and additional information for use by the owner during the Occupancy and Operations Phase. The manual should be coordinated with the OPR and BOD, and it should reflect the final commissioned systems, operating sequences, and maintenance information.
