The objective of systems commissioning is to bring a building’s HVAC systems from a state of static completion into dynamic operation.The commissioning process requires many specialized operations by separate persons or organizations. When those operations are not made a part of the construction contract requirements by adequate specifications, the contractor has no basis for pricing the work; consequently, the work is not done under the contract.This paper provides guidance for planning and specifying HVAC systems commissioning work including the cleaning and identification of equipment and piping, cleaning and degreaslng piping systems, chemical treatment program, lubrication, graphic operating instructions, operating and maintenance manuals, control system checkout, preparation for testing and balancing, and instruction of operating and maintenance personnel.Units: I-P
