HVAC Pre-Commissioning
Pre-commissioning is an essential part of the commissioning process. This phase starts after mechanical installation is completed and the mechanical team has submitted the quality assurance to the main contractor.
Pre-commissioning is important within construction to ensure all parts of the HVAC system are functional, operational, and safely tested.
*Pre-commissioning activities vary depending on the equipment that is installed.
