The Heating, Ventilation, and Air Conditioning (HVAC) system is one of the most critical building systems in residential, commercial, hospitality, retail, healthcare, education, government buildings, and other types of capital construction projects. The HVAC system is what makes those buildings livable. For project owners, the last thing they want to encounter is to have a failed HVAC system where not only do they risk the complaints from tenants and occupants, but also could face having deserted facilities that no one wants to live at.

Implementing QA/QC checklists for installation work inspection requests, air-balancing-at-air-terminals, pre-commissioning, commissioning and performance tests for HVAC equipment and systems is crucial to reduce the threats of an under-performing HVAC system. Although rectifying non-acceptable workmanship and quality of installed HVAC equipment and systems will be done during the project’s construction stage, nevertheless, it is only during the testing and commissioning stage one can be assured that the HVAC system has been completed successfully.

The pre-commissioning checklists are important to the commissioning process of a building as it allows for a smooth transition to the final testing and acceptance stage of the project. The pre-commissioning of the HVAC system ensures that the installation was done as per the contract design, identifies problems and resolve issues before the commencement of testing, provides an easier and cost-effective solution to remedy issues at the start of the project rather than during commissioning, and helps to provide an early resolution of problems thus reducing delays in commissioning and the overall project acceptance.Usually, there will be pre-commissioning checklists for Air Handling Units (AHU), Fan Coil Units (FCU), Pumps, Cooling towers, Heat Exchangers, Reheat Coils, Variable Air Volume (VAV) Units, Spilt Air Conditioning Units, and others. Using a Project Management Information System (PMIS) like PMWeb where all project management business processes including those for quality management will be the best platform to managing, monitor, evaluate and report on the status of all pre-commissioning checklists. PMWeb visual custom form builder will be used to create those templates for which there will be a separate template for each HVAC equipment and system. The Pre-Commissioning Checklist for the AHU header will include the AHU reference number, HVAC system or zone it belongs to, HVAC subcontractor or vendor name, date, and other details. It will include a detailed list of all items to be checked which will be grouped into their relevant categories.
