When project budgeting doesn’t permit the expense of hiring a third-party commissioning agent, many facilities turn to the installing contractor and construction managers to perform commissioning. Many contractors, like PJM, have developed their own customized commissioning forms, while others may choose to work from standard checklists and guidelines from associations such as ASHRAE and NEBB. A commissioning checklist should always be tailored to the specific project, but must always include the basics: pressure testing and signoff, vendor/factory startup and documentation, approved system walk-downs, and performance and sequence testing.
Some facility owners are hesitant to entrust contractors with performing commissioning on their own work, likening it to the fox guarding the henhouse, which is why it is especially important for owners to be involved in the commissioning process. PJM works closely with facility representatives to develop comprehensive, cost-effective commissioning checklists and encourages owner participation and sign-off on the system walk-down. This helps to ensure a clean and thorough commissioning process and allows facility personnel to learn the workings and intricacies of their systems, greatly reducing their learning curve before the building is turned over.
