What is one responsibility of a CxA in the pre-design phase?

In the pre-design phase, one of the critical responsibilities of a Commissioning Authority (CxA) is to develop the commissioning scope. This scope outlines the objectives, procedures, and measures that will be implemented throughout the commissioning process. It serves as a foundational document that guides all subsequent commissioning activities, ensuring that the project is set up correctly from the beginning. By defining the commissioning scope early on, the CxA helps to ensure that all stakeholders understand their roles and responsibilities, resources are appropriately allocated, and expectations are aligned.

The development of the commissioning scope is vital because it provides clarity on what systems will be commissioned and sets the performance criteria that must be met. This proactive approach helps to mitigate potential issues later in the project by establishing a clear framework for success.

In contrast, conducting site observations, reviewing diagnostic results, and installing systems for testing are typically responsibilities that occur in later phases of a project, such as during design and implementation, rather than in the pre-design phase.
