AJTcx CxA insight
What does a commissioning authority do?
A commissioning authority leads an evidence-based process that connects owner requirements, design intent, installed systems, testing, issue resolution, and operational handover.

The CxA is a process lead
The CxA coordinates the work and makes the evidence easier to follow. The owner, designer, contractor, controls provider, and operator retain their own responsibilities; the CxA helps the team see whether those responsibilities are producing the required result.
What the process can include
Depending on scope, commissioning may include planning, design review, submittal review, construction observation, installation and start-up verification, functional performance testing, issue tracking, training observations, seasonal testing, and final documentation.
Why it matters at handover
A report is most useful when it shows what was reviewed, what was tested, which issues were resolved, and what remains open. That gives the owner and operator a clearer starting point than a collection of disconnected test records.
