PDD Exam Question - CSI/ Commissioning

Hi @coachmarissayee @coachmikeparaszczak

Can you clarity what it meant by “discrete system”? As well as further explain why Division 26 isn’t the correct answer when it’s defined as the integration of multiple systems, and that appears to be what the question is asking.

Thanks!

Hi Sierra,

An integrated automation system is a system all on its own, and that’s what is meant by “discrete system.” Within buildings, integrated automation systems connect to other building systems to provide streamlined communication.

Because the question is asking for the commissioning spec section of the fully functional system (aka the entire system when connected), the correct answer is Division 1, a general division which combines information from the other systems’ divisions. Since Division 26 only describes commissioning for the integrated automation system alone, it would not be able to describe commissioning requirements for the overall system.

If you have access to a spec book from an old project, I’d encourage comparing spec section 25 08 00 and 01 91 00 which will highlight the differences well. Hope this helps!

Thanks for your question @sierra_gardner and your detailed response @coachmarissayee!
