FAQs about EAp1 :

For a building with individual systems per unit, does every single system need to be commissioned?

What kinds of projects must the CxA demonstrate experience on?

What level of authority does the CxA have towards correcting inaccurate or erroneous construction?

Our project is considering LEED after construction has begun. Can we meet the EAp1 requirements and thus be eligible for LEED certification?

Can the CxA be a member of the design or construction team?

What type of certification is the CxA required to have?

The commissioning process turned up a few issues with the commissioned systems that should be corrected. Do we have to correct these issues and include documentation of that as part of our LEED documentation?

Can the CxA be contracted through the general contractor if the owner requires a single contract for the project?

NC-v4 EAp1:Fundamental commissioning and verification

Contractor is not able to comply with Cx Specifications

We have a project where the contractor is not able to comply with the Cx Specifications and Testing Procedures provided by the CxA. The client has requested that the T&C be performed in a way that doesn't add additional cost, but the CxA insists that the T&C follows their requirements. As you can imagine we have a number of problems for the LEED Cx on our project, but in order to know how to proceed I would like to ask the following:

1. For LEED does the CxA have the authority to require the contractor to follow their requirements? Or is their primary role advisory and guidance for the client?

2. How would a LEED Reviewer likely approach the assessment of a project where there was a mismatch between the CxA's Cx Plan testing procedures and the contractors test reports (eg the contractor did not use testing equipment as noted in the Cx Plan)?

1. CxA is beholden to what the owner wants. I'd advise the owner get involved and instruct what they want the Cx to do. 2. A mismatch could be noted in the Issues & Benefits log. The LEED reviewer will accept this. It is then up to the owner to determine if they want the contractor to re-test with the equipment noted in the Cx Plan. Key point, the owner who has the authority over the CxA.

Timothy,   If the CxA was brought on durin design and provided Commissioning Specifications, the contractor bought those specifications and therefore should perform the Commissioning as it is detailed in the specifications.  If the specifications only call out that the contractor needs to provide support and "demonstrate" the functionality of the equipment, it is up to the CxA to determine how that will go.  The CxA and contractors should be performing the Commissioning together so the reports should have the same information, though the contractors reports (start-up et.c) are not typically submitted as part of the LEED online submission.

Thank you David, that helps clear things up for me.
