CaliforniaGeo is pleased to offer a series of online regular meetings we call The Underground  for registered participants.  Many sessions carry AIA Learning Unit credit for an additional fee.  Contact us for details.  Our productions use our Zoom platform, lasting one hour, Noon-to-1pm Pacific Time.  The topic may be an issue, a technique, or a technology—or how certain policies and regulations may affect those.

We will feature a host and presenter, or a panel of two-to-three who will make a short presentation on the subject and then take live or chat-based questions from the audience.  These will be free for CaliforniaGeo professional and affiliate members, and $10 for others. Membership will be verified after registration before access is provided.  Participation is limited.

                                   The Importance of Having a Commissioning Provider for Geo-exchange Projects


The presentation will focus on the importance of having a commissioning provider to be the owner’s consultant through the entire project with services including but not limited to:

  1. Assist with detailing the Owner’s Project Requirements (OPR) prior to hiring the design team.
  2. Plan monitoring, inspections, and testing – really making an inspection and testing plan (ITP) as early as possible in the process and enforcing hold points listed in the ITP. 
  3. Obtain signed and stamped forecasted energy consumption calculation results to protect the owner from long-term operation costs far exceeding the forecasted values. 
  4. Ensure that the sequence of operations is detailed, and that the system works according to the sequence of operations.
  5. Get proper sign-off on progress to hold various parties accountable.
  6. Catching any problems during the warranty period and clearly identifying if issues are design issues or installation issues, as contractors typically get blamed for issues that are related to design.


•   Geo-exchange projects are multidisciplinary and require leadership from people who are subject matter experts to ensure the outcomes are congruent with the Owner’s Project Requirements and the Basis of Design.

•   With many different parts of the system design and construction happening at different stages of the project, it is important to have consistent oversight and an ITP in place to ensure each stage of the project is completed according to plan, and each party is held accountable throughout the process.
