SRPMIC Justice Complex

SRPMIC Justice Complex, Scottsdale AZ

Project Description:

The Justice Complex consolidates tribal government departments including Judicial, Court Administration, Prosecutor, Defense Advocate, and Legal Services. A multi-story building houses courtrooms, judicial chambers, court administration, and detainee holding areas and a single-story building houses legal departments. The facility required chilled water supply and return lines to be extended from the existing central plant located on the tribal campus.

Scope of Work:

TMCx was retained by the Community to provide LEED Enhanced Commissioning, including design review, submittal review, execution of pre-functional checklists and functional testing procedures, and operational follow-up prior to warranty expiration.

Challenges and Successes

  • Issue: The sequence did not provide required OA during all operating modes. Additionally, all required sensors were not installed.

          Resolution: A proposed sequence was recommended to the Engineer of Record.  The required tempered air sensors were added and a new sequence was written by TMCx and approved by the EOR. This new program was installed on all outside air units.  With the addition of the required tempered air sensors, the revised SOC’s provided outside air during all operating conditions as well as providing low temperature protection in the event of equipment failure.

  • Issue: Multiple office occupancy sensors were never set-up. Also it appears that sensors are set up at different time off intervals.

          Resolution: The controls contractor worked with the lighting manufacturer and was able to properly monitor all sensors providing occupancy control. Having the occupancy sensors properly programmed and interfaced with BAS front end will allow better HVAC control during off hours, without occupant input.
