Project Description:

TMCx Solutions, LLC was retained by Gila River Indian Community to provide LEED Enhanced commissioning for the GRIC Data Center project. This project is a 7,400 square foot 1-story space located at 1576 A S. Nelson Dr.

Scope of Work:

TMCx provided the Prerequisite Fundamental Commissioning as well as Enhanced Commissioning services as required for a LEED certification. We conducted functional testing and pre-functional test verifications, we witnessed major equipment start-ups; assisted with test and balance report verification; and organized and developed project documentation as required to document the Commissioning process

Project Snapshot

  • Owner:  Gila River Indian Community
  • Project Size:  7,400 sq. ft
  • Construction Cost:  $4M
  • GC: Plan Net
  • Year of Completion:  2018

Challenges and Successes

  • Issue: During functional testing, it was observed that the generator would not sync with the UPS while in static bypass mode. It was recommended that the UPS monitor a dry set of contacts located in the ATS (building alarm contact).      Resolution: The electrical contractor pulled additional monitoring wiring and TMCx verified proper operation. Having the UPS sync with the associated generator in all operating conditions is a design requirement and will limit the chance of service interruption during maintenance/testing.
  • As a result of TAB verification, it was identified that the chilled water closed loop system was operating at or above 75 psi. The pressure regulator has a min. set point of 25 psi and expansion tank is factory set at 12 psi.     Resolution: It was recommended to reduce the system pressure to 25 psi, isolate expansion tank, and pressurize to 25 psi and re-connect to system.
