John. M Roll United States Courthouse

John. M Roll United States Courthouse, Yuma, AZ, 2013

Project Description:

The John. M Roll United States Courthouse, has been named in memory of the judge who worked to make it a reality and who lost his life in the 2011 Tucson shooting that also injured Congresswoman Gabrielle Giffords – Judge John M. Roll. The new federal courthouse will reinterpret and update the classical American courthouse while adapting to the southern Arizona climate by using local sandstone and innovative energy-efficient technologies. The centerpiece of the courthouse will be a large, solar panel canopy that will generate one quarter of the building’s electrical needs while providing shade to employees and visitors. The new complex will house two magistrate courtrooms, judges’ chambers, jury facilities, U.S. Probation and Pretrial Services, District and Bankruptcy Court Services and the U.S. Marshals Service.

Scope of Work:

We worked concurrently with the design team and Sundt Construction to identify and resolve design issues. In addition to basic MEP commissioning, this project had an additional electrical testing component that falls outside normal electrical commissioning. TMCx handled this in-house with our electrical reliability solution.

Challenges and Successes

  • Issue: Both chillers have been observed experiencing nuisance failures.

    From alar history page, it can be observed that failure occurs on low condenser flow during low demand conditions.
  • Issue: Boiler capacity and system flow requirements were not being met during test and balance.      Resolution: The sequence of operation was revised , approved and found operational during functional testing.
