"Re; 80 KVA UPS and Data Center construction project:
The cut happened smoothly tonight, and all systems are back online.
Thank you to everyone from UTI that worked on this and to our electrical specialists from Gruber Power Services for making this a success!

Jim Johnston
IT Manager

"I just wanted to thank your group for a job well done.
I especially would like to thank Wayne, Rick, Henry, Tony. These guys were very professional in every step of the way. These were all great guys to work with. They were very courteous and very professional.

It was a very satisfying feeling to know the job was in the right hands.

Liz I thank you for the coordination of putting this all together and making it happen.

Again thank you all for a job WELL DONE.

David Zerby
Arizona Department of Transportation

I just wanted to send a follow up email about Rick and the team that completed our UPS and electrical installation of the new 80Kva unit. I have to tell you that the installation is one of the cleanest things I've seen done in 10 years being an IT manager, and I really felt like I never had to worry about a thing the last couple of months (other than the City and their "not so efficient" inspectors).

Every other time I've had something like this done with other vendors; I've always had to micro-manage them and keep them on track. But with the Gruber guys, I would just come in to work, and to my pleasant surprise I'd see another significant portion of work done, totally, cleanly.

Additionally, they were respectful and friendly and I got several comments from people not only in our IT Department, but the folks in Accounting as well (who sit next to the server room) about how good the guys were.

Message to one of our Field Engineers -
I want to extend my personal thanks for the sense of urgency in the way you quickly addressed and diagnosed the problems we encountered with our UPS system last week.


I know it was a hurried time for you, your family & your customer both needed you! And you came through for both.

I am very grateful for the conscientious & professional behavior I am told you displayed by staging on-site to ensure we were able to sustain the UPS until power was restored.

The staff cannot speak much higher of you. Many thanks.
