Here are a couple of pics from an "upgrade" that Trane did. Now, Trane did use a sub for the electrical but I am not sure how much Project Management was used. And, was there any commissioning done? Since I am now planning for the rework I can tell you that there was no check-out or commissioning. I'll put the updated pics later. If you were wondering this was from the Trane office in Fresno, CA. Good news the PM moved to Simens in Fresno, CA. Good luck customers!!
