SoCal Gas Mechanical Upgrades

The mechanical upgrades that were completed at this SoCal Gas facility consisted of improvements to 3 Central Plant buildings.  These upgrades to the various mechanical units ranged from replacement of many of the rooftop air handler units (AHU's), chiller units (Centrifugal Water Chillers to Direct Fired Absorption Chillers), cooling towers, DDC controls, and all associated piping and duct work that accompanied these projects.  I also had the pleasure of replacing the facilities battery backup system for a redundant backup system.
The greatest challenge was that the facility was in full operation while these improvements were all taking place.
Project Schedule (range):  3/23/2009 - 2/18/2011
