Sempra Energy - Energy Resources Center Mechanical Upgrade

The Energy Resource Center (ERC) needed an upgrade of the HVAC systems serving the facility.  The HVAC upgrades were intended as a life cycle replacement of aging systems as well as to improve the general energy performance of the facility for future LEED EBOM Certification.  We not only achieved the LEED EBOM Certification but exceeded the standard requirements as we hit Platinum Certifications with these upgrades.
The Scope of Work consisted of:


Domestic Hot Water Boiler Replacement

1. Demolish existing domestic hot water system.
2. Install new domestic hot water boiler (B-1), associated circulating pumps, and appurtenances.

 Heating Hot Water Boiler Replacement

1. Demolish existing heating hot water boiler.
2. Install new heating hot water boiler (B-2), associated pumps, and appurtenances.

 Chiller Replacement

1. Demolish existing chilled water equipment (CH-1, CH-2, CH-3).
2. Provide new roll-up door for chiller room equipment access.
3. Install new chillers (CH-1 and CH-2), associated pumps, and appurtenances.

 Cooling Tower Replacement

1. Demolish existing cooling tower screen wall.
2. Install new cooling tower screen wall for cooling tower yard expansion.
3. Demolish existing cooling towers (CT-1, CT-2, CT-3).
4. Install new cooling towers (CT-1 and CT-2), associated pumps, and appurtenances.
5. Install new non-chemical water treatment and filtration systems.

 Air Handling Unit Replacement

1. Install new equipment platform.
2. Install new air handling units (AHU-1 and AHU-2).
3. Demolish existing air handling units (AHU-1 and AHU-2).
4. Demolish existing chilled water based make-up air unit serving Demo Kitchen.
5. Install new air handling unit (AHU-6).

 Packaged Air Handling Unit Replacement

1. Demolish existing packaged air handling unit (PAH-1).
2. Install new chilled water based air handling unit (AHU-4).  This will be a conversion from an air-cooled system to a water-cooled chilled water based system.
3. Install new VAV and reheat controls for AHU-4 based zone control.

 Packaged DX AC Unit Replacement

1. Demolish existing DX AC unit (AC-3) serving Equipment Demonstration Room (Bake Lab).
2. Install new chilled water based air handling unit (AHU-7).
3. Demolish existing DX AC unit (AC-4) serving Bake Lab Conference Room.
4. Install new VAV box system served from new chilled water air handling unit.

Desiccant Unit Replacement

2. Install new chilled water based air handling unit (AHU-5).

Building Management System (BMS) Upgrade

1. Provide all new controls for scope of work under this project to be fully DDC capable and BACnet compliant with energy management features to track building energy consumption to meet LEED EBOM requirements.

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
Project Cost (multiple projects):  $6,939,265.00

Vista Community Clinic

Construction of the two-story, 11,947 SF medical clinic included 20 exam rooms, three nurse stations, medical records room, full pharmacy, two reception areas (1st & 2nd floor), several office and support areas and a break area with an exterior terrace. The buildings exterior consists of a stucco finish with a decorative stone veneer and cementitious tile roof. An electrical traction elevator service both floors.
The Vista Community Clinic was constructed to LEED Silver & OSHPD specifications.
On this project we faced numerous challenges causing some delays.  The major delays were not being able to get Permitted drawings from the City until 8/19/08 and per the original schedule we were to have these by 6/12/08.  The other major delay we encountered was Rain.  We had 2 weeks of Rain delays on this project during the framing and offsite improvement stages.  Fortunately we were able to make days up with weekend work, long hours and hit the Clinics anticipated Grand Opening in July.  The official Grand Opening to the public was on August 27th and was a complete success!
Project Schedule:  6/9/2008 - 7/8/2009
Final Construction Cost:  $3,770,248.00
