It CITY COUNCIL STAFF REPORT
DATE: July 2, 2014 CONSENT AGENDA
SUBJECT: APPROVE CHANGE ORDER WITH CHEVRON ENERGY SOLUTIONS
FOR ADDITIONAL CONTROLS IN THE I-HUB BUILDING AND
REPLACEMENT CONTROLS FOR THE AIRPORT TERMINAL
FROM: David H. Ready, City Manager
BY: Special Projects Coordinator
SUMMARY
The proposed action would be to approve Change Order #2 to Contract A6375 with
Chevron Energy Solutions Company for additional air conditioning controls in the I-Hub
building, re-connecting the I-Hub to the Cogen Plant and replacement controls for the
Airport Terminal.
RECOMMENDATION:
1. Approve Change Order #2 to Contract A6375 with Chevron Energy Solutions
Company in the amount of $119,273, for air conditioning controls in the I-Hub
Building and $376,959 for replacement controls at the Airport Terminal.
2. Authorize the Finance Director to make required budget adjustments to authorize
the use of the Sustainability Unallocated Program Funds to cover 50% of the cost
of the I-Hub portion of this change order with the remaining 50% to come from
General Fund Reserves and the necessary budget transfer to allocate the
Airport's funds.
3. Authorize the City Manager to execute all necessary documentation.

Chevron Change Order— 1-Hub Controls
STAFF ANALYSIS:
I-Hub: At the time that Chevron Energy Solutions (CES) was hired to conduct the initial
energy audit/study of City facilities the I-Hub building was leased to the County of
Riverside and it was not included in the study. When the I-Hub was established the
building was remodeled and new air conditioning/heating systems were installed but
funds ran out before adequate controls were installed in the building. The building is not
currently served by chilled and hot water from the cogeneration plant.
Change Order No. 2, related to the I-Hub would do three things; first, controls would be
installed on the multi-zone air conditioning equipment which will allow for areas of the
building to be shut off when not in use. Second, connection to cogen would be re-
established and automated controls and metering would be installed on the
cogeneration piping coming into the building so that when excess hot and cold water is
available it can be automatically routed to this building. Third, a touch screen computer
would be installed in the building so maintenance personnel could make on-site
adjustments to the controls as desired. It is estimated that the control portion of the
work should save approximately $7,000 to $9,000 annually, and the cogen
controls/metering will allow for use of chilled and hot water that will otherwise not be
utilized from the cogen plant.
Staff requested that CES provide costs to automate the building, automate the
connection to cogen and to provide for local touch screen computer control. The
negotiated costs from CES totaled $119,273 and are comparable to other quotes
previously reviewed by Facilities Maintenance.
Airport: The Airport Terminal building has several different controls systems as the
facility has grown over time. The primary control system for the building is a third
generation Siemens system which is old and the Airport has been advised that Siemens
can no longer support it unless the airport carries out an upgrade of the system at a cost
of $220,000. The Siemens upgrade will only upgrade the main controls and the
software, providing nothing new in the remainder of the building; basically upgrading
and investing in an outdated system. The other difficulty with utilizing Siemens
equipment is that they must maintain it whereas the proposed system from Chevron is
one that City Staff can maintain and obtain replacement parts directly from the
manufacturer. The Chevron proposal will result in a completely new control system that
is user friendly; total cost of$376,959.

Chevron Change Order—1-Hub Controls
FISCAL IMPACT:
Staff prepared a request of Sustainability for the funding of the I-Hub work and
presented that request to the Commission on June 17, 2014. The Commission declined
to provide for the funding by a vote of 9-1 expressing concern over a dwindling fund
balance. Staff recommends that the Change Order be approved and that the I-Hub
portion be funded 50% from Sustainability Unallocated Program Funds, account 138-
127042691, and 50% from General Fund Reserves,. The Airport will fund its share
from account 416-6501-5000, Airport Unscheduled Capital Projects.

PROJECT TITLE: City Wide Energy Conservation Measures Project
CONTRACT: Energy Services Contract(CU 1361)
CONTRACT NO.: A6375
CONTRACT DATE: July 29, 2013
CONTRACTOR: Chevron Energy Solutions Company
The following changes are hereby made to the Contract:
# Item Cost (Credit)
1. Proposed CR#5, IHUB Chilled water Change Over Controls $58,066.00
(See attached documentation)
2. Proposed CR#14, IHUB Start/Stop Controls $56,807.00
(See attached documentation)
3. Proposed CR#14a, IHUB Touchscreen, alt. 1 $ 4,400.00
(See attached documentation)
4. Proposed CR#7, Airport Terminal DDC Controls $376,959.00
(See attached documentation)
Total $496,232.00
Justification:
Item #1: The IHUB building was not included in the original Chevron study as at the time it was
leased to the County. Now as a City facility it is desirable to have it connected to Cogen chilled
water to take advantage of the cheaper available energy. This change Order would provide the
necessary controls and valves for this to operate.
Item #2: Currently there are no start/stop controls on the equipment at IHUB and therefore
equipment runs when there is no one present, this will add controls.
Item#3: Adds a touchscreen computer at IHUB for making local setting changes.
Item#4: Provides for an completely new control system for the Airport Terminal Building, replacing
a system that parts can no longer be obtained for.

Rev 1 CO#7 (Airport HVAC DDC Controls):
SCOPE OF SERVICES:
(Airport Building—Building HVAC DDC Controls/City of Palm Springs—Airport Retrofit
(Schneider-Electric Energy Management System)):
This scope includes tie in to existing DDC controllers and adding new hardware where required for proper
operation and control.This proposal is based upon multiple site walks at the airport with City Personnel.
The below list was compiled through site walks and information taken off of the existing computer that houses the
Siemens controls.
Scope:
The proposed EMS control system is an open-protocol based system capable of communicating
Lonworks/BACnet/Modbus protocols and will tie into the new city wide EMS frontend system to expand the
Schneider-Electric StruxureWare Control System for the City of Palm Springs airport facility..
Scope:
➢ Remove the existing Siemens control system and retrofit with a new Schneider-Electric EMS control
system and tie seamlessly into the city wide frontend system.
➢ Furnish and install one(1)Schneider-Electric Workstation Professional edition host software suite.
➢ Furnish and install one (1) new Dell Desktop computer with monitor, keyboard and mouse. The
computer will be sized to meet the Schneider-Electric EMS host software.
➢ Furnish and install new Schneider-Electric controllers for the following units:
- Chiller Rm: CH-I,CH-2,CHWP-1,CHWP-2,CHWP-4&CHWP-5
- Cooling Tower Yard- CT-1,CT-2,CWP-1,CWP-2,B-I,HWP-1 &HWP-2

➢ Utilize all existing end devices (sensors, transducers, actuators, control valves, etc.) where practical
for the new controls.
➢ Utilize all existing enclosures to mount the new controllers in.
➢ Utilize all existing control cabling and conduit paths.
➢ Program and test the new Schneider-Electric control system.
➢ Create new system graphic pages.

Also Included:
➢ Provide forty(40)hours of system training.
➢ System warranty (I-yearincluded)after system start-up and commissioning.
Clarifications:
➢ We will require at minimum (13) external static TCP/IP network connection, IP addresses with
internet capabilities for the new controllers at each location installed. This scope will need to be
provided by the City's IT dept/contractor.
➢ We will utilize all existing end devices, enclosures, control cabling, conduit paths, etc. for the new
system controllers.
➢ All labor will be performed on normal business hours(Monday—Friday/7:OOam—4:OOpm). If after
hour labor is required it will be at an additional cost.
➢ if any other controls are required that are not a part of this scope and that are found while doing this
work in the field, CES will immediately notify City of Palm Springs and issue a cost for any added
work not identified in this proposal.
Totalcost.............................................................................$376,959.00
