RECOMMENDED ACTION
City Council approve the performance specifications and award the design -build contract for
the Photovoltaic System and Shade Structures for the Santa Clarita Transit Maintenance
Facility, Project F1016, Federal Transit Administration, American Recovery and
Reinvestment Act, Funding Project D2009-TGGR-003, to Stronghold Engineering, Inc., in
the amount of $4,177,100, and a 5 percent contingency in the amount of $208,855, for a total
not to exceed $4,385,955.
.2. Authorize the City Manager or designee to execute all documents, subject to City Attorney
approval.
BACKGROUND
The Transit Maintenance Facility (TMF) was designed to be environmentally sensitive, using
state-of-the-art energy efficiency and sustainable building methods. This facility was also the
first, but not the last, Leadership in Energy and Environmental Design (LEED) certified building
in the City and received a Gold rating by the United States Green Building Council (USGBC).
In spring 2006, the City of Santa Clarita's TMF became operational, with the capability of
producing on-site electrical power due to construction of a solar canopy as part of the'project.
The existing solar canopy also provides midday shade for 20 commuter buses, minimizing the
time and energy required to cool the buses with air conditioning prior to service. This solar
APPROVED
canopy, funded through the Southern California Edison Self -Generation Incentive Program,
generates approximately 12 percent of the electricity demand of the entire facility (45 percent of
the TMF's administration building energy demand) during the highest demand and peakrate
periods of the day, amounting to approximately 175,000 kilowatt hours (kWh) of electricity
annually.
The City submitted an application to the Federal Transit Administration (FTA) for funding
through the American Recovery and Reinvestment Act (ARRA), Transit Investments for
Greenhouse Gas and Energy Reduction (TIGGER) grant program, proposing to add photovoltaic
(PV) modules at the TMF to generate enough electricity to offset up to 95 percent of the electric
power consumed at the TMF site. On September 22, 2009, the City was one of 43 agencies to be
awarded funds through the grant program. The City's award of $4,620,000 was the fifth highest
in value for the TIGGER program.
Additionally, on March 26, 2010, the City applied for a reimbursement from Southern California
Edison's California Solar Incentive Program for a photovoltaic system. The program was
established to provide a financial incentive for the installation of new, self generation equipment
installed to meet a portion of the electric energy needs of a facility. This program had
authorization to receive applications for a reimbursement rate of $0.26 per kilowatt provided the
self generating equipment would be installed and operating within a year of approval. Southern
California Edison approved the City's application and reserved a total of $260,000 for
reimbursement over five years for the proposed project.
On May 4, 2010, the City received 5 proposals in accordance with the Request for Proposals. An
evaluation panel was formed, consisting of staff members from Capital Improvement Projects,
Transit, Technology Services, General Services, and outside consultants. The panel evaluated the
5 technical proposals and interviewed the top 4 companies as follows:
Company
Stronghold Engineering, Inc.
Peterson -Dean Inc, dba PetersonDean
A.J. Kirkwood & Associates, Inc.
DRI Energy
USS Cal Builders
Location
Riverside, California
Newark, California
Tustin, California
Irvine, California
Stanton, California
Consistent with FTA guidelines, the City is required to rank design -build teams based solely on
their technical qualifications and understanding of the project needs prior to any discussions
concerning proposed costs. Based on technical qualifications and methodology proposed for the
project, the evaluation panel recommends Stronghold Engineering, Inc., as the design -build team
forte Photovoltaic Canopy System.
The proposal by Stronghold Engineering, Inc., recommends PV modules be placed on top of.3
canopies that will generate electricity while providing shade for the City's transit fleet.
Additional PV modules will be placed on top of the TMF's bus wash building. The estimated
calculated energy production for this design is 970,532 kWh per year. This energy will no longer
need to be purchased from Southern California Edison, saving the City approximately $135,875 a
year in electricity bills. With the addition of this system, the estimated total energy -production at
the TMF site will be 1,145,532 kWh per year.
Stronghold Engineering, Inc., will maintain the existing and new photovoltaic system for three
years after the acceptance of the system. The proposed photovoltaic modules have a 25 -year
manufacture warranty and all other equipment has a 10 -year manufacture warranty. It is
anticipated that after 25 years of energy production, the system will be operating at 80 percent of
the calculated production, based on material degradation. The systems electrical production will
be monitored and accessible 24 hours a day by a Deck Monitoring system, via an internet-based
website.
Staff recommends awarding the design -build contract to Stronghold Engineering, Inc., in the
amount of $4,177,100 for the design, installation, and commissioning of the Photovoltaic Canopy
System.
Adequate funds have been budgeted to provide for project management, inspection, labor
compliance, and miscellaneous administration costs.
ALTERNATIVE ACTIONS
Reject all proposals.
Other action as determined by the City Council.
FISCAL IMPACT
Project funds in the amount of $4,620,000 were approved by the City.Council in the Fiscal
Year 2009-10 Budget in Account F1016700-5161.001.
