BID SPECIFICATIONS

CITY OF REDDING, CALIFORNIA

I. INTRODUCTION
The City of Redding is requesting bids to provide generator service, load testing, and on-call
maintenance for backup standby generators. In order for the Contractor to be considered qualified,
the company must possess technical competency in the servicing and load testing of large utility
backup generator sets (see Section IV Required Information), and have a service center that is located
within a 30-mile radius of the City of Redding. These generators are emergency backup generators
for critical facilities in the City of Redding; therefore, a quick response for requested service is
mandatory.
II. BACKGROUND
The City of Redding's emergency power generators will be serviced at various City locations; see
Attachment 1, Emergency Power Generator List, for all generator specifications and locations.
III. SCOPE OF SERVICES
The attached list (Attachment 1) indicates when the generator is to be serviced and/or load tested
(annually or bi-annually). Additional repairs needed throughout the contract period will be handled
on a time and materials basis. No individual service/work order will exceed $7,500.00 (labor and
material combined) without prior approval of the Purchasing Officer. The City reserves the right to
put out for competitive quote services which are expected to exceed more than $7,500.00.
A telephone number shall be furnished to the City for use when requesting repair service. This
number shall be promptly answered at all times during normal working hours by a person who will
timely dispatch needed service personnel. The contractor must also have in place an after-hours
emergency service phone number for emergency service requests requiring attention after normal
working hours. Electronic methods for answering telephone calls will not satisfy these
requirements. Failure to have a satisfactory answering service, promptly responding to after-hours
or emergency calls within two hours of requesting service, or failing to complete City work timely
shall be cause for cancellation of the contract.

5. Remove and replace fuel filters.

6. Fill engine with new lubrication oil.
7. Remove and replace air filters.
8. A three-part test to include testing oil, coolant and diesel fuel to confirm they are still in
operational condition will be required as part of the annual maintenance for each generator as
follows:
* The fuel Level 1 testing must be tested for particle count 11171, with microscopic
image to verify no issues with existing fuel
* The coolant must be Level 1 test for pH, Glycol level, freeze point, boil point,
conductivity, color and the presence of oil.
* The oil must be tested for true kinematic viscosity, oil condition analysis for soot,
oxidation, nitration and sulfur; to evaluate for contaminants such as water, fuel and
glycol, heavy metal analysis; hydraulic and filtered transmission compartments
receive particle count and microscopic image if required to verify there is not
excessive engine breakdown forthcoming.
9. Start engine to ensure proper operation after repairs are complete.
10. All fluids/waste oils must be removed from the site and become property of the Consultant.
All used fluids shall be properly and lawfully disposed.
11. Provide City with results of testing, inspection and recommendation of any needed repairs in
the form of a Service Report. Service Reports are to be provided within 30 days from date of
service or sooner if critical issues are found which may impact City maintenance or operations.

14. Check for leaks, connections, components, abnormal operating conditions;
15. Disconnect load testing equipment and remove from site;
16. Provide City with results of test (within 30 days from date of service or sooner if determined to
be critical to City maintenance or operations).

Contractor shall supply the City of Redding a service report for each generator serviced and/or load
tested. The service report shall include any recommended parts, repairs, or service required for
proper operation. In addition to the service report, if repairs are needed, a quote for the repairs shall
be included (see Sections VI and VII for pricing and mark-up information). These recommendations
may or may not be utilized by this contract. The City reserves the right to make any of the
recommended service repairs with its own maintenance forces. The City reserves the right to solicit
quotes from other vendors for recommended repairs if deemed to be in the City's best interest.
Once the generator has been repaired, the City of Redding may request the Contractor to re-test the
generator which will be billed according to the submitted Bid Form. The Contractor shall provide
the City with the new test results.
