A RESOLUTION OF THE LODI CITY COUNCIL AWARDING
THE SOLE -SOURCE BID FOR TWO UNITS OF PADMOUNT
LIQUID INSULATED VACUUM SWITCHGEARS
WHEREAS, Lodi Municipal Code §3.20.070 authorizes dispensing with bids for
purchases of supplies, services, or equipment when it is in the best interest of the City to
do so; and
WHEREAS, the 15kV padmount liquid insulated vacuum switchgears are utilized
throughout the underground distribution system in industrial, commercial, and residential
areas to supply branch feeders from the main feeders; and
WHEREAS, the two switches recommended for purchase here will be utilized in
the commercial areas developing north and south of Kettleman Lane and west of Lower
Sacramento Road; and
WHEREAS, these switches are a member of the same family of switches and
meet all the same conditions and requirements as the nine switches the City Council
approved as a sole -source purchase at the meeting of May 21, 2003. The configuration
of these switches is unique due to their proposed location. They will be used as a
switching point in the main supply lines to the developing areas from existing facilities;
however, when the new West Side substation is constructed west of this area the
switches will also be a key component for switching operations on supply lines from this
station as well as interconnecting switching points between stations. Switching points
are critical for the operation of electric systems for load balancing, clearances for work
on the system, troubleshooting, and timely service restorations; and
WHEREAS, the specification for this type of equipment requires a switch within
the equipment for each switch position that provides for a "visible open" point verifiable
through a viewing window. The main switch is a vacuum insulated switch and cannot be
visibly verified open. The equipment offered by Trayer Engineering does have this
feature. The "visible open" is a safety requirement when work is performed on the
system. Being able to obtain and verify such a visible open with a simple switch
operation is of great benefit. The alternative involves separating the 600 -ampere cable
connections requiring considerable amounts of labor and risking cable and terminator
damage and contamination resulting in possible future faults. The "visible open" is
required regularly during maintenance and construction/expansion work on the system.
The ability to obtain the "visible open" with a single switch operation offers significant
labor saving, preserves the integrity of the system and minimizes interruptions to our
customers; and
WHEREAS, the Trayer Engineering product is made of stainless steel resulting
in reduced maintenance costs; has over forty years proven experience in the utility
industry with 30 years in Lodi for the switch mechanism; and is insulated with a
biodegradable insulating fluid. Based on the above requirements and the fact that no
other manufacturer provides liquid insulated visible open switches, it is recommended
that the City Council authorize this purchase as a sole -source purchase; and
WHEREAS, based on the above information and the fact that the other
manufacturer has not changed design since the last bid and that Trayer Engineering
Corporation's quotation is less per unit than the unit price of the bid in January 2000, it is
recommended that the City Council authorize this purchase as a sole -source purchase;
and
WHEREAS, the City Manager recommends the sole -source purchase of two (2)
units of 15kV padmount liquid insulated vacuum switchgears from Trayer Engineering
Corporation, of San Francisco, CA, in the amount of $46,171.85.
NOW, THEREFORE, BE IT RESOLVED that the Lodi City Council does hereby
approve the sole -source purchase of two (2) units of 15kV padmount liquid insulated
vacuum switchgears from Trayer Engineering Corporation, of San Francisco, CA, in the
amount of $46,171.85.
