approve revised ins, and authorize the advertisement for bids for 20,000

MEETMIG DATE: June 21, 2006
PPA RM BY: Electric UWky Director
RECOMMENOW ACTION: That the City Council adapt a resolution rejecting the sde bid for
15,000 feet of #110 600V triplex, stud by G E Supply Co. of
North HWdands, Celdiornia. It is further recommoerrded that the
City Council approve revised sptions, and authorize the advertisement for bids for 20,000 feet of
#110 606V umlwgr+ound tnplsx use the revised specifications.
BACK4 ROUND IIFORMAIM: On April 5,20W the City Council approved specifications and
authorized advertisement for bids for 15,000 feet of this conductor.
One bid was received, and opened on June 6. 2006. The sole bidder, G E Supply Company of North
Highlartds ($27,880.31) Hook exception to several spec tions, including one that requires the
manufacturer to test the cable in accordance with industry standards, and to replace any defective cable.
G E Supply also required that an order for the conductor be placed by Tuesday, June 20.
Staff c ontacled other potential bidders to determine why they hadn't submitted proposals; three reasons
emerged. Respondents indicated that our requested quantity of 15,000 feet was below the minimum
amount most manufacturers will scale for production; that the type of #1/0 conductor we specified
('full neutral) was no longer considered a common type, and because of the volatility in the metals
markets bidders were relucMint to bid the fixed price that we require.
Therefore, in addition to recommending rejection of the sole bid, staff also recommends the approval of
specifioations revising the type of #110 600V triplex from "Full neutral" to the more common "reduced
neutral", and authorize the advertisement for bids for 20,000 feet of #1 f0 600V reduced -neutral triplex.
Delivery of this conductor is expected in early 2007, and is projected to cover calendar year 2007
requirements.
FISCAL IMPACT: Estimated cost of this purchase: $33,000
Materiel costs recovered by future sales of electrical power.
