TO: THE CITY COUNCIL COUNCIL MEETING DATE NO
FROM: THE CITY MANAGER'S OFFICE ( AUGUST 2. 1989 -
SUBJECT:
SPECIFICATIONS FOR THE PURCHASE OF WOOD UTILITY POLIS
RECOMMENDED ACTION: That the City Council approve the specifications
for the purchase of, and authorize advertisement for bids for, a total
of 89 wood utility poles, Classes H-1 through 3.
The bid opening date has been set for Tuesday, August 22, 1989.
BACKGROUND INFOMATION: The Electric Uti lity Department has requested
that fifty-six poles be purchased to construct three new 60KV overhead
lines connecting the new Industrial Substation to the current system.
The other thirty-three poles would be placed in inventory to support
the Utility Department's program of replacing damaged or deteriorating
poles currently in service.
The detail of pole lengths and classes is shown on attachment 1.
Estimated cost of this purchase is $115,000. The amount required to
support the 60KV line construction, about $100,000, is within the scope
of the overall funding for the Industrial Substation project. The
balance cf the cost, 615,000, represents about one-fourth of the
recommended 1989190 Overhead System Maintenance equipment budget.
Delivery is estimated to be about 12 weeks after placement of order.
Two critical factors are affecting the market for wood poles, pushing
prices on longer lengths up as much as 10% over the past 2-3 months.
First, exports to Japan are extremely strong. Second, environmental
issues concerning the spotted owl have taken nearly two and a half
million board feet of timber off the market, primarily in old growth
forests where longer poles are harves ced. Consequently, shortages are
beginning to occur i n some lengths and classes, with prices and lead
times tending to push upward.
