ProjectG
Background
In November 1991, the owners of their property at 4201 Page Mill
Road (near the intersection of page Mill Road and ~onte sello Read)
advised the City of their intention to significantly remodel the
house. The house will be much larger, and the planned electrical
use required conversion of the electrical service from single-phase
residential-type service to a larger three-phase commercial-type
service. Because onlY single-phase service was available at the
property I the single-phase system requires upgrading to t_hree
phase. This is accomplished by adding an additional conductor to
the system (two wires to three wires). Approximately 1700 feet of
additional wire is required.
A field investigation found that several of the ... ·000 power poles
involved wer-e severely decayed. This presents an unsafe. condition,
and installation of the additional ~ire is not possible without

replacement ot the decayed poles. This finding ~as confirmed by
revie'ii of the results from the 19~1 wocd pole testing progra1I'
conducted by Osmose wood preserving. A further investigation found
many of the 'Wood poles providing service to the customers atop
Black Kcu..'>ltain, along Monte Bello p.oad, to be in a similar severely
deteriorated state. CUstomers sen'oed by this lir.e include the
Federal Aviatio;1 A.dministration, Ford Aerospace, Hewlett-Packard,
santa Clara county Transit, city of Palo Alto Emergency servlc~s
Radio Remote and Heritage Cable T.V.
Several options were considered. Relocating a portion c·f the polllo°er
line to Paqe Mill Road, to eliminate sevpral sections with poor
accessibility, 'Was considered. but concerns expressed by t.he Mi'i
Peninsula Open Space District and property owners caused this
option to be abandoned. Undergrounding of sections or all of the
line was considered but rejected, due to the 5iqnificant costs
involved and the City's inability to recover any of these costs
from the small a~ount of power sales involved. Local residents,
Pacific Gas & Electric (co-occupant '"dth the city or. several
poles), and the Open Space District were met 'With and options
explored. The most economical and generally acceptable solution is
to replace the existing poles in their existing locations. The
rebuilt line should have a 30 year life, improve serJice
reliability to the customers in the Foothills, and lessen the fire
hazard from the deteriorated line.
staff decided to release this 'Work, pole replacement and "'ire
installation, to contract because of the heavy workload of City
overhead line crews in conjunction with the underq=ound conversion
projects and 4kv-to-12xV conversion ~ork in progress.
Specifications ancJ drawings for the work were developed and
released for competitive bids.
Bid EValuation
Fol1o~ing design completion, six contractors visited the job site.
Four bids were received. Dolstra Electric is the lowest bidde~ at
$52,839, as shown in the tabulation of bids attached. The
Engineerls estimate for this work is $69,600. Staff conducted
reference checks for the contractor and subcontractors and
responses were favorable.
Funding
Funds for this project are available in the Electric Fund CI~,
FY 92-93, OVerhead Extensions and Replacements Project.
