CHANGE RDER NUMBER 2 - CHANGE IN STREET LIGHTS SYSTEMS
The cost of this Change Order is $2,337.00.
Under t e contract the City is to furnish the ornamental street light standards and
luminai es for Third Avenue, "F" Street to "G" Street and luminaire conversion for
Third A enue, "F" Street to "G" Street and luminaire conversion kits for the street
lights rom "E" Street to "F" Street.
The o n final design for street lights called for 100 watt 240 volt high pressure sodium
vapor 1 minaires with regulator ballasts. Subsequent to the award of contract, we
have re eived the latest San Diego Gas & Electric Company rate schedule which. provides
for a $ .02 per month reduction in the cost of energy for each 100 watt 120 volt high
pressur sodium vapor luminaire with a reactor ballast..
To take advantage of the rate reduction, we ordered the more efficient luminaires with
reacto ballasts. The cost of Change Order #2 is balanced by the savings from
purchasing the 120 volt luminaire with a reactor ballast and the reduction in energy
costs r the first year. The luminaire with reactor ballast is $20.67 cheaper for a
total s vings in material costs of $1,529.58. The savings in energy costs for using
the lu inaire with reactor ballast during the first year is $905,76, The table below

order #2 covers the cost of changing one of the "hot" conductors to a neutral
sling for the existing street lights from "E" to "F" Streets and increasing
of the conductors for the street lights from "F" to "G" so that they will
on 120 volts with the reactor ballasts.
CHANGE~ORDER NUMBER 3 - EXISTING MEDIAN ISLAND IRRIGATION SYSTEM
The colt of this change order is $1,852.
Community Development has completed an underground district within the Town Centre Focus
Area w st of Third Avenue between "F" Street and Madrona. Due to this work it has been
found hat the irrigation controllers for the Third Avenue median between "F" Street and
Madron Due to this work it has been found that the irrigation controllers for the
Third venue median between "F" Street and Madrona has been left without electrical power.
The it igation system is presently under manual control. The Parks and Recreation
Depar ent has requested Community Development to provide a new source of power to the
median island irrigation systems.
We hav requested a proposal from L. R. Hubbard Company to install electrical conductors
from t e control panel being installed on the south side of Madrona Street to the point
of con ection in the median island. We have received a quotation from L. R. Hubbard to
install an additional #14 gauge 6-conductor wire from the panel to the median island,
an app oximate distance of 600 lineal feet using 1-1/4" PUC conduit, pull boxes and the
necess ry other materials and labor.
The co t of $1,852 has been reviewed by our Traffic Engineering Division and recommended
for ap royal. We have reviewed this proposal with Community Development and they have
approv d the expenditure for this work from Bond Fund Account #995-9950-BF02.
