The plans for street improvements on Norton A.F.B.
directed that a service line for the irrigation system be
connected to an existing water main along the west side of
Tippecanoe Avenue. However, during construction it was dis-
covered that there was no main in this area. A service
connection was made to an existing water main, in "A" Street,
about 200 feet east of Tippecanoe Avenue, and a 4-inch PVC water
line installed to serve the irrigation system installed by this
project. Installation of the service connection was done for the
negotiated price of $ 5 ,500 .00 , and the 4-inch pipeline was done
on a time and materials basis, since the extent of the work was
indeterminate. The total additional cost for this item of work
is $11 , 832 . 25 .
After the sidewalk along the east side of Tippecanoe
Avenue was constructed, it was found that the elevation was about
3 feet below the elevation of the ground in the vicinity of the
flagpole. A retaining wall was previously constructed by change
order to support the flagpole. After the retaining wall was
built, it was determined that a rail was needed to provide a
warning of the differential in elevation. A hand rail was in-
stalled by the Contractor on a time and materials basis.
The curbs and gutters that were installed, at the
southeast corner of Mill Street and Tippecanoe Avenue by the
project had to be removed and replaced, in order for the street
to drain properly. The new curbs and gutters were installed at a
higher elevation, as required to achieve adequate drainage. The
traffic signal poles and controller had previously been installed
by the Contractor at the grade shown on the contract plans, which
placed them below the grade of the replaced curbs and gutters.
These poles and controllers were necessarily raised to match the
new curbs and gutters. The Contractor performed this work on a
time and materials basis.
IVDA staff requested that additional signage, such as "NO
PARKING" and "NO ENTRY, " be installed. The Contractor performed
this extra work for a negotiated price.
It was determined during construction that additional
traffic signal inductive loops were needed, in order for the
three signals installed by this project to operate at optimum
efficiency. The Contractor performed this extra work on a time
and materials basis.
A buried tree stump was found to be in conflict with in-
stallation of a 4-inch irrigation line, and had to be removed.
Electrical service to the street lights on Del Rosa Drive, from
Third Street to the security gate, was disrupted by the
Contractor' s work. The plans did not direct the Contractor to
restore service to these lights. IVDA requested that the Con-
tractor perform the necessary work to restore service to these

lights . The recommendation was made that conduit be installed in
Del Rosa Drive, from Harry Sheppard Boulevard to Third Street, in
order to allow these traffic signals to be interconnected. The
Contractor performed these items of work on a time and materials
basis.
After the public sidewalks along Tippecanoe Avenue Harry
Sheppard Boulevard and Del Rosa Drive were installed, it was
found that some of the on--site sidewalks, leading to adjoining
buildings, were not accessible. The sections of existing
sidewalk, not in conformance with the new improvements , were
removed and replaced as required to provide handicap access. The
Contractor performed this extra work on a time and materials
basis .
The total additional cost for Change Order No. 14 is
$46 , 620 . 28 , which will increase the contract price from
$4 , 974 , 327 . 51 to $5 , 020 , 947 . 79 .
The total estimated project cost included an amount of
$845 , 687 . 00 for contingencies. The total accumulative cost for
Contract Change Orders No. 1 through 13 is $859 , 474 . 60 . Approval
of Change Order No. 14 will increase this amount by $46 ,620 .28 to
$906 , 094 . 88 .
Even though the line item for contingencies has now been
exceeded, the project is well within the amount approved in the
grant. The Economic Development Administration will allow funds
to be transferred between like items.
All costs incurred for this change order will be charged
to Account No. 242-362-5504-1993 . Funds to finance the addition-
al cost for Change Order No. 14 will be provided from the
following sources:
Federal Economic Development Administration Grant - 75%
Inland Valley Development Agency -- - - - - - - - - 250
140 City funds will be used to finance the cost of this extra
work.

Federal Project No. 07-49-02680
Contract Change Order No. 14
Justification:
(1) In order to provide adequate water flow for the landscaping
improvements on Tippecanoe Avenue it was necessary to install
a hot tap into an existing 10-inch water main and increase the
irrigation line from 2 to 4-inches in size.
(2) When the grading was performed on Tippecanoe Avenue, it was
realized that an existing Flag Pole was at the edge and 3-feet
above the elevation of the new sidewalk. A wall was placed
around the flag pole, additionally, a handrail needed to be
placed at the top of the wall due to the height differential
between the top of wall and the sidewalk.
(3) The elevation indicated on the plans for the installation of
the Traffic Signal Pole and controller, located on the
southeast corner of Tippecanoe Avenue and Mill Street was in
error. To correct this problem the new facilities at that
corner had to be raised from 6 to 8 inches.
(4) The plans did not provide for adequate traffic signage on the
project, after the street improvements and traffic striping was
completed, a problem with the traffic signage was identified
and additional signage was needed.
(5) The plans did not provide for adequate traffic signal loops on
the project and additional traffic signal loops were needed in
order for the traffic signalization to perform properly.
(6) An existing tree stub was removed so that the 4-inch hot tap
could be installed on "All Street. Additionally, in order to
reconnect the existing entry lighting system at the entrance on
Del Rosa, the contractor needed to install additional pull
boxes, conduit and wiring.
(7) After the improvements were completed, the contractor had to
regrade and pour additional concrete throughout the project to
tie the new sidewalk into the existing improvements on the
adjacent properties throughout the project.
