Construction of Phase 5 of the Traffic Signal Modernization Project included installation of
fiber optic communications, 3 Closed Circuit Television Cameras (CCTV) cameras, and
new traffic signal control equipment at 10 existing signalized intersections within the
Newport Center area. With the completion of the fifth phase, a total of 91 of the City -
operated 119 traffic signals and 27 CCTV cameras are now online and can be managed
from the Traffic Management Center at City Hall.
In addition to modernization of existing traffic signal locations, new traffic signals at
Newport Center Drive /Anacapa Drive and Newport Center Drive /Center Drive were
planned for installation as part of the project. The Newport Center Drive /Anacapa Drive
traffic signal was completed, while the Newport Center Drive /Center Drive intersection was
put on hold for completion of an Irvine Company project to add a fourth leg to the "T
intersection. Completion of this intersection is planned for Fall 2012 and will be
constructed by the Irvine Company through an encroachment permit issued by the City.
Due to aging traffic signal equipment within the Newport Center project area, the
2010/2011 Traffic Signal Rehabilitation CIP project was combined with the annual
modernization project. Through this program, the Newport Center Drive /San Miguel Drive
and Jamboree Road /San Joaquin Hills Road intersections were rehabilitated with new
equipment and wiring. The Newport Center Drive /San Miguel Drive intersection was
improved with the addition of left -turn signal phasing on the San Miguel Drive approaches.
This modification has proven to enhance traffic flow to and from Fashion Island.
The contract has now been completed to the satisfaction of the Public Works Department.
A summary of the contract cost is as follows:
Original bid amount: $ 508,372.50
Actual cost of bid items constructed: 456,932.50
Total change orders:
Final contract cost:
43,829.17

There were three change orders totaling $43,829.17. These change orders were the result
of changed conditions that were not apparent during design. The change orders were for
the following:

Total Project Change Orders
$ 43,829.17
Although the above change orders increased the cost approximately 8.6% over the original
bid amount, the total final project cost was $500,761.67, our approximately 1.5% below the
original bid cost. This reduction of the final cost is primarily a result of a credit received for
the deletion of planned work at the Newport Center Drive /Center Drive traffic signal
installation. Details regarding this change are below.
Completion of the project was delayed by 90 days do to three unforeseen significant
changes.
o Newport Center Drive /Center Drive Traffic Signal Installation — during installation of
the traffic signal, the Irvine Company requested a project to install a fourth leg to
the "T intersection. Prior to notification of proposed Irvine Company project,
Select Electric had already completed approximately sixty -five percent of the traffic
signal installation. As approximately thirty -five percent of the intersection
construction was not completed, a credit was given to the City.
o San Joaquin Hills Road Traffic Signal Interconnect Relocation — During review of
preliminary plans for a future widening project of the MacArthur Blvd /San Joaquin
Hills Road intersection by The Irvine Company, staff realized the existing traffic
signal interconnect conduit/line was located within the future widening. To facilitate
the future project, the conduit was relocated after additional design work and
explorative work.
o Newport Center Drive /Anacapa Drive — Unforeseen issues with newly installed
traffic signal equipment were rectified by extensive coordination with Southern
California Edison and the adjacent business owners. This work led to a redesign
of the traffic signal and relocation of the traffic signal controller cabinet.
