Construction of Phase 6 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 17 existing signalized intersections along the San Joaquin Hills Road and Newport Coast
Drive corridors. With the completion of the sixth phase, a total of 116 of the City- operated 122 traffic signals
and 35 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, the 2013/2014 Traffic Signal Rehabilitation
CIP project was combined with the annual modernization project. Through this program, aging equipment
at the following intersections was replaced:
• San Joaquin Hills Road /Crown Drive;
• San Joaquin Hills Road /Marguerite Avenue; and
• Newport Coast Drive /Coast Highway.
During the rehabilitation work, the San Joaquin Hills Road /Crown Drive intersection was improved with the
addition of left -turn signal phasing on the San Joaquin Hills Road approaches to facilitate left -turn
movements on to Crown Drive.
The contract is now complete to the satisfaction of the Public Works Department. A summary of the

The final overall construction cost was approximately 14.1% over the contract amount. The increase in
project expenditures was a result of contract change orders. Of the seven change orders required to
complete this project, the following three unforeseen events attributed to the majority of the change order
cost:
1. Damaged Traffic Signal Interconnect Conduit: This unforeseen condition required replacement of
approximately 1,600 feet of decayed and unusable underground conduit on San Joaquin Hills Road from
San Miguel Drive to Marguerite Avenue to facilitate the installation of Fiber Optic communication cable.
This change amounted to an unforeseen expenditure of approximately $65,550 to install new conduit,
pothole /explore for conflicting utilities, set new pull boxes and restore the sidewalk and roadway pavement.
2. Relocation of Edison Electrical Service: During construction, Southern California Edison required the
point of electrical service to be relocated from the existing location at the north side of the intersection to a
13 -2
new location on the south side of the intersection to accommodate the installation of the new traffic signal
control cabinet. This change amounted in an unforeseen expenditure of approximately $28,720 to install
new conduit, pothole /explore for conflicting utilities, set new pull boxes and restore the sidewalk and
roadway pavement.
3. Emergency Traffic Signal Outage Response: During the project, deteriorated underground wiring
caused a chain - reaction of traffic signal wiring and equipment failure at the San Joaquin Hills
Road /Marguerite Avenue intersection. This malfunction required an emergency response with a significant
amount of troubleshooting and equipment replacement. At the direction of City Staff, the Contractor
responded to the traffic signal outage to expedite the rewiring and troubleshooting of the traffic signal. Use
of the Contractor for this item helped to reduce the time required to repair the intersection and minimized
the impact to the community. This change amounted in an unforeseen expenditure of $14,807.14.
Due to the large magnitude of the above change orders, the original 10% contingency authorized by the
City Council was exceeded. Pursuant to Council Policy F -3, Staff requested an increase in allowable
contingency funds from 10% to 25 %.
The original contract allowed for 100 consecutive working days to complete the original scope of work. Due
to the magnitude of the above - mentioned change orders, construction was extended an additional 100
working days. The project was substantially completed on May 1, 2015.
A summary of the project schedule is as follows:
Estimated Completion Date per July 2014 Schedule: February 27, 2015
Project Awarded for Construction: May 13, 2014
Completion Date per Contract and Approved Extensions: May 1, 2015
Actual Substantial Construction Completion Date: May 1, 2015
The eighth and final phase of the Traffic Signal Modernization project is planned to begin construction in
the fall of 2015. Upon completion of the final phase in the summer of 2016, all 122 City- operated traffic
signals will be integrated into the City's traffic signal system and operational from the Traffic Management
Center located at the Civic Center.
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this project exempt from the California Environmental Quality Act
( "CEQA ") pursuant to Section 15304, Class 4, of the CEQA Guidelines, California Code of Regulations,
Title 14, Chapter 3, because this project involves minor alterations to the condition of the land and does not
involve removal of mature, scenic trees.
NOTICING:
The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at
which the City Council considers the item).
