Discussion:
On April 14, 2009, the City Council authorized the award of this contract to CT &F, Inc.
(CT &F). Under this contract, CT &F completed the construction task of second and third
phases of the Traffic Signal Modernization Project.
Construction of Phases 2 (Jamboree Road Corridor) and 3 (Airport Area) of the Traffic
Signal Modernization Project were combined to expedite deployment of the new traffic
signal system. The project included installation of fiber optic communications, 13 CCTV
cameras, and new traffic signal control equipment at 27 existing signalized intersections
along Jamboree Road and within the Airport Area. With the completion of phases 2 and

3 of the Traffic Signal Modernization Project, a total of 51 traffic signal and 15 Closed
Circuit Television Cameras (CCTV) are now online and can be managed from the Traffic

Department. A summary of the contract cost is as follows:

Total Project Change Orders
$50,279.47
The change orders were result of finding additional damage to traffic signal equipment
and conduit. Primarily, the change orders were related to in- ground damage or rotted
conduit.
Change Order 4 was significant at a cost of $20,742.08 and was related to two sections
of rotted conduit which could not be reused. At the two locations, Bristol Street South
between Campus Drive and Birch Street, and Jamboree Road at Ford Road, the
underground conduit had degraded to the point where new traffic signal interconnect
cable could not be installed in it. At these locations, new conduit was installed for a
combined length of 1223 feet, and the damaged conduit was abandoned.
Additionally, the Bristol Street South conduit replacement, as detailed above, also
caused significant time delay to the project. The large number of underground utilities

within the right -of -way forced staff to redesign the interconnect system, ultimately
locating the new conduit in the dirt shoulder along Bristol Street North. The time
needed to redesign the conduit run, along with the other change orders and extended
equipment delivery times and caused a delay in completion of the project of
approximately 59 days.
A summary of the project schedule is as follows:
