HomeMy WebLinkAboutItem 10 - City Wide Traffic Signal Light ProjectCity Wide Traffic Signal Light Emitting Diode (LED) Retrofit Project Contract Award
Republic Electric
Therefore, the City issued an RFP instead of a typical low -bid contract. An RFP allows
staff to evaluate each proposal based on a set of criteria. These criteria include prior
experience, qualifications of personnel, equipment quality and price. Each criteria is
given a point score and the proposal that receives the maximum points is selected.
The City received two proposals, one from Republic Electric and the other from Durable
Specialties. Based on staff evaluation, Republic Electric received the highest score (see
enclosed scoring sheet). Since a majority of the project includes state signals, staff
discussed the evaluation and selection process with TXDOT and received their
concurrence.
Staff recommends awarding the contract to Republic Electric.

an initial audit of existing lamps and locations and a
preliminary technical analysis to identify any
potential problems. The plan also called for
creating a prioritized list and providing the list of
locations to be worked on each week to City Staff.
The plan also included a task for a final inventory of
all retrofit locations.

to 20 points)
Republic Electric recently completed a city wide
LED retrofit for the City of Garland that included
approximately 200 traffic signals and a citywide
LED retrofit for the City of Austin that included
approximately 800 traffic signals. Both cities
indicated that they were satisfied with the
Contractor's performance.
Durable has also performed extensive traffic signal
work all over Texas, including for the City of
Grapevine. Staff has been satisfied with Durable's
work performance in the past. However, Durable
does not have any prior experience with large scale
city-wide LED retrofit projects. All the projects listed
as prior experience in their proposal involve traffic
signal construction but do not involve LED retrofit
work on a large scale.

The LED retrofit project includes supplying green

and yellow arrows, green, yellow and red circular
indications and pedestrian indications. Repubic
Electric's proposal included LeoTek's equipment
and Durable's proposal included equipment from
Dialight. Staff evaluated each vendor's equipment
thoroughly. Samples of each supplier's equipment
were obtained from the vendor and installed on the
field as part of the evaluation process. Both
vendors' equipment for green and yellow arrow
indications was rated equally. However, LeoTek's
red, yellow and green circular indications were
found to be superior compared to Dialight's
equipment. Dialight's LEDs have hundreds of small
LEDs that form the shape of a circular indication.
When a few LEDs fail, the signal indication still
functions but at a lower intensity. This also leaves
empty spaces at areas where the LEDs have failed.
LeoTek's design has four to five high intensity
LEDs that are placed at the center of the indication
and uniformly disperse light by means of a lens.
The advantage with this design is that if one or two
LEDs fail, the intensity loss is compensated by the
remaining LEDs thus preserving the intensity of the
indication and the uniform glow.
LeoTek's pedestrian indication meets the city's
specifications while Dialight's pedestrian indication
does not meet the city's specification.
The City has also used both manufacturer's
products in the past. Our experience with LeoTek
in terms of both quality and customer service has
been very good. On the other hand, we have had
several quality problems with Dialight's products.
The LEDs indications installed at Dove & Dove
Loop for example are Dialight's products and have
had several failures. Staff has had a tough time
getting the failed products replaced through the
vendor's distributor.
