RE: Fairway Drive Project # ST 96-04
Dear Mr. Neblett:
This letter is written as a follow-up to the agreement approved by the City of Coppell on
October 14, 1997 concerning a cost sharing on the traffic signal at Fairway Drive/Belt Line
Road. At the time of the agreement, the estimated cost of a 'traffic signal was approximately
$85,000. Included with this letter is a copy of our final pay estimate from the contractor
with items pertaining to the traffic ~onal highlighted.
The total cost to the City of Coppert for the traffic signal was $125,135.10. This includes the
following:
Items 18-23/Street markings
Items 29-33/Conduits
Items 34-41/Wiring
Item 42/Opticon
Item 43/Railroad interconnect wiring
Item 44-45/Loop detector and hardware
Item 46/Controller
Items 47-49/Foundations
Items 50-~2/Signal poles and Mask arms
Items 53-55/Signal heads and backphtes
Items 56-57/Pedestrian assemblies
Items 58/Electric Service
Items 59 & 60fPuH boxes
Item 61/Display board
Items 62-65/Traffic sign poles/foundations
Items 66-69frraffic signs
Item 70/Street name

It is my opinion that the cost of the traffic signal exceeded estimates became it was part of a
street project and the traffic signal contractor was a subcontractor to the street paving
contractor. We awarded a project in January 1999 for a very similar traffic signal along
Denton Tap Road at a total cost of $97,300. That was a stand-alone project of which the
low bidder was a contractor who speelali74~s only in the illstallation of ll'af~c sig!lals.
To try to be as fair as possible and to stay somewhat dose to the estimated $85,000, I have
reevaluated the bid items and am prepared to base your 1/3 cost share on a total value of
$92,049.30. This nnmber is comprised of the following:
Items 29-33/Condnits
Items 34-41/Wiring
Item 46/Controller
Items 47-49/Foundations
Items 50-52/Signal poles and mast arms
Items 53-55/Signal heads and backplates
Item 58/Electric service
Total
$20,306.90
14,230.40
24,000.00
6,392.00
14,200.00
10,920.00
2.000.00
$92,049.30
AH of these components would not constitute a completed traffic signal installation since it
does not include items such as marking, loop detectors, traffic signage, etc. However, they
do constitute the bulk of the items necessary for the construction of a traffic signal. Your
cost share of the $92,049.30 would be $30,683.10.
In order for the City to final out this project please remit a check in the amount of
$30,683.10 in accordance with paragraph 2 of the Traffic Signali~,ation Cost Sharing
Agreement. I hope that you agree that my analySiS Of the COStiUg is fair, however, if you
should have any questions please feel free to contact me at your convenience.
Sincerely,
Kenneth M. Griff'm, P.E.
