Re: DeForest Road/Warren Court
Dear Mr. Goram:
Per your request, we have attached copies of all relevant
correspondence and plans regarding the above referenced subjects.
In regards to the DeForest Road Paving Improvements, many options
have been discussed in the past. Each option is described in the
attached correspondence. The options and their associated
estimated costs at that time were:
1. Triland Development Co. construct the improvements - no City
cost
2. Dallas Co. contract with the City to construct the
improvements - $37,500.00
3.. City's DeForest Road Waterline Contractor construct -
$27,750.00
4. Publicly bid the project - $55,000.00
At this time, 'Ginn, Inc. can prepare plans and specifications on
an hourly basis for a fee not to exceed $15,000.00. The
estimated construction cost to do a 2" asphalt overlay will still
be approximately $50,000.00 (based on a unit price of $40.00 -
$45.00 per ton of asphalt). Thus, total present project cost
would be $65,000.00 (this would include Warrent Court).
In regards to Warren Court, Albert H. Halff & Associates were the
engineers on the Lakes of Coppell project for Triland Development
ComDany. A cody of their Dian is attached. ApDarently,
easements currently exist which would permit a cul-de-sac to be
constructed. A 25' radius appears to be necessary to stay within
these easements, however. For a 50' diameter cul-de-sac and the
cross-section shown, we would estimate the costs for this cul-de-
sac to be as follows:
17103 Prcston Road · Suite 100 · LB 118 · Dallas, Texas 75248 · Phone 214/248-4900
2" HMAC 11 TONS @ $40.00/TON = $440.00
6" Flex Base 17 CY @ $35.00/CY = $595.00
Sub-total $1,035.00
Add 20% Contingencies (approx.) 215.00
Estimated Total = $1,250.00
By copy of this memo to Russell DoYle, P.E., we are transmitting
the requested costs for PS & E.
Please call if you have any questions.
