Re: Belt Line Road (East-West) Improvements from Denton Tap Road
to MacArthur Boulevard, Coppell, Texas.
Dear Mr. Ratliff:
We have prepared new estimates of the probable costs of
construction and engineering for this project. We have also
prepared Exhibits A - 1, A - 2, B -1, and B - 2, attached, which
indicate the allocation of costs between Coppell, Dallas, and
Crow - Billingsley.
Exhibit A - 1 shows the "Low" probable estimated construction
costs and allocation thereof based on the pricing of the low bid
received for the Denton Tap Road Improvements from Belt Line Road
to Sandy Lake Road plus 10% contingency. Exhibit B - 1 shows the
associated probable estimated costs and allocations of
Engineering Services for the project.
Exhibit A - 2 shows the "High" probable estimated construction
costs and allocation thereof based on the pricing of the median
bid received for the Denton Tap Road Improvements from Belt Line
Road to Sandy Lake Road plus 5% escalation and 10% contingency.
Exhibit B - 2 shows the associated probable estimated costs and
allocations of Engineering Se~ices for the project.
Since most Cities want a "cost not-to-exceed", exhibits A - 2 and
B - 2 were prepared in consideration of actual bids one to two
years from now, with no real indication available at this time as
to what the construction market will be.
The cost estimates referenced above have been made without the
benefit of any Preliminary Engineering Design or Surveying and
are based on the most current information available to Ginn, Inc.
Since Ginn, Inc. has no control over the cost of labor,
materials, equipment or services furnished by others, or over the
Contractor(s)' methods of determining prices, or over competitive
bidding or market conditions, Ginn, Inc.'s opinions of probable
Total Project Costs and Construction Costs provided for herein
are made on the basis of Ginn, Inc.'s experience and
qualifications and represent Ginn, Inc.'s best judgment as an
experienced and qualified professional engineer, familiar with
the construction industry; but Ginn, Inc. cannot and does not
guarantee that proposals, bids, or actual Total Project or
Construction Costs will not vary from opinions of probable cost
prepared by Ginn, Inc.

As you can see from the attached exhibits we have attempted to
provide estimates for the work activities which are related to
attending meetings; coordinating annexation/disannexation
proceedings; and working the various local, state, federal
agencies to accomplish a very complex project. Aside from the
cities of Coppell, Dallas, Irving, Dallas County and a private
developer, we must also work with FEMA, U.S. Army Corps of
Engineers, T.U. Electric Co., St. Louis and Southwestern Railway
Co., and Dallas Water Utilities just to get to the Preliminary
Design Phase of the project. Based on the foregoing we point out
that the numbers presented represent a Range of values in which
the work of this project may be accomplished.
Please call me if you have any questions.
Sincere ~
H. Wayne Ginn, P.E.
