Denton Tap Road Improvements from Sandy Lake Road to Denton
Creek - Parkway Blvd. extension and additional Left Turn
Lanes and Median Openings requested by ABQ Development and
Univest Development.
Dear Mr. Doyle:
On the afternoon of Thursday, ~,arv 5.~ 19~J~, a meeting was held
in these offices between yourself, Mrs. Daneshmand, Mr. Wayne
Ginn, and myself to address the requests by ABQ Development and
Univest Development for additional left turn lanes and median
openings to be included in the Denton Tap Road project to serve
their properties. The minutes of this meeting are attached. The
end result of the meeting was the direction from yourself to
proceed with preparation of a Change Order to the Contract with
L. H. Lacy Co. to provide for the construction of the requested
facilities, contingent upon approval by the City Council. One of
the stipulations to be included for Council consideration is that
the financial commitments from ABQ and Univest to pay for these
additional improvements must be satisfied before the approved
Change Order can ~e issued and work commenced on the subject
items. ~ ~bd~/~~/%~/~ ~
Enclosed herewith, please find the tabulations of the estimated
construction costs for the subject items, and our suggested
distribution of these costs between ABQ and Univest.
Additionally we have included the Draft Agenda request for this
item and a copy of Change Order No. 2 which we are sending to the
Contractor for execution. Please note that the Change Order,~
itself ~ ~no~ include the additional costs of Engineerinq,~
Testing and Inspection, which typically run about 10% of the
es~ted cost of construction, and should be added to the
financial commitments require~--~om ABQ and Univest.
In your review of Change Order No. 2 and the draft agenda
request, please note that the Original Estimated Contract Amount
in the City Council's award of the Contract was $ 1,803,363.03.
This amount became the actual budget amount for the paving and
drainage improvements covered under the L. H. Lacy Co. Contract.
With some cost savings realized by the city through a Contractor
proposed price reduction (resulting from having been awarded both
Denton Tap projects) Change Orders and Field Changes, the current
estimated Contract Amount is $ 1,791,489.06, which technically is
$ 11,873.97 under budget. With the addition of the items
17103 Preston Road · Suite 100 · LB 118 · Dallas, Texas 75248 · Phone 214/248-4900
mentioned herein, the budget is technically exceeded by
$35,899.33. This budget variation and that associated with the
Engineering, Testing and Inspection budget will partially be
offset by the Developer financial commitments once they are
received. The reason that the budget offset is only partial is
that as per our meeting of January 5, 1989 the costs of the west
turnout of Parkway Blvd. ~~11 n~ be included in the financia_l
commitments. Of the Developer. As you will recall from our
discussion major intersections have customarily been treated as a
part of the overall project, benefiting the general public as a
whole, and not constructed solely for the use of one particular
user. Therefore, budget restoration for this item should come
from the contingency fund for the project, which to date is
~dequately in tact.
Although quite lengthy, I feel the above, with the attachments
will give you what you need to bring this item before the City
Council. If you need any clarifications, a follow-up briefing,
or additional information, please call me at your convenience.
Sincerely,
Johrf C. Karlsruher, P.E.
Project Engineer
