Denton Tap Road Improvements from Sandy Lake Road to Denton
Creek, Coppell, Texas.
Dear Mr. Allen:
At the request of the city Engineer, Mr. Russell Doyle, I am
writing this letter to inform you that Change Order No. 2 for the
subject project, covering the additional median openings and left
turn lanes requested by Univest Development and ABQ Development
were not approved by the Contractor, and therefore was not
considered for approval by the city Council at their February 28,
1989 meeting. A copy of the Contractor's February 27, 1989
letter is attached for your reference.
After reviewing both the Contractor's request for revision of the
Change Order, and his Contract with the city of Coppell, we have
determined that he is within his rights under the Contract to
request pricing other than the Contract Unit Prices for work
added to the Contract. The basis of his claim is that this is
new work being added to the scope of work of the Contract, as
opposed to an error in estimated quantities, which would have
been covered by the existing Contract Unit Prices provided the
error did not constitute more than a 20% deviance in the bid
quantities for a major item. We have also determined that his
proposed price for the "hand work" is reasonable for this type of
work.
In fairness to all parties concerned, we have revised proposed
Change Order No. 2 to allow the Contractor to perform the
required "hand work" placements of 8"-3000 psi reinforced
concrete for the subject median openings and left turn lanes at
the new unit price of $ 16.68 per Square Yard, as measured in
place. Any of the concrete placements for the subject median
openings and left turn lanes which are done by slip-form methods
will be paid for at the existing Contract Unit Price of $ 13.68
per Square Yard.
The total costs shown in the attached Cost Estimates and Summary
and Distribution of Construction Costs are based on the $ 16.68
per S.Y. unit price. However, since the Contractor may use slip-
form methods to place a substantial amount of the concrete
required for the subject median openings and left turn lanes, the
final costs may be somewhat lower than those shown.
17103 Preston Road · Suite 100 · LB 118 · Dallas, Texas 75248 · Phone 214/248-4900
It is our intention to have this Change Order no. 2 placed on the
April 11, 1989 city Council Agenda for their approval. If you
have any questions, please contact Mr. Doyle at (214) 462-0022.
Sincerely,
John C. Karlsruher, P.E.
Project Engineer
