Re: Change Order No. 1 -- Moore Road
Dear Mr. Powell:
Enclosed please find Change Order No. 1 for the Moore Road
Improvements project. The items shown on attachment number
one of the Change Order reflect the revised quantities
required for the modifications described below for the bridge.
Execution of this Change Order will result in a reduction in
the contract price by $72,038.48, which results in a new
total contract amount of $1,866,313.47.
The purpose of this Change Order is to economize the cost of
the bridge without sacrificing the aesthetics the City of
Coppell is desiring. This is accomplished by utilizing a
standard Texas Highway Department (T.H.D.) bridge design and
modifying the superstructure by replacing the standard type
C-4 (aluminum) rail with a concrete barrier rail.
The original bridge selected by the City had a sub-structure
consisting of pier walls with cast-in-place T-beams and
girders. Results of the bidding showed that the proposed
T.H.D. bridge design which utilizes pier columns and Type C
prestressed concrete beams is more economical (see bid
tabulation enclosed).
We have reviewed this Change Order and recommend approval.
Sincerely,
Kevin Peiffer
