SUBJECT: Port of Dubuque Watermain Extension Project
C I P: 7402261
DATE: October 5, 2012
Sealed bids were received for the Port of Dubuque Watermain Extension Project. City
Engineer Gus Psihoyos recommends award of the contract to the low bidder,
Tschiggfrie Excavating, Inc., in the amount of $160,310.40, which is 19.79% over the
estimate of probable cost. The higher than anticipated cost is due to the required
casing pipe that needs to be installed under the railroad tracks and contractor expense
of needing railroad liability insurance.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

tracks
