SUBJECT: Award of the Port of Dubuque Storm Sewer Improvements - Phase IV
Project
(CIP 410401: Port of Dubuque Storm Sewer Improvements - Phase IV)
INTRODUCTION
The enclosed resolution provides for the award of the Port of Dubuque Storm Sewer
Improvements - Phase IV Project.
DISCUSSION
The Port of Dubuque Storm Sewer Improvements - Phase IV Project involves the
construction of an 8-foot wide by 6-foot high box culvert from the junction box north of
the Portside Building, east and south to the Ice Harbor. Following the completion of
Phase IV, the Port of Dubuque collector storm sewer will be complete from the Ice
Harbor to Pine Street and the Star Brewery. Additional storm sewer will be required
west of Bell Street and north of 5th Street when it develops.
To install the storm sewer, the contractor must excavate through the edge of the
petroleum plume limits, As a result, a portion of the excavated soil will be delivered to
the Dubuque Metro Landfill. Testing revealed that the contamination is below the
threshold that would require special attention by the landfill. The landfill can use the soil
as cover or fill material. Therefore, the cost to deposit the soil will be the $30.78 per ton
fee established for rubbish. Following project initiation, Engineering determined that it
would be in the best interest of the City to pay the landfill fees outside of the
Contractor's contract. The Contractor would be paid to haul the material only. Based on
the testing done by engineering consultants Terracon and Preston Engineering, the
estimated amount to be deposited at the landfill is 1,394 tons,
Sealed bids were received on August 26, 2004. Tschiggfrie Excavating Co. of
Dubuque, Iowa, submitted the low bid in the amount of $217,100.85. This amount is
5,5% over the engineer's estimate. A summary of the bids received is as follows:
