INTRODUCTION
The enclosed resolutions authorize the award of the construction contract for the Heeb
Street Retaining Wall Reconstruction Project.
BACKGROUND
The Heeb Street Retaining Wall is located at the intersection of Kaufmann Avenue and
Heeb Street. This is an existing City-owned limestone retaining wall that is showing
signs of distress (existing stones have broken loose from the wall). The wall height
varies from 7 feet to 11 feet, with a wall length of 75 feet. The wall supports Heeb Street
(a 20-foot wide street) and has an 8-inch sanitary sewer main and 4-inch watermain in
close proximity.
DISCUSSION
The project base bid includes the wall reconstruction with native Dubuque limestone,
with geofoam as a backfill material. In order to reconstruct the retaining wall, most of
the street will be removed to accommodate the backfill. The street pavement will be 5-
inch asphalt to match the existing width of 20 feet. This reconstruction would be similar
to the retaining walls at Grove Terrace and St. Mary's Street. An alternate bid was also
considered for the use of integral, limestone-buff colored concrete wall that would
simulate the look of native limestone.
BID RESULTS
Sealed bids were received on the project on September 24, 2009. Drew Cook & Sons
Excavating, Inc. of Dubuque, Iowa, submitted the low base bid in the amount of
$98,567.00. This amount is 27.1 % under the engineer's estimate of probable cost.
