City Engineer Gus Psihoyos is recommending acceptance of the construction contract
for the 18th & Heeb Street Retaining Wall Slope Stabilization Project, as completed by
Drew Cook & Sons Excavating, Inc., in the final contract amount of $91,230.28, which is
a 23.3% increase from the original contract amount of $73,985.00.
The additional contract cost was primarily due to an increase in quantity for the stone fill
material ($7,500), additional clean stone ($3,200) and specialized concrete sawing
equipment ($2,100).
I concur with the recommendation and respectfully request Mayor and City Council
approval.

INTRODUCTION

2007 • 2012 •2013
The enclosed resolution provides for the acceptance of the construction contract for the
18th & Heeb Street Retaining Wall Slope Stabilization Project.
BACKGROUND
After evaluating several repair alternatives, the City Council authorized the staff to
proceed with the acquisition of 20 West 18th Street which allowed for stabilizing the wall
and slope rather than reconstructing the stone retaining wall along Heeb Street.
The 18th & Heeb Street Retaining Wall Slope Stabilization Project was authorized by
City Council as an emergency repair project.
DISCUSSION
The slope stabilization project included stabilizing the 18th/Heeb retaining wall by
constructing an engineered fill support buttress slope, remove the 18th St. stairs,
complete street repairs and miscellaneous related work.
The 18th & Heeb Street Retaining Wall Slope Stabilization construction contract was
completed by Drew Cook & Sons Excavating, Inc. of Dubuque, Iowa, in the final
contract amount of $91,230.28, which is a 23.3% increase from the original contract
amount of $73,985.00.
The additional contract cost was primarily due to an increase in quantity for the stone fill
material ($7,500) that was used to construct the buttress embankment slope, additional
clean stone ($3,200) that was placed as drainage material behind the original stone
wall, and specialized concrete sawing equipment ($2,100) that was used to safely
remove the lower section of suspended concrete stairs.
RECOMMENDATION
I recommend that the City Council accept the public improvements, establish the final
project contract amount in the amount of $91,230.28 and authorize final payment to the
contractor.
