SUBJECT: 911 High Bluff Retaining Wall Repair Project
DATE: February 10, 2009
City Engineer Gus Psihoyos is recommending acceptance of the construction contract
for the 911 High Bluff Retaining Wall Repair Project, as completed by Arensdorf
Trucking & Excavating, Inc., in the final contract amount of $112,371.04. This cost was
$8,952.12 higher than anticipated due to the fact that an additional 10 feet of wall
needed repair to securely fasten it to either end of the existing retaining wall.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

SUBJECT: 911 High Bluff Retaining Wall Repair Project

DATE: February 9, 2009
INTRODUCTION
The enclosed resolution provides for the acceptance of the construction contract for the 911
High Bluff Retaining Wall Repair Project.
BACKGROUND
On October 13, 2008, the City Council authorized (Resolution 359-08) emergency repairs to a
retaining wall on private property behind 911 High Bluff and street pavement of Thomas Place.
This project was necessitated due to the impending collapse of the private retaining wall
endangering the private residence and also the nearby street pavement. The property owner
of 911 High Bluff was notified by the City that it was proceeding with the repair due to the
property owner's failure to complete the work in a timely manner.
Based on Iowa Code § 384.103 and § 364.12(3)(c), and through the competitive quotation
process for public improvements, this project was awarded on October 20, 2008 to Arensdorf
Trucking & Excavating, Inc. of Anamosa, Iowa, in the amount of $103,418.92.
DISCUSSION
The 911 High Bluff Retaining Wall Repair Project was completed by Arensdorf Trucking &
Excavating, Inc. of Anamosa, Iowa, in the final contract amount of $112,371.04.

The increased construction cost is based on the need to remove and repair an additional 10
feet of wall so that the wall repair is securely fastened to either end of the existing retaining
wall.
At a later Council meeting, the Engineering Department will request a public hearing to
approve an assessment for the property owner of 911 High Bluff Street.
RECOMMENDATION
I recommend that the City Council accept the improvements and authorize the payment of the
contract in the amount of $112,371.04 to Arensdorf Trucking & Excavating, Inc. for the 911
High Bluff Retaining Wall Repair Project.

2009, as part of the City's annual street program.
ACTION TO BE TAKEN
I respectfully request that the City Council adopt the attached resolution accepting the
improvements and authorizing payment of the contract in the amount of $112,371.04 to
Arensdorf Trucking & Excavating, Inc. for the 911 High Bluff Retaining Wall Repair Project.
