SUBJECT: Floodwall Levee Slope Stabiliza ontl'" Project (CIP #1002042)
DATE: October 9, 2009
INTRODUCTION
The purposes of this memorandum are to provide information and recommend a course
of action regarding the attached change order for the Floodwall Levee Slope
Stabilization Project (CIP #1002042).
BACKGROUND
$295,000 was budgeted in FY09 for this project. Bid proposals were solicited in
February and a contract awarded to the low bidder, Eastern Iowa Excavating and
Concrete LLC, that same month in the amount of $183,087.50. After retaining an
additional $14,032 for engineering costs and another $18,308.75 for contingency funds,
the remaining budgeted monies were transferred to our department's FY09 snow and
ice control operating budget to cover the deficit due to last winter's above average
snowfall. Actual project work was delayed by the Mississippi River's high water levels
this spring. As a result of those high water levels, the project's first change order
extended the project's completion date -but did not provide for monetary changes.
DISCUSSION
The attached change order (#2) does provide for additional funds ($41,530.41) to be
paid to the contractor. These funds are needed to cover the costs of the additional rip-
rap (+1,629.86sy), bedding stone (+40.31sy), and engineering fabric (+1,070sy)
required to repair a longer section of shoreline than originally planned and specified.
This larger repair project was due to the shoreline erosion being exacerbated by high
water events subsequent to the project's original design. Given the $183,087.50 bid
award amount plus the $18,308.75 contingency, the final contractor's cost to complete
the project of $224,617.91 equals an overage of $23,221.66. Also, the additional
engineering design and inspection needed to address the larger project exceeded the
original engineering allowance by $5,006.50. In total, the project, now completed,
exceeded its authorized award allowance of $215,428.25 by $28,228.16 -but still was
more than $50,000 under the original project appropriation of $295,000.
In recognition that almost $80,000 of the original $295,000 was transferred to the Public
Works Department's snow and ice control operating budget last winter, Street and
Sewer Maintenance Supervisor John Klostermann, by his attached memorandum, is
recommending that the total project overage of $28,228.16 be addressed through the
$44,723.02 unencumbered balance remaining in CIP #3501445 - Floodwall Post-Flood
Repairs.
ACTION STEP
concur with John's recommendation and request that you sign the attached copies (3)
of the project's second and final change order.

Capital Improvement Project #1002042
DATE: October 8, 2009
Introduction
Attached change order number 2 provides for a contract adjustment for measured
quantities related to the Floodwall Levee Slope Stabilization Project.
Discussion
Two change orders have been issued for the project. Change order number 1 changed
the completion date of the project from April 15, 2009 to June 1, 2009. This was
necessary due to high water this spring which delayed the start of the project.
Change order number 2 establishes the final construction contract price at $224,617.91.
The increased cost of the project is due to the differences between the original contract
quantities and the final installed quantities.
Budget Impact
A summary of the project is as follows:
Construction Contract $224,617.91
Engineering 19,038.50
Total $243,656.41
am proposing that the project be funded in the following way:
CIP No. Fund Description Amount
1002042 Floodwall Levee Slope Stabilization Project $215,428.25
3501445 Floodwall Post Flood Repair Project $ 28,228.16
$243,656.41
Action Requested
I am requesting that the City Manager sign the attached change order which establishes
the final construction contract price at $224,617.91.
