Michael C. Van Milligen, City Manager
FROM:
SUBJECT:
Michael A. Koch, Public Works Director
Mississippi Riverwalk Phase I
River's Edge Plaza and Alternate Component
INTRODUCTION
The enclosed resolutions provide for the acceptance of the construction contract for the
Mississippi Riverwalk Phase I, River's Edge Plaza and Alternate Component Projects.
BACKGROUND
The Mississippi Riverwalk Phase I, River's Edge Plaza and Alternate Component was the
first completed component of the $188 million dollar America's River Project.
The River's Edge Plaza Project provided for the construction of a 15,000 square foot plaza
facility, landscaping features and related amenities at the Delta Queen and Mississippi
Queen landing area location outside the floodwall at the Port of Dubuque. The 5,000
square foot main plaza area is decorative buff colored concrete with a stamped slate
texture surface with decorative quarry red slate texture accent banding and quarry red
slate texture cascading concrete stairs, which extend downward to the edge of the
Mississippi River. The project amenities include decorative railings, benches, ornamental
lights, bike racks, trash receptacles, and landscaping.
The alternate phase of the project is located between the floodwall and the Welcome
Center building. The alternate included constructing a small plaza area adjacent to the
floodwall and constructing new decorative concrete sidewalk from the plaza area to the
Welcome Center.
DISCUSSION
The River's Edge Plaza and Alternate Component has been completed by Renaissance
Construction of Dubuque, Iowa, in the final contract amount of $767,761.20, which is a
28% increase from the original contract in the amount of $599,638.00.
As summarized in previous correspondence (copies of which are attached), project costs
increased partially as a result of increased quantities for "as built" unit price items of
construction. Additionally, staff was directed to incorporate the quarry red surface
hardener to the accent banding and cascading stairs, incorporate the cut limestone surface
texture to the concrete retaining wall, and install additional conduit and pedestals for future
telecommunications and power outlet applications. The following is a partial breakdown of
the approved change orders to the River's Edge Plaza project.
Cascading Stairs, Perimeter Foundation Walls: $ 17,600
Reinforcing Steel, Epoxy Coated Upgrade $ 14,500
Construction Quantities Adjustment: $ 50,000
Colored Concrete Surface Hardener: $ 16,300
Limestone Surface Texture, Retaining Wall: $ 15,700
Telecommunications/Power Conduit & Pedestals: $ 10,800
Electric Service Upgrade, 200 Amp: $ 5,200
Pavilion, Foundation Footings: $ 5,300
Ramp, Aluminum Diamond Plate Upgrade: $ 4,600
Approved Change Orders Sub-Total: $140,000
RECOMMENDATION
I recommend that the City Council accept the improvements and recommend that the final
contract amount be established at $767,761.20 for the Mississippi Riverwalk Phase I,
River's Edge Plaza and Alternate Component Projects.
PROJECT FUNDING
The project cost summary for the Mississippi Riverwalk Phase I, River's Edge Plaza and
Alternate Component Projects are as follows:
River's Edge Plaza
Alternate Component
Contingency (15%)
Total Project Cost
Estimate Bid Final
$393,844.00 $478,349.50 $654,917.55
73,439.00 121,288.50 112,843.65
59,076.00 59,076.00 0
$526,359.00 $658,714.00 $767,761.20
The project funding for the Mississippi Riverwalk Phase I, River's Edge Plaza and
Alternate Component Projects are as follows:
Bid Final
General Fund $486,195.00 $767,761.20
Private Sources 51,231.00 0
Total Project Funding
$537,426.00 $767,761.20
Sealed bids on this project were received in September, 1999 in the amount of
$478,349.50 plus a contingency allowance of $59,077, for a total budget of $537,426.
The overage of $126,092 based on the bid and contingency required, was reduced from
the overall Riverwalk project contingency.
A change order was issued in February 2000 to correct concrete quantities from the
original bid documents at a cost impact of $39,734. This change left a contingency
balance of $19,342.
Another change taken to City Council in February 2000 included changing the concrete
surface to the full depth red colored concrete, shake hardener and stamped slate texture.
The additional cost associated with this change was $21,000. This change order used the
balance of contingency funds and put the project slightly over budget.
in April, 2001, a bid alternate of $121,288 for the landside nautilus plaza and sidewalk
along the harbor between the Pot[side Building and River's Edge Plaza was honored by
the contractor at the original unit bid price and was added to the River's Edge Plaza
contract. This increased the budget for the River's Edge Plaza to $658,714.The bid
alternate amount was taken from the funding for Phase II of the Riverwalk, since that is
where this component had originally been budgeted.
When the decision was made to move the pavilion from the landside nautilus to the River's
Edge Plaza, footings ($5,300) and electrical conduit and service ($10,800) were required
to be added to the Phase I budget, but again reduced from the cost for Phase II. The
limestone texture was added to the retaining wall at a cost of $15,700. Other change
orders explained further in the memo from City Engineer Mike Koch added another
$77,247 to the project cost. These additional costs were reduced from the Riverwalk
Contingency, which was replenished as cost estimates for Phase II were finalized and the
City went through the FY 2002 through FY 2003 ClP process.
ACTION TO BE TAKEN
The City Council is requested tO adopt the attached resolutions accepting the improvement
and establishing the final contract amount for the Mississippi Riverwalk Phase I, River's
Edge Plaza and Alternate Component Projects.

SUBJECT: River's Edge Plaza Project Construction Alternative
The purpose of this correspondence is to update you on the status of the River's Edge Plaza
project, and obtain direction on the request to proceed with the alternate component of the project.
Steve Boge, of Renaissance Construction, has requested that the City authorize his company to
proceed with the alternate bid component, and has a~:eed to honor his bid unit prices. To briefly
summarize, sealed bids were received on the River's Edge Plaza project on September 14, 1999.
The following is a summary of the bids received:
Base Bid
Base Bid Alternate with Alternate
Renaissance Construction
Portzen Construction
Tschiggfrie Excavating
$478,349.50
$617,457.90
$770,637.35

$110,978.25
$140,064.65
$599,638.00
$728,436.15
$910,702.00
The construction contract was awarded to Renaissance Construction for the base bid component
only. The alternate phase of the project was not awarded due to uncertainty with the new casino
owners and ~hotel development.
The alternate phase of the project is located between the floodwall and the Welcome Center
building. The alternate includes the removal of the existing sidewalk, constructing .a small plaza
area adjacent to the floodwall, constructing new sidewalk from the plaza area to the Welcome
Center and the installation of three (3) ornamental light fixtures. The esthetic appearance of the
alternate components Will match those of the base bid (River's Edge Plaza), including buff
colored field areas, quarry red accent banding and a stamped slate texture surface.
In reviewing the bids received in September 1999, Renaissance was low on the base bid and the
overall 'bid (base,-plus alternate), however, when you look at the alternate bids separately,
Renaissance was not [ow1 Giving consideration ti) the overall low bid, and the co,remitment of
Renaissance to honor there bid unit prices, which are 1-'½ 'y~ars old, it is my recorm~endation
that the City authorize the construction of th~ alternate components.
Should the City elect to re-bid the River's Edge Plaza alternate components, it is ~iifficult to
predict if bids would come in competitive With those previously received. Given the increase in
fuel costs, this has a direct impact on raw mater/al and equipment costs, however, it is difficult to
judge or predict the hungry factor of perspective contractors.
The project funding summary for the current contract (River's Edge Plaza base bid) is as follows:
Construction Contract
Contingency
Total Project Budget:
Renaissance Contract
$478,349.50
$ 59,076.60
$537~426.10
As presented in a previous memo, the projects costs have increased as a result of discrepancies
with the construction plans, incorrect "per plan" concrete quantities and design constmctability
issues. Additionally, staff was authorized to incorporate the application of the quarry red surface
hardener to the accent banding and cascading stairs, incorporate the cut limestone surface texture
to the concrete retaining wall, and install additional conduit and pedestals for future
telecommunications and power outlet applications. The following is a breakdown of the current
contract (base bid) projects costs:
Renaissance Construction Contract: $478,349
Cascading Stairs Foundation Walls: $ 15,500
Construction Quantities Adjushment: $ 40,000
Colored Concrete Surface Hardener: $ 16,000
Limestone Surface Texture, Retaining Wall: $ 11,250
Telecommunications/Power Conduit & Pedestals: $ 11,000
Electric Service Upgrade, 200 Amp: $ 5,000
Current Contract (Base Bid) Projected Cost: $5777100
Should you concur with the recommendation to authorize Renaissance proceed with the
construction of the alternate components, the project cost surm~ary for the River's Edge Plaza
project is as follows:

Total Projected Construction Cost:
BUDGETIMPACT
$478,349
$ 98,750
$121,289
$698.389
The current contract (River's Edge Plaza base bid) is approximately $39,700 over budget. Should
the City proceed with the alternate components, the total construction cost is projected at
$698,389, which is approximately $161,000 over budget. Upon reviewing the available funding
options with Pauline, there exists sufficient contingency in the remaining components of the
Riverwalk project to cover the overage.
ACTION STEP
Upon reviewing the River's Edge Plaza project with Barry, he has advised me that the City could
issue a change order to the existing contract and authorize Renaissance proceed with the
construction of the alternate components, and advise or request City Council concurrence via
Please provide direction on a course of action for the alternate component of the River's Edge
Plaza project. Should you have any questions, please advise.

SUBJECT: River's Edge Plaza Project Status
The purpose of this correspondence is to update you on the status of the River's
Edge Plaza construction and advise you of the anticipated increased cost associated
with the project.
Renaissance Construction has completed the lower foundation wall for the cascading
stairs and are continuing to construct the step perimeter foundation wails which
extend up to the plaza area. The contractor anticipates having the lower elevation
foundation walls, which are susceptible to spring river levels completed within the
next two (2) weeks. The contractor will then start construction of the cascading
stairs, beginning with the bottom lower elevation stair(s) and work their way out of
the potential high water areas.
According to the Corps of Engineers, within the weeks to follow, the river will begin
to rise as a result of the projected unseasonably warm temperatures and spring snow
melt to the north.
Over the past month, I have had several conversations and meetings with
Renaissance Construction, Architectural Concrete Systems (subcontractor) and BRW
to resolve discrepancies with the construction plans and to resolve design issues.
During this process, it was brought to my attention by the contractor that the
concrete construction quantities do not appear to be accurate. Given this, I decided
to check and recalculate the "per plan" concrete quantities. In doing so, I discovered
that the concrete quantities provided by BRW in the bid documents and subsequent
construction contract are not correct and do not accurately reflect the "per plan"
construction quantities. In recalculating the "per plan" concrete quantities and using
the contract unit prices, BRW under estimated the concrete quantities by
approximately $39,734.
The project funding summary for the River's Edge Plaza construction project is as
follows:
Construction Contract

Total Project budget:
Renaissance Contract
$478,349.50
$ 59.076.60

Based on the recalculated "per plan" quantities and using the contract unit prices for
the project, outlined below per bid item are the adjusted project quantities and the
associated contract cost adjustment.

I have informed BRW of the discrepancy in the plan quantities and forwarded copies
of my recalculation documentation for their review. BRW has concurred with my
recalculations and has yet to provide an acceptable justification for what I consider to
be an unacceptable error or omission.
BRW's response has been to provide what they call "value engineering
considerations" which would bring the project cost down to "near budget numbers"
by reducing the quantity of plaza constructed. BRW has proposed shortening the
cascading steps thus reducing the stair square footage and a potential saving of
approximately (;10,360. BRW also proposed reducing the width of the large curved
retaining wall from 24"(as bid) to 18" wide, which would potentially save (;21,946. ~
questioned BRW on the proposed wall modifications and they advised me that an 18"
wall design will be structurally sufficient and that the 24" wide wall was for
architectural esthetics.
The "value engineering considerations" proposed by BRW would not work because
the foundation walls for the cascading steps are partially in-place. Additionally, I
discussed the proposed wall modifications with Renaissance Construction and they
will not agree to a deduct of approximately 821,946 for the curved retaining wall.
The contractor's position is that certain cost are present including rented curved
formwork, reinforcing steel, labor and equipment and the concrete cost savings
would not offset the associated fixed costs. I concur with the assessment of the
contractor.
In an attempt to resolve discrepancies with the construction plans which do not
clearly show nor provide details for the construction of step perimeter foundation
walls, I directed BRW to revise the plans to include the necessary step foundation
walls and provide cross-sections for construction. Since the step perimeter
foundation walls are a required structural element and the construction plans failed to
provide adequate information for the contractor to include in their step square foot
unit cost, I have directed the contractor to construct the necessary step foundation
walls and authorize this work to be performed under an extra work item. The current
contract does not have a specific bid line item for cascading step walls thus the
contractor will be performing this work on a cost-plus basis. I have estimated the
cost of the extra work item to be in the range of $15,000.

It should be noted that the project has just begun and the contingency funding
allocated has been reduced from $59,076 to approximately $4,342. Additionally,
since the project is in such an early stage, there are certain unknown conditions
which may further effect construction quantities and potentially increase final project
costs.
