CITY COUNCIL AGENDA REPORT
JUNE 18, 2007
9A
JENNIFER WITTKOPF, PUBLIC WORKS COORDINATOR
CONSIDER APPROVAL OF A RESOLUTION APPROVING PLANS AND
SPECIFICATIONS AND AUTHORIZING ADVERTISEMENT FOR BIDS FOR
CONSTRUCTION OF THE WATER TREATMENT FACILITY
Introduction
The purpose of this agenda item is for the City Council to approve the plans
and specifications for the Water Treatment Facility and to authorize the
advertisement of bids for construction of the facility.
Historv
On August 7,2006, the City Council approved the City's Standardized Contract
for Professional Services with Bolton & Menk, Inc. and initiated the design
report for the Water Treatment Facility (WTF).
As part of the design report preparation, the Water Treatment Facility
Committee (WTFC) and the consultant completed a publiC involvement
process. From September to April, several neighborhood meetings were held
with residents to discuss various issues with the site and facility, including
exterior design and landscaping. Attendance at the meetings was primarily
limited to the residents living adjacent to the site.
Additionally, five issues of a project newsletter have been sent out to over 400
area residents. The City has also maintained a website and email distribution
list, to keep interested residents apprised of the latest project information.
The neighborhood's preference is for a building that has a residential
appearance and utilizes landscaping for screening and filtering of the building.
The WTFC feels that the concepts contained in the final design achieve these
goals while balancing the greater community's concerns of function and
budget.
On December 4, 2006, the design report was presented to the City Council for
approval. Issues considered by the Council at that time were:
Facility size I capacity
Building exterior architecture
Facility roof design I appearance
Equipment garage
Site fencing I security
Budget
The City Council accepted the design report and authorized preparation of the
plans and specifications for a 7.5 MGD WTF.

Current Circumstances
The WTF design plans and specifications have been completed and the next
step in the process is to advertise for construction bids. The proposed timeline
for the remainder of the project is as follows:
Approval of Plans and Specifications
Approval of Conditional Use Permit
Advertisement for Bids
Open Bids
Award Contract I Begin Construction
Compete Construction I Start-up

August 2007
February 2009
ISSUES:
The issues at this time include the following:
Conditional Use Permit - Staff submitted a CUP application to the Planning
Commission to be considered at the June 25 meeting. A CUP is required to
construct and operate the facility, a Public Service Structure, in the R1-LD
(residential) zoning area. It is important for the City Council to approve the
plans prior to the Planning Commission review. If Council requires any
changes to the plans at this time, those changes could affect the CUP
application.
The CUP requires that the WTF have 60% Class 1 materials on all sides in
accordance with City ordinances. The proposed facility meets this requirement
ranging from 61 % to 69% on the building. When reviewing the amount of
proposed Class 1 materials (brick and windows) on the facility this is an
important consideration as it is an indicator of the buildings cost effectiveness.
This demonstrates that while the facility is being constructed of quality
materials is not excessive in the use of Class 1 materials and is therefore
balancing cost concerns with aesthetics.
Proiect Schedule - The project schedule has been modified slightly since the
preliminary design phase. In general, the schedule was extended to give the
WTFC ample opportunity to obtain resident feedback about the facility and site,
and also to properly address on-site stormwater and wetland issues. Start-up
of the facility is still anticipated during the winter I off-peak usage season, early
in 2009.
Proiect Budaet - The estimated project budget reviewed by the City Council on
December 4,2006, was $14,336,000. Upon completion of the construction
plans and an estimate based on current construction costs, staff estimates the
total project Cost to be $14,553,000. This budget includes all construction and
design work associated with the WTF. The final budget will be dependent on
final bids and approval by the City Council on August 6,2007.
The difference in the current estimate and the December 4, 2006 estimate is
the contingency. The prior estimate included a $200,000 contingency. While
staff feels this is a sufficient contingency during construction we are concerned
that the volatility in steel and concrete prices could greatly impact the facility.
The WTF will have more than $6,000,000 worth of concrete and steel and
minor fluctuations in market prices could easily impact the cost of the plant.
For that reason staff has included an additional $200,000 in the current
contingency to cover those potential costs. If the additional funding is not
needed for construction staff proposes that the contingency be adjusted to
$200,000 as proposed in the WTF Report. The additional funding is available
in the Trunk Reserve Fund as that fund is responsible for 20% or $2,500,000
of the WTF non-storage related construction costs directly attributed to growth
capacity being built into the WTF.
Capital Eauipment Refund - The Minnesota Department of Revenue offers a
refund program for sales tax paid on capital equipment and appurtenances
used to refine or treat water to be sold at retail. Staff intends to work closely
with MN-Revenue to obtain sales tax refunds on all aspects of the facility that
apply. This could result in an estimated refund of $400,000 to $600,000
depending on final construction costs.
Staff recommends that any rebate be deposited in the Water Utility Fund and
used to offset the need for future water rate increases.
Enerav Efficiencies I Operational Cost Savinas -Included in the facility design
are features that are energy efficient and provide staff the opportunity to
operate the facility at a lower cost than standard equipment.
A diesel-fueled generator is included in the garage area of the facility. This
generator will be used as emergency back-up power for the essential
operations of the facility. The generator will also be used during peak energy
demand times, in conjunction with Xcel Energy's peak control program, to save
on the City's energy costs of running the facility. Staff is currently working with
Xcel to determine the cost savings to the City. Staff is also proposing to
include the Maintenance Center and Wells 8 and 9 in this program as the City
has generator facilities at each of those locations.
The pumps used to deliver the treated water into the City's system have
variable frequency drive (VFD) motors. VFD's can increase operating
efficiency by extending the productive life of the pumps. These also offer the
opportunity to run the pumps at a lower horsepower during low-demand
periods, thus using less energy. Xcel Energy also offers a rebate program for
motor efficiency that staff is currently researching.
