Council Report 99-142
Approve Engineering Services Agreement
Water Tower Repainting
Staff recommends the adoption of the following motion: Move that Council authorize the City
Manaaer to enter into an aareement with SEHRCM for the enaineerina services related to the
reoaintina of the Moline Water Tower.
Overview.
The Moline Water Tower was built in 1967, it was painted Sky Blue. The second time the
tower was repainted was in 1977. It was repainted for the third time in 1987. The tower was
sand blasted down to bare metal to remove all of the .. Red lead Primer" and a new primer
system was applied to the tower. The paint color that was applied was a custom blend and it
was named U Hopkins Grey u. The paint system that was applied has failed and is in need of
repainting. The tower has some other work scheduled to be completed during the repainting
of the tower. The new paint system that will be applied should last another 10-12 years and
possibly longer because of the new technology that Is available now.
Primary Issues to Consider.
. What is the estimated project cost? City cost?
The estimated costs should be covered by the $500,000 that was entered into the Capital
Improvement Plan. The cost of Engineering services is $45,220.
. Project schedule
Complete design: October-November, 1999
Award project: December-January, 2000
Construction: April, 2000
. Engineering Selection Process and SEHRCM engineering fees
Engineering proposals were solicited from three firms. We received proposals from all three
companies. Two of the companies are engineering companies that specialize in tower
painting inspections these companies are: AEC Engineering and KLM Engineering. The
other company is a full service engineering that covers all the aspects tower construction and
painting. The staff selected SEHRCM based on their Qualifications, and because RCM
designed the water tower originally. RCM was the engineer of the Well # 1 remodeling
projec~ and numerous other water related projects in the past. SEHRCM fees are $45,220,
which includes $32,320 for construction services. The City receives a 5% reduction or $2380
off the construction fees because of our award of the Water Treatment Plant # 4 work to
SEHRCM. Some of the factors that led the selection of SEHRCM were, their offices are less
than 10 minutes away so that problems can be resolved Quickly. All of the other cities that I
talked to highly recommended SEHRCM and were very pleased with the out corne of their
painting projects on their water towers. The colors that are being considered are the
Minnetonka Ridgedale Tower "Cumulus" or 51. Louis Park Towers 'Warm Sun".

Moline Water Tower Award
SEH No. P-HOPKN9908.00 WATER
This memo regards our phone conversation concerning award of engineering and inspection services for
the Moline Walenower Reconditioning.
As discussed SEH will offer the City of Hopkins a direct fee reduction of $2380.00. or 5% for being
awarded the Water Treatment Plant No.4 work per our proposal. This reduction places our fee at
$45,220.00. It is our belief that fees regarding Pre-Design should remain. However, as outlined in our
letter of June 29, 1999, our fees are based on an hourly not-lo-exceed. Therefore. further reductions to our
fee may be realized by the City in the form of reduced time for preparation of the construction documents,
and/or inspection lime depending on which contractor is awarded the project.
We believe we have provided the City with a proposal that is all inclusive of the anticipated work for this
project, and apprecialed the opponunity for further discussion.

Work Plan - 2 MG Moline Water Tower
After review of the dive inspection videos, as conducted by Liquid Engineering
(LE), it is our assessment that it is in the best interest of the City of Hopkins to
complete a total reconditioning of this facility. It is estimated that completion of
this project will take 12 weeks.
As discussed in our transmittal letter, that even if the exterior coating system is
found not to be lead or chromium based, MPCA will require a containment
structure to capture fugitive dust emissions. This is providing that some
variation of a conventional abrasive blast method is used. However, this tanks
configuration lends itself well to the use of a "vertical vacuum blast" system.
The Wheelabrator system provides for coating removal that utilizes both grit and
steel shot without the necessity for erecting an enclosure, since generated waste
is collected by a vacuum arrangement. Furthermore, generated waste is
significantly minimized because the abrasive is continuously recycled.
Use of this system though is limited in use to the shell plate sections of the tank
structure. Therefore, the "vertical vacuum blast" system would be used in
conjunction with other available and approved methods to accommodate the
roof and pilaster surfaces. SEH/RCM introduces this alternative, based on our
interpretation of existing data and inherent site considerations, as a means of
offering the City of Hopkins a cost efficient solution.
SEH.RCM believes that the key to achieving desired expectations will lie in the
successful scheduling, communication, and coordination between Hopkins City
staff and the SEH.RCM project team. We are prepared to complete construction
documents in line with the City's expectation to bid the project in November of
this year. This early start will enable the City to take advantage of open
contractor schedules for the 2000 construction season- attracting more bidders-
and those most qualified to complete the work. Early planning will allow us to
plan around special concerns directly related to this project:
... Consideration of wireless communications antenna and ground equipment
... Proximity to STH 169 and Excelsior Boulevard
... Water demands during tank down time
As earlier stated, SEH/RCM will work directly with City staff, MPCA, and other
concerned parties during pre-planning to address these specific issues.
Pre-Design
In this phase of the project, SEH.RCM will complete a final study of the
structure and site as described in the General section of the General Scope of
Work. Following this investigation, we will meet with City staff to formulate a
formal project plan to meet long-term facility maintenance expectations.
As requested, SEH.RCM will provide the City with copies of specific
documentation used in the process of developing the project plan.

General Scope of Work, cant.
Design
SEH-RCM will incorporate into its design plan required tank modifications as
determined through further field investigation, outlined in the pre-design.
Modifications already determined include:
... Addition of an exterior access ladder
... Repair of the interior ladder (with safety climb device)
... Grout replacement around the foundation
... Catch basin under the overflow outlet pipe
... Removal of approximately 30' of pipe and valve from the upper tank which
fills the standpipe
... Upgrade of the electrical system
Tank modifications, including pre-surface preparation, will enhance the
serviceability of the newly applied coating system by reducing and/or
eliminating defects where failures begin. These changes will also provide safety
measures for future tank servicing and maintenance in compliance with current
A WW A and OSHA safety guidelines.
The inspection report and supplemental videos, as prepared by Liquid
Engineering, do not furnish adequate information on coating thickness,
condition of supporting roof rafters, and number of roof supports with respect
to the tank interior. SEH-RCM will incorporate provisions into the specifications
to address these items so that change orders in reference to these issues will be
less likely.
SEH-RCM will review, with City staff, the current operation of its water system
to assist in determining the safest and most efficient means of continued
operation while the tank is temporarily removed from service.
Environmental Concerns
Specific information regarding the interior and exterior coating systems, again,
will be analyzed as part of pre-design. Paint chip sampling will determine if the
existing coatings have residual lead or contain chromium to a level which would
render them as hazardous.
However, SEH-RCM will provide specifications in accordance with current
MPCA air quality regulations covering the emission of fugitive dust apparent
during the coating removal process. Although the removed coating systems may
not be classified as lead and/or chromium based, SEH-RCM will provide
measures for TCLP (Toxicity Characteristic Leaching Procedure) testing of
generated waste to identify materials for disposal as hazardous waste. Personal
air monitoring in accordance with OSHA "Lead in Construction" guidelines will
also be implemented. These safeguards are incorporated into the specification
as an additional means of liability protection for the Owner.

Inspection
As presented under our General Scope of Work, SEH.RCM will provide an
inspector trained to observe and work under the guidelines on NACE, SSPC
and A WS. Our inspectors are also A WS and/or SSPC certified, and will provide
observation during key phases of mobilization, structural modifications, and the
reconditioning of the tank's coating system. SEH inspection services will
include both full and part-time construction observation as necessitated by site
activities. Full-time inspection will be provided during critical activities such
as surface preparation for both interior and exterior surfaces. of the tanks.
SEH.RCM believes in the importance of field inspection to assure our clients
a quality product. Therefore, we propose a substantial presence during the
entire project. This commitment will enable us to take a proactive role in
addressing any difficulties which may occur during the length of the project.
