DATE
Each year in accordance with requirements from the Texas Natural Resources Conservation Commission
(TNRCC) the City of Coppell has divers enter our elevated storage tanks and ground storage tanks to make a
video record of the status of the interior of the tanks. Also, any problems associated with the tanks are noted
during the inspection of the interior of the water tanks. For several years now there has been concern about
deterioration of the interior of the 1.5 million gallon elevated storage tank on Southwestern Blvd. However,
because that was the only elevated storage tank within the City of Coppell there was not an opportunity to
take it out orsentice to perform any type of remedial action to correct the problems. With the new 2 million
gallon elevated storage tank in service we budgeted funds to take the 1.5 million gallon elevated storage tank
out of service to perform interior modifications which for the most part include a thorough cleaning of the
interior of the tank. This includes the removal of any rust, paint, coating, etc. and reapplying a coating on
the interior of the tank. This work is classified as a maintenance operation necessary to maintain the long-
term usability of the elevated storage tank.
Staff recommends approval of the contract with Shimek, Jacobs and Fh~dea in the amount of $20,800.00 so
that ~ds project can proceed and hopefury be completed prior to spring 2000, when
Staff will be available for questions at the Council meeting.

Re: Interior Painting of the 1.5 Million Gallon Elevated Storage Tank
Engineering Services Proposal
Dear Mr. Griffin:
In accordance with your request, we propose to furnish engineering services for the preparation of plans and
specifications, construction administration and paint inspection services during the interior blasting and
coating operation for the re-coating of the 1.5 Million Gallon Elevated Storage Tank. The primary scope is the
re-coating of the interior of the tank and the addition of a motor operated control valve capable of being
monitored and controlled by the City's SCADA system. Mr. Glen Hollowell has explained the City's desire to
complete this project in advance of the peak water demand season. Therefore, we anticipate establislfmg a 30-
day re-coat window and tank downtime in the contract documents. Our opinion of probable constraction cost
for the interior repaint is in the range orS115,000. The anticipated cost for the installation of the motor
operated control valve is in the range orS10,000 to $12,000.
We understand you may want to evaluate an additive alternate bid for the re-coating of the interior tank
column and that at some point in the near future the City is considering re-coating the exterior of the tank.
Accordingly, we propose to conduct an interior and exterior paint inspection of the tank column and an
exterior inspection of the tank bowl. Our inspection of the tank coating system will be presented in written
report explaining our findings and recommendations.
Our scope of services for this project will include the following:
Basic Services
· Preparation of a site plan, which will show the proximity of adjacent structures and the workspace
available to the successful contractor.
Prepare specifications for the interior repaint of the tank bowl with an additive alternate for the
repainting of the tank interior column. This specification will include dehumidi~eation in an attempt
to shorten the window of having the tank out of service.
Preparation of the plan and specification for the installation of a 20-inch motor operated valve to
replace the existing 20-inch gate valve in the inlet pipe to the tank.
