Re: City of Coppell
Village Parkway Pump Station Additions
Dear Mr. Daigre:
We are in receipt of your letter dated September 29, 1997, which indicates that G.E. Team Controls, Inc. has
completed the punch list dated September 26, 1997 and that the SCADA portion of your contract with the
City of Coppell is complete and ready for service. As such, we conducted a final inspection of the SCADA
system on September 30, 1997. In attendance were:
Mr. Matt Cast, City of Coppell
Mr. Larry Davis, City of Coppell
Mr. Ted Dutt, City of Coppell
Mr. Steve Baker, G.E. Team Controls
Mr. Gary Hendricks, P.E., S.J.& F., L.L.P.
The following items on the Sept. 261h punch list remain incomplete or not complete to the satisfaction of the
City:
1. Pump No. 4 is still in the pump rotation sequence. It is the lead pump in the 100% summer sequence.
Obviously, Pump No. 4 does not exist. Apparently, this causes none of the pumps to be called. Pump No.
4 needs to be removed from all pump rotation sequences set up and all sequences need to be test for
reliable operation of the system.
2. The Moore Road pressure point appears to still be reading a constant 50.0 psi no matter what is happening
in the system. This needs to be corrected. The City of Coppell understands this may be a problem at their
end. However, a coordinated effort to correct this problem needs to be a priority.
3. The City of Coppell still believes the external modem on the original SCADA computer ( Computer No.
1) is part of the equipment they supplied. Steve Baker could not confirm this at the time of our walk
through. This issue needs to be resolved prior to final acceptance of this portion of the contract.
4. Re-calibrate the pressure transmitters at the Ground Storage Tanks to match the 0-50 foot scale of the
Elevated Storage Tank so that the level trends of all three can be viewed on the same graph.

In addition to these items, the following items were reviewed and found to be in need of correction:
1. The City of Coppell provided us with a copy of the "Monthly Reports" print-outs at this meeting. This
was our first opportunity to review these print outs. In general, the information contained in the reports
contained no recognizable units and could not be readily compared to the data on the SCADA System.
However, even with this problem and using our best judgment as to the correct units on the reports, none
of the data seemed on the reports seemed to match the information we produced either from the SCADA
system or the circular charts. We marked up the corrections we could identify on the reports and gave the
originals to Steve Baker. A copy of our comments are attached to this letter for your records.
2. Larry Davis noted that the record drawings for the SCADA System have not been revised to show the
configuration of the second computer and how it is integrated into the system. Our brief review of the
drawings indicate at least three of the drawing will need to be corrected.
Although the original pump station contract was complete to the City's satisfaction prior to September 30,
1997, the SCADA System change order remains incomplete. As such, the City has directed us to inform you
that a contract deduction in the amount of $500 per day will be applied to the SCADA portion of your
contract, starting today October 1, 1997, and continuing unti! the SCADA System is complete in all respects,
acceptable to the City of Coppell and operating in a reliable manner. The City understands this subcontract
work by G.E. Team Controls is a specialty item and is primarily beyond your control. The City does not wish
to impart liquidated damages on North Texas Municipal Construction Co. Therefore, if you agree to the $500
per day SCADA deduction, a change order will be issued upon final acceptance of the SCADA System which
will include the total SCADA System deduction, and a contact time extension will be granted. A preliminary
copy of the proposed change order is enclosed for your review.
Please review this interim agreement and notify us of your acceptability by signing in the space provided
below. If you have any question or wish to discuss this proposal further, please do not hesitate to contact this
office.

Kerl:
Fake a look at this draft letter and change order to see if it meets the intent of our meeting yesterday. Ken,
since we are changing the intent of the original "gentlemen's" agreement we discussed with Mike, I thought
both you and he would like this one to be a little more formal. Therefore, I have included an acceptance block
for the contract at the end of the letter. L~t me know if you think this is necessary.
