Re: Village Parkway Ground Storage Reservoir No.
Change Order Number 1
Dear Mr. Davis:
As discussed in our January 23, 1996, meeting with the City of Coppell and Natgun Corporation, a possible
method of resolving the outstanding payments due Gee Consultants, Inc. is through a negotiated change order
that provides for some of the payment by the City with the balance to be paid by Natgun. Enclosed is a copy
of proposed Change Order No. 1 and Richard Gee's invoices sent to Natgun. The payments due Gee
Consultants, Inc. are a result of over time charges on the continuous inspection of piers, the Saturday concrete
floor placement and the additional technician need for the casting of the dome and wall panels. The current
agreement between the City and Gee Consultants, Inc. dose not provide for any overtime expenditures.
On the September :25, 1995, invoice it is our opinion that the City may pay for regular time pier inspection
cancellations and Natgun should pay for all overtime associated with the continuous pier inspections and
overtime pier inspections cancellations. The following is a summary of payment due Gee Consultants for the
September 25, invoice.
· September 2S~ 199S: Total Amount due $734.42
City of Coppell Change Order No. 1: $282.62
Natgun Payment For Difference: $451.80
On the September 26, 1995, invoice it is our opinion that Natgun should pay for all overtime charges
associated with the continuous inspection of piers. The following is a summary of payment due Gee
Consultants for the October :26, invoice.
· October 26, 1995: Total Amount due $712.84
Natgun Payment For Overtime: $712.84

On the November 27, 1995, invoice it is our opinion that the City may pay for regular time pier inspection
cancellations and Natgun should pay for all overtime associated with the continuous pier inspections and
overtime pier inspections cancellations. The following is a summary of payment due Gee Consultants for the
November 27, invoice.
· November 27, 1995: Total Amount due $300.32
City of Coppell Change Order No. 1: $ 66.94
Natgun Payment For Difference: $233.38
The December 26, 1995, invoice includes the overtime associated with the Saturday, December 9, 1995,
1700 cubic yard concrete tank floor placement. The Saturday pour was at the request of the City and it is our
opinion that the City may pay for the overtime. The following is a summary of payment due Gee Consultants
for the December 26, invoice.
· December 26, 1995: Total Amount due $339.86
City of Coppell Change Order No. 1: $339.86
The January 26, 1996, invoice includes charges for concrete mix inspection, overtime concrete mix
inspection, trips to the site, additional concrete cylinders and cylinder molds for field hold cylinders· Natgun
has agreed to pay for concrete cylinders and concrete molds for field hold cylinders. It is our opinion the
Natgun should also pay the additional charges for overtime and the City may pay for the concrete mix
inspection and trip charges. The following is a summary of payment due Gee Consultants for the January 26,
invoice.
· January 26, 1996: Total Amount due $4,852.26
City of Coppell Change Order No. 1: $2,999.82
Natgun Payment For Difference: $1,852.44
Based on our opinion of payment for the outstanding balances due Gee Consultants, Inc., we recommend the
City pay a portion of the balance through a negotiated change order in the amount of $3,689.24, with the
difference of payment made by Natgun Corporation in the amount of $3,250.46. Natgun has identified
additional potential costs in the amount of $3,260.00 for additional dome concrete testing, a shotcrete test
panel and additional shotcrete testing for the remaining portions of the project. IfNatgun requires the
additional testing for any of these items to assure or guarantee the finished product, we recommend it be at
their own expense.
Please review the enclosed Richard Gee invoices and our suggested change order amount and notify us if the
proposed Change Order No. 1 is acceptable to the City.
We are available to discuss the proposed change order further at your convenience· 7 ~ ;
